These cosmetics may cause cancer
These cosmetics may cause cancer. In real life, many people often use cosmetics and buy cosmetics. Cosmetics have become a necessity for many female friends. I will share them below An article about these cosmetics or cancer-related information. Let’s take a look! These cosmetics may cause cancer 1
Recently
the Guangdong Provincial Food and Drug Administration released
a batch of cosmetics sampling information
***Sampling 249 Batches of cosmetics
8 batches of unqualified samples
Involving many well-known brands
Test results show that the initial arsenic content of a certain brand of facial cleanser was 3.8mg /kg, inorganic arsenic is listed as a class I carcinogen by the International Agency for Research on Cancer. The "Safety and Technical Specifications for Cosmetics" requires that the standard limit of arsenic is 2mg/kg, and this cleanser exceeded the standard by 0.9 times.
Water code cleanser and Schwarzkopf hair dye mousse are unqualified
Water code Ying sold by Shenzhen Renrenle Commercial Co., Ltd. in Xuefu Shopping Plaza and produced by Guangzhou Keneng Cosmetics Research Co., Ltd. Bright whitening facial cleanser, the arsenic content detected value in the initial test and re-test was 2.9mg/kg;
It is sold at Xiayuan Store of China Resources Vanguard Life Supermarket (Guangzhou) Co., Ltd. and is sold by Guangzhou Science and Technology Co., Ltd. The arsenic content of the Water Code Ying Bright Whitening Cleansing Milk produced by Neng Cosmetics Research Co., Ltd. was 3.8 mg/kg in the initial test and 3.3 mg/kg in the re-test.
Schwarzkopf hair dye mousse sold at the Baiyuntanghui branch of Guangdong Wanning Commercial Chain Co., Ltd. was found to have unidentified hair dye on the label: 4-amino-2-hydroxytoluene.
What are the dangers of excessive heavy metal levels?
In recent years, many cosmetics have been exposed to excessive levels of heavy metals. Heavy metals in cosmetics mainly refer to the four types of arsenic, lead, mercury, and cadmium, and regulations require that these four types be detected. If you use products with excessive heavy metals for a long time, heavy metals will accumulate in the body and have certain carcinogenicity.
According to the "Technical Specifications for Safety of Cosmetics", the standard limit of arsenic is 2mg/kg. It can be deduced that the arsenic content of the above two batches of water code cleanser exceeds the standard by up to 0.9 times.
Arsenic is divided into organic arsenic and inorganic arsenic (collectively referred to as total arsenic). Inorganic arsenic is closely related to the long-term effects on human health and has been listed as a carcinogen by the International Cancer Institute (that is, there is sufficient carcinogens with epidemiological evidence in humans).
Relevant production and operation enterprises have been put on file for investigation
It is understood that for unqualified cosmetics during supervision and sampling inspections, the Guangdong Provincial Food and Drug Administration has organized relevant market supervision and administration bureaus in the province to investigate according to law Conduct investigations on relevant production and operation enterprises, order them to recall substandard products, and find out the quantity and flow of substandard products; for cosmetics that are verified to be counterfeit, the purchase channels of relevant operating enterprises must be traced, and the production and sale of counterfeit and shoddy cosmetics shall be severely cracked down on. Illegal conduct.
The Guangdong Provincial Food and Drug Administration reminds consumers:
You should purchase cosmetics through legal channels and check whether the purchased cosmetics have obtained special-purpose cosmetics approval documents or non-special-purpose cosmetics registration certificates, etc. Information, request and retain relevant consumer receipts. If you find suspected illegal products, please report them promptly. Complaint reporting hotline: 12315.
Specific unqualified 8 batches of cosmetics
The list is as follows
These cosmetics may cause cancer 2
Which cosmetic ingredients are toxic or carcinogenic?
When you saw this question, were you surprised? Many children’s shoes still have many worries about cosmetics, especially the toxicity and carcinogenicity of ingredients. In order to calm everyone's mood, first of all, let me give you a reassurance: under the current circumstances, we do not need to worry about the so-called toxicity or carcinogenicity issues in cosmetics.
Toxicity and dose
As we all know, there is a saying that "talking about toxicity without talking about dose is just a hooligan."
This conclusion is basically correct, because everything in daily life, as long as it has physiological effects, can be said to be toxic to a certain extent. To give a simple example: some people drink alcohol every day. Alcohol itself is toxic. Although drinking a small amount of alcohol is pleasant, excessive intake of alcohol can cause serious damage to nerves and various cells and tissues of the human body, especially the liver. This is toxicity. performance.
Another example is that without salt, there is no fun in eating vegetables. but. . . . Eating too much salt can also have toxic effects.
Toxicological term—LD50
So when we measure whether a substance is toxic, we need to introduce some basic concepts of toxicology, one of which is LD50 (ie: half lethal dose), it means that when we feed a certain substance to mice or other animals, when the intake/exposure reaches a certain level, it may cause 50% of the mice, this dose is half Lethal dose.
Figure 2 Half lethal dose (Source: /doc/53a226f3c9fa6ed4ed169c15)
The lower the LD50 value of a certain substance, the more toxic it is. In practical applications, the dose or exposure to a substance must be taken into account when considering toxicity. Numerous substances are toxic at high concentrations; but at low concentrations, they exhibit other physiological activities or do not exhibit any toxic effects.
The actual dose is closely related to the route of exposure. For example, some powdery substances are non-toxic and harmless when applied to the skin or even eaten - such as flour - but the lungs It is toxic if inhaled. Typical examples in cosmetics are titanium dioxide and sunscreen spray.
Fortunately, with the accumulation of experience, the advancement of toxicological research, and the increasingly stringent regulations, toxic or carcinogenic substances in cosmetics have basically been eliminated.
Our country has implemented the strictest cosmetic raw material management system in the world, no one! There is a de facto white list, the "Catalogue of Used Cosmetic Raw Materials", and a list of prohibited and restricted substances.
Prohibited ingredients are ingredients that may cause toxicity, excessive allergenicity, phototoxicity, reproductive teratogenicity, carcinogenicity, etc. at a certain dose. Because they have been excluded from the ingredients allowed for use in cosmetics, it can be said that the safety of the substances in the ingredients list of cosmetics currently on the Chinese market (as long as they are not illegally added) is guaranteed after long-term use.
Limited amounts of added ingredients, such as preservatives and sunscreens, have their own upper limits for use. These ingredients are also subject to strict supervision. Under normal usage amounts and usage methods, everyone basically does not have to worry about their toxicity.
How to choose cosmetics
The above conclusion does not mean that everyone can use cosmetics at will, because everyone’s skin condition and skin type are different, so you must first choose according to your own skin condition and skin type. Quality and needs, choose the product that suits you better. Because a safe ingredient may not be applicable in some cases, this... you understand, right?
Secondly, in addition to having basic knowledge of cosmetics and chemistry, more importantly, pay attention to monitoring skin changes in daily use. For example, when using a new product for the first time, you should be more cautious. You can try it out first to make sure you have no problems, and then expand it to a larger area and use it for a longer period of time (see: 6 tips to prevent adverse reactions to cosmetics).
In addition, there are some ingredients that are relatively irritating. The most common ones are the popular retinol. If the concentration is too high, the so-called "retinolization" phenomenon will occur. A considerable number of people may experience irritation, scaling, and redness after use. After this happens, if you can overcome it, then persevere; if you can't, don't bear it. Similar problems may occur with some acid products, such as fruit acid, salicylic acid, etc. Therefore, you should pay attention to whether it is suitable for your skin condition and whether you are using the appropriate concentration. Do not blindly pursue high concentrations!
There are not many such ingredients now. Because as a product of a cosmetics company, if users continue to complain about adverse reactions after sales: "This product has adverse reactions after use" or "I feel very irritated", the product will not be sold and the evaluation will not be good, so Manufacturers will also continue to improve their formulas.
One thing that needs special reminder here is that the skin of Chinese people is very different from that of European, American and African people (see: The stratum corneum of different races is actually different? If you love skin care, you may not have heard of it yet) ), therefore cosmetics that work well in those countries/regions, especially some strong medicines, may not be suitable for Chinese people. Don’t blindly pursue “strong medicine” from abroad!
Wrong identification methods
There have been some popular methods on the Internet to identify whether cosmetics contain carcinogenic or toxic substances, such as burning a cosmetic with fire, or dropping it in water and observing the ups and downs. Wait, this is an old anecdote.
Cosmetics that may contain raw materials from coal tar or other petrochemical sources are of widespread concern. To be precise, before the 1970s, due to poor petroleum refining technology, certain raw materials derived from petroleum or coal may be mixed with a certain amount of polycyclic aromatic hydrocarbons, which are indeed carcinogenic and comedogenic to the skin. Moreover, polycyclic aromatic hydrocarbons are toxic, especially when inhaled, and can cause great harm to humans.
With the development of technology, these ingredients have been eliminated from cosmetic raw materials, and manufacturers are unlikely to use low-purity raw materials. Many of the so-called identification methods in the past were indeed IQ taxes.
This series will continue to focus on the ingredients and formulas of cosmetics, and explore products suitable for use according to different skin types; or situations where certain ingredients may not be suitable.
Review of knowledge points
1. Toxicity is relative. Dose and route of exposure should be considered when discussing toxicity. An important mutualistic concept for measuring toxicity is the LD50 (median lethal dose). The lower the LD50 value of a substance, the more toxic it is.
2. When choosing cosmetics, you must first choose according to your skin condition, skin type and needs; secondly, pay attention to monitoring skin changes in daily use to avoid adverse reactions.
3. Retinol and other products used in too high a concentration will cause "retinolization", resulting in irritation, scaling, and redness. Some acid products, such as ific acid and salicylic acid, etc. There are such problems. The skin of Chinese and foreign races is different, so don’t blindly pursue high-concentration “strong medicines” from foreign countries.
4. It is impossible to identify whether cosmetics are toxic by burning them or dropping them in water to observe their ups and downs. These cosmetics may cause cancer 3
It is irresistible, but news about cosmetics causing cancer is not uncommon. The most recent exposure is the perfume that is loved by fashionable men and women. According to a survey report conducted by the Beijing Center for Disease Control last year, 90% of perfumes were sampled and found to contain "phthalate" substances, which may cause cell mutation and even cause cancer. However, our country has no content limit standards for this substance. Not only are perfumes toxic, take a look at the cancer-causing effects of these beauty cosmetics.
Cosmetics are a necessity in every woman’s life. Hairdressing, eyebrow tattooing, whitening, freckle removal, lip beauty, breast enhancement, etc. are all inseparable from cosmetics. However, cosmetics are all chemical synthesis. Although they have the function of protecting and beautifying the human body, they also volatilize various harmful substances that are harmful to health.
The American Herbal Association believes that more than 60% of skin care ingredients will enter the body through the surface layer of the skin. In other words, if cosmetics contain toxic or synthetic ingredients, it will aggravate the detoxification of the heart, liver, kidneys, etc. burden on the organs, thereby endangering health.
A British research report in October last year pointed out that British women use cosmetics the most among European countries. They spent about 6.4 billion pounds on various cosmetics last year, using an average of 12 kinds of cosmetics every day, including There are at least 175 kinds of chemical substances, and the average person absorbs about 2.25Kg of chemical substances through the skin or mouth every year.
Therefore, if cosmetics are used improperly or abused, they will harm health. At least they will cause irritation to human skin, and at worst, they will cause "cosmetic dermatitis", even induce cancer and endanger life. In this way, makeup and beauty will not only Getting the results of beauty becomes a trap of beauty makeup. It can be said that cosmetics are a fatal temptation!
Temptation 1: Makeup removal
Cosmetics contain a variety of chemicals, the most worrying of which are preservatives belonging to the paraben class. Statistics show that 99% of makeup products and 77% of makeup removers contain parabens. Parabens disrupt hormones.
Evidence shows that they mimic the female hormone estrogen and may increase a woman's risk of breast cancer if she is exposed to it throughout her life. A study shows that hydroxybenzoic acid appears in up to 90% of breast cancer tissue samples and may also harm male fertility. Most of the flavors and pigments contained in cosmetics are synthetic products made from coal tar, and some are carcinogenic. Some hormonal cosmetics also seriously affect human health. For example, hormonal skin care creams can make the skin white, tender and smooth temporarily. Once they are stopped, more wrinkles will appear, making the skin look shriveled and old. Eyelid ointments and facial creams contain talcum powder, whose molecules are very similar to asbestos. When used, they escape into the air and enter the lungs with breathing, which can cause respiratory problems, asthma and even lung cancer.
Another troublesome chemical is the antibacterial and insecticide triclosan. It is widely used in toothpastes, soaps, household cleaning products and body washes. Triclosan belongs to the class of chlorophenols that may cause cancer.
Temptation 2: Hair dyeing
Long-term and frequent use of hair dye may cause permanent damage to the human body. Because in the process of hair dyeing, a large amount of oxidants such as hydrogen peroxide, sodium hyposulfite, formaldehyde or reducing agents such as sodium bisulfite are used, which will cause certain damage to the hair and scalp, causing pityriasis (dandruff) on the scalp. ), scalp seborrheic dermatitis and contact dermatitis. Benzene chemicals and heavy metal salts in hair dyes can also be absorbed through the skin. After repeated and long-term exposure to these substances, these toxic substances accumulate in the body, damaging the hematopoietic, liver, kidney and other systems, which is harmful to the human body. causing permanent damage. Therefore, some studies have found that common mutagenic substances contained in hair dyes can be found in the urine of women who dye their hair, suggesting the possibility of causing cancer after hair dyes are absorbed by the hair. The American Cancer Society recently conducted a survey of 13,000 women who dyed their hair and found that they were 3.8 times more likely to develop leukemia than women who did not dye their hair. Moreover, women who use hair dyes are 70% more likely to develop lymphoma.
Temptation 3: Perm
The principle of a perm is to use a strong alkaline perm to destroy the tissue bonds of the hair to form a new hairstyle. If you perm your hair when the hair quality is not good, the harm of the medicine to the hair will be greater.
The main ingredients of perm are thioglycolic acid and p-phenylenediamine. Thioglycolic acid substances can easily invade the body through the skin, are highly irritating to the skin and mucous membranes, have a strong destructive effect on the surface layer of the hair, and are mutagenic. Para-phenylenediamines are toxic substances that are highly irritating, allergic and toxic to the human body. They can cause allergies, increased scalp and even hair loss. Long-term use can accumulate and cause greater harm to the human body, and even Can cause skin cancer, leukemia, bladder cancer and other cancers.
Temptation 4: Whitening and freckle removal
In order to achieve the specific effect of whitening and freckle removal, whitening and freckle removal cosmetics often add some special functional ingredients, such as kojic acid, which can inhibit tyrosine in the human body. The activity of kojic acid enzyme can control the pigmentation of the skin. However, excessive dosage of kojic acid can cause white spots on the skin and be accompanied by irritation, and the chemical properties of kojic acid itself are also unstable. The pyran in the molecular formula of kojic acid is a directional compound like benzene, and is theoretically as carcinogenic as benzene; the hydroxyl group in kojic acid can also cause the accumulation of free radicals in the human body, which is also carcinogenic. . Therefore, the Japanese government prohibits the import and production of cosmetics containing kojic acid.
In addition, whitening and freckle removal cosmetics contain lead, mercury, fruit acid, etc. These special ingredients are highly irritating and dangerous. In order to achieve better publicity effects, some unscrupulous businesses often add excessive heavy metals to cosmetics. For example, excessive metallic mercury can enhance the whitening and freckle removal effect. In fact, national regulations stipulate that the mercury content of cosmetics shall not exceed 1 mg/kg, the arsenic content shall not exceed 10 mg/kg, and the lead content shall not exceed 40 mg/kg. Exceeding the standard can easily cause poisoning and cause symptoms such as neurasthenia, fatigue, insomnia, irritability (mercury), or pigmentation, pain (arsenic), constipation, and anemia (lead).
Temptation 5: Beautiful lips
Most women like to wear lipstick, lipstick, etc. to beautify their lips, but when using lipstick and lipstick, they should also pay attention to prevent harm to their health.
The main ingredients of lipstick are lanolin, wax and dye. Due to the complex composition of lanolin, it is easy to cause allergic reactions, such as dry cracking and peeling of the lip mucous membrane, and sometimes itching or slight pain on the lips; lanolin It also has strong adsorption properties and can adsorb dust, bacteria, viruses and some heavy metal ions in the air to the lip mucosa. The alkaline rosin in lipstick, eosin and flame red in rouge are all highly carcinogenic. Coal tar and other dyes used in all lipsticks are terrible carcinogens, and the amount of this substance in lipstick has greatly exceeded the amount allowed in food. Non-bleaching lipsticks have strong fixatives added to make the pigment adhere to the lips, so be careful. Human lips themselves have mucous membrane tissue, which has a certain ability to absorb harmful substances, causing them to invade the body. At the same time, when people talk, drink tea, or eat, they will inevitably bring lipstick, lipstick, and lip attachments into their mouths unintentionally, causing them to directly enter the human body, thus endangering health. According to relevant foreign data, among young female cancer patients, 18.2% of the causes are related to the application of lipstick and lipstick.
Temptation 6: Breast enlargement
Most breast enlargement creams contain hormones such as "diethylstilbestrol", etc. Although they can make breasts rapidly enlarge, firm and elastic, women with flat chests will not use them after using them. There will be obvious effects, but this effect is only short-lived. Regular use will cause a large amount of estrogen to accumulate deep in the skin, which can cause endocrine disorders, irregular menstruation, pigmentation, skin atrophy, etc. Especially for girls with normal menstruation, there is no lack of estrogen in the body. If a large amount of estrogen is artificially used for breast enlargement, it will inhibit the secretion of estrogen in the body. The result is self-defeating and inhibits breast growth. development. For women with a family history of breast cancer or cervical cancer, the risk of cancer may be increased.
Use during pregnancy may also increase the risk of fetal cancer.
Temptation 7: Manicure
Since ancient times, nail modification has been an important part of female beauty. Improper application of nail polish may also cause damage such as paronychia by irritating the nail grooves.
Nail polish mainly consists of three parts: pigment, solvent, and penetration enhancer. Conventional nail polish formulas generally include the following ingredients: pigment, nitrocellulose, lemon acetyl tributyl ester, phthalates, ethyl acetate, butyl acetate, ethanol, and toluene. Among them, the pigments are fired from potassium silicate, magnesium oxide, iron oxide, aluminum oxide, etc. according to the required color. Certain pigments, solvents and penetration enhancers in nail polish, such as ethanol, benzene, ketones, etc., can damage the nail plate after long-term use, leading to brittle nails, longitudinal nail ridges, yellow nails, nail malnutrition and other damages. Improper application can also cause It may cause damage such as paronychia due to irritation of the nail groove. Benzene and benzene substances, if used for a long time, may also cause damage to the respiratory system and are suspected to be carcinogenic.
In addition, many women like to change nail polish frequently. Before using new nail polish, they usually use nail polish remover to remove the previously applied nail polish. Nail polish removers are generally powerful organic solvents composed of acetone, ethyl ketone, ethanol, etc. Their use will also cause greater damage to nails.
Temptation 8: Using perfume
At least more than 5,000 chemical ingredients are needed to make fragrances. Each perfume contains more than 600 chemical components. Among these more than 5,000 chemical ingredients, less than 20% have undergone toxicity tests. The results are that they are all toxic and have been classified as dangerous goods by many countries. Studies have found that the chemical components of fragrances are harmful to health, especially the skin, lungs and brain. Many people complain about side effects such as nettle rash and dermatitis after using fragrances. Aromatherapy has a great impact on patients with chronic lung diseases, especially asthma. According to statistics, in the United States alone, up to 75% (approximately 9 million patients) of asthma cases are induced by perfume.
Ecotoxicologists have concluded through research that the artificial musk contained in perfume can completely lose the defense ability of human cells against foreign harmful substances. For this reason, experts remind people that although perfume is fragrant, it is harmful to health. Germany already has a voluntary ban on synthetic fragrances in effect; in Japan, most synthetic chemical fragrances similar to artificial musk have been banned.
Perfume contains volatile aromatic hydrocarbons, which are very harmful to the human body.
The latest research shows that linalol, a component rich in perfume or other fragrances, can induce depression, depression and even life-threatening effects. In particular, some unqualified and low-quality perfumes not only have inferior and harmful raw materials, but also the manufacturing process of these perfumes often does not meet hygienic standards. Using such perfumes is more likely to make people feel dizzy and nauseated, and may cause serious consequences if used for a long time. Such as dull sense of smell, weakened vision, etc. The harmful chemical components of perfume will pollute the air breathed by the children around you. Over time, it may cause children's inattention, learning difficulties, hyperactivity, and in severe cases, convulsions and developmental delays. Wait for the consequences.
Advice: Use cosmetics healthily and stay away from cancer-causing cosmetics.
1. Choose high-quality cosmetics: First, pay attention to check whether the cosmetics have trademarks, production dates, production company names and health license numbers. Pay attention to whether the cosmetic packaging is intact, whether the contents have any peculiar smell, and whether there are changes in properties, such as whether there are oil and water layers, bubbles, etc. in cream products. When choosing medicinal cosmetics, you should also pay attention to whether the product has a special purpose cosmetics approval number from the health department. To prevent the harm of toxic substances such as mercury and carcinogens in cosmetics, you should choose high-quality products approved by the Ministry of Health.
2. Don’t believe in advertisements: especially advertisements such as “100% curative effect” and “effective in three days.” my country stipulates that the use of 347 types of substances such as estrogen, chlorine, arsenic and arsenic compounds is prohibited in cosmetics, and the use of 57 types of substances and 66 types of preservatives is restricted. But it is these banned and restricted substances that can produce wonderful beauty and skin care effects. Don’t blindly pursue cosmetics that are expensive or advertise themselves as imported products with special effects. You should choose safe, reliable, mild, and effective products based on your skin type, and be sure to buy them in regular shopping malls.
3. Prevent allergies: Before choosing a new cosmetic that you are not familiar with or have never used, you should first do a skin test, such as trying it on a small area on the back of your hand to test whether you are allergic to it. It can only be used if you are allergic and have no reactions such as redness or itching. If you have the conditions, you can first buy a small package to try out the effect in a short period of time to determine whether it is suitable for your physique, hobbies, etc. For people with sensitive constitutions, you can also take small packages to the dermatology department of a regular hospital for an allergy test to accurately choose cosmetics that suit you. Even during daily use, if you find that cosmetics have adverse reactions on your skin, you should stop using them immediately.
4. Pay attention to the shelf life: Cosmetics contain fat, protein and other substances, which may easily deteriorate or be infected by bacteria over time. Therefore, cosmetics should be fresh, generally used within 3 to 6 months, and stored in a cool and dry place. In addition, many nutritional and medicinal plants have their biological active period, so the use of cosmetics should also be based on the expiration date and should be used within the best effectiveness period.
5. Pay attention to the details of use: Do not mix different brands, series, and types of cosmetics to avoid adverse reactions or bad odors. Cosmetics are generally only for external use, and do not use too much at one time. Avoid eating cosmetics into the body. It is best to wipe off lipstick before eating to avoid entering the body with food. Cosmetics on the skin should be washed off when sleeping, and do not fall asleep with cosmetics on. Pregnant and breastfeeding women and children should avoid using cosmetics. While choosing cosmetics that are suitable for you, it is best to pay attention to dietary nutrition supplements, consume more fresh vegetables and fruits, and delay skin aging through good living habits.
For some skin diseases, the use of cosmetics will not have a therapeutic effect, but you must go to a regular hospital for treatment.
