Vaseline was first invented by the inventor Robert? The by-product extracted from petroleum by Robert Chessboro in 1859 was originally named "petroleumjelly", in which "petroleum" is petroleum and "jelly" is a colloidal substance, and was later named vaseline ['v? Gigi Lai: n]), and said in the American patent book of this product: "I, Robert? Chesberg invented a brand-new and very useful petrochemical product called vaseline. "
This word comes from the combination of the German word "wasser" and the Greek word "elaeon".
Vaseline is a transliteration of vaseline, which is an oily petroleum product. Mineral oil odor is allowed from white to yellow brown, but kerosene odor is not allowed. The impact point is about 37-54 degrees. It is refined from petroleum residue with sulfuric acid and clay, and can also be prepared from solid paraffin and mineral lubricating oil. Chemical composition of vaseline: long-chain alkanes.
The scientific name of vaseline is petrolatum. Its main raw material is wax paste extracted from the residual oil after atmospheric and vacuum distillation of crude oil. At the same time, it is necessary to mix different amounts of high and medium viscosity lubricating oil as needed. The yellow wax paste extracted from petroleum residue contains many impurities, which are not allowed to contain any substances harmful to human body or have peculiar smell, whether for medicinal or cosmetic purposes, and can only be used after deep refining and full removal. According to different requirements, it can be divided into ordinary vaseline, medical vaseline, cosmetic vaseline, industrial vaseline and capacitor vaseline.
Besides being used as lubricant, insulating agent, cosmetic, ointment, wetting and filling capacitor, it can also be used as antirust agent and waterproof agent. When making waterproof membrane, it is suggested to mix vaseline and tung oil and smear it on the surface of the object that needs waterproof. After drying, it is repeatedly brushed for 2-3 times to form a waterproof film.
[Edit this paragraph] Vaseline-Discovery
Vaseline was discovered as early as 1859, originally named "petroleumjelly", in which "petroleum" is oil and "jelly" is a colloidal substance, which was originally one of the by-products of oil exploitation. Later, a scientist named Robert Chessboro separated this white glue and named it "Vaseline".
If Robert Chessboro were alive, he would say, "I told you before, vaseline is a panacea."
Chesenberg is an American chemist who is good at extracting kerosene from whale fat. 1859, oil was discovered in Pennsylvania, USA, and Chesenburg was unemployed. Unwilling to fail, he ran to the Pennsylvania oilfield to see what the magic oil was all about. Careful, he soon discovered that oil field workers like to collect a black gel common on the edge of drilling platforms and apply it to injured skin, which is said to speed up wound healing. Chesterburg took a little back for testing, knowing that it was a kind of high molecular hydrocarbon, and there was a lot in the oil.
After the experiment, Chesenberg found a purification method, and finally got a colorless and transparent colloidal substance, which is odorless and tasteless, insoluble in water, and all common chemicals will not react with it. He deliberately cut a knife on his leg, and then put this thing on it, and the wound healed quickly.
1870, Chesenberg applied for a patent in the United States Patent Office and named it "Vaseline". He also set up a company and began to sell this magical gel to the American public. But no one believes that this thing is really effective, and the sales volume has never been opened.
In desperation, Cheson Beugras bought a car full of vaseline and became a "snake oil dealer" walking the streets. At that time, there were many vendors selling snake oil on the streets of the United States, much like the Jianghu artists selling "Hercules Pills" in old China. Chesenberg learned from the practice of snake oil dealers and personally practiced "hard training" everywhere, that is, he cut himself with a knife in front of everyone, or burned his skin, then confidently applied vaseline, and showed onlookers the healing of the wound injured a few days ago. This method is really effective. Vaseline quickly swept the United States, and Chesenburg made a fortune.
However, Chesenberg is not a doctor. He really believes that vaseline contains a mysterious substance that can cure all diseases. One year he got pleurisy, so he painted vaseline from head to toe. Later, when he got well, he believed that vaseline was a divine medicine and ate a spoonful of vaseline every day. After the news spread, Americans set off a vaseline fever and used it for everything.
Chesenberg lived to be 96 and died. He thinks vaseline helps him live longer.
[Edit this paragraph] Vaseline-Facts
In fact, scientists have studied vaseline carefully and found that there is nothing in vaseline except chemically inert hydrocarbons. However, it is not hydrophilic, and it can keep the skin moist, keep the skin tissue at the wound in the best condition, and accelerate the skin's own repair ability. In addition, vaseline has no bactericidal ability, it only blocks the contact between bacteria from the air and the skin, thus reducing the possibility of infection.
Many "curative effects" of vaseline are related to these two characteristics. For example, mothers like to apply a layer of vaseline on their babies' buttocks to avoid eczema caused by wet diapers touching the skin for a long time. People with nose bleeding can also apply vaseline to the inner wall of nostril to prevent further bleeding. Even patients with oral ulcers can dry the affected area with paper towels first, and then apply a layer of vaseline. Vaseline can prevent ulcers from contacting acidic substances in the mouth and accelerate the healing of ulcers.
Vaseline is very cheap,
