Linalool has a strong ability to mask the disgusting odor of sulfide hydrocarbons, garlic preparations and polysulfides.
In addition, linalool is the main component of these deodorant formulations, which is used to deodorize excreta, especially human and livestock excreta. Experiments show that using 0. Adding linalool with the concentration of 1% to the medium containing 2% sucrose, 100% can inhibit Streptococcus mutans from converting sucrose into grape polysaccharide, thus preventing the formation of dental plaque.
It is also reported that adding terpenoid alcohol organic compounds to tooth powder can keep glucanase in tooth powder stable and effectively prevent dental plaque. (1) on mosquitoes and flies;
Liquid medicine containing 2% linalyl acetate ozonide and 98% mineral oil was applied to the skin to repel mosquitoes and flies. Can be used as repellent for cockroaches, ants, lice, etc. It can also be used in textile materials to drive away pests.
It is also found that foods containing linalool can significantly reduce the foraging and oviposition of houseflies, because maggots can only develop on organisms rich in microorganisms, so pregnant females will detect and avoid laying eggs on linalool substances with strong antibacterial effect.
(2) Acaricide:
Linalool has acaricidal ability, which is effective for both larvae and adults. It is reported that the anti-mite activity test was carried out on a stored food mite, tyrophagus longipes. It is also reported that the formula composed of more than 20 kinds of volatile oil components such as linalool has satisfactory effects on dust mites and edible tyrophagus. Another characteristic of linalool is that it can be biotransformed under the catalysis of microorganisms. For example, under the catalysis of Aspergillus Niger, (R)-(-)- linalool will undergo biotransformation to produce trans furan and trans pyran linalool oxide.
2-5 kinds of pigments with high catalytic activity can catalyze the decomposition of linalool, and the decomposition products vary with the properties of pigments. It was identified that the decomposition products included dehydrolinalool, such as myrcene, perillene and perillene, and cyclic products, such as limonene, terpinene and α-terpinene. Among these pigments, one with high activity will produce cymene, which is the main reason for the bad smell of some cosmetics containing pigments. Judging from the words of the perfumers I have contacted, I don't know enough about this feature.
Dehydrolinalool is due to the formation of carbon ion intermediate at the acid site of pigment and cyclization product after allyl rearrangement. Terpenes such as linalool have good antibacterial activity against Escherichia coli, Proteus, Enterobacteriaceae, Staphylococcus, Saccharomyces cerevisiae, Leucoccosis, Aspergillus niger and agar.
It is reported that the antibacterial effect of linalool is five times that of phenol and similar to that of citronellol. It is used to treat acne because it has antibacterial activity against Propionibacterium. Linalool has a synergistic effect on the hammer-resistant mutant of alanine.
Animal experiments show that feeding one milligram of linalool to chickens infected with ES4 virus every day can prolong their life span by 50-80%.
It is reported that ozone (O3) passes through terpenes to produce terpene ozone, which can be used to treat inflammation, tumors, microbial infections and burns.
Ozone was made into linalool odorous oxide by linalool, which showed inhibitory activity against Escherichia coli in test tubes. Foreign folks have used volatile oil or plants containing linalool as hypnotics and sedatives since ancient times.
However, among terpineol, only α-terpineol of linalool and tertiary methanol has obvious sedative effect. In order to evaluate the direct psychopharmacological effects of linalool on experimental mice, the results showed that the central nervous system, including sleep, anticonvulsant and hypothermia, was enhanced with the increase of dose. (RS)-(+) linalool, (R)-(-) linalool and (S)-(+) linalool are inhaled into human body. Under the conditions of mental work, physical exercise and interharmonic signals, the frontal lobe EEG was recorded and scored, and the physiological response was measured. The results show that levorotatory and racemic forms have obvious sedative effects, while dextrorotatory forms have the opposite effect. (1) Improve fat quality:
It is reported in Japan that the oil containing a small amount of linalool and linalyl acetate can be heated at 100℃ for a long time, and its smell is better than that of the control group. If some derivatives of linalool are used in combination with vitamin E, it has obvious synergistic antioxidant effect on lard, palm oil and other oils.
(2) stable foam energy:
Adding a small amount of linalool to the spray-type water-based cleaning agent containing nonionic or anionic surfactants can effectively increase the stability of foam.
(3) Tea-based aromatic beverages:
According to data analysis, the relative content of linalool in the aroma components of tea (green tea) is 19.88%, which is one of the most important aroma components. According to the patent introduction, 250g tea was extracted with water, diluted to 10L, and a small amount of spices such as methyl anisate and linalool were added. After evaluation, the fragrance of tea leaves is stronger than that of untreated tea.
(4) mildew inhibitor:
Linalool and its acetate can inhibit the growth of fungal spores or mycelium, and can be used as fungicides for fungal infections or other antifungal materials.
(5) Animal repellent:
The essence made of linalool, geraniol and phenylethanol has a good repellent effect on birds such as sparrows, crows and pigeons.
(6) Bad odor masking agent for daily chemical products:
Adding 1-5% linalool and its esters to kerosene can be used as a deodorant for burning kerosene.
Adding 0.0 1-2% linalool to detergent containing protease can mask the bad smell of enzyme preparation. Similarly, when used in bleaching agents containing enzymes, bleached textiles can have good fragrance.
Adding terpenoid essential oils such as linalool to textile softener can also achieve the purpose of covering up odor.
Adding 1% linalool or linalool essential oil to the liquid medicine of permanent curling agent can remove the bad smell left on hair by curling agent.
