Oleyl alcohol / ˈ oʊ l i ˌ ɪ l, ˈ oʊ l i əl /, [1] or cis-9-octadecen-1-ol, is an unsaturated fatty alcohol with the molecular formula C 18 H 36 O or the condensed structural formula CH 3 (CH 2) 7 −CH=CH−(CH 2) 8 OH. It is a colorless oil, mainly used in cosmetics.
An example of an ester formation is the substitution reaction between a carboxylic acid (R−C(=O)−OH) and an alcohol (R'OH), forming an ester (R−C(=O)−O−R'), where R and R′ are organyl groups, or H in the case of esters of formic acid.
In chemistry, an alcohol (from Arabic al-kuḥl 'the kohl'), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [3] [4] Alcohols range from the simple, like methanol and ethanol, to complex, like sugar alcohols and cholesterol. The presence of an OH group strongly ...
Arachidyl alcohol (icosan-1-ol), is a waxy substance used as an emollient in cosmetics. It is a straight-chain fatty alcohol with 20 carbon atoms, typically obtained via the hydrogenation of arachidic acid or arachidonic acid, both of which are present in peanut oil. Its name is derived from that of the peanut plant (Latin: arachis).
Side effects of alcohols applied to the skin include skin irritation. [2] Care should be taken with electrocautery, as ethanol is flammable. [1] Types of alcohol used include ethanol, denatured ethanol, 1-propanol, and isopropyl alcohol. [6] [7] Alcohols are effective against a range of microorganisms, though they do not inactivate spores. [7]
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
Benzyl alcohol is used effectively for treating lice infestations as the active ingredient in lotion shampoo with 5% benzyl alcohol. [13] Benzyl alcohol is an ingredient used in the manufacture of soaps, topical creams, skin lotions, shampoos, and facial cleansers and is popular due to its anti-bacterial and anti-fungal properties.
Stearyl alcohol, or 1-octadecanol, is an organic compound classified as a saturated fatty alcohol with the formula CH 3 (CH 2) 16 CH 2 OH. It takes the form of white granules or flakes, which are insoluble in water. It has a wide range of uses as an ingredient in lubricants, resins, perfumes, and cosmetics.
