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.
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]
In the Steglich esterification, alcohols, including even some tertiary alcohols, can be esterified using a carboxylic acid in the presence of DCC and a catalytic amount of DMAP. [ 7 ] In protein synthesis (such as Fmoc solid-state synthesizers ), the N-terminus is often used as the attachment site on which the amino acid monomers are added.
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 ...
Defatting is caused by the exposure of human skin to a chemical substance, including alcohols, detergents, chemical solvents and motor oil. Aliphatic compounds (commonly found in kerosene) cause defatting action, with lower-boiling point aliphatics having the greatest defatting action and therefore the most potential to cause dermatitis.
The mixture of nonylphenol isomers is a pale yellow liquid, although the pure compounds are colorless. The nonylphenols are moderately soluble in water [12] but soluble in alcohol. Nonylphenol arises from the environmental degradation of nonylphenol ethoxylates, which are the metabolites of commercial detergents called alkylphenol ethoxylates ...
Dodecanol / ˈ d oʊ ˈ d ɛ k ɑː n ɒ l /, or lauryl alcohol, is an organic compound produced industrially from palm kernel oil or coconut oil. It is a fatty alcohol . Sulfate esters of lauryl alcohol, especially sodium lauryl sulfate , are very widely used as surfactants .
