Isopropyl rubbing alcohols contain from 50% to 99% by volume of isopropyl alcohol, the remainder consisting of water. Boiling points vary with the proportion of isopropyl alcohol from 80 to 83 °C (176 to 181 °F); likewise, freezing points vary from −32 to −50 °C (−26 to −58 °F). [6] Surgical spirit BP boils at 80 °C (176 °F). [7]
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.

These intermediates then react in an aldol condensation to the allyl aldehyde which the hydrogenation catalyst then reduces to the alcohol. [5] Guerbet Reaction Mechanism. The Cannizzaro reaction is a competing reaction when two aldehyde molecules react by disproportionation to form the corresponding alcohol and carboxylic acid.
Fischer esterification is an acyl substitution reaction based on the electrophilicity of the carbonyl carbon and the nucleophilicity of an alcohol. Carboxylic acids tend to be deprotonated by nucleophiles, which gives an unreactive carboxylate.
Jojoba esters are proper waxes; there is no triglyceride component of jojoba esters. Chemically, jojoba esters are a complex mixture of long chain fatty acids and fatty alcohols joined by an ester bond, resulting in a total length of 36 to 46 carbon atoms. [2]
