Fatty alcohols, derived from natural fats and oils,
are high molecular straight chain primary
alcohols. They include lauryl (C12), MyrIstyl
(C14), Cetyl ( or palmityl: C16), stearyl (C18),
Oleyl (C18, unsaturated), and Linoleyl (C18,
polyunsaturated) alcohols. There are synthetic
fatty alcohols equivalent physically and
chemically to natural alcohols obtained from
oleochemical sources such as coconut and palm
kernel oil. Fatty alcohols are emulsifiers and
emollients to make skin smoother and prevent
moisture loss. Identical fatty esters are used to
improve rub-out of formulas and to control
viscosity and dispersion characteristics in
cosmetics, personal care products and
pharmaceutical ingredients. As chemical
intermediates, the primary use of fatty alcohols
are as raw material for the production of fatty
sulfate salts and alcohol ethoxylates for foaming
and cleaning purposes in the field of detergent
industry. Chemical reactions of primary alcohols
include esterifications, ethoxylation, sulfation,
oxidation and many other reactions.
