  Fatty alcohol - Wikipedia, the free encyclopedia
Fatty alcohols are aliphatic alcohols derived from natural fats and oils.
Fatty alcohols are a common component of waxes, mostly as esters with fatty acids but also as alcohols themselves.
Behenyl alcohol, lignoceryl alcohol, ceryl alcohol, 1-heptacosanol, montanyl alcohol, 1-nonacosanol, myricyl alcohol, 1-dotriacontanol, and geddyl alcohol are together classified as policosanol, with montanyl alcohol and myricyl alcohol being the most abundant.

 Patent 6,087,403
The fatty alcohols of formula ROH having 14 to 22 carbon atoms and particularly the mixtures of hexadecanol and octadecanol are particularly preferred.
Because of their effectiveness and ease of production, compositions containing 40 to 60% by weight of fatty alcohols based on the total weight of the composition and preferably 52 to 57% of fatty alcohol, the remainder consisting of polyglycosides, apart from any impurities, are most particularly preferred.
The compositions based on polyglycosides and fatty alcohols according to the invention may also be used in formulations in which finely divided solids have to be kept suspended in water, such as formulations of agrochemical substances (herbicides, insecticides, fungicides) known under the generic name of "concentrated suspensions".

In such alcohols at least 30% of the alcohol of each specific chain length is desirably linear and the branching preferably comprises about 50% of methyl groups with smaller amounts of ethyl, propyl and butyl groups.
In effect, the alcohol acts as the solvent for the initial part of the reaction and the alkoxide of the fatty alcohol polyethoxylated is fluid and acts as a solvent for the last part of the reaction.
Both were derived from fatty alcohols containing approximately the same alkyl chain lengths and distributions and the polyethoxy portions of the compounds had the same average chain length, but the samples differed in distribution of the various polyethoxy homologs.
