APPEARANCE:LANOLIN is a pale yellow, tenacious, unctuous substance obtained from the wool of
sheep，having a faint but characteristic odor. When melted, it is a clear or almost clear yellow
liquid.SOLUBILITY:practically insoluble in water, slightly soluble in boiling anhydrous ethanol.
Lanolin is also called wool fat, wool wax or wool grease. As lanolin lacks glycerides
(glycerol esters), it is not a true fat.Lanolin primarily consists of sterol esters instead. Lanolin
is classified chemically as a wax, being a complex mixture of naturally occurring esters
and poly-esters of 33 high molecular weight alcohols (principally sterols) and 36 fatty acids.
It is 98% ester minimum, of which the fatty alcohols and fatty acids comprise an
approximately 50/50 ratio.
TYPICAL COMPOSITION OF LANOLIN
Esters of sterols and triterpene alcohols
