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
