SOLUBILITY: practically insoluble in water, slightly soluble in boiling anhydrous ethanol.
CHEMISTRY 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 chemicallyas 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.
