Composition
Hydrogenated lanolin is a complex mixture of fatty alcohols obtained by hydrogenating lanolin anhydrous.
By reacting with molecular hydrogen at high pressure and temperature in the presence of a solid-state catalyst such as raney nickel, lanolin esters are cracked and reduced to alcohols and hydrocarbons.
Depending on the exact reaction conditions, up to 90% of the yielded product consists of monohydric and dihydric fatty alcohols, with the rest made up of hydrocarbons (paraffins) and residual ester compounds.
Product features and applications
Hydrogenated lanolin keeps the emollient and adhering properties typical of refined wool wax products, but lacks their characteristic odour, colour and tackiness.

As a surfactant compound, it strongly reduces the interfacial tension of various oil-water systems. It's therefore used as a good emulsifying agent.
