Composition and Description

HYDROGENATED LANOLIN is obtained from purified lanolin by direct hydrogenation at high pressure and temperature. Both the free acids and the esters of the wax are reduced to alcohols, and the double bonds are saturated. HYDROGENATED LANOLIN is composed of about 48%–62% dihydroxy and 18%–30% monohydroxy alcohols, as well as 10%–15% hydrocarbons and 2%–4% esters.

Features

HYDROGENATED LANOLIN is characterized by a particularly bright colour and a neutral odour. Moreover, it is less tacky than conventional lanolin, but still has comparable emollient properties. Since HYDROGENATED LANOLIN consists almost exclusively of alcohols, it is very similar in its properties to lanolin alcohols and can also be used as a W/O emulsifier.

Applications

The use of this product is recommended in cosmetic formulations where colour and odour are important. In general, the use of 2%–10% as base, W/O emulsifier, emollient or antistatic agent in ointments, creams, lotions, as well as in decorative cosmetics and hair and eye care products is recommended.

Dermatology

HYDROGENATED LANOLIN has emollient properties similar to lanolin. It is used in many pharmaceutical and cosmetic products. In only a very few cases has an allergic reaction been observed. The oral LD50 was reported in various studies to be above at least 5 g/kg, and up to above 64 ml/kg. In a human study, no irritating effect on the skin was observed.

Processing

HYDROGENATED LANOLIN is easy to use and should be processed in its melted form. It is safe, easy to melt and has relatively low volatility. Heat sterilization is possible. HYDROGENATED LANOLIN is more stable than conventional lanolin, but should be kept cool and protected from light. Since it has no double bonds, it has low susceptibility to oxidation.

Solubility at room temperature
