Composition and Description

ISOPROPYL LANOLATE is the solid high molecular weight fraction of the isopropyl lanolate, which is produced by esterification of natural lanolin fatty acids with isopropyl alcohol. The solid content is separated from the rest of the ester mixture by fractional distillation under high vacuum.

Features

ISOPROPYL LANOLATE has excellent characteristics in terms of colour and odour. It has a high homogeneity because most of the liquid components have been removed. It is non-greasy and gives the skin a soft and smooth feeling. Although it is not a strong W/O emulsifier, it has good compatibility with emulsions of this type, especially when a small amount of cetyl alcohol is added.

Applications

When colour and odour is of importance consideration for hand-, sport- and cleaning creams formulation, ISOPROPYL LANOLATE is the right choice of lanolin derivative to achieve an emollient effect or to reduce the occlusive characteristics and stickiness of hydrocarbon bases. It is an excellent lubricant in lipsticks to reduce the frictional resistance during application and helps to achieve a glossy film. Furthermore, it can be used as binder in compact powders and as super-fattening agent for luxury soaps.

Dermatology

Patch tests with ISOPROPYL LANOLATE on healthy subjects did not show any harmful skin reactions. No adverse reaction was reported for the past 20 years of production and application of ISOPROPYL LANOLATE.

Processing

ISOPROPYL LANOLATE is safe and easy to use. The melting is best done in a jacketed vessel, but the material is soft enough to be pumped without being heated. It should not be heated above 80 °C for an extended time. Cool storage is recommended. When stored under certain circumstances, light syneresis might occur because some esters of low molecular weight separate and form a free liquid phase. Homogeneity, however, can be easily restored by melting the material. ISOPROPYL LANOLATE can be stored under normal conditions for at least 2 years.

Solubility at room temperature

Water: none; acetone: partially soluble; ethanol, anhydrous: partially soluble
