Lanolin alcohols are also known as wool fat alcohols and are a mixture of cholesterol, dihydrocholesterol and lanosterol. Preferred polyethers for use according to the invention are cholesteryl polyoxyethylene ethers, e.g. polyethers of the above formula, wherein n=2 and RO is a cholesteryl ...
Textile materials are treated with an aqueous emulsion containing lanolin, a cationic emulsifying agent and a non-ionic emulsifying agent, the emulsion being stable in the absence of the textile material, and deposition of lanolin upon the textile material is caused by the addition of an alkali ...
Using fractions of ceramide-rich lanolin for skin treatment, and compositions containing them. The discovery that lanolin contains ceramides the, albeit at low rates, has yielded fractions of lanolin with relatively high content of natural ceramides from wool. Such lanolin fractions show a moisturizing...

By combining effective recycling of lanolin and treatment of pollutants, the method can solve the problems of recycling of resources and harmless treatment of wastes in the treatment process of wastewater resulting from wool-washing.doi:WO2013159534 A1WANG, Shuzhong...
The raw wool treating supercritical CO2 process includes the following steps: 1. depurating raw wool; 2. extracting depurated raw wool with supercritical CO2 to obtain lanolin and degreased wool. The supercritical CO2 process has the conditions, including extraction pressure 30-40 MPa, extraction ...
