Description of lanolin anhydrous
Lanolin is a viscous substance from yellow to cream color, obtained from wax, which is formed on the wool of sheep from the secretion of the sebaceous glands. It has a slight specific smell, but when added, cosmetics do not violate the perfume composition, it becomes almost invisible.
In pharmacies and specialty stores you can find an aqueous solution of lanolin and anhydrous lanolin. The latter is characterized in that it can bind water molecules. It is used in cosmetic formulas.
Anhydrous lanolin in cosmetics is, in fact, an oil extracted from animal fats. It contains cholesterol, which is necessary for skin to moisturize, as well as cholesterol and wax esters. It is believed that a quality product should contain at least 50% non-saponifiable substances, in which the proportion of cholesterol is 30%. In practice, the chemical composition of lanolin may vary, depending on the breed of sheep and the conditions of their maintenance.
