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.
Useful properties of lanolin
Lanolin has a truly unique composition, representing a mixture of more than 15 thousand lanolin esters and 200 lanolin acids. The presence of multilamellar structures in it makes the product similar to the lipids that are in the skin of any person.
The main beneficial properties of the substance include:
- excellent nutrition and skin hydration;
- moisture retention in the skin;
- emulsifying properties;
- regulation of water-fat level;

Anhydrous lanolin in cosmetics
Lanolin is an ideal tool for dry and weathered skin, but it is also suitable for other skin types, including problem skin. Like any wax, it softens the skin and protects it from external influences. In addition to its basic properties, lanolin promotes the delivery of nutrients and active substances to the skin. This ability is associated with the presence of multilamellar structures related to skin lipids in the composition of lanolin.
The properties of lanolin are very wide:
- Softens the skin;
- Has an antibacterial effect;
- Thicken cosmetic formulas.
Anhydrous lanolin is an excellent emulsifier; with it, stable water-in-oil (W / O) emulsions are obtained, which have a light texture and are well absorbed. Even with prolonged storage, such formulas remain stable and do not burn out.
Lanolin does not irritate the skin, is well tolerated. Allergic reactions are very rare.
