Lanolin, also known as sheep wool oil, is a refined fat extracted from sheep's wool. It mainly consists of various sterol compounds, free fatty acids, cholesterol, lanosterol, triterpenes, and fat-soluble vitamins. These components give lanolin various properties and benefits.



Firstly, lanolin has excellent emulsifying properties, meaning it can easily mix with water or other liquids to form a stable emulsion. This makes lanolin widely used in cosmetics and personal care products such as face creams, body lotions, and lip balms, as it helps products spread and absorb better on the skin.

Secondly, lanolin is highly moisturizing and can create a protective barrier on the skin, locking in moisture and preventing evaporation. This makes it an ideal ingredient for treating dry skin, chapped skin, and chilblains. Not only does it provide long-lasting hydration for the skin, but it also improves skin softness and smoothness.

Additionally, lanolin has preservative and soothing effects. It contains natural antibacterial components that can inhibit bacterial growth, thus preventing skin infections. At the same time, lanolin can alleviate skin inflammation and allergic reactions, reducing symptoms such as redness and itching.

In summary, lanolin is a natural, safe, and effective skincare ingredient widely used in various cosmetics and personal care products. It provides comprehensive moisturizing and nourishing effects for the skin, addressing issues like dryness and roughness, while also offering some preservative and soothing benefits. However, individual skin sensitivity to lanolin may vary, so it is recommended to perform a patch test before using products containing lanolin to ensure suitability for your skin type.
