What is lanolin primarily used for in cosmetic products?

Lanolin is primarily recognized for its exceptional moisturization properties, making it a popular ingredient in cosmetic products. Derived from sheep's wool, lanolin acts as an emollient, which means it has the ability to soften and hydrate the skin. Its composition includes natural fats that mimic the skin's own oils, allowing it to form a barrier that locks in moisture and prevents dehydration. This characteristic makes lanolin particularly beneficial in products designed for dry skin, lip balms, creams, and lotions.

While other ingredients in cosmetics serve different purposes such as adding fragrance, color, or preserving the product, lanolin's primary function revolves around enhancing moisture retention and ensuring the skin remains hydrated and supple. Thus, its role in moisturization is crucial and distinguishes it from other functional ingredients in the cosmetic industry.
