Cholesteryl Hydroxystearate is a chemical that is also known as Cholest-5-en-3-ol, 12-hydroxyoctadecanoate. This substance is an ester derivative of cholesterol and hydroxystearic acid. Cholesteryl Hydroxystearate is very resistant to water, which means that it does not dissolve in water. It is a white to slightly yellowish crystalline substance that is indigestible in the body. Barberá et al. carried out a functional analysis of a tear in the earth containing Cholesteryl Hydroxystearate and found that this substance acts as a singlet oxygen irritant.

Cholesteryl Hydroxystearate is used in a variety of products, including cosmetic and personal skin care products. This substance effectively improves the condition of the skin, especially drier skin, because it is able to form a protective barrier that prevents moisture loss from the skin. Cholesteryl Hydroxystearate is also included in some sunscreens because it helps protect the skin from the sun. It is an important ingredient in a variety of products because it provides better product durability and stability. However, despite its wide applicability and usefulness, it can cause allergic reactions in some people and should therefore be used with caution.
