Product Description


Cholesteryl isostearate is a highly functional ester obtained from natural cholesterol and isostearic acid, a branched fatty acid. It is a versatile cosmetic ingredient that combines excellent emollient effects and skin affinity. Cholesterol is a component that is naturally present in the stratum corneum of the skin, and is characterized by its high biocompatibility and good compatibility with the skin. By combining it with isostearic acid, it achieves a smooth texture with excellent oxidation stability, improving the feel and functionality of cosmetics.

Main features:
・High skin affinity: The lipid-like structure contained in the stratum corneum achieves natural compatibility with the skin
・Excellent moisturizing and emollient effects: Forms a protective film on the skin surface and suppresses water evaporation
・High stability: The branched structure exhibits excellent stability against oxidation and heat
・Improved smooth texture: The gentle wax-like texture contributes to improving the texture of the product
・Assistance to emulsion stability: Effective for adjusting the texture and stabilizing emulsion in O/W emulsion systems

Applicable product examples:
Lip makeup products, after-bath treatment products, skin care products, sunscreen products, body care products, hand care products, etc.
