Cholesteryl Nonanoate
What is Cholesteryl Nonanoate?
Cholesteryl Nonanoate is a synthetic ester formed from cholesterol and nonanoic acid, engineered to resemble lipids in the skin's stratum corneum. Primarily used in moisturizers, creams, and serums as an emollient, it creates liquid crystal phases that align with the skin's barrier structure. This allows it to spread evenly, fill surface irregularities, and provide a silky feel during application. In formulations, it enhances texture by improving slip and cohesion, often in anhydrous or liposomal systems. Its biomimetic properties support skin's lipid organization without penetrating deeply, focusing on surface conditioning for daily care products.
