C18-21 Alkane
What is C18-21 Alkane?
C18-21 Alkane consists of branched, saturated hydrocarbons with carbon chain lengths from 18 to 21 atoms. Typically derived through hydrogenation processes from renewable vegetable oils like coconut or palm kernel oil, it serves as a versatile ingredient in cosmetic products such as creams, serums, and foundations. In formulations, it acts primarily by dissolving other components, improving product spreadability, and imparting a non-greasy, velvety skin feel. Its low viscosity and controlled evaporation rate make it ideal for both oil- and water-based systems, enhancing the delivery of active ingredients while stabilizing emulsions. This emollient alternative to silicones or mineral oils supports clean beauty trends with its biodegradable profile and compatibility across various product textures, from lightweight lotions to rich balms.
