Bis-Methoxypropylamido Isodocosane

What is Bis-Methoxypropylamido Isodocosane?

Bis-Methoxypropylamido Isodocosane is a synthetic emollient ingredient, chemically an amide derivative of branched-chain isodocosane (a C22 hydrocarbon) combined with methoxypropyl groups. Developed as a silicone alternative in cosmetics, it belongs to the category of conditioning agents used in skincare, haircare, and color cosmetics. In formulations, it works by spreading evenly on the skin's surface to create a thin lubricating film. This reduces friction between skin cells and product application tools, mimicking the slip and smoothness of silicones but with a drier, less occlusive finish. Its branched structure allows quick absorption and volatility, avoiding tackiness while enhancing product texture and spreadability. Primarily found in lotions, serums, and foundations, it supports even application and a non-greasy after-feel. (142 words)
