C12-13 Alkyl Lactate

What is C12-13 Alkyl Lactate?

C12-13 Alkyl Lactate is a synthetic ester formed by combining lactic acid, a simple alpha-hydroxy acid produced via fermentation, with a blend of straight-chain alcohols containing 12 to 13 carbon atoms. This creates a lightweight, oil-like compound commonly incorporated into skincare products such as moisturizers, lotions, and serums within the emollient category. It functions by forming a thin lubricating film on the skin's surface, which reduces friction, enhances product glide during application, and mimics natural skin lipids to promote a supple feel. In formulations, it aids in dispersing other ingredients evenly and contributes to a non-greasy finish, making it suitable for daily use in various textures from creams to gels. Its structure allows penetration into the upper skin layers without heaviness, supporting overall product performance.
