Dicaprylyl Maleate

What is Dicaprylyl Maleate?

Dicaprylyl Maleate is a diester formed from maleic acid and caprylyl alcohol (a C8 fatty alcohol derived from natural sources but synthetically processed). It belongs to the category of emollient esters commonly used in anhydrous formulations like sunscreens, lip products, and oil-based serums. In cosmetics, it functions by providing a non-greasy slip on the skin surface, mimicking natural sebum to smooth roughness and reduce friction during application. As a solvent, it effectively dissolves lipophilic actives such as UV filters and fragrances, ensuring even distribution and stability. Its low viscosity helps control product spreadability and evaporation, while pairing well with occlusives to support barrier function without heaviness.
