What is Dilinoleic Acid?

Dilinoleic acid is a dicarboxylic fatty acid formed by dimerizing linoleic acid, an essential polyunsaturated omega-6 fatty acid sourced from plant oils like safflower or sunflower. This process creates a branched-chain molecule with emollient properties. In cosmetics, it falls under skin conditioning agents and emollients, commonly appearing in moisturizers, creams, and lotions. It functions by mimicking the skin's natural lipids, integrating into the intercellular matrix to bolster the barrier layer. This helps limit water evaporation while providing slip and smoothness to product textures, making skin feel supple without greasiness. Its non-pore-clogging nature suits various formulations, supporting overall skin comfort and flexibility.
