Also known as

Dilinoleic Acid Propanediol Copolymer dimer acid propanediol polyester dilinoleic acid 1,3-propanediol copolymer

Compatibility

Works well with:
cyclopentasiloxane dimethicone isododecane caprylic/capric triglyceride jojoba esters waxes

This oil-soluble polymer is well suited to anhydrous and low-water systems such as lip products, foundations, and skin-care oils. It is compatible with most silicones, esters, and waxes commonly used in color cosmetics and skin care. No notable aqueous incompatibilities are reported, though it is not designed for use in conventional water-continuous emulsions without appropriate formulation support.

Formulation notes

Dilinoleic Acid / Propanediol Copolymer is a polyester derived from the condensation of dimerized linoleic acid (a C36 dimer acid) with 1,3-propanediol. It functions primarily as a skin-conditioning emollient and film former, imparting a smooth, non-greasy skin feel and improving the wear and transfer-resistance of color cosmetic formulas. Its polymeric nature also contributes to viscosity modification and texture enhancement in anhydrous sticks, lipsticks, and long-wear foundations.
