Bis-Octyldodecyl Dimer Dilinoleate/Propanediol Copolymer

Bis-Octyldodecyl Dimer Dilinoleate/Propanediol Copolymer is a synthetic polymer derived from linoleic acid (an omega-6 fatty acid) and propanediol. It functions as an emollient and skin conditioning agent, meaning it helps soften the skin surface and improve the appearance of texture.This ingredient is designed to be lightweight and spreadable, making it a practical choice for formulations where a richer feel would be impractical. It is not naturally derived, but rather engineered to deliver consistent performance across different product types.

This copolymer works by forming a light film on the skin surface, which helps to seal in moisture and smooth irregularities in the skin's texture. The linoleic acid component provides emollient properties, whilst the polymer structure ensures the ingredient spreads evenly and doesn't feel greasy.Unlike heavier occlusive ingredients, this material is designed to condition the skin without creating a barrier that might feel uncomfortable or trap excess oil, making it suitable for use in a range of product formulations.

This ingredient is typically used as part of a finished formulation rather than as a standalone product. Apply products containing this ingredient as directed on the label—usually once or twice daily. Since it is often found in creams, serums, and body care products, usage frequency will depend on the product type and your skin's individual needs.

Generally well-tolerated and considered safe for cosmetic use. Rare cases of sensitivity have been reported, so perform a patch test if you have very reactive skin.
