Bis-Octyldodecyl Dimer Dilinoleate/Propanediol Copolymer
What is Bis-Octyldodecyl Dimer Dilinoleate/Propanediol Copolymer?
Bis-Octyldodecyl Dimer Dilinoleate/Propanediol Copolymer is a high-molecular-weight synthetic polymer created by copolymerizing the bis-octyldodecyl ester of dimer dilinoleic acid with propanediol. Dimer dilinoleic acid originates from the dimerization of linoleic acid, an unsaturated fatty acid sourced from vegetable oils such as safflower or sunflower. Octyldodecanol is a branched-chain fatty alcohol, and propanediol serves as a linking diol, often derived from corn-based glucose or petroleum. Primarily used in color cosmetics like lipsticks, lip glosses, and mascaras, it functions as a film-forming agent. It deposits a thin, elastic film on the skin or lips that enhances product adhesion, imparts flexibility to prevent cracking, improves wear resistance, and delivers mild emollient effects for a smooth, non-tacky feel. This makes it ideal for long-wear formulations without heaviness.
