Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer
What is Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer?
Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer is a synthetic polymer created by copolymerizing polyglyceryl-3 stearate, isostearate, and dimer dilinoleate components. Polyglyceryl units derive from glycerol polymerized and esterified with stearic acid (straight-chain fatty acid), isostearic acid (branched fatty acid), and dimers from linoleic acid. Primarily used in color cosmetics like lipsticks, mascaras, eyeliners, and foundations, it serves as a film-former. It deposits a thin, elastic film on skin or hair, enhancing adhesion, flexibility, and resistance to moisture or friction. Additionally, it functions as a plasticizer to maintain film integrity without brittleness and aids in emulsifying oil-water phases for stable textures. The dimer's polymeric nature improves compatibility and spreadability, contributing to smooth, non-tacky finishes in long-wear formulations.
