Ethylenediamine/Stearyl Dimer Dilinoleate Copolymer

What is Ethylenediamine/Stearyl Dimer Dilinoleate Copolymer?

Ethylenediamine/Stearyl Dimer Dilinoleate Copolymer is a synthetic polymer formed by combining ethylenediamine with stearyl dimer dilinoleate, a derivative of dimerized linoleic acid from plant oils and stearyl alcohol. Commonly found in lip products, oral care items like toothpastes and mouthwashes, and skin formulations, it functions primarily as a film-former. This creates a flexible, protective layer on skin, lips, or oral surfaces to lock in moisture and improve wear. It also adjusts product thickness for smooth application, better suspension of particles, and enhanced stability, making formulations easier to use and more effective in delivering active components.
