Sorbitol/Sebacic Acid Copolymer Behenate
What is Sorbitol/Sebacic Acid Copolymer Behenate?
Sorbitol/Sebacic Acid Copolymer Behenate is a synthetic polyester formed by copolymerizing sorbitol, a sugar-derived polyol, with sebacic acid, a dicarboxylic acid from castor oil, and terminating with behenic acid, a long-chain saturated fatty acid. This creates a branched polymer structure. Primarily used in color cosmetics like lipsticks, glosses, mascaras, and eyeliners, it functions as a film former and viscosity controller. Upon application, it dries to form a flexible, adhesive film that binds pigments and waxes to skin or lashes, enhancing durability, reducing transfer, and providing a silky feel without stickiness. Its hydrophobic nature repels water and oils, supporting smudge-resistant formulas while maintaining flexibility to avoid cracking.
Benefits
Forms durable films for extended makeup wear
Enhances smooth, even application and texture
Supports non-comedogenic properties for clearer skin feel
