Capryloyl Glycerin/Sebacic Acid Copolymer

What is Capryloyl Glycerin/Sebacic Acid Copolymer?

Capryloyl Glycerin/Sebacic Acid Copolymer is a synthetic polyester polymer formed by combining capryloyl glycerin, an ester derived from caprylic acid and glycerin, with sebacic acid, a dicarboxylic acid often sourced from castor oil. Primarily used in color cosmetics like lip products, mascaras, and long-wear foundations, it functions as a film former. Upon application, it dries to create a thin, elastic, transparent film that adheres to the skin or hair surface. This film improves product longevity, resists water and transfer, and provides a smooth, non-sticky finish without compromising breathability. Its lightweight nature makes it suitable for formulations seeking extended wear properties while maintaining comfort.
