Polysilicone-13

What is Polysilicone-13?

Polysilicone-13 is a lab-synthesized copolymer blending siloxane chains with acrylic elements, creating a versatile silicone derivative. Primarily featured in hair care products such as conditioners, leave-in treatments, and styling sprays, it works by adhering to the hair surface and forming an invisible, elastic film. This film smooths rough cuticles, minimizes surface friction between strands, and shields against environmental stressors like humidity and UV exposure. Unlike heavier silicones, its structure allows for a non-greasy finish, promoting better comb-through and style retention. In formulations, it integrates easily into emulsions and gels, contributing to product stability and sensory appeal without altering viscosity significantly. Its inert nature ensures compatibility with a wide range of other cosmetic actives.
