Bis-Hydroxylauryl Dimethicone/Ipdi Copolymer

What is Bis-Hydroxylauryl Dimethicone/Ipdi Copolymer?

Bis-Hydroxylauryl Dimethicone/IPDI Copolymer is a synthetic polymer derived from silicone chemistry, specifically a copolymer of bis-hydroxylauryl dimethicone crosslinked with isophorone diisocyanate (IPDI). This creates a flexible, elastomeric structure commonly incorporated into color cosmetics such as lip products, mascaras, and foundations, as well as select skincare items. In formulations, it functions by depositing a thin, continuous film upon application, which enhances adhesion, resists water and transfer, and provides a smooth, non-tacky finish. Its humectant nature draws moisture to the skin surface, supporting hydration during wear. Additionally, it influences product viscosity for better flow and stability, while conditioning the skin to feel softer and more pliable without greasiness. This ingredient excels in delivering durable performance in makeup that withstands daily activities.
