PPG-26/HDI COPOLYMER

Description

PPG-26/HDI Copolymer is a synthetic polymer used in various skincare and cosmetic formulations. This ingredient is primarily employed as a film-forming agent and viscosity controller, providing texture and stability to products. Composed of polypropylene glycol (PPG) and hexamethylene diisocyanate (HDI), this copolymer creates a flexible, water-resistant barrier on the skin's surface.

In skincare applications, PPG-26/HDI Copolymer enhances product performance by improving spreadability and creating a smooth, even finish. It helps to lock in moisture and other beneficial ingredients, potentially prolonging their effects on the skin. The film-forming properties also contribute to the longevity of makeup and sunscreen products, improving their wear time and resistance to water and sweat.

While generally considered safe for topical use, some individuals may experience sensitivity to isocyanate-based compounds. As with any cosmetic ingredient, patch testing is recommended for those with sensitive skin or a history of allergic reactions. PPG-26/HDI Copolymer is typically used in low concentrations in formulations, ranging from 0.1% to 5%, depending on the product type and desired effects.
