BIS-POLY(1,4-BUTANEDIOL)-14/HDI COPOLYMER

Description

Bis-Poly(1,4-Butanediol)-14/HDI Copolymer is a synthetic polymer used in advanced skincare and cosmetic formulations. This ingredient functions primarily as a film-forming agent and texture enhancer. Its structure is derived from the reaction between 1,4-butanediol and hexamethylene diisocyanate (HDI), resulting in a unique copolymer with both flexibility and durability.

In skincare applications, Bis-Poly(1,4-Butanediol)-14/HDI Copolymer creates a breathable, protective barrier on the skin's surface. This film helps to lock in moisture and protect against environmental stressors. The polymer's molecular structure allows for even distribution across the skin, promoting a smooth, uniform application of products.

The ingredient is particularly valuable in long-wear cosmetic formulations, such as foundations and concealers, where it enhances product adherence and longevity. It also contributes to improved water resistance in sunscreens and other protective skincare products. Due to its low molecular weight, this copolymer is less likely to cause pore blockage compared to heavier film-formers.

While generally well-tolerated, individuals with sensitive skin or a history of reactions to isocyanate compounds should exercise caution when using products containing this ingredient.
