POLYURETHANE-11

Description

Polyurethane-11 is a synthetic polymer widely used in cosmetic and skincare formulations. This versatile ingredient functions primarily as a film-former and texture enhancer, providing a smooth, non-sticky feel to products. Its ability to create a flexible, breathable film on the skin makes it particularly valuable in long-wearing makeup formulations and protective skincare products.

The polymer is derived from the reaction of diisocyanates with polyols, resulting in a chain of repeating urethane units. This structure contributes to its excellent film-forming properties and resistance to water and oils. Polyurethane-11 is often employed in foundations, mascaras, and sunscreens to improve product adherence and longevity.

In skincare, Polyurethane-11 can help create barrier-like effects, potentially aiding in moisture retention and environmental protection. Its film-forming nature also assists in the even distribution of active ingredients across the skin's surface. The ingredient is generally well-tolerated and considered safe for use in cosmetic applications.

Formulators appreciate Polyurethane-11 for its compatibility with a wide range of other cosmetic ingredients and its stability across various pH levels. This versatility allows for its incorporation into diverse product types, from liquid foundations to cream-based skincare formulations.
