POLYESTER-11

Description

Polyester-11 is a synthetic polymer widely used in cosmetic and personal care formulations. This versatile ingredient functions primarily as a film-forming agent and texture enhancer, contributing to the overall sensory experience and performance of skincare and makeup products.

Chemically, Polyester-11 is a copolymer of adipic acid and neopentyl glycol. Its structure allows it to form a flexible, breathable film on the skin's surface, which can help improve the longevity of cosmetic applications and provide a smooth, even finish.

In skincare formulations, Polyester-11 aids in creating lightweight, non-greasy textures that spread easily and absorb quickly. It can enhance the substantivity of active ingredients, potentially improving their efficacy. The film-forming properties of Polyester-11 also contribute to water resistance in sunscreens and long-wear makeup products.

This ingredient is generally well-tolerated by most skin types and is considered safe for use in cosmetics. However, as with any synthetic polymer, individuals with sensitive skin should perform patch tests before widespread use. Polyester-11's ability to improve product texture and performance makes it a valuable component in modern cosmetic formulations.
