POLYESTER-3

Description

Polyester-3 is a synthetic polymer used in cosmetic and skincare formulations as a film-forming agent and viscosity controller. This ingredient belongs to the family of polyesters, which are condensation polymers formed from polyhydric alcohols and polybasic acids. Polyester-3 is particularly valued for its ability to create a smooth, even film on the skin's surface, providing a lightweight and non-greasy feel.

In skincare products, Polyester-3 functions as an emollient and texture enhancer, contributing to improved spreadability and a silky finish. It helps to stabilize formulations and can act as a binder for other ingredients. The film-forming properties of Polyester-3 can aid in the even distribution of active ingredients across the skin and may offer some degree of water resistance to formulations.

This ingredient is generally well-tolerated by most skin types and is considered safe for use in cosmetic applications. Polyester-3 is often found in foundations, sunscreens, and other leave-on skincare products where a smooth application and long-lasting wear are desired. Its versatility makes it a popular choice among formulators seeking to create elegant, high-performance skincare and cosmetic products.
