POLYESTER-37

Description

Polyester-37 is a synthetic polymer used in various cosmetic and skincare formulations. This ingredient functions primarily as a film-forming agent and emulsion stabilizer, providing texture and enhancing the overall performance of products. Polyester-37 is derived from the polymerization of specific esters, resulting in a long-chain molecule with unique properties beneficial for skincare applications.

In formulations, Polyester-37 creates a thin, flexible film on the skin's surface, which helps to improve product adherence and longevity. This film-forming ability is particularly useful in makeup products, sunscreens, and long-wear skincare formulas. Additionally, Polyester-37 contributes to the stability of emulsions, preventing separation of oil and water phases in creams and lotions.

The ingredient is known for its ability to enhance the sensory attributes of skincare products, imparting a smooth, silky feel upon application. It also aids in reducing the tacky or greasy sensation often associated with certain formulations. Polyester-37 is generally well-tolerated by most skin types and is considered safe for use in cosmetic products when used at appropriate concentrations.
