POLYESTER-7

Description

Polyester-7 is a synthetic polymer utilized in various cosmetic and personal care formulations. This ingredient functions primarily as a film-forming agent and viscosity controller, contributing to the texture and stability of products. Derived from polymerization of ester monomers, Polyester-7 creates a flexible, breathable film on the skin or hair surface.

In skincare applications, Polyester-7 enhances the spreadability of products and helps to maintain a smooth, even application. It can improve the water resistance of sunscreens and makeup, potentially extending wear time. In hair care, it aids in creating lightweight styling products that offer hold without stiffness.

Polyester-7 is generally considered safe for topical use and is compatible with a wide range of other cosmetic ingredients. It's particularly useful in formulations requiring a non-tacky feel and improved product adherence to the skin or hair. While not an active ingredient in terms of skin benefits, its functional properties make it valuable in enhancing product performance and user experience.

Formulators should consider Polyester-7 when developing long-wearing makeup, water-resistant sunscreens, or hair styling products that require a flexible hold. Its ability to form films without excessive tackiness makes it a versatile ingredient in modern cosmetic formulations.
