POLYESTER-26

Description

POLYESTER-26 is a synthetic polymer widely used in cosmetic and skincare formulations as a film-forming agent and viscosity controller. This versatile ingredient is composed of repeating ester units, providing unique properties that enhance product texture and performance.

In skincare applications, POLYESTER-26 forms a flexible, breathable film on the skin's surface, which helps to lock in moisture and protect against environmental stressors. This film-forming capability also contributes to the long-lasting effects of various cosmetic products, including foundations, sunscreens, and moisturizers.

As a viscosity controller, POLYESTER-26 helps stabilize emulsions and suspensions, ensuring consistent product texture and preventing separation of ingredients. Its ability to modify rheological properties allows formulators to create products with diverse consistencies, from light lotions to rich creams.

POLYESTER-26 is generally well-tolerated by most skin types and is considered non-comedogenic, making it suitable for use in products designed for acne-prone skin. Its low molecular weight allows for easy spreadability and quick absorption, contributing to a smooth, non-greasy feel upon application.

While POLYESTER-26 primarily serves functional purposes in formulations, it indirectly supports skin health by improving product efficacy and user experience.
