POLYESTER-10

Description

Polyester-10 is a synthetic polymer widely used in cosmetic and personal care formulations. This versatile ingredient functions primarily as a film-forming agent and emulsion stabilizer. Its chemical structure consists of repeating units of polyethylene terephthalate (PET), modified to enhance its solubility and compatibility with various cosmetic ingredients.

In skincare products, Polyester-10 creates a thin, flexible film on the skin's surface, which helps to improve the texture and feel of formulations. This film-forming property also aids in the even distribution of active ingredients and can contribute to increased product longevity on the skin. As an emulsion stabilizer, it helps maintain the integrity of cosmetic formulations by preventing the separation of oil and water phases.

Polyester-10 is particularly valued for its ability to enhance the water resistance of sunscreens and other topical products, potentially improving their efficacy and durability. It is generally considered safe for use in cosmetics and is compatible with a wide range of other ingredients. However, as with any synthetic polymer, some individuals may experience sensitivity, so patch testing is recommended for those with reactive skin.
