POLYESTER-35

Description

Polyester-35 is a synthetic polymer used in cosmetic and personal care formulations as a film-forming agent and viscosity controller. This ingredient belongs to the family of polyesters, which are condensation polymers formed by the reaction of polyhydric alcohols and polycarboxylic acids. Polyester-35 is characterized by its high molecular weight and its ability to create a flexible, breathable film on the skin or hair surface.

In skincare products, Polyester-35 functions as an emollient and texture enhancer, providing a smooth, silky feel to formulations. It helps to improve the spreadability of products and can contribute to a more even application. The film-forming properties of Polyester-35 also assist in creating a barrier on the skin, which may help to reduce transepidermal water loss and protect against environmental stressors.

Polyester-35 is compatible with a wide range of cosmetic ingredients and is stable in various pH environments. It is commonly used in foundations, sunscreens, and other leave-on skincare products. While generally considered safe for topical use, as with any synthetic ingredient, some individuals may experience sensitivity. It is always recommended to perform a patch test before incorporating new products containing Polyester-35 into a skincare routine.
