TEREPHTHALIC ACID/ISOPHTHALIC ACID/SODIUM ISOPHTHALIC ACID SULFONATE/GLYCOL COPOLYMER

Description

Terephthalic Acid/Isophthalic Acid/Sodium Isophthalic Acid Sulfonate/Glycol Copolymer is a complex synthetic ingredient utilized in various skincare and cosmetic formulations. This copolymer is primarily employed as a film-forming agent and conditioning polymer. Its unique chemical structure, combining different acid components with glycol, allows it to create a thin, flexible film on the skin or hair surface.

In skincare applications, this copolymer enhances product texture and improves the adherence of active ingredients to the skin. It contributes to the formation of a protective barrier, which can help reduce transepidermal water loss and maintain skin hydration. The presence of sodium isophthalic acid sulfonate in the polymer chain imparts water-solubility and improves its compatibility with other ingredients in aqueous formulations.

This ingredient is particularly beneficial in long-wearing makeup products, sunscreens, and moisturizers. It aids in creating smooth, even applications and can improve the longevity of the product on the skin. The copolymer is generally well-tolerated by most skin types and is considered safe for use in cosmetic formulations when used at appropriate concentrations as determined by regulatory guidelines.
