GLYCERIN/PHTHALIC ACID COPOLYMER

Description

Glycerin/Phthalic Acid Copolymer is a synthetic ingredient widely used in skincare and cosmetic formulations. This copolymer is created through the condensation reaction of glycerin and phthalic acid, resulting in a unique molecular structure that combines hydrophilic and hydrophobic properties. Its primary function is as a film-forming agent, providing a protective barrier on the skin's surface.

The copolymer's ability to form a flexible, breathable film helps to lock in moisture and protect the skin from environmental stressors. This property makes it particularly useful in products designed for dry or sensitive skin. Additionally, it acts as an emollient, improving the skin's texture and enhancing its smoothness.

Glycerin/Phthalic Acid Copolymer also serves as a viscosity controller, helping to stabilize formulations and improve their texture. It is compatible with a wide range of cosmetic ingredients, making it versatile for use in various product types, including moisturizers, serums, and sunscreens.

While generally considered safe for topical use, it's important to note that some individuals may be sensitive to phthalic acid derivatives. As with any skincare ingredient, patch testing is recommended for those with sensitive skin or a history of allergic reactions.
