POLYURETHANE-99

Description

Polyurethane-99 is a synthetic polymer widely used in cosmetic and skincare formulations for its film-forming and water-resistant properties. This ingredient belongs to the family of polyurethanes, which are known for their versatility and durability in various applications. In skincare, Polyurethane-99 functions primarily as a film former, creating a protective barrier on the skin's surface.

The molecular structure of Polyurethane-99 allows it to form a flexible, breathable film that adheres well to the skin. This film helps to lock in moisture, enhance product longevity, and provide a smooth, even appearance to the skin. Its water-resistant qualities make it particularly valuable in long-wearing makeup formulations and sun protection products.

Polyurethane-99 is often incorporated into foundations, concealers, and other color cosmetics to improve their stay-put properties and resistance to transfer. In skincare, it can be found in serums and moisturizers to enhance their occlusive effects. The ingredient is generally well-tolerated by most skin types and is considered safe for cosmetic use at typical concentrations. However, as with any synthetic polymer, some individuals may experience sensitivity, so patch testing is recommended for those with reactive skin.
