POLYURETHANE-21

Description

Polyurethane-21 is a synthetic polymer widely used in cosmetic and skincare formulations as a film-forming agent and texture enhancer. This versatile ingredient belongs to the polyurethane family, known for its ability to create flexible, yet durable films on the skin's surface. Polyurethane-21 is particularly valued for its water-resistant properties, making it an excellent choice for long-wearing makeup and sunscreen products.

In skincare applications, Polyurethane-21 functions as a stabilizer and emulsion enhancer, improving the overall texture and feel of creams and lotions. Its film-forming capabilities help to lock in moisture and create a protective barrier on the skin, potentially enhancing the efficacy of other active ingredients. This polymer is also appreciated for its ability to impart a smooth, non-tacky finish to formulations.

Polyurethane-21 is generally well-tolerated by most skin types and is considered safe for use in cosmetic products. However, as with any synthetic ingredient, some individuals may experience sensitivity. It's important to note that while Polyurethane-21 offers numerous benefits in skincare formulations, it should be used in appropriate concentrations as determined by regulatory guidelines and product specifications.
