POLYURETHANE-16

Description

Polyurethane-16 is a synthetic polymer widely used in cosmetic and skincare formulations as a film-forming agent and fixative. This versatile ingredient belongs to the family of polyurethanes, known for their durability and flexibility. In skincare products, Polyurethane-16 creates a protective barrier on the skin or hair, helping to lock in moisture and enhance product longevity.

The compound is particularly valued for its ability to impart a smooth, even finish to various formulations, including foundations, mascaras, and hair styling products. Its film-forming properties contribute to improved water resistance and wear time in cosmetics. Polyurethane-16 also aids in the even distribution of other active ingredients across the skin's surface.

From a safety standpoint, Polyurethane-16 is generally considered non-irritating and well-tolerated by most skin types. It is often used in concentrations ranging from 0.5% to 10%, depending on the specific product and desired effect. While it primarily serves a functional role in formulations, some studies suggest it may have mild moisturizing properties, though this is not its primary purpose. As with any synthetic ingredient, individuals with sensitive skin should perform patch tests before widespread use.
