POLYURETHANE-9

Description

Polyurethane-9 is a synthetic polymer widely used in cosmetic and skincare formulations as a film-forming agent and hair fixative. This versatile ingredient belongs to the broader class of polyurethanes, known for their durability and flexibility. In skincare products, Polyurethane-9 creates a thin, protective layer on the skin or hair, helping to lock in moisture and shield against environmental stressors.

The molecular structure of Polyurethane-9 allows it to form a breathable film that doesn't interfere with the skin's natural functions. This characteristic makes it particularly suitable for long-wearing makeup products, such as foundations and mascaras, where it enhances product adherence and longevity. In hair care applications, Polyurethane-9 provides hold and style retention without causing stiffness or flaking.

Polyurethane-9 is generally well-tolerated by most skin types and is considered safe for cosmetic use. However, as with any synthetic ingredient, some individuals may experience sensitivity. It's non-comedogenic, meaning it doesn't clog pores, making it suitable for use in products designed for acne-prone skin. The ingredient's water-resistant properties also contribute to its popularity in sunscreen formulations, helping to maintain UV protection during swimming or sweating.
