POLYURETHANE-35

Description

Polyurethane-35 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 class of polyurethanes, which are known for their durability, flexibility, and resistance to water and oils. In skincare products, Polyurethane-35 creates a protective barrier on the skin's surface, helping to lock in moisture and shield against environmental stressors.

The "35" in its name refers to the specific molecular weight and structure of this particular polyurethane variant. This characteristic influences its performance and compatibility with other ingredients in formulations. Polyurethane-35 is particularly valued for its ability to provide long-lasting hold in hair styling products without leaving a stiff or sticky residue.

In addition to its film-forming properties, Polyurethane-35 contributes to the texture and feel of products, often improving spreadability and creating a smooth finish on the skin or hair. It is generally well-tolerated by most skin types and is considered safe for use in cosmetic applications. However, as with any synthetic ingredient, some individuals may experience sensitivity, so patch testing is recommended for those with reactive skin.
