POLYURETHANE-40

Description

Polyurethane-40 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 family of polyurethanes, which are known for their durability, flexibility, and resistance to water and oils. In skincare products, Polyurethane-40 creates a protective barrier on the skin's surface, helping to lock in moisture and shield against environmental stressors.

The "40" in its name refers to the molecular weight of the polymer, which influences its specific properties and applications. Polyurethane-40 is particularly valued for its ability to improve the spreadability and feel of formulations, lending a smooth, silky texture to creams, lotions, and foundations. It also enhances the long-wearing properties of makeup products, contributing to better adherence and extended wear time.

This ingredient is generally well-tolerated by most skin types and is considered non-comedogenic, making it suitable for use in products designed for acne-prone skin. Polyurethane-40 is often found in water-resistant sunscreens, long-lasting foundations, and anti-aging serums where its film-forming properties help to maintain product efficacy throughout the day.
