POLYURETHANE-42

Description

Polyurethane-42 is a synthetic polymer widely used in skincare and cosmetic formulations for its film-forming and texture-enhancing properties. This ingredient belongs to the family of polyurethanes, which are known for their versatility and ability to create flexible, durable films on the skin's surface.

In skincare products, Polyurethane-42 functions primarily as a film former and texturizer. It creates a thin, imperceptible layer on the skin that helps to improve the feel and application of various formulations. This film can also assist in maintaining skin hydration by reducing transepidermal water loss.

The '42' in its name typically refers to the specific molecular weight or structure of this particular polyurethane variant. This ingredient is often found in foundations, sunscreens, and other cosmetic products where a smooth, long-lasting finish is desired. It can enhance the water-resistance of formulations, making it particularly useful in products designed for extended wear or water exposure.

Polyurethane-42 is generally considered safe for use in cosmetics and is compatible with a wide range of other skincare ingredients. Its low irritation potential makes it suitable for various skin types, including sensitive skin.
