POLYURETHANE-48

Description

Polyurethane-48 is a synthetic polymer widely used in cosmetic and skincare formulations. This ingredient belongs to the family of polyurethanes, known for their versatility and film-forming properties. In skincare products, Polyurethane-48 functions primarily as a film former and texture enhancer.

The molecule forms a flexible, breathable film on the skin's surface, which helps to improve product adherence and longevity. This film-forming ability makes Polyurethane-48 particularly useful in long-wearing makeup formulations, sunscreens, and other products requiring extended wear time. It also contributes to a smooth, even application of products.

Polyurethane-48 is valued for its ability to enhance the texture of formulations, providing a silky, non-greasy feel upon application. This characteristic makes it a popular choice in lightweight, fast-absorbing products. The 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.

In addition to its cosmetic benefits, Polyurethane-48 can help protect the skin from environmental stressors by creating a barrier against pollutants and other external aggressors. Its water-resistant properties also make it beneficial in water-resistant or sweat-proof formulations.
