POLYURETHANE-8

Description

Polyurethane-8 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 family of polyurethanes, known for their flexibility, durability, and adhesive properties. In skincare applications, Polyurethane-8 creates a thin, protective film on the skin or hair surface, providing long-lasting hold and resistance to humidity.

The compound is particularly valued in makeup products such as mascaras, eyeliners, and long-wear foundations due to its ability to improve product adherence and extend wear time. In hair care, it enhances the performance of styling products by providing a flexible hold without stiffness or flaking. Polyurethane-8 is also water-resistant, making it ideal for products designed to withstand perspiration or humid conditions.

From a safety standpoint, Polyurethane-8 is generally considered safe for cosmetic use when formulated properly. It is non-irritating to most skin types and does not penetrate beyond the skin's surface. However, as with any cosmetic ingredient, individual sensitivities may occur. The polymer's molecular weight prevents it from being absorbed into the skin, minimizing potential systemic effects.
