POLYURETHANE-29

Description

Polyurethane-29 is a synthetic polymer widely used in cosmetic and skincare formulations. This versatile ingredient functions primarily as a film-former and viscosity-controlling agent. Its unique chemical structure allows it to create a flexible, breathable film on the skin's surface, providing both protection and long-lasting wear for various cosmetic products.

In skincare applications, Polyurethane-29 enhances the texture and feel of formulations, contributing to a smooth, non-tacky finish. It is particularly valuable in water-resistant and long-wear products such as sunscreens, foundations, and mascaras. The polymer's film-forming properties help to lock in moisture and other beneficial ingredients, potentially improving product efficacy.

Polyurethane-29 is generally considered safe for use in cosmetics, with low risk of skin irritation or sensitization. Its molecular weight is typically too large for significant skin penetration, making it suitable for topical use. The ingredient is compatible with a wide range of other cosmetic components, allowing formulators flexibility in product development.

While Polyurethane-29 offers numerous benefits in cosmetic formulations, it's important to note that it is not biodegradable and may contribute to environmental concerns if not disposed of properly.
