POLYURETHANE-34

Description

Polyurethane-34 is a synthetic polymer widely used in cosmetic and skincare formulations as a film-forming agent and texture enhancer. This ingredient belongs to the family of polyurethanes, known for their versatility and ability to create flexible, durable films on the skin's surface.

In skincare products, Polyurethane-34 functions as a conditioning agent, helping to improve the feel and appearance of the skin. It forms a thin, breathable layer that can help lock in moisture and protect against environmental stressors. This film-forming property also contributes to the long-wearing capabilities of makeup products, particularly in foundations and mascaras.

Polyurethane-34 is valued for its ability to provide a smooth, even application and enhance the overall texture of formulations. It can help reduce the tackiness of certain ingredients and improve the spreadability of products. Additionally, this polymer can contribute to water resistance in sunscreens and other protective skincare items.

While generally considered safe for topical use, as with any synthetic ingredient, some individuals may experience sensitivity. It's important to patch test new products containing Polyurethane-34, especially for those with sensitive skin or a history of allergic reactions to cosmetic ingredients.
