Polyester-5

Description

Polyester-5 is a synthetic polymer widely used in cosmetic and personal care formulations. This versatile ingredient functions primarily as a film-forming agent and viscosity controller, contributing to the texture and stability of various skincare and makeup products. Its chemical structure allows it to form a flexible, breathable film on the skin's surface, which can help improve the longevity of cosmetic applications and provide a smooth, even finish.

In skincare formulations, Polyester-5 aids in creating lightweight, non-greasy textures that are easily spreadable and quick-absorbing. It is particularly effective in oil-control products, as it can help absorb excess sebum and reduce shine. The film-forming properties of Polyester-5 also make it valuable in sun protection products, where it can enhance the water resistance of sunscreens.

Polyester-5 is generally well-tolerated by most skin types and is considered safe for use in cosmetics. However, as with any synthetic ingredient, some individuals may experience sensitivity. It is non-comedogenic, meaning it is unlikely to clog pores or exacerbate acne-prone skin. The ingredient's stability across a wide pH range makes it compatible with various formulation types and active ingredients.
