Polyester-8

Description

Polyester-8 is a synthetic polymer used in various cosmetic and personal care formulations. This ingredient functions primarily as a film-forming agent and viscosity controller, providing structure and stability to products. Chemically, it is a copolymer of adipic acid, neopentyl glycol, and trimellitic anhydride.

In skincare and cosmetic applications, Polyester-8 contributes to the texture and feel of products, helping to create smooth, even formulations. It aids in the even distribution of active ingredients and can enhance the product's ability to adhere to the skin or hair. This property makes it particularly useful in long-wearing makeup formulations and hair styling products.

Polyester-8 is generally considered safe for use in cosmetics and is approved by regulatory bodies in various concentrations. It is non-comedogenic, meaning it is unlikely to clog pores. The ingredient is often used in conjunction with other film-formers and emollients to achieve desired product characteristics.

While Polyester-8 does not provide direct skincare benefits, its role in improving product performance and stability indirectly contributes to the overall efficacy of skincare and cosmetic formulations. It is compatible with a wide range of other cosmetic ingredients, making it a versatile choice for formulators.
