POLYESTER-27

Description

Polyester-27 is a synthetic polymer utilized in various skincare and cosmetic formulations. This ingredient functions primarily as a film-forming agent and emulsion stabilizer, contributing to the texture and longevity of products. Chemically, it is a copolymer of adipic acid, neopentyl glycol, and trimellitic anhydride, which grants it unique properties beneficial for topical applications.

In skincare formulations, Polyester-27 creates a lightweight, breathable film on the skin's surface, helping to lock in moisture and protect against environmental stressors. This film-forming capability also aids in the even distribution and adherence of active ingredients, potentially enhancing their efficacy. The ingredient's stabilizing properties help maintain the integrity of emulsions, ensuring consistent product texture and performance over time.

Polyester-27 is particularly valued in long-wearing makeup formulations, where it contributes to improved product longevity and resistance to smudging or transfer. Its low molecular weight allows for smooth application without a heavy or greasy feel. While generally well-tolerated, as with any synthetic ingredient, patch testing is recommended for individuals with sensitive skin or a history of allergic reactions to cosmetic products.
