ISOPHTHALIC ACID/PENTAERYTHRITOL CROSSPOLYMER BENZOATE/ISOSTEARATE

Description

Isophthalic Acid/Pentaerythritol Crosspolymer Benzoate/Isostearate is a complex synthetic polymer used in advanced skincare and cosmetic formulations. This multifunctional ingredient serves as a film former, viscosity controller, and emollient, contributing to improved texture and performance of various products.

The crosspolymer structure of this compound provides excellent stability and allows for controlled release of active ingredients in skincare formulations. Its film-forming properties create a smooth, protective layer on the skin, helping to lock in moisture and enhance the longevity of other beneficial components. The benzoate and isostearate components contribute emollient properties, offering a silky, non-greasy feel upon application.

In cosmetic products, this ingredient can improve spreadability and enhance the overall sensory experience. It is particularly useful in long-wearing makeup formulations, sunscreens, and anti-aging products where extended efficacy is desired. The polymer's ability to form a flexible film also aids in reducing the appearance of fine lines and wrinkles, providing a temporary smoothing effect.

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.
