pentaerythrityl tetraisostearate

Description

Pentaerythrityl tetraisostearate is a synthetic ester derived from pentaerythritol and isostearic acid. This multifunctional ingredient serves as an emollient, binder, and film-forming agent in various cosmetic and skincare formulations. Its molecular structure consists of a pentaerythritol core with four isostearic acid chains attached, resulting in a highly branched molecule.

This compound exhibits excellent stability and compatibility with a wide range of cosmetic ingredients. It provides a smooth, non-greasy feel to products while enhancing their spreadability and adherence to the skin. Pentaerythrityl tetraisostearate is particularly valued in lip products, such as lipsticks and lip glosses, where it contributes to long-lasting wear and improved texture.

In skincare formulations, this ingredient helps to create a protective barrier on the skin's surface, reducing transepidermal water loss and enhancing moisture retention. It also aids in the even distribution of other active ingredients throughout the product. Pentaerythrityl tetraisostearate is generally well-tolerated by most skin types and is considered safe for use in cosmetics at current concentrations, as assessed by regulatory bodies such as the Cosmetic Ingredient Review (CIR) expert panel.
