Science
Mechanism of Action
This ingredient operates by several mechanisms: as an emollient, it forms a surface film on the skin, contributing to its softness and flexibility. Its emulsifying action enables the stable blending of immiscible liquids, such as oils and water, in cosmetic formulations. Furthermore, its surfactant properties reduce surface tension, improving the spreadability and uniform application of products, and it can act as a superfatting agent, helping to replenish skin lipids.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that butyl polyoxyalkylene ethers, which include PPG-25 Butyl Ether Phosphate, are safe for use in cosmetic products when specifically formulated to be non-irritating. The panel expressed greater caution regarding smaller molecular weight PPG Butyl Ethers due to their increased potential for skin absorption. The European Union's Cosmetics Regulation generally permits these ingredients in cosmetic applications.
