Science
Mechanism of Action
As a member of the butyl polyoxyalkylene ether group, PPG-2-BUTETH-3 improves the skin's surface by reducing flaking and restoring suppleness, particularly beneficial for dry or compromised skin. Its solvent properties enable the dissolution of other ingredients, while its emulsifying capabilities ensure immiscible phases, such as oils and water, remain uniformly dispersed, contributing to product stability and texture. It extends similar conditioning benefits to hair, enhancing body, suppleness, sheen, and manageability.

Stability
Polypropylene glycols and their derivatives, including PPG-2-BUTETH-3, are generally characterized by a broad range of viscosity and solubility properties and are known for very good skin tolerance. It is considered water-soluble, offering flexibility in aqueous formulations.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PPG-2-BUTETH-3, along with other butyl polyoxyalkylene ethers, is safe for use in cosmetic formulations under current practices, provided the final product is formulated to be non-irritating. While no specific maximum concentration for PPG-2-BUTETH-3 was identified, this safety assessment is contingent on appropriate formulation to prevent potential irritation, particularly for sensitive skin types, as some broader group studies suggest. The FDA monitors its usage in cosmetic products.
