Mechanism of Action
This ingredient functions as an emulsifier by facilitating the creation of stable, finely dispersed mixtures of oil and water, crucial for many cosmetic formulations. Simultaneously, it acts as a cleansing agent. As a member of the PPG Butyl Ether family, it is understood to improve the skin's appearance by reducing flaking and restoring suppleness, thereby contributing to skin conditioning.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed butyl polyoxyalkylene ethers, which include PPG-21 Butyl Ether, concluding their safety for cosmetic use when formulated to prevent irritation. While animal test data indicated potential for irritation, clinical testing on related PPG Butyl Ethers (e.g., PPG BE800, PPG-40 Butyl Ether) found them to be non-irritating and non-sensitizing under proper formulation conditions. Generally, the toxicity of PPG Butyl Ethers tends to decrease as their molecular weight increases.
