PPG-1-CETETH-20.

Valuable CAS 9087-53-0 / 37311-01-6 / SKIN CONDITIONING, SURFACTANT - CLEANSING

PPG-1-Ceteth-20 is a multifunctional nonionic ingredient, acting as an emulsifier, emollient, humectant, and solubilizer in skincare formulations. It stabilizes diverse product types while enhancing skin moisture retention and providing a smooth feel.

Summary

Nonionic Surfactant Emulsifier Emollient Humectant Solubilizer

Science

Mechanism of Action

This alkyl PEG/PPG ether effectively reduces surface tension within formulations, facilitating the stable co-dispersion of oil and water phases to create uniform emulsions. On the skin, it forms a protective occlusive layer that contributes to a smoother tactile sensation, actively preventing moisture loss and dehydration. It additionally helps to minimize the greasy sensation often associated with oils and reduces the visual prominence of sebum. Furthermore, it demonstrates excellent capability in solubilizing challenging lipophilic ingredients, including oils, oil-loving actives, and fragrances, into aqueous systems.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated PPG-1-Ceteth-20, along with a broader group of 131 alkyl PEG/PPG ethers, concluding its safety in current cosmetic applications and concentrations, provided formulations are non-irritating. While a precise maximum concentration for PPG-1-Ceteth-20 was not specified, a closely related compound, PPG-5-Ceteth-20, has been deemed safe for use up to 20% and is commonly incorporated at 5-20%. Manufacturers must implement rigorous filtration processes to mitigate potential contamination by ethylene oxide and 1,4-dioxane, known carcinogens, during the manufacturing process. The ingredient is recognized by the FDA Global Substance Registration System (GSRS).
