PPG-2-CETETH-5.

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

PPG-2-Ceteth-5 is a versatile synthetic non-ionic polymer primarily functioning as a surfactant, emulsifier, and emollient in skincare. It facilitates the stable blending of water and oil phases, while also imparting a smooth, conditioning feel to the skin. This ingredient is well-regarded for its wide compatibility and stabilizing properties in diverse formulations.

Solubilizer Emollient Emulsifying Agent Wetting Agent Fragrance Functional Surfactant Humectant

Science

Mechanism of Action

On the skin, PPG-2-Ceteth-5 acts as an emollient, forming a lightweight, protective barrier that helps reduce transepidermal water loss (TEWL) and imparts a dry, silky tactile sensation. It also functions as a humectant, drawing moisture to the skin. In formulations, it serves as a non-ionic surfactant and emulsifying agent, effectively dispersing and blending water and oil-based ingredients to prevent separation. Furthermore, it excels as a solubilizer for challenging oil-loving actives and fragrances, and as a wetting agent, helping to mitigate the harsh, degreasing effects of strong cleansers.

Stability

PPG-2-Ceteth-5 demonstrates exceptional stability across a broad pH range of 3 to 12. It exhibits high compatibility with various other surfactants and possesses strong solubilization capabilities, allowing for the stable incorporation of challenging oils and fragrances into emulsions without compromising their integrity. Its presence can enhance emulsion stability, improve the water dispersibility of actives in antiperspirants, and prevent issues like wet cracking in solid soap bars.

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PPG-2-Ceteth-5 and related PPGs are safe when used in cosmetic formulations, provided the finished products are non-irritating. Manufacturers must adhere to proper filtration protocols to eliminate potential trace contamination by known carcinogens such as ethylene oxide and 1,4-dioxane. Its inclusion in the FDA Global Substance Registration System (GSRS) confirms its official identification and recognition.
