Science
Mechanism of Action
This ingredient effectively reduces interfacial tension, which is vital for forming stable oil-in-water emulsions. As a surfactant, ISOCETETH-10 lowers the surface tension of cosmetic products, facilitating even distribution on the skin and contributing to cleansing properties by aiding in the solubilization of impurities. Its balanced lipophilic and hydrophilic structure allows it to efficiently bridge diverse phases within a formula.

Stability
ISOCETETH-10 exhibits robust stability across an environmental pH range of 4.0 to 9.0, owing to its polyethylene glycol ether structure which is resistant to hydrolysis. It serves as an effective emulsifier for oil-in-water emulsions, a co-emulsifier in complex cream and lotion systems, and can solubilize lipophilic compounds like perfumes into aqueous solutions. For optimal and stable emulsions, it is often best utilized in combination with other emulsifiers.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed Alkyl PEG Ethers, including ISOCETETH-10, as safe with specific use restrictions. Based on analogue data (ISOCETETH-20), it is deemed unlikely to be a skin sensitizer. However, the CIR noted 'weight of evidence unknown/unassessed' for direct skin, eye, or lung irritation for ISOCETETH-10. Products containing ISOCETETH-10 are permitted in EWG VERIFIED formulations, provided they adhere to use restrictions and warnings regarding potential 1,4-Dioxane contamination. Maximum reported use concentrations for an analogue are 25% in rinse-off products and 5% in leave-on products. SCCS has not specifically assessed this ingredient.
