Science
Mechanism of Action
As an anionic surfactant, Sodium Oleyl Methyl Isethionate functions by effectively interacting with and emulsifying dirt, excess oil, and environmental pollutants present on the skin's surface. This action allows these impurities to be easily lifted and rinsed away with water, promoting a clean complexion without stripping essential moisture.

Stability
This ingredient maintains optimal stability in aqueous formulations within a pH range of 4.5 to 8.5, aligning with the stability profiles of related isethionate surfactants. While most stable between pH 6-8 at ambient temperatures, hydrolysis may occur outside the broader 4.5-8.5 range.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of isethionate salts, including Sodium Oleyl Methyl Isethionate, for their use in cosmetic products. The panel concluded these ingredients are safe under current practices and concentrations, provided formulations are designed to be non-irritating. While a precise maximum concentration for this specific ingredient was not detailed, closely related isethionate salts have been deemed safe in rinse-off products at concentrations up to 50% and in leave-on products up to 17%.
