Science
Mechanism of Action
This ingredient functions primarily as a surfactant, actively lowering the surface tension of liquids to facilitate the fine dispersion of oil and water components. This action generates lather and foam, effectively binding with fatty secretions, dirt, and oil from the skin and hair, allowing them to be effortlessly rinsed away. Additionally, it serves as an emulsifying agent, contributing to formulation stability and ensuring the uniform distribution of conditioning components.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Magnesium Laureth-3 Sulfosuccinate is safe under current practices of use and concentration, provided it is formulated to be non-irritating. While generally considered mild, there is a potential for ocular or skin irritation if not properly compounded. This ingredient may metabolize into Laureth-3 and sulfosuccinic acid; related sulfosuccinates are recognized as safe by regulatory bodies such as the US FDA under established guidelines.
