MAGNESIUM LAURETH-8 SULFATE.

Valuable CAS 62755-21-9 / CLEANSING, SURFACTANT - CLEANSING

Magnesium Laureth-8 Sulfate is an anionic surfactant lauded for its exceptional cleansing, foaming, and emulsifying capabilities. It efficiently removes dirt and oil while ensuring product stability and uniform consistency, making it a versatile component in various skincare and haircare formulations.

Summary

Surfactant Cleansing Emulsifying

Science

Mechanism of Action

This ingredient functions as a surfactant by possessing both hydrophilic and lipophilic molecular segments. The lipophilic portion effectively binds to sebaceous secretions and environmental pollutants on the skin, while the hydrophilic segment facilitates their suspension and subsequent removal with water during rinsing. Beyond cleansing, it acts as an emulsifier, stabilizing oil-in-water mixtures critical for product integrity and consistent texture. Its capacity to generate substantial lather and foam further enhances the effective removal of impurities from skin and hair.

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Magnesium Laureth-8 Sulfate, along with related ethoxylated alcohol salts, is safe for use in cosmetic and personal care products, contingent upon formulations being non-irritating. While potential traces of manufacturing by-products like Ethylene Oxide and 1,4-Dioxane are a consideration, the risk is deemed low and manageable. The U.S. FDA indicates that the levels of 1,4-dioxane typically found in cosmetics do not present a health hazard to consumers.
