Valuable CAS 9005-00-9 (Generic) / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

STEARETH-16 is a polyethylene glycol ether of stearyl alcohol, serving as a versatile functional ingredient in cosmetic formulations. It primarily acts as an emulsifier, surfactant, and cleansing agent, critical for achieving stable product compositions.

Summary

Cleansing Emulsifying Surfactant

Science

Mechanism of Action

STEARETH-16 functions by reducing the surface tension between immiscible phases, allowing oils and water to combine and form stable emulsions. This surfactant activity also aids in the uniform distribution of product and effective cleansing.

Safety

Safety Profile

CIR Status
Safe as used with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that alkyl PEG ether compounds, including Steareth ingredients, are safe when formulated to be non-irritating. While no specific maximum concentration for STEARETH-16 was provided, related compounds like Steareth-2 and Steareth-20 were deemed safe up to 10% and 25% respectively. A potential concern is the presence of 1,4-dioxane, a by-product of ethoxylation, which can be controlled through purification steps.
