Science
Mechanism of Action
This ingredient functions by significantly lowering the interfacial tension between immiscible liquids like oil and water, thereby enabling the formation of stable emulsions. As a surfactant, it also contributes to cleansing by helping to remove impurities from the skin and hair.

Formulation
Stability
Due to its high degree of ethoxylation, STEARETH-200 demonstrates excellent water solubility and maintains stability across a broad pH range, consistent with other highly ethoxylated Steareth derivatives. It readily combines with various emulsifiers and thickeners to achieve desired texture and long-term formulation stability.

Safety
Safety Profile
The CIR Expert Panel has determined STEARETH-200 to be safe for cosmetic use, provided formulations are designed to be non-irritating. While the ethoxylation process can yield trace amounts of 1,4-dioxane, its presence can be effectively managed through purification. Due to its substantial molecular weight and typical low concentrations in products, significant dermal absorption is considered unlikely. It aligns with the general provisions of the EU Cosmetics Regulation and holds FDA approval as an indirect food additive in certain textile applications.
