Science
Mechanism of Action
This compound functions by significantly reducing the interfacial tension between oil and water phases, thereby enabling their stable amalgamation into a homogenous emulsion. As a surfactant, it lowers the surface tension of the formulation itself, which promotes uniform product distribution upon application and can contribute to gentle cleansing.

Dusting Analysis
As a fundamental emulsifying and surfactant agent, STEARETH-15 is a functional ingredient supporting formulation stability and texture, rather than an active ingredient prone to marketing exaggeration or 'dusting'.
The Formula
Formulation
Stability
STEARETH-15 exhibits general stability under normal formulation conditions and is effective in creating stable emulsions. While a specific optimal pH range for STEARETH-15 is not explicitly detailed, related Steareth compounds are known for their stability across broad pH ranges.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded STEARETH-15, as part of the Steareth group, is safe for use in cosmetics under current practices, a decision reaffirmed in 2006 based on data from chemically similar Steareth-2, -10, and -20. While ethoxylation may result in trace amounts of 1,4-dioxane, its presence can be controlled through purification. The SCCS has not independently assessed STEARETH-15.
