Science
Mechanism of Action
Steareth-3 operates by significantly lowering the interfacial tension between immiscible liquids, such as oil and water, thereby facilitating their uniform dispersion and the formation of stable emulsions essential for smooth product consistency. Additionally, its amphiphilic structure allows it to act as an emollient, promoting skin conditioning and a smoother feel, and as a cleaning surfactant to effectively emulsify and remove surface oils and impurities.

Stability
As a member of the Steareth family, Steareth-3 is instrumental in creating resilient emulsions. It is understood to maintain stability across a wide pH range, even under highly acidic or alkaline conditions, by fostering intimate mixtures between disparate phases. Its utility extends to viscosity enhancement when co-formulated with specific consistency-imparting substances.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed Steareth-3, deeming it safe for use in cosmetic applications when formulated to be non-irritating. While specific maximum concentration guidelines are not uniformly established across all product types, its safety assessment aligns with current industry practices and concentration levels. This ingredient is permissible in EU cosmetic products and manufacturers address potential trace amounts of 1,4-dioxane, a byproduct of the ethoxylation process, through rigorous purification.
