Science
Mechanism of Action
As an emulsifier, ISOCETETH-25 efficiently reduces interfacial tension between immiscible phases like oil and water, enabling the formation and maintenance of stable emulsions. Its surfactant activity lowers the surface tension of a formulation, promoting uniform application and contributing to gentle cleansing. Furthermore, this nonionic ingredient, derived from isocetyl alcohol, effectively solubilizes lipophilic compounds, such as fragrances, within aqueous systems.

Formulation
Stability
ISOCETETH-25 demonstrates robust stability across a broad pH range, resisting degradation from both acidic and alkaline conditions. Its hydrophilic nature and high HLB value (estimated at 15.7, based on similar Isoceteth-20) make it an excellent oil-in-water emulsifier and solubilizer.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed alkyl PEG ethers, including ISOCETETH-25, safe for use at current concentrations provided formulations are nonirritating. Specifically, safety assessments for the closely related Isoceteth-20 supported concentrations up to 21%. There are no specific restrictions from SCCS or the FDA beyond general cosmetic regulations.
