Science
Mechanism of Action
This ingredient functions primarily as a surfactant and cleansing agent by lowering the surface tension between different phases (e.g., oil and water), allowing them to mix and lift away debris from the skin's surface.

The Formula
Formulation
Stability
As a sodium salt of a fatty acid, Sodium Dilinoleate exhibits good solubility and stability in neutral to alkaline aqueous environments, with optimal performance typically observed between pH 7.0 and 10.0. Formulation in acidic conditions may lead to the precipitation of insoluble dilinoleic acid.
Conflicts
- Acidic pH conditions (below 7.0)
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Sodium Dilinoleate safe for cosmetic use, provided it is formulated within concentration or use limitations to prevent irritation. While similar dimer dilinoleate esters have reported maximum concentrations (e.g., Diisopropyl Dimer Dilinoleate up to 53% in lipsticks), a specific maximum concentration for Sodium Dilinoleate itself has not been explicitly defined in readily available CIR summaries. No direct FDA 'approved' or 'GRAS' status is specified.
