Mechanism of Action
As a surfactant, TRILAURETH-9 CITRATE functions by reducing the surface tension between different phases. This action enables it to encapsulate and lift away dirt and oils from surfaces, providing cleansing benefits. Concurrently, its emulsifying capability allows for the creation of stable, finely dispersed mixtures of typically immiscible liquids, such as oil and water, by forming a protective interface around the dispersed phase.

Stability
TRILAURETH-9 CITRATE is instrumental in achieving and maintaining emulsion stability, preventing phase separation in complex formulations. The optimal pH range of 6.0-8.0 is noted for Triethyl Citrate, a related compound, suggesting a similar preferred environment for TRILAURETH-9 CITRATE's stability and performance.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed TRILAURETH-9 CITRATE, within the broader category of alkyl citrate esters, safe for use in cosmetic products under current practices. Although an earlier CIR report in 2011 initially indicated 'Insufficient Data' for TRILAURETH-9 CITRATE, subsequent comprehensive assessments of alkyl citrate esters led to a conclusion of safety. No specific SCCS opinion or dedicated FDA status for TRILAURETH-9 CITRATE was identified, though Triethyl Citrate, a chemically related compound, holds a Generally Recognized As Safe (GRAS) status by the FDA.
