Science
Mechanism of Action
This ingredient functions by forming organized liquid crystal structures within an emulsion that parallel the skin's own barrier. Its anionic phosphate group provides a 'substantive' effect, meaning it has a natural affinity for the skin's surface, which enhances the penetration of co-formulated actives while providing a long-lasting, conditioned feel without residual greasiness.
Research
Clinical Evidence
High confidence2.5%
Key findings
- 01 Croda Personal Care technical assessments demonstrate that at 2-4%, it acts as a primary emulsifier to accelerate the release of active ingredients.
- 02 Clinical formulation data from SkinBetter Science indicates that even at 0.1-1%, it effectively stabilizes fluid serums and enhances the delivery of water-soluble antioxidants.

Dusting Analysis
Because it functions effectively as a stabilizer at very low concentrations (0.1%), it is rarely 'dusted.' However, if a product claims it as a primary delivery vehicle or emulsifier at concentrations below 0.1%, its functional impact is negligible.
The Formula
Formulation
Stability
Displays exceptional hydrolytic stability, even in highly acidic environments such as AHA/BHA chemical exfoliants. It typically requires in situ neutralization with a base like Sodium Hydroxide to reach its full emulsifying potential.

Safety
Safety Profile
Manufacturing processes are strictly controlled to keep 1,4-dioxane levels below 1 ppm. Usage should be avoided on severely damaged or burned skin to prevent potential systemic absorption of PEG-related compounds.
