Science
Mechanism of Action
This ingredient functions by lowering the interfacial tension, enabling the creation of stable emulsions. Its anionic phosphate group provides specific stabilization, while the ethoxylated fatty alcohol part balances hydrophilic and lipophilic properties.

Dusting Analysis
As an emulsifier and surfactant, this ingredient is not typically used in concentrations that would lead to 'dusting' issues associated with active ingredients.
The Formula
Formulation
Stability
Highly stable in emulsions and effective in stabilizing high-load pigment systems. It often co-formulates with pH adjusters like Ammonium Hydroxide or Triethanolamine.
Conflicts
- Cationic surfactants
- Strongly acidic conditions (may destabilize the phosphate salt)
Safety
Safety Profile
The CIR Expert Panel concluded this ingredient is safe when formulated to be non-irritating. As an ethoxylated compound, controlling 1,4-dioxane, a manufacturing byproduct, is crucial.
