Science
Mechanism of Action
This ether carboxylic acid operates through a dual-nature molecular structure: a hydrophobic cetyl/stearyl chain anchors to lipophilic debris, while a hydrophilic polyoxyethylene carboxylic acid head group binds to the water phase. By reducing interfacial tension, it facilitates the removal of impurities and stabilizes oil-in-water emulsions, remaining resistant to hydrolysis across varied pH environments.

Dusting Analysis
As a functional surfactant and emulsifier, this ingredient is typically used at concentrations between 0.5% and 5.0% to achieve structural integrity and cleansing performance; concentrations below 0.5% are generally insufficient for primary surfactant activity.
The Formula
Formulation
Stability
Highly stable due to ether linkages that resist breakdown. It functions most effectively in its neutralized salt form within slightly acidic to neutral ranges.
Synergies
- Cationic conditioning agents
- Mild amphoteric surfactants
Conflicts
- Strong oxidizing agents
- Aggressive cationic polymers
Safety
Safety Profile
Belongs to the alkyl ether carboxylic acid group; high-purity grades are required to ensure 1,4-dioxane levels remain below 1 ppm through vacuum stripping.
