Science
Mechanism of Action
By integrating a polyoxyethylene chain with a carboxylic acid group, this ingredient lowers the surface tension of water to lift oils and debris. Its unique structure allows it to maintain high-performance foaming and detergency even in hard water or acidic environments, mimicking the skin's natural pH and preventing the protein denaturation often caused by harsh sulfates.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 Clinical evaluations demonstrate that concentrations up to 10% function as ultra-mild surfactants with significantly lower irritancy potential than traditional sulfates.
- 02 Ocular and dermal safety studies at 5% concentrations confirm minimal to no irritation, making it suitable for sensitive area applications.
Transparency
Dusting Analysis
As a primary or secondary surfactant, it is rarely 'dusted' because its functional role in formula stability and texture requires specific concentration thresholds; however, levels below 0.1% in a cleanser would be insufficient for performance.
The Formula
Formulation
Stability
Highly stable across a broad pH spectrum. Unlike traditional soaps, it retains its efficacy at pH 4.5–5.5, the ideal range for maintaining the skin's acid mantle.
Synergies
- Amphoteric surfactants
- Glycerin
- Nonionic emulsifiers
Conflicts
- Strong oxidizing agents
- High concentrations of specific cationic polymers
Safety
Safety Profile
The CIR Expert Panel supports its safety profile in both rinse-off (up to 10%) and leave-on (typically <1%) applications when formulated to be non-irritating.
