Science
Mechanism of Action
It functions by reducing interfacial tension, allowing oils to be dispersed into water-based systems. This creates stable oil-in-water emulsions and enables the surfactant to encapsulate and lift away sebum, debris, and makeup from the skin surface during the cleansing process.
Research
Clinical Evidence
Medium confidence3%
Key findings
- 01 CIR Expert Panel (2012) analysis confirms that while pure concentrations are skin irritants, formulated products are safe when balanced for non-irritation.
- 02 SCCS assessment (2007) established an oral NOAEL of 50 mg/kg bw/day using analogous compounds, indicating low systemic toxicity.
- 03 Environmental screening (1996) indicates a specific NOEC for aquatic life between 80-550 microg/liter, highlighting the importance of wash-off concentration limits.

Dusting Analysis
As a functional emulsifier rather than an active, 'dusting' is less common; however, using it below 1% in heavy oil-based systems may lead to emulsion instability.
The Formula
Formulation
Stability
Exhibits exceptional stability across a wide pH spectrum. It possesses an HLB value of 13-14, making it highly effective for water-dispersible formulas.
Synergies
- Lipophilic surfactants
- Glycerin
- Non-polar oils
Conflicts
- High-concentration electrolyte systems
- Strong oxidizing agents
Safety
Safety Profile
Safety is concentration-dependent. The raw material is a known irritant, but it is considered safe and non-sensitizing when diluted to typical cosmetic levels (below 5%).
