Science
Mechanism of Action
Functions as an interfacial tension reducer between oil and water phases, utilizing its secondary alcohol ethoxylate structure to create stable oil-in-water emulsions. The unique secondary alcohol backbone provides superior wetting properties and natural antifoaming characteristics compared to primary alcohol variants.

Key findings
- 01 HET-CAM assay at 3.0% concentration showed mild to particularly mild irritation profile with low ocular and dermal irritation potential
- 02 CIR Expert Panel comprehensive review confirmed safety in cosmetic applications when properly formulated

Dusting Analysis
As a functional emulsifier rather than an active ingredient, dusting is not applicable to this surfactant component.
The Formula
Formulation
Stability
Demonstrates excellent stability across acidic to alkaline pH ranges common in cosmetics. Maintains performance in hard water conditions and remains stable when formulated with electrolytes.
Conflicts
- Extremely strong oxidizing agents
- Strong acids or bases (potential for gradual hydrolysis)
- High concentrations of cationic surfactants (may compromise foam stability)
Safety
Safety Profile
Maximum 10% concentration approved for rinse-off products, though typically used below 1% in leave-on formulations. Safety contingent on final product being non-irritating.
