Science
Mechanism of Action
Functions by reducing interfacial tension between oil and water phases through its ethoxylated structure containing 9 moles of ethylene oxide. Its secondary alcohol base and high polarity enable effective emulsification and solubilization while remaining on the skin's surface due to its large molecular size.

Key findings
- 01 Non-irritating to rabbit skin in dermal irritation assessment
- 02 Mild skin irritant in human subjects when used in citrate buffer
Transparency
Dusting Analysis
Primarily a functional ingredient for emulsification and solubilization rather than active benefits, making dusting unlikely and unnecessary
The Formula
Formulation
Stability
Exceptionally stable across wide pH range with resistance to hard water, acids, and alkalis. Does not significantly affect viscosity or foam characteristics of final formulation.
Synergies
- amodimethicone
- fragrances
- essential oils
- silicones
Conflicts
- strong oxidizing agents
Safety
Safety Profile
Safe when formulated to be non-irritating. Typical concentrations are up to 8% in rinse-off products and 1.8-2% in leave-on applications. Minimal dermal penetration expected due to high polarity and molecular weight.
