Science
Mechanism of Action
It functions by reducing the surface tension between oil and water phases, utilizing its high Hydrophilic-Lipophilic Balance (HLB) value of approximately 16.6 to stabilize emulsions. The large hydrophilic portion of the molecule allows it to effectively surround and suspend oil droplets or fragrance compounds within an aqueous environment.

Transparency
Dusting Analysis
As a functional emulsifier rather than a bio-active marketing ingredient, it is rarely 'dusted' and is typically used at the necessary concentrations required for formulation stability.
The Formula
Formulation
Stability
Exhibits exceptional chemical stability due to its robust ether linkages, which resist hydrolysis in both acidic and alkaline environments.
Synergies
- Lipid-based actives
- Hydrophobic fragrance oils
- O/W co-emulsifiers
Conflicts
- Strong oxidizing agents
- Phenolic compounds
Safety
Safety Profile
Considered non-sensitizing in clinical patch tests; safety is contingent on formulating to be non-irritating.
