Science
Mechanism of Action
Arachideth-37 functions as a bridge between oil and water phases, utilizing a high Hydrophilic-Lipophilic Balance (HLB) of approximately 16.9. By significantly reducing surface tension, it ensures that active ingredients remain uniformly distributed throughout a formula, preventing separation and enhancing application consistency.

Dusting Analysis
As a functional emulsifier rather than a primary active, it is rarely 'dusted' for marketing claims; however, concentrations below 0.1% may indicate insufficient levels for formula stabilization in complex emulsions.
The Formula
Formulation
Stability
Highly resilient due to stable ether linkages. It maintains structural integrity across a wide pH spectrum and is notably more temperature-resistant than many ionic alternatives.
Synergies
- Low HLB co-emulsifiers
- Lipophilic actives
- Mineral UV filters
Conflicts
- High electrolyte concentrations
- Strong oxidizing agents
Safety
Safety Profile
Safe for cosmetic use when purified to remove ethoxylation byproducts like 1,4-dioxane and ethylene oxide. It is non-irritating when formulated correctly.
