Science
Mechanism of Action
Arachideth-27 functions by lowering the interfacial tension between oil and water phases. With a high Hydrophilic-Lipophilic Balance (HLB) of approximately 16.0, it acts as a powerful solubilizer that anchors oily components into water-based serums and lotions, preventing phase separation while remaining gentle on the skin's lipid barrier.

Key findings
- 01 Clinical evaluations conducted by the Cosmetic Ingredient Review (CIR) on Alkyl PEG Ethers demonstrate that Arachideth-27 is non-sensitizing and maintains skin barrier integrity when used at standard formulation levels.
Transparency
Dusting Analysis
As a functional texture enhancer and emulsifier rather than a primary active, it is typically used at concentrations between 1% and 10% to achieve structural stability. Levels below 0.5% in a complex emulsion may indicate 'label dusting' without providing functional benefit.
The Formula
Formulation
Stability
Highly resilient to hydrolysis across a wide pH spectrum due to its lack of ester bonds. It maintains stability in the presence of electrolytes and various surfactant systems.
Synergies
- Lipophilic vitamins
- Essential fatty acids
- Cationic surfactants
Conflicts
- Strong oxidizing agents
- High concentrations of phenolic compounds
Safety
Safety Profile
Safety is contingent on modern purification processes that strictly limit 1,4-dioxane by-products during ethoxylation.
