Science
Mechanism of Action
It reduces surface tension at the oil-water interface, forming unique liquid crystalline structures. This mechanism stabilizes formulas with high lipid content, ensuring emulsion integrity and stability.

Key findings
- 01 Manufacturer data indicates that within a blend, concentrations of 2.0-6.0% effectively stabilize high oil-phase emulsions (up to 30% oil) by forming liquid crystals and improving sensorial spreadability.

The Formula
Formulation
Stability
Highly stable in high-oil load systems (30%+) and heat stable up to 80°C during processing. Optimal performance often achieved in liquid crystal emulsions.
Synergies
- Cetearyl Alcohol
- Glyceryl Stearate (for liquid crystal emulsions)
Conflicts
- Strong oxidizing agents
- Highly acidic environments below pH 3.0 (potential ether linkage instability long-term)
Safety
Safety Profile
Almondeth-20, an alkyl PEG ether, is generally considered safe by CIR when formulated to be non-irritating, consistent with the broader safety assessment of PEG-derivatives of fatty acids/oils.
