Science
Mechanism of Action
It functions as a Newtonian associative thickener by building a three-dimensional micellar network within the water phase. Beyond viscosity control, it reduces interfacial tension to assist in the solubilization of lipophilic actives and functions as a secondary emulsifier to ensure structural integrity across varied temperatures.

Key findings
- 01 Concentrations up to 10% were confirmed as non-irritating in 28-day repeated application protocols.
- 02 Human Repeat Insult Patch Testing (RIPT) at 50-100% concentration verified the ingredient as a non-sensitizer.
- 03 Inclusion at 0.5% demonstrates synergistic viscosity enhancement when paired with electrolyte stabilizers like sodium chloride.

Dusting Analysis
Because this ingredient is primarily functional rather than a 'hero' marketing active, it is rarely 'dusted.' However, levels below 0.5% may indicate a negligible impact on the formula's structural viscosity.
The Formula
Formulation
Stability
Exhibits exceptional thermal stability and maintains performance in high-electrolyte environments. Requires heating to 70-80°C for proper integration.
Synergies
- Sodium Chloride
- Sulfate-free surfactants
- Lipophilic oils
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
While undiluted material can be an eye irritant, it is non-sensitizing in finished cosmetic concentrations. Modern manufacturing utilizing vacuum stripping ensures 1,4-dioxane impurities remain below 1 ppm.
