Science
Mechanism of Action
It functions as a Hydrophobically Modified Alkali-Swellable Emulsion (HASE). Once neutralized within a formula, its polymer chains uncoil and deploy hydrophobic 'hooks' that interlock, creating a resilient 3D architecture that suspends oil droplets and enhances product viscosity.
Research
Clinical Evidence
High confidence1%
Key findings
- 01 Clinical HRIPT protocols confirm that at 1.0% concentration, the ingredient shows no significant potential for irritation, sensitization, or phototoxicity.
- 02 Comparative stability testing indicates superior rheology modification and emulsion stabilization between 0.5% and 5.0% without inducing surfactant-related skin stress.

Dusting Analysis
As a functional rheology modifier, using this ingredient below 0.5% typically suggests it is being used for label claims rather than structural performance, as it requires specific concentrations to trigger its thickening mechanism.
The Formula
Formulation
Stability
Supplied as a low-pH liquid that must be neutralized with an alkaline base to activate its thickening properties. It maintains excellent stability in electrolyte-rich environments.
Synergies
- Non-ionic surfactants
- Glycerin
- High-load oil phases
Conflicts
- Environments with pH below 6.0
- Divalent cations (calcium/magnesium) at high levels
- Strongly cationic surfactants
Safety
Safety Profile
The CIR Expert Panel designates it safe when formulated to be non-irritating; manufacturing processes often include vacuum stripping to ensure purity from 1,4-dioxane.
