HOW IT WORKS
PEG-150 Distearate increases viscosity by forming structured networks within surfactant systems. Its non-ionic nature allows it to thicken formulations without interacting strongly with other surfactants, making it especially effective in complex or sulfate-free cleansing systems.
CONCENTRATION & SOLUBILITY
Recommended Usage Levels
Shampoos & cleansers: 0.5–3.0%
High-viscosity systems: 1.0–5.0%
(Use level depends on surfactant system and desired thickness)
Solubility Details
Dispersible in water when heated
Soluble in surfactant systems
Insoluble in cold water
FORMULATION GUIDELINES
Add to the surfactant phase
Heat to 60–75°C until fully melted and dispersed
Ensure uniform mixing for consistent viscosity
Add electrolytes (if any) after viscosity adjustment
Conduct stability and compatibility testing
