Expert Verdict
PEG-150 distearate forms a self-assembled gel network in surfactant solutions, providing viscosity independent of ionic strength at 0.5–2% use levels. Effective in both SLES-based and sulfate-free formulations, addressing viscosity challenges where salt-dependent thickeners fail. Ethoxylated ingredient requiring GMP control of 1,4-dioxane impurity (≤10 ppm) and not COSMOS-eligible.
