Verdict

HASE-type associative thickener combining carbomer-like alkali-swelling with hydrophobic steareth-20 chain association, delivering synergistic thickening in surfactant systems. Requires neutralization; performance heavily dependent on surfactant type and concentration. Anionic character means electrolyte sensitivity similar to carbomers, partially offset by associative mechanism. Subject to EU REACH SPM review for crosslinked grades.

US Note

No US federal restriction. Used in cleansers and conditioning products.
