Expert Verdict

Natural smectite clay (lithium magnesium silicate) used in two distinct applications: unmodified for aqueous phase thickening, and organically-modified (Stearalkonium Hectorite, Disteardimonium Hectorite) for oil-phase and silicone-phase thickening. This dual functionality makes hectorite family clays uniquely versatile across both water- and oil-based formulation platforms. Use 1.0โ€“3.0%. Mineral origin exempts from EU REACH SPM restriction.
