The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the safety of 4 ammonium hectorite compounds used in cosmetics: disteardimonium hectorite, dihydrogenated tallow benzylmonium hectorite, stearalkonium hectorite, and quaternium-18 hectorite. These ingredients function in cosmetics mainly as nonsurfactant suspending agents. The Panel reviewed available animal and human data and concluded that these ammonium hectorite compounds were safe as cosmetic ingredients in the practices of use and concentration as given in this safety assessment.

“…Less work has been done on suspensions in oil, with and without lipophilic suspending agents. Lesshafft (1966) evaluated dispersions which contained various concentrations of dimethyl dialkyl ammonium hectorite (bentone 38) and ethanol in light mineral oil, and showed that they possessed yield values. Aoki et al (1968Aoki et al ( ,1969 investigated flocculation of the dispersed phase and structural viscosity in calcium carbonate in oil suspensions.…”

Significant advances in rheology of pharmaceutical and allied materials since 1965 are covered in a review of 292 references. The subject matter is divided into considerations of powders, suspensions and suspending agents, semi-solids (creams and ointments), emulsions, suppositories and pessaries, foam aerosols and a general section. Material related to tablets, biorheology, and surface and interfacial films is not considered.
