Abstract
Quaternary ammonium compositions are described which are made using diluents including soya bean oil, caster oil, mineral oils, isoparaffin/naphthenic and coconut oil. Such diluents remain as diluents in the final product and generally have a vapor pressure of 1 mm of Hg or less at 25.degree. C., and are liquid at ambient temperature. The quaternary/ammonium diluent compositions have low volatile organic compound emission rates and high flash points, and can be tailored to particular applications. Such applications include use a fabric softeners, cosmetics ingredients, deinking additives, surfactants, and reaction materials in the manufacture of organoclays.
Claims4
An organoclay made by the reaction of smectite clay and a quaternary ammonium compound contained in a quaternary ammonium composition which composition comprises a quaternary ammonium compound and a diluent other than propylene glycol, hexylene glycol and diethylene glycol where the diluent has a vapor pressure of 1 mm of mercury or less at 25.degree. C.
