Claims5
A medicament, comprising a dispersion, said dispersion comprising a dispersed phase within an aqueous phase comprising deionized water, said medicament comprising:
- a) a layered hydrous magnesium silicate having binding sites in said dispersed phase;
- and
- b) a quaternary ammonium compound in said dispersed phase;
- wherein said quaternary ammonium compound is loaded into said layered hydrous magnesium silicate clay with a percentage loading relative to available layered hydrous magnesium silicate clay binding sites of greater than 200%;
- and
- wherein said dispersion is made by the method of i) dry mixing said layered hydrous magnesium silicate clay and said quaternary ammonium compound to produce a mixture;
- ii) adding water to said mixture to form a suspension;
- and iii) incubating said suspension in said water to form said dispersion.
