Abstract
Flowable granular carpet cleaning compositions which do not contain borax or boric acid salts and which are readily shaken or strewn onto a carpet needing cleaning is disclosed. The compositions comprise as essential constituents: comminuted cellulose, zeolite, a inorganic salt system comprising of an (a) alkali metal carbonate, (b) an alkali metal bicarbonate, and an (c) alkali metal sesquicarbonate wherein the ratios of (a):(b):(c) is 1:0.5-2.5:0.5-2.5, one or more organic solvents, an organic or inorganic acid, anionic surfactant, and, water.
Claims23

A powdered carpet cleaning composition which comprises:
- A) 25-35% wt. cellulose absorbent,
- B) 1-4% wt. zeolite or amorphous silica or mixtures thereof,
- C) 12-16% wt. inorganic salt system comprising of (a) alkali metal carbonate, (b) an alkali metal bicarbonate, and (c) an alkali metal sesquicarbonate wherein the weight percentage ratios of (a):(b):(c) is 1:1-1.2:1-1.2;
- D) 5-7% wt. organic solvent,
- E) 0.01-3% wt. acid,
- F) 0.5-1.5% wt. anionic surfactant,
- G) 42-48.5% wt. water,
- H) 0-5% wt. optional constituents with the proviso that the composition does not contain borax or boric acid, and are at a pH in the range of 9-10.
