Independent Claim
36 words
A dry carpet cleaning and deodorizing composition comprising about 85 to 99.8% of hydrated sodium borate, about 0.2 to 15% of water-insoluble hydrated metal aluminosilicate and about 0.01 to 5% of perfume, said percentages by weight.
Claim 2
Dependent Claim
36 words
A dry carpet cleaning and deodorizing composition comprising about 85 to 99.8% of hydrated sodium borate, about 0.2 to 15% of water-insoluble hydrated metal aluminosilicate and about 0.01 to 5% of perfume, said percentages by weight.
Claim 3
Dependent Claim
21 words
A composition according to claim 1 in which about 0.05 to 5% by weight of cationic quaternary ammonium salt is included.
Claim 4
Dependent Claim
22 words
A composition according to claim 1 in which said hydrated sodium borate is selected from sodium tetraborate pentahydrate and sodium tetraborate decahydrate.
Claim 5
Dependent Claim
16 words
A composition according to claim 1 in which said hydrated metal aluminosilicate is hydrated sodium aluminosilicate.
Claim 6
Dependent Claim
30 words
A composition according to claim 1 comprising about 95 to 98% hydrated sodium tetraborate, about 1 to 4% of water-insoluble hydrated sodium aluminosilicate, and about 0.01 to 5% of perfume.
Claim 7
Dependent Claim
36 words
