Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
93 words
A powdered carpet deodorizer and freshener composition consisting essentially of: (a) from about 57 to about 73 weight-percent of an inorganic salt selected from the group consisting of alkali metal and alkaline earth metal sulfates, bicarbonates and chlorides; (b) from about 25 to about 40 weight-percent of an aluminum silicate clay derived from pyrophyllite and having a particle size distribution of from about 10 to about 60, microns; (c) from about 1 to about 2 weight-percent of a liquid agglomerating agent; and (d) from about 1 to about 2 weight-percent of a fragrance.
Claim 2
Dependent Claim
93 words
A powdered carpet deodorizer and freshener composition consisting essentially of: (a) from about 57 to about 73 weight-percent of an inorganic salt selected from the group consisting of alkali metal and alkaline earth metal sulfates, bicarbonates and chlorides; (b) from about 25 to about 40 weight-percent of an aluminum silicate clay derived from pyrophyllite and having a particle size distribution of from about 10 to about 60, microns; (c) from about 1 to about 2 weight-percent of a liquid agglomerating agent; and (d) from about 1 to about 2 weight-percent of a fragrance.
Claim 3
Dependent Claim
14 words
The composition of claim 1 wherein the inorganic salt is an alkali metal salt.
Claim 4
Dependent Claim
14 words

Claim 5
Dependent Claim
43 words
The composition of claim 1 consisting essentially of: (a) 62.5 percent by weight of sodium sulfate; (b) 35.0 percent by weight of an aluminum silicate clay; (c) 1.5 percent by weight of dipropylene glycol; and (d) 1.0 percent by weight of a fragrance.
Claim 6
Independent Claim
125 words
A method for deodorizing and refreshing a carpet which comprises applying to the carpet, in an amount effective to deodorize and freshen the carpet, a powdered carpet deodorizer and freshener composition consisting essentially of: (a) from about 57 to about 73 weight-percent of an inorganic salt selected from the group consisting of alkali metal and alkaline earth metal sulfates, bicarbonates and chlorides; (b) from about 25 to about 40 weight-percent of an aluminum silicate clay derived from pyrophyllite and having a particle size distribution of from about 10 to about 60 microns; (c) from about 1 to about 2 weight-percent of a liquid agglomerating agent; and (d) from about 1 to about 2 weight-percent of a fragrance; and thereafter removing the composition from the carpet.
