Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 231 words
An aqueous cleaning composition to be applied from a squirt bottle comprising (a) about 5 up to 20 weight percent of particulate abrasive selected from the group consisting of diatomaceous earth, calcium carbonate, Ca 3 (PO 4 ) 2 , Ca(PO 3 ) 2 , zeolite feldspar, zirconium silicate, calcium silicate, titanium oxide, ZnO 2 , CaO, Al 2 C 3 and silica; (b) a two part thickener consisting essentially of a mixture of fumed silicon dioxide and smectite clay, the fumed silicon dioxide being present in weight percent amount between about 1 and 5, the clay being present in weight percent amount between about 4 and 15; (c) about 18 up to 40 weight percent weak aqueous hypo-halite bleach solution, the hypo-halite selected from the group consisting of sodium hypochlorite, potassium hypochlorite, calcium hypochlorite, magnesium hypochlorite, lithium hypochlorite and hypobromite; (d) about 2 up to 15 weight percent alkaline builder salt selected from the group consisting of potassium carbonate, Na 2 CO 3 , NaOH, KOH, Na 4 P 2 O 7 , K 4 P 2 O 7 , Na 5 P 3 O 10 , K 4 P 3 O 10 , Na 3 PO 4 , K 3 PO 4 , NaSiO 3 , Na 2 O: 2SiO 2 , and (e) water in an amount which is in excess of 50% by weight of the composition.
Claim 2
Dependent Claim 231 words
An aqueous cleaning composition to be applied from a squirt bottle comprising (a) about 5 up to 20 weight percent of particulate abrasive selected from the group consisting of diatomaceous earth, calcium carbonate, Ca 3 (PO 4 ) 2 , Ca(PO 3 ) 2 , zeolite feldspar, zirconium silicate, calcium silicate, titanium oxide, ZnO 2 , CaO, Al 2 C 3 and silica; (b) a two part thickener consisting essentially of a mixture of fumed silicon dioxide and smectite clay, the fumed silicon dioxide being present in weight percent amount between about 1 and 5, the clay being present in weight percent amount between about 4 and 15; (c) about 18 up to 40 weight percent weak aqueous hypo-halite bleach solution, the hypo-halite selected from the group consisting of sodium hypochlorite, potassium hypochlorite, calcium hypochlorite, magnesium hypochlorite, lithium hypochlorite and hypobromite; (d) about 2 up to 15 weight percent alkaline builder salt selected from the group consisting of potassium carbonate, Na 2 CO 3 , NaOH, KOH, Na 4 P 2 O 7 , K 4 P 2 O 7 , Na 5 P 3 O 10 , K 4 P 3 O 10 , Na 3 PO 4 , K 3 PO 4 , NaSiO 3 , Na 2 O: 2SiO 2 , and (e) water in an amount which is in excess of 50% by weight of the composition.
Claim 3
Dependent Claim 42 words
The cleansing composition of claim 1 wherein said fumed silicon dioxide is present in an amount which is about 1% by weight of the composition, and said clay is present in an amount which is about 4% by weight of the composition.
Claim 4
Dependent Claim 25 words
The cleansing composition of claim 1 wherein said alkaline builder salt is present in an amount which is about 2% by weight of the composition.
Claim 5
Dependent Claim 30 words
The cleansing composition of claim 1 wherein said builder salt consists of potassium carbonate and is present in amount sufficient to keep undissolved particles in suspension and to minimize syneresis.
Claim 6
Dependent Claim 18 words

Claim 7
Dependent Claim 27 words
The cleansing composition of claim 5 wherein said bleach consists of 51/4% sodium hypochlorite present in an amount which is about 18% by weight of the composition.
Claim 8
Dependent Claim 39 words
The cleansing composition of claim 1 including about 0.3 up to 5 weight percent bleach stable detergent selected from the group consisting of sodium lauryl sulfate, potassium lauryl alkyl sulfate, sodium stearyl alkyl sulfate and potassium stearyl alkyl sulfate.
Claim 9
Dependent Claim 28 words
The cleansing composition of claim 7 wherein said detergent consists of sodium lauryl sulfate present in an amount which is less than 1% by weight of the composition.
Claim 10
Dependent Claim 15 words
The cleansing composition of claim 7 including about 0.1 up to 1 weight percent isobornylacetate.
