Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
A granular detergent composition consisting essentially of I. from 10 to 31% by weight of synthetic organic surfactant component consisting essentially of a mixture of a. alpha-olefin sulfonate having from 12 to 18 carbon atoms, and b. poly(oxyethylene)-poly(oxypropylene) alkyl ether in which the alkyl has from 9 to 15 carbon atoms, and containing from 6 to 22 ethylene oxide units and from 2 to 8 propylene oxide units, the weight ratio of component a/component b being in the range of from 10/3 to 1/1, II. the balance is essentially water-soluble inorganic builder.
Claim 2
Dependent Claim
92 words
A granular detergent composition consisting essentially of I. from 10 to 31% by weight of synthetic organic surfactant component consisting essentially of a mixture of a. alpha-olefin sulfonate having from 12 to 18 carbon atoms, and b. poly(oxyethylene)-poly(oxypropylene) alkyl ether in which the alkyl has from 9 to 15 carbon atoms, and containing from 6 to 22 ethylene oxide units and from 2 to 8 propylene oxide units, the weight ratio of component a/component b being in the range of from 10/3 to 1/1, II. the balance is essentially water-soluble inorganic builder.
Claim 3
Dependent Claim
21 words
A granular detergent composition according to claim 1, in which said alpha-olefin sulfonate contains up to 10% by weight of disulfonate.
Claim 4
Dependent Claim
16 words
A granular detergent composition according to claim 1, in which said builder is mainly sodium pyrophosphate.
Claim 5
Dependent Claim
37 words
A granular detergent composition according to claim 1, in which said organic builder is comprised of sodium silicate in which the mole ratio of Na 2 O:SiO 2 is in the range of from 1:2.8 to 1:3.4.
Claim 6
Dependent Claim
89 words
A granular detergent composition according to claim 1, containing from 12 to 23% by weight of said alpha-olefin sulfonate, from 4 to 12% by weight of said poly(oxyethylene)-poly(oxypropylene) alkyl ether, from 10 to 15% by weight of sodium silicate in which the mole ratio of Na 2 O:SiO 2 is in the range of from 1:2.8 to 1:3.4, up to 20% by weight of sodium tripolyphosphate, up to 15% by weight of sodium pyrophosphate, up to 10% by weight of sodium carbonate, and the balance is essentially sodium sulfate.
Claim 7
Dependent Claim

A granular detergent composition according to claim 5, containing from 15 to 20% by weight of sodium tripolyphosphate and which is free of sodium pyrophosphate.
Claim 8
Dependent Claim
25 words
A granular detergent composition according to claim 5, containing from 10 to 15% by weight of sodium pyrophosphate and which is free of sodium tripolyphosphate.
