Abstract
Abstract The invention relates to a detergent composition comprising lipases. By inclusion of a certain immunologically defined class of lipases in a detergent composition which comprises as detergent-active material solely an anionic synthetic detergent, and as builder a water-soluble inorganic or organic builder salt, an improved overall detergency is obtained. The builder salt is typically sodium tripolyphosphate or sodium carbonate, and the lipase is typically obtained from certain Pseudomonas or Chromobacter strains.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
56 words
A detergent composition comprising as detergent-active material solely an anionic synthetic detergent, a builder and a lipase, characterised in that the builder is a water-soluble organic or inorganic builder salt and the lipase is a lipase which shows a positive immunological cross-reaction with the antibody of the lipase, producible by the microorganism Pseudomonas fluorescens IAM 1057.
Claim 2
Dependent Claim
56 words
A detergent composition comprising as detergent-active material solely an anionic synthetic detergent, a builder and a lipase, characterised in that the builder is a water-soluble organic or inorganic builder salt and the lipase is a lipase which shows a positive immunological cross-reaction with the antibody of the lipase, producible by the microorganism Pseudomonas fluorescens IAM 1057.
Claim 3
Dependent Claim
14 words
A composition according to claim 1, characterised in that the builder is pentasodium tripolyphosphate.
Claim 4
Dependent Claim
14 words
A composition according to claim 1, characterised in that the builder is sodium carbonate.
Claim 5
Dependent Claim
20 words
A composition according to claim 1, characterised in that the builder is a mixture of pentasodium tripoiyphosphate and sodium carbonate.
Claim 6
Dependent Claim
38 words
A composition according to claim 1, characterised in that the lipase also shows a positive immunological cross-reaction with the antibody of the lipase, producible by the microorganism Chromobacter viscosum var. li p olvticum NRRLB 3673 or Pseudomonas gladioli.
Claim 7
Dependent Claim
28 words
A composition according to claim 1, characterised in that the positive immunological cross-reaction showing lipase is a lipase, producible by strains of the Pseudomonas and the Chrombacter genus.
Claim 8
Dependent Claim
35 words
A composition according to claim 1, characterised in that the lipase is producible by strains of Pseudomonas fluorescens, of Pseudomonas fragi, of Pseudomonas nitroreduc- tans var. lipolyticum , of Pseudomonas gladioli, and of Chromobacter viscosum.
Claim 9
Dependent Claim
15 words
A composition according to claim 1, characterised in that it further conatins a bleaching agent.
Claim 10
Dependent Claim
15 words
A composition according to claim 1, characterised in that it further contains a proteolytic enzyme.
