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 a mixture of an anionic and a nonionic detergent, an improved overall detergency is obtained. Typical suitable lipases are obtained from certain Pseudomonas and Chromobacter strains.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
A detergent composition comprising from 1 to 30% of a mixture of an anionic and a nonionic detergent-active compound in the weight ratio from 12:1 to 1:12, and an enzyme, wherein the enzyme is a lipase which is produced by the microorganisms selected from the group consisting of Pseudomonas fluorescens, Pseudomonas gladioli and Chromobacter viscosum, said composition containing the lipase in such an amount that the final composition has a lipolytic enzyme activity of from 0.005 to 100 Lipase Units per milligram.
