Claims

1. A detergent composition comprising
(a) one or more anionic surfactants;
(b) an enzyme selected from the group consisting of: a protease, a cutinase, a carbohydrase, a cellulase, a pectinase, a mannanase, an arabinase, a galactanase, a xylanase, and an oxidase; and
(c) a deoxyribonuclease (DNase),
the detergent composition not including an amylase and not including a lipase, and
the detergent composition removing from a textile or preventing from sticking to a textile, malodorous compounds or dirt (pigment soil) that are on or may be on the textile, in the presence of DNA, better than the same detergent composition that lacks the DNase,
wherein the detergent composition comprises 10-40 w/w % of the surfactants, 4-50 w/w % of a builder and 0-5 w/w % of a polymer and optionally a filler, solvents and an enzyme stabilizer.
2. The composition of claim 1, wherein the DNase is obtainable from Bacillus.
3. The composition of claim 1, wherein the detergent composition is capable of reducing adhesion of bacteria selected from the group consisting of Acinetobactersp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis, and Stenotrophomonas sp. to a surface, or releasing the bacteria from a surface to which they adhere.
4. The composition of claim 1, wherein the composition is capable of reducing malodor from wet or dry laundry, the malodor determined by sensory analysis.
5. The composition of claim 1, wherein the composition is capable of reducing E-2-nonenal from wet or dry laundry.
6. A washing method for a textile comprising:
(a) exposing the textile to a wash liquor comprising the detergent composition of claim 1, and
(b) completing at least one wash cycle.
7. The method of claim 6, further comprising rinsing the textile.
8. The method of claim 6, wherein the temperature of the wash liquor is in the range of 5° C. to 95° C.
9. The method of claim 6, wherein whiteness of the textile is maintained or improved by the washing method.
10. The method of claim 6, wherein redeposition of soil released during the wash cycle, on the textile, is reduced by the washing method.
11. A detergent composition for washing a textile with malodorous compounds or dirt (pigment soil) on the textile, in the presence of DNA on the textile, comprising:
(a) an anionic surfactant;
(b) a protease, cutinase, carbohydrase, cellulose, pectinase, mannanase, arabinose, galactanase, xylanase or an oxidase, but not an amylase and not a lipase; and
(c) a dexoyribonuclease (DNase),
that when contacted with the textile, the detergent composition removes and prevents from sticking to the textile, the malodorous compounds or dirt, better than the same detergent that lacks the DNase,
wherein the detergent composition comprises 10-40 w/w % of the surfactant, 4-50 w/w % of a builder and 0-5 w/w % of a polymer and optionally a filler, solvents and an enzyme stabilizer.
