Abstract

The present invention concerns a detergent comprising a deoxyribonuclease (DNase). The present invention further relates to methods and uses of the detergent comprising a deoxyribonuclease (DNase) for laundering.

First claim

The invention claimed is:

1. A detergent composition comprising:
(a) a polypeptide having deoxyribonuclease activity, wherein the polypeptide has at least 85% sequence identity to a polypeptide selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, and SEQ ID NO: 3; and
(b) at least one surfactant,
wherein the total amount of surfactant(s) in said composition is in the range of 3.6 w/w % to 28.5 w/w %.

2. The detergent composition of claim 1 , wherein the at least one surfactant is selected from the group consisting of anionic surfactants, cationic surfactants and non-ionic surfactants.

3. The detergent composition of claim 2 , wherein the composition comprises at least one anionic surfactant and the amount of said anionic surfactant(s) in said composition is in the range of 2.5 w/w % to 19.6 w/w %.

4. The detergent composition of claim 1 , wherein the at least one surfactant comprises linear alkylbenzene sulfonate (LAS).

5. The detergent composition of claim 4 , wherein the amount of linear alkylbenzene sulfonate (LAS) in said composition is in the range of 1.2 w/w % to 9.6 w/w %.

6. The detergent composition of claim 1 , wherein the at least one surfactant comprises at least one alkyl ethoxysulfate (AEOS).

7. The detergent composition of claim 6 , wherein the amount of said at least one alkyl ethoxysulfate (AEOS) in the composition is in the range of 0.7 w/w % to 5.6 w/w %.

8. The detergent composition of claim 1 , wherein the at least one surfactant comprises at least one non-ionic surfactant and the amount of the non-ionic surfactant(s) in the composition is in the range of 1.1 w/w % to 8.8 w/w %.

9. The detergent composition of claim 8 , wherein the at least one non-ionic surfactant is AEO Biosoft N25-7.

10. The detergent composition of claim 1 , further comprising a builder.

11. The detergent composition of claim 1 , wherein the composition is in a solid form.

12. The detergent composition of claim 1 , wherein the composition is in a liquid form.

13. The detergent composition of claim 4 , wherein the detergent composition comprises a solvent.

14. The detergent composition of claim 1 , wherein the polypeptide having deoxyribonuclease activity is selected from the group consisting of
a polypeptide having at least 90% sequence identity to the mature polypeptide of SEQ ID NO: 1,
a polypeptide having at least 90% sequence identity to the amino acid sequence set forth in SEQ ID NO: 2, and
a polypeptide having at least 90% sequence identity to the amino acid sequence set forth in SEQ ID NO: 3.

15. The detergent composition of claim 1 , wherein the polypeptide having deoxyribonuclease activity is selected from the group consisting of
a polypeptide comprising or consisting of the mature polypeptide of SEQ ID NO: 1,
a polypeptide comprising or consisting of the amino acid sequence set forth in SEQ ID NO: 2, and
a polypeptide comprising or consisting of the amino acid sequence set forth in SEQ ID NO: 3.

16. The detergent composition of claim 1 , wherein the concentration of the polypeptide having deoxyribonuclease activity in a wash dose of the detergent composition is within the range of 0.001 ppm to 100 ppm.

17. The detergent composition of claim 1 , wherein the total amount of surfactant(s) including soap in the composition is in the range of about 5 w/w % to about 20 w/w %.
