Abstract

The present invention relates to the use of one or more oxidoreductases in combination with a mediator for the reduction of malodour. Malodour reducing compositions and products comprising such composition are also claimed.

Claims

1. A composition comprising

(i) a laccase obtained from a strain selected from the group consisting of Coprinus, Polyporus and Myceliophthora, and

(ii) a mediator selected from the group consisting of chlorogenic acid, Oolong tea extract, and caffeic acid and esters thereof.

2. The composition of claim 1, wherein the laccase is obtained from a strain of Myceliophthora.

4. The composition of claim 1, further comprising a surfactant.

3. A composition comprising

(i) a peroxidase obtained from a strain of Coprinus, and

(ii) a mediator selected from the group consisting of chlorogenic acid, Oolong tea extract, and caffeic acid and esters thereof.

5. An oral care product comprising

(i) a laccase obtained from a strain selected from the group consisting of Coprinus, Polyporus, and Myceliophthora, and

(ii) a mediator selected from the group consisting of chlorogenic acid, Oolong tea extract, and caffeic acid and esters thereof.

6. The oral care product of claim 5, wherein the laccase is obtained from a strain of Myceliophthora.

7. An oral care product comprising

(i) a peroxidase obtained from a strain of Coprinus, and

(ii) a mediator selected from the group consisting of chlorogenic acid, Oolong tea extract, and caffeic acid and esters thereof.

8. The oral care product of claim 7, wherein the product is toothpaste, dental cream, gel or tooth powder, odontic, mouth washes, pre- or post-brushing rinse formulations, chewing gum, lozenges, or candy.

9. A food product comprising

(i) a laccase obtained from a strain selected from the group consisting of Coprinus, Polyporus, and Myceliophthora, and

(ii) a mediator selected from the group consisting of chlorogenic acid, Oolong tea extract, and caffeic acid and esters thereof.

10. The food product of claim 9, wherein the laccase is obtained from a strain of Myceliophthora.

11. A food product comprising

(i) a peroxidase obtained from a strain of Coprinus, and

(ii) a mediator selected from the group consisting of chlorogenic acid, Oolong tea extract, and caffeic acid and esters thereof.

12. A hygiene product comprising

(i) a laccase obtained from a strain selected from the group consisting of Coprinus, Polyporus, and Myceliophthora, and

(ii) a mediator selected from the group consisting of chlorogenic acid, Oolong tea extract, and caffeic acid and esters thereof.

13. The hygiene product of claim 12, wherein the laccase is obtained from a strain of Myceliophthora.

15. The hygiene product of claim 12, wherein the product is diapers, adult incontinence products, training pants, feminine napkins, or tampons.

14. A hygiene product comprising

(i) a peroxidase obtained from a strain of Coprinus, and

(ii) a mediator selected from the group consisting of chlorogenic acid, Oolong tea extract, and caffeic acid and esters thereof.

16. A toiletry product comprising

(i) a laccase selected from a strain selected from the group consisting of Coprinus, Polyporus, and Myceliophthora, and

(ii) a mediator selected from the group consisting of chlorogenic acid, Oolong tea extract, and caffeic acid and esters thereof.

17. The toiletry product of claim 16, wherein the laccase is obtained from a strain of Myceliophthora.

19. The toiletry product of claim 16, wherein the product is a soap bar.

18. A toiletry product comprising

(i) a peroxidase obtained from a strain of Coprinus, and

(ii) a mediator selected from the group consisting of chlorogenic acid, Oolong tea extract, and caffeic acid and esters thereof.
