Abstract

Unscented and low scented malodor control compositions are provided. The malodor control compositions are suitable for a variety of applications, including use on plastic films or in fabric and air freshening products.

Claims

1. A malodor control composition comprising:

a perfume mixture comprising methyl palmitate, vetivert acetate, and cedryl methyl ether, and optionally comprising farnesol, undecylenic aldehyde, florhydral, helional, and vertofix couer for reducing malodors.

2. The malodor control composition of claim 1 wherein said perfume mixture further comprises at least one volatile aldehyde selected from the group consisting of floral super, 2-ethoxy Benzylaldehyde, 2-isopropyl-5-methyl-2-hexenal, 5-methyl Furfural, 5-methyl-thiophene-carboxaldehyde, p-anisaldehyde, Benzylaldehyde, Cinnamic aldehyde, Decyl aldehyde, Ligustral, Lyral, Melonal, o-anisaldehyde, P.T. Bucinal, Thiophene carboxaldehyde, trans-4-Decenal, trans 2,4-Nonadienal, Undecyl aldehyde, and mixtures thereof.

3. The malodor control composition of claim 1 wherein said perfume mixture comprises about 30% to about 100% methyl palmitate, vetivert acetate, and cedryl methyl ether for reducing malodors.

4. The malodor control composition of claim 1 wherein said perfume mixture further comprises a volatile aldehyde mixture selected from the group consisting of:

5. The malodor control composition of claim 1 wherein said perfume mixture further comprises about 1% to about 10% of Accord A, by weight of said perfume mixture.

6. The malodor control composition of claim 1 wherein said perfume mixture is present in an amount from about 50% to about 100%, by weight of said malodor control composition.

7. The malodor control composition of claim 1 further comprising an acid catalyst present in an amount of about 0.1% to about 1.5%, by weight of said malodor control composition.

8. The malodor control composition of claim 7 wherein said acid catalyst has a vapor pressure of about 0.01 to about 2 torr at 25°

C.

9. The malodor control composition of claim 7 wherein said acid catalyst is a carboxylic acid.

10. The malodor control composition of claim 9 wherein said acid catalyst is 5-methyl thiophene carboxylic acid.

11. The malodor control composition of claim 1 wherein said composition has a pH of about 4 to about 6.5.

12. The malodor control composition of claim 1 further comprising an ingredient selected from the group consisting of:

odor masking agents, odor blocking agents, diluents, and mixtures thereof.

13. A plastic film comprising a perfume mixture comprising at least 2 perfume ingredients selected from the group consisting of:

undecylenic aldehyde, methyl palmitate, vetivert acetate, farnesol, and mixtures thereof, wherein said perfume mixture reduces malodors in the air.
