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.

First claim

What is claimed:

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:
