Abstract

A perfume composition contains at least 15% by weight one or more defined aldehydes, and at least 30% by weight of at least one of five defined categories of hydroxylic materials, ketones, ethers, esters and nitriles. The perfume composition exhibits a deodorant effect, is particularly good at reducing sulphurous malodors, and is suitable for use in deodorant products, personal products and laundry treatment products.

Dependent claims

A perfume composition comprising:

(1) at least 15% by weight of the perfume composition of one or more aldehydes of general formula:
R1CHO
having an octanol-water partition coefficient within the range of 2.0 to 4.4 (in logarithmic form), and wherein the group R1 is a hydrocarbyl radical which may comprise aromatic or aliphatic groups, and mixtures thereof, and which may be cyclic or acyclic, straight chained or branched, and optionally substituted with other groups, with the proviso that at least 1% by weight of the perfume composition comprises aliphatic aldehydes of this general formula, and
(2) at least 30% by weight of the perfume composition of at least two of the following five categories of perfumery ingredients;
a) at least 2.0% by weight of the perfume composition of one or more hydroxylic materials of general formula:
R1OH
having an octanol-water partition coefficient within the range of 2.5 to 3.6 (in logarithmic form), and wherein the group R1 is a hydrocarbyl radical containing no more than one olefinic double bond, and comprising aromatic or aliphatic groups, and mixtures thereof, and which may be cyclic or acyclic, straight chained or branched, and optionally substituted with other groups,
b) at least 2.0% by weight of the perfume composition of one or more ketones of general formula:
R1CO R2
having an octanol-water partition coefficient within the range of 3.0 to 4.1 (in logarithmic form), and wherein the groups R1 and R2 are independently hydrocarbyl radicals which may comprise aromatic or aliphatic groups, and mixtures thereof, and may be cyclic or acyclic, straight or branched, and optionally substituted with other groups,
c) at least 2.0% by weight of the perfume composition of one or more ethers of general formula:
R1O R2
having an octanol-water partition coefficient within the range 3.0 to 4.0 (in logarithmic form), and wherein the groups R1 and R2 are independently hydrocarbyl radicals which may comprise aliphatic or aromatic groups, and mixtures thereof, and which may be straight or branched and optionally substituted with other groups, with the proviso that at least one of R1 and R2 comprises an olefinic double bond,
d) at least 2.0% by weight of the perfume composition of one or more esters of general formula:
R1CO2R2
having an octanol-water partition coefficient within the range 2.6 to 4.3 (in logarithmic form), and wherein the groups R1 and R2 are independently hydrocarbyl radicals which may comprise saturated aliphatic or aromatic groups, and mixtures thereof, and which may be straight chained or branched, cyclic or acyclic, and optionally substituted with other groups, and
e) at least 2.0% by weight of the perfume composition of one or more nitriles of general formula:
R1CN
having an octanol-water partition coefficient within the range 3.0 to 4.4 (in logarithmic form), and wherein the groups R1 is a hydrocarbyl radical comprising an olefinic double bond, which may comprise aliphatic or aromatic groups, and mixtures thereof, and which may be straight chained or branched, cyclic or acyclic and optionally substituted with other groups, said perfume composition comprising 2-methyl-3-(4′-(1″-methylethyl)phenyl)propanal, acetyl di-isoamylene and 2-tert-butylcyclohexyl acetate as at least some of said aldehyde (1), ketone 2b) and ester 2d), respectively.
