Abstract
A perfume composition contains at least 50% by weight of materials which fall into five categories defined by structure, and molecular weight. Amounts of material within each category fall within specified ranges of percentage of the whole composition. Two categories, ethers and salicylates, must be present. At least two of the remaining three categories, which are alcohols, acetate/propionate esters and methyl aryl ketones, must also be present. The compositions enable good levels of deodorant activity to be achieved along with consumer-acceptable fragrance.
Claims26
A perfume composition in which at least 50% by weight of the composition is constituted by at least four of the following five categories:
- a) from 0.2 to 20% of one or more ethers of formula
- R.sup.1 OR.sup.2
- in which the group R.sup.1 and R.sup.2 are connected only through the ether oxygen atom, and are aliphatic or aromatic groups such that the ether has a molecular weight of 150 to 200;
- b) from 5 to 50% of one or more aromatic methyl ketones of general formula ##STR5## in which R.sup.3 is an aromatic group which is unsubstituted or substituted with a benzene, a naphthalene or an indene ring such that the molecular weight of the ketone is from 170 to 300;
- c) from 5 to 50% of one or more alcohols of formula
- R.sup.4 OH
- in which R.sup.4 is an aliphatic group, optionally containing not more than one olefinic double bond, and optionally bearing an aromatic substituent group, such that the molecular weight of the alcohol is in the range 130 to 180;
- d) from 2 to 40% of one or more esters which are acetates or propionates of formula
- CH.sub.3 CO.sub.2 R.sup.5 and C.sub.2 H.sub.5 CO.sub.2 R.sup.5
- in which the group R.sup.5 is an aliphatic group optionally containing not more than one olefinic double bond, and optionally bearing an aromatic substituent group such that the molecular weight of the ester is in the range 180 to 210;
- e) from 2 to 60% of one or more salicylates of general formula ##STR6## in which R is an aliphatic group, optionally containing not more than one olefinic double bond, and optionally bearing an aromatic substituent group, such that the molecular weighty of the salicylate is in the range 190 to 230;
- provided that the categories which are present include:
- (i) both category (a) which is the said ethers and category (b) which is the said aromatic methyl ketones with category (a) then containing from 0.2 to 6% by weight of one or more ethers in which the group R.sup.1 is phenyl or naphthyl, unsubstituted or substituted with alkyl;
- (ii) both category (a) which is the said ethers and category (e) which is the said salicylates;
- or
- (iii) categories (a) which is the said ethers, (b) which is the said aromatic methyl ketones and (e) which is the said salicylates;
- all the above percentages being by weight of the whole perfume compositions.

- or
- (iii) categories (a) which is the said ethers, (b) which is the said aromatic methyl ketones and (e) which is the said salicylates;
- all the above percentages being by weight of the whole perfume composition.
