Abstract: Fragrance compositions containing volatile organic acids may be used to eliminate amine malodors from an air-space. The acids are characterised by having (i) a pKa at 250C of from 3 to 5, preferably a pKa of from 3.5 to 4.5; (ii) a vapour pressure, at 250C, greater than 0.1 ?m Hg, preferably greater than 1 ?m Hg, even more preferably between 1 and 100 ?m Hg. Preferred acids are cinnamic acid, phenylacetic acid, benzoic acid and 2-pentycyclopropanecarboxylic acid, and combinations thereof, present at levels of at least 0.2% by weight, more preferably 0.5% by weight in the fragrance.

Abstract: The present invention relates to a method of preventing and/or reducing malodours in an environment, comprising use of an encapsulated perfume, the perfume being encapsulated in capsules comprising perfume in an amount greater than 4% by weight of capsule, and an anionic gum, the method comprising the step of placing the capsules in gaseous contact with the environment, such that perfume released from the capsules prevents and/or reduces malodour in the environment. The capsules typically demonstrate efficient and consistent perfume release over an extended period of time e.g. up to about 85 days and conveniently provide a visual indication of expiration by a change in colour an size during use until a defined end point, when capsule life is exhausted. Also disclosed is a capsule including an emulsifying agent selected from non-ionic surfactants and/or anionic surfactants.

Abstract: Novel compounds of use in perfumery are obtained by performing a Prins reaction on isolongifolene. They include novel primary and secondary alcohols, their esters and the corresponding aldehydes and ketones.

Abstract: Compounds having the formula ##STR1## wherein R is an alkyl group having from 1 to 4 carbon atoms are produced by the condensation of the appropriate alkoxylated epoxide with diethyl malonate. The unsaturated compound is formed by the dealkoxylation of an alkoxylated compound. These compounds have attractive fruity-floral type odors and are useful as ingredients of compounded perfumery compositions. The invention also includes perfumery compositions containing at least one of said compounds.

Abstract: A compounded perfumery composition comprising component A and component B, component B being from 0.1 to 95% by weight based on the weight of said compounded perfumery composition. Component B comprises at least one compound of the formula wherein R is at least one group selected from methyl, ethyl, propyl, iso-propyl, n-butyl, sec-butyl, tert-butyl, pentyl or hexyl.
