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.
