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.

Perfume compositions

Compositions of fragrance materials having an Odour Intensity Index of less than 110, and a Malodour Reduction Value of at least 0.25 or an Odour Reduction Value of at least 0.25, can be used as fragrance compositions in detergent powders, detergent liquids, soap or detergent bars or pastes, fabric-conditioning compositions in liquid or solid form, or personal body deodorant compositions, to confer deodorant effects in use even though they have in themselves a low or imperceptible level of fragrance (Odour Intensity Index).

Fragrance compositions and their use in detergent products

A fabric conditioning product which may be used during the rinsing or tumble drying of fabrics after washing, contains a perfume composition which contains specified ketones and salicylates. The perfumes inhibit development of human body malodour on the fabrics when worn and the combination of specified materials makes it possible to avoid inclusion of individual components with powerful, unacceptable odors.
