Abstract: A method for reducing or preventing body malodour by topically applying to human skin perfumery materials capable of inhibiting the production of malodorous metabolites caused by micro-organisms comprising corynebacteria. The perfumery materials are capable of inactivating corynebacteria capable of catabolising fatty acids.

Abstract: A perfume composition contains at least 30% by weight of perfume components having a minimum inhibitory concentration (MIC) for coryneform bacteria of greater than 0.1%. The composition can be used in deodorant products to reduce body malodour sub-lethally, i.e. without significantly affecting the numbers of bacteria present on the skin surface.

Abstract: A method of reducing or preventing body malodour by topically applying to human skin perfume components capable of inhibiting the producation of odoriferous steroids by microorganisms on the skin. The perfume components are capable of inhibiting bacterial 4-ene reductase and/or 5&agr;-reductase.

Abstract: A method for reducing or preventing body malodour by topically applying to human skin a perfume component capable of selectively increasing the population of naturally occurring deodorising micro-organisms on the surface of the skin. The perfume component is preferably capable of inhibiting lysozyme.

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.

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.

Abstract: 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).

Abstract: An encapsulation process employs an aqueous dispersion of silica having a particle size not substantially greater than 100 nm. An emulsion is formed by high shear mixing of the silica dispersion with the material to be encapsulated and the emulsion is gelled. The process allows hydrophobic materials to be encapsulated in structures which have a high loading of the material and a good degree of imperviousness in the presence of other materials such as surfactants and mineral oils. Using the process, hydrophobic materials such as flavours, fragrances and cosmetic ingredients can be encapsulated for delayed release in a wide variety of products.

Abstract: 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.

Abstract: The invention concerns clear o/w microemulsions comprising a perfume oil, an aqueous phase and one or more surfactants with HLB between 9 and 18, and co-surfactants of which at least 0.5% of ionic co-surfactant. The weight ratio of perfume oil to total surfactant is between 0.85 and 2.5, and preferably above 1. The quantity of perfume oil is 0.01-40% w/w, preferably below 35%, of the microemulsion and the quantity of water at least 40% w/w, preferably at least 50%. The microemulsions comprise less than 10% preferably less than 5%, of alcohol. The surfactants are preferably of the nonionic type.The microemulsions are very suitable for perfuming purposes where the amount of organic solvents should preferably be kept to a minimum, such as for perfuming skin or hair.The invention also concerns surfactant/perfume mixtures suitable for preparing the clear o/w microemulsions.

Abstract: The invention concerns a process for incorporating a perfume into a personal product, wherein the perfume is first combined with one or more non-ionic emulsifiers and an aqueous phase to form a structured emulsion containing liquid crystal structures, which surround the dispersed perfume, and thereafter this structured emulsion is dispersed into a personal product base. The invention also concerns the personal products thus obtained and the structured emulsions used in the process. The structured emulsions comprise 1-30 % by weight of one or more non-ionic emulsifiers, 1-50% by weight of a perfume and 20-98% by weight of an aqueous phase. Preferably low shear mixing is used in preparing the emulsions.

Abstract: The invention concerns a process for incorporating a perfume into a detergent product, wherein the perfume is first combined with one or more non-ionic emulsifiers and an aqueous phase to form a structured emulsion containing liquid crystal structures, which surround the dispersed perfume, and thereafter this structured emulsion is dispersed into a detergent composition. The invention also concerns the detergent products thus obtained. The structured emulsion comprises 1-30% by weight of non-ionic emulsifiers, 1-50% by weight of a perfume and 20-98% by weight of an aqueous phase. The detergent product comprises at least 4% by weight of surfactant.

Abstract: The invention concerns a method of reducing the organoleptic effect of undesirable aldehydic components in a triglyceride or derivative thereof by addition of a reaction product of an amine and an organoleptically acceptable aldehyde. The triglyceride may be a food or food component such as an edible fat or a surface active agent such as a detergent. The reaction product may be incorporated in the perfume or flavor to be added to the triglyceride or derivative thereof without distorting their organoleptic effect.
