Abstract: The use of specific perfume ingredients, e.g. tricyclodecenyl allyl ether, to repel insects. The perfume ingredients may be used in a composition comprising from 0.1 to 40 percent by weight of one or more of the perfume ingredients. Preferably at least one of the perfume ingredients has a hydrophobicity such that the common logarithm of the octanol-water partition coefficient, log P, of the perfume ingredient is in the range 1.0 to 6.0.

Abstract: A device for dispensing a liquid in a carrier fluid flow comprises a container (10) for the liquid, into which a pressure flow of carrier fluid is driven. A liquid conduit (20) within the container has an outlet (22) in the path of the carrier fluid flow into the container so that liquid is taken up and is carried with the flow, through an outlet (26) from the container. The container can be formed by a disposable capsule that is replaceably inserted into the device.

Abstract: Odors are evaluated in relation to a target or priming stimulus by testing a subject by presenting the subject with one or more adors under different conditions, at least some being in the presence of one or more targets or priming stimuli; subsequently testing recognition of said one or more adors by the subject and monitoring implicit ador memory; and evaluating the results of implicit memory for ador/target combinations presented to the subject in the first stage of testing. Evaluation of the results of implicit memory for ador/target combinations presented to the subject provides a measure of the degree of association between the ador and target in a particular ador/target combination. These measures can be compared and used as a basis for ador selection.

Abstract: A method of odor selection for selecting an odor to match a visual or auditory target stimulus, comprising evaluating a number of odor/target stimulus combinations by testing a subject by presenting the subject with one or more odors under different conditions, at least some conditions being in the presence of one or more target stimuli monitoring brain activity of the subject and evaluating the monitored brain activity in relation to odor/target stimulus combinations presented to the subject and selecting the odor/target stimulus combination or combinations indicated as having the greatest degree of association.

Abstract: A perfumed product containing an antibacterial agent and a perfume material is prepared. The perfumed product can contain triclosan as the antibacterial agent and a mixture of perfume materials such as Amberlyn Super PM 577, clover leaf, dihydro myrcenol, phenyl propyl alcohol and terpineol alpha.

Abstract: The invention relates to laundry detergents containing lipase and new perfumes and to the new perfumes themselves. Such new perfumes counteract residual malodors of lipase treated laundry. They comprise at least 25% by weight of one or more fragrance materials chosen from: aliphatic ketones with m(olecular) w(eight) between 200 and 350 A(tomic) M(ass) U(nits), aromatic ketones with mw between 150 and 350 AMU, aliphatic aldehydes with mw between 160 and 350 AMU, aromatic aldehydes with mw between 130 and 350 AMU, nitriles with mw between 150 and 350 AMU, condensation products of aldehydes and amines with mw between 190 and 350 AMU, macrocyclic lactones with mw below 350 AMU and aromatic nitromusks, and less than 50% by weight of esters from fatty acids with 1-7 carbon atoms. Preferably they contain more than 30% of the specified fragrance materials and less than 30% of the esters.

Abstract: A substrate (e.g. skin of unknown type, fabric, or hard surfaces) is characterized by analyzing chemicals emanating from the substrate or from a substance (e.g. a test formulation comprising a mixture of volatile chemicals) applied to the substrate. Analysis is preferably done using a volatile chemicals sensor, desirably a sensor comprising an array of conducting polymer sensors. The chemical analysis data obtained in this way may be statistically analyzed, e.g. by Euclidian distance mapping or principal component analysis, for ease of handling. Having characterized a surface in this way, products, e.g. cosmetic and cleaning products, may be formulated for optimized performance on that substrate.

Abstract: The invention concerns perfumed, free flowing concentrated laundry detergent powders (concentrates), having a ratio of total solid constituents to total liquid constituents of less than 30:1, wherein the perfume is sorbed onto carrier particles which release at least 60% w/w/ of the perfume in the Perfume Release Test and which are inert as defined by the Perfume Stability Test. The invention also concerns perfume-on-carrier systems designed for perfuming free flowing concentrated laundry detergent powders. Preferably the carrier particles are inorganic and have a perfume content of at least 25% w/w.

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 flavour to be added to the triglyceride or derivative thereof without distorting their organoleptic effect.

Abstract: The invention concerns perfumed underarm hygiene products containing perfume encapsulated in a film forming encapsulation material showing improved re-encapsulating properties as evidenced by the "perfume re-encapsulation test. The underarm hygiene products preferably contain 0.05-10% w/w of perfume encapsulates. The perfume encapsulates used contain preferably 15-65% w/w of perfume. The underarm hygiene products may additionally contain a quantity of neat perfume.

Abstract: The invention is concerned with a process for counteracting smoke malodour wherein enclosed air spaces wherein smoke maladour is present, or substrates on which smoke malodour has deposited are brought in contact with one or more perfumery aldehydes of the class I according to general structure, wherein R1 and R2 each may be: hydrogen, alkyl, hydroxyl or alkoxy, or together may be methylenedioxy or with a perfume containing such aldehydes. Preferably the perfume also contains one or more perfumery aldehydes of class according to general structure, wherein R1 is a phenyl ring optionally substituted with an alkyl group, R2 represents hydrogen or both R2 taken together represent a double bond, and R3 is hydrogen or an alkyl chain with 1 to 6 carbon atoms. The smoke malodour counteracting perfumes preferably contain at least 3.5% w/w of class I aldehydes and at least 10% w/w of class II aldehydes.
