  • Patent number: 6523722
    Abstract: A sprayhead for example for an aerosol or pumpspray container comprises a support, a fluid outlet mounted on the support, a passageway connected to the fluid outlet at a first end and connectable to a fluid source at a second end, the passageway being movable between a first non-operative position and a second position in which, in use, it is connected to a fluid source such that fluid can pass through the passageway to the fluid outlet, a member secured relative to the support, the member being movable between a non-operative position and a further position in which it allows the passageway to attain its second position, and a lock selectively operable to lock the member in its first position, thereby preventing the member from urging the passageway to its second position unless the lock is released.

  • Patent number: 6509010
    Abstract: A cosmetic method of reducing the acidity of sweat excreted from human eccrine glands, said method comprising the topical application of a V-ATPase inhibitor to the skin in the vicinity of the eccrine glands. Said method may result in a range of benefits, including enhanced appreciation of topically-applied perfume and enhanced efficacy of topically-applied antiperspirant salt. Cosmetic products and compositions comprising a V-ATPase inhibitor and selected other components are also claimed.

  • Patent number: 6503492
    Abstract: Deodorant and antiperspirant compositions comprising an aluminium or aluminium-zirconium active can suffer from perceived irritancy when applied topically, which is generally manifested as an itch sensation. This irritancy can be ameliorated or overcome by incorporating within the composition a cannabanoid receptor (CBR) activating agent, and especially an amount selected in the range of from 0.25 to 10 wt %.

  • Patent number: 6458345
    Abstract: The sensory attributes and/or visibility of deposits of wax-structured antiperspirant or deodorant sticks in the form of emulsions can vary significantly depending on the formulation employed. A particularly beneficial balance of attributes is obtained in emulsion sticks by employing a composition comprising a continuous phase which comprises from 10 to 35% volatile silicone oil, and from 5 to 15% non-volatile hydrophobic oil, from 40 to 75% of ta disperse aqueous phase which contains from 1 to 35% of an antiperspirant or deodorant active, from 7 to 25% of a wax structurant, from 0.1 to 10% of an emulsifier, and preferably contains up to 5% insoluble particulate materials, %s being by weight based on the composition.

  • Patent number: 6458344
    Abstract: A cosmetic composition preferably an antiperspirant composition, in solid or soft-solid form has a continuous phase which contains a water-immiscible liquid carrier and also contains a structurant which is partially or fully esterified cellobiose of the formula wherein each Z is independently hydrogen or an acyl group of the formula where R denotes a hydrocarbyl group containing from 4 to 22 carbon atoms. Not more than half of the Z groups are hydrogen.

  • Patent number: 6455056
    Abstract: A cosmetic composition contains a water-immiscible carrier liquid and a structurant therefor which is effective to gel the composition upon cooling from a temperature at which the structurant is a mobile solution in the carrier liquid. The carrier liquid may serve as a continuous phase in which a solid or liquid disperse phase is suspended. The structurant is a fully or partially esterified saccharide which contains no more than eight monosaccharide residues and has an enthalpy of gelation in the carrier liquid with a magnitude of at least 45 kJ/mole. This minimum enthalpy of gelation facilitates processing at conveniently accessible temperatures and promotes stability.

  • Patent number: 6426060
    Abstract: A cosmetic composition is a structured emulsion of a continuous phase containing water-immiscible liquid carrier plus a structurant, and a disperse phase which is a solution of antiperspirant active in a more polar, probably aqueous, solvent. The structurant is a material which forms a network of fibers in the continuous phase, thereby gelling it. The structurant has an enthalpy of gelation in the carrier liquid or a test liquid with a magnitude of at least 30 kJ/mole. This minimum enthalpy of gelation facilitates processing at conveniently accessible temperatures and promotes stability.
