  • Patent number: 6410001
    Abstract: Compositions for application to human skin have a continuous phase which contains water-immiscible oil structured by incorporation of a compound of formula in which Y and Y1 are each independently —CH2 or >CO Q and Q1 are each independently a hydrocarbyl group of at least 6 carbon atoms and m is from 2 to 4. The composition may be an antiperspirant containing suspended particulate antiperspirant active or containing a dispersed phase in which antiperspirant active is dissolved in water or water-immiscible solvent.

  • Patent number: 6410002
    Abstract: A clear emulsion and gel-type cosmetic composition, and in particular to an antiperspirant and/or deodorant composition which comprises a water-in-oil emulsion comprising: a) about 65% to about 75% of an aqueous solution of an effective amount of antiperspirant active; b) about 25% to about 35% of an oil phase consisting of silicones, emollients and a silicone emulsifying agent, and comprising at least one volatile silicone, at least one non-volatile ester or at least one nonvolatile silicone, and wherein at least one oil phase soluble ingredient has a refractive index of about 1.40 to about 1.45; c) about 0.01 to about 8.5% of a coupling agent; and d) at least one polymeric ethylene oxide glycol adduct which component raises the refractive index of said aqueous solution, and optionally another water soluble, non-simple glycol component which raises the refractive index of said aqueous solution; wherein said composition is essentially free of glycols and low and middle chain alcohols; is described.

  • Patent number: 6391291
    Abstract: A firm solid antiperspirant composition having a continuous phase comprising water-immiscible liquid containing i) one or more gelating structurant materials which form a network of fibres within the liquid, and ii) a polymeric thickener which has an organic polymer backbone containing at least five monomer repeat units, which polymer has the ability to increase the viscosity of the water-immiscible liquid in the absence of the gelating structurant materials; and iii) an antiperspirant active dispersed in the continuous phase, said composition being free from or containing less than 3% by weight of a fatty alcohol that is solid at 20° C.

  • Patent number: 6387358
    Abstract: Soft solid antiperspirant formulations in which a particulate antiperspirant active material is suspended in a continuous phase containing a water-immiscible liquid which is structured by specified proportions of an organic polymeric thickener and a second structurant selected from fibre-forming structurants and waxes (often other than fatty alcohols) or a mixture of both. Such soft solid formulations avoid or minimise problems inherent in production of many published formulations such as sensitivity to small changes in concentration of the structurant.

  • Patent number: 6361766
    Abstract: Anhydrous antiperspirant formulations in which a particulate antiperspirant active is suspended in a carrier fluid can result in significant visible deposits when applied to skin or when transferred onto clothing. Anhydrous antiperspirant suspension sticks which exhibit very low visible deposits are obtainable by employing a carrier fluid in which at least 45% and preferably at least 60% of its weight comprises an oxygen-containing emollient oil having a refractive index of at least 1.465, in conjunction with structurant comprises a wax or a non-polymeric fiber-forming gellant, excluding certain gellants or gellant combinations. Preferred emollient oils include alkyl benzoates and alkylphenylsiloxanes. The waxes can even comprise fatty alcohols.

  • Patent number: 6361765
    Abstract: Antiperspirant compositions herein comprise an antiperspirant active, together with a carrier and a structurant for the carrier which comprises an organic wax having a melting point of from 40 to 90° C. of which at least 60% of the weight of the wax is provided by at least one aliphatic ester satisfying the formula: CH3—(CH2)n—CO—(CH2)m—CH3 in which n is from 9 to 39 and m is from 0 to 35 to form a solid or a soft solid. The compositions can be anhydrous, in the form of a suspension of antiperspirant active, or can comprise aqueous emulsions. The formulations structured by the selected waxes provide lower visible deposits on topical application compared with conventional wax-structured formulations and the waxes are effective at structuring/thickening at a proportion below that in conventional wax-structured formulations.
