  • Patent number: 6436383
    Abstract: The conditioning performance of small particle size emulsified silicone in a surfactant-based shampoo composition can be significantly boosted by the inclusion in the shampoo composition of an amino functionalised silicone. Accordingly, the invention provides an aqueous shampoo composition comprising, in addition to water: i) at least one surfactant chosen from anionic, nonionic, zwitterionic or amphoteric surfactants or mixtures thereof; ii) an amino functionalised silicone; and iii) emulsified particles of an insoluble, non-amino functionalised silicone, in which the average silicone particle size of the emulsified non-amino functional silicone in the shampoo composition is less than 2 microns.

  • Patent number: 6432393
    Abstract: The invention relates to aqueous hair care compositions including conditioners, shampoos, and mousses. The invention also relates to methods of treating hair, and more particularly to treating hair with aqueous hair care compositions which contain one or more elastomeric resinous materials. These materials when tested at the same concentration that could be incorporated into a product exhibit a G′ modulus between 1×102 and 1×105 dynes/cm2. Furthermore these resins when mixed with a hydrophilic or hydrophobic diluent at a ratio of 1:95 to 95:1% and this mixture then incorporated into an aqueous emulsion in the range of 0.1 to 10% have been demonstrated to deliver a consumer perceptible increase in hair body without sacrificing conditioning attributes.

  • Patent number: 6398082
    Abstract: In the present invention, an actuating mechanism for a hand held canister is provided in which a slider is moveable by finger pressure from a valve-disengaged position into a valve-engagable position and a concealed spring returns the slider to a valve-disengaged position when finger pressure is removed. The spring is preferably molded with the slider, projects through a slit in the over-cap of the canister and acts in a vertical plane against a stop depending from the over-cap. It is energised when the slider is moved into the valve engagable position. The slider is preferably releasably locked in the valve disengaged position.
