  • Patent number: 6358493
    Abstract: Gasified particles for cosmetic treatments, particularly hair treatments, are described. The gasified particles contain at least one gas enclosed in a solid enveloping material. The enveloping material is selected so that the gas is released on contact of the enveloping material with water or moisture. The release of the gas can be accompanied by a detectable acoustic effect (pop effect). The hair treatment composition also can provide a hair fixing effect. Furthermore an instant gel preparation is described substantially comprising a mixture of dry substances, which contains at least one gel former and at least one solid substance producing a detectable acoustic effect on contact with moisture, especially gasified particles. The gasified particles are used as acoustic indicators for the readiness of the instant preparation after liquid addition.

  • Patent number: 6328950
    Abstract: The pigment-containing foamable gel for temporarily coloring the hair contains from 35 to 98 percent by weight water; one or more gel-forming thickener that imparts a yield point to the composition; at least one pigment; at least one film-forming, hair-fixing polymer; at least one foam-producing surfactant and at least one propellant, in combination with a suitable aerosol package and a foam-forming device for foaming the gel. The concentration of the thickener or thickeners in the gel is selected so that, on the one hand, the viscosity of the gel is sufficiently reduced so that foaming of the gel is possible and, on the other hand, the yield point is at least large enough so that settling of the pigment is prevented. The easily foamable composition has a hair-fixing effect and temporarily colors the hair, providing a high color brilliance and lustrous appearance. The composition is washable from the hair at will and the color of the hair provided by it has good fastness to rubbing.

  • Patent number: 6247586
    Abstract: In a two-component container (1) a connection is formed between two chambers (6, 7) by ejecting a sealing plug (5). By screwing one container (3) into a thread (4) connected to another container (2) the sealing plug (5) which is provided with two stoppers (12, 13) is pressed out of its retaining members (14, 15). Sealing takes place in a reliable manner by two separate stoppers (12, 13) of the sealing plug (5). When the container (3) is screwed in, first the lower stopper (13) is ejected by the upper stopper (12) and then the upper stopper (12) is ejected by an ejection member (22). The two-component container (1) is suitable for holding peroxide and hair dye separately. After it has been ejected, the sealing plug (5) assists in the mixing of the said two components.
