  • Patent number: 7854356
    Abstract: A spray cap, also known as an actuator overcap for an aerosol container, has an acoustic seal between the actuator button and the overcap. This acoustic seal is formed by a set of matching sealing lips on the actuator button and also on the overcap, such that they are both oriented horizontally. At rest, the sealing lip of the actuator button rests above the sealing lip of the overcap, but during actuation, the sealing lip of the actuator button deforms the sealing lip of the overcap, which both forms an acoustic seal during actuation and creates the force to return the sealing lip of the actuator button back to its original position after actuation is complete.

  • Patent number: 7854234
    Abstract: A method of setting up, caring for and later removing a temporary rasta hairstyle is described. This method includes one or more of the following steps: applying a roughness-increasing substance to the hair to roughen the hair, applying an adherence-increasing substance to the hair to increase adherence of hairs to each other, and subsequently setting up the temporary rasta hairstyle by intertwining hair strandwise. The cleaning of the temporary rasta hairstyle occurs preferably using a concave sponge, without disturbing the temporary rasta hairstyle. To again remove the temporary rasta hairstyle a composition that increases the combability is applied to the hair and the rasta strands are opened and unwound or untwisted. Multi-component kits and compositions for performing the method are also described.

  • Patent number: 7758347
    Abstract: The hair color simulation system for simulating a dyed hair color that results from dyeing hair with a mixture of two hair color preparations includes a base screen with a first through fifth layers and an intermediate layer. The first through fifth layers and the intermediate layer are superimposed over one another so as to display a simulated hair color that is produced when the first hair line, the second hair line, the colors of the two hair color preparations and the original hair color are displayed on the layers with respective transparencies and superimposed over each other. The RGB values of the superimposed colors produced by the two hair color preparations and the original hair color are stored in data storage sections. Input sections receive choices of the two hair color preparations and a mixing ratio for the simulation.

  • Patent number: 7670391
    Abstract: The dust-free coated dye-containing pellet is a granulated carrier material that is encapsulated with a dye-containing coating material. The dye-containing coating material contains a mixture of a water-soluble or water-dispersible film-former with at least one direct dye and/or at least one oxidation dye precursor. Preferred carrier materials include dextrose, oligosaccharides and cellulose compounds. The dust-free coated dye-containing pellet is preferably made by granulating the carrier material together with optional antioxidants and auxiliary agents, heating the resulting granulate at no more than 34° C., subsequently coating the granulate by spraying it with a solution or dispersion of the coating material and optionally drying as needed.

  • Patent number: 7648535
    Abstract: The agent for coloring keratin fibers is free of chemical oxidants, is in the form of an aqueous or aqueous-alcoholic dye-containing preparation, and contains a combination of oxidation dyes and at least three direct dyes. The agent is characterized by a quantitative ratio of oxidation dyes to direct dyes equal to 5:1 to 0.5:1. A method of dyeing hair is described in which the agent is applied to hair and allowed to act on the hair for an acting time of 5 to 60 minutes without addition of chemical oxidants, so that air oxidation provides a uniform and stable coloration of the hair.
