  • Patent number: 6589509
    Abstract: The product for hair treatment includes a transparent pressure-resistant aerosol container and a device for making foam from an effective-ingredient containing composition contained in the aerosol container. The effective-ingredient containing composition contained in the transparent aerosol container has two clearly distinguishable liquid phases with a sharply distinct phase boundary. The two liquid phases consist of a hydrophilic phase and a hydrophobic phase. The hydrophilic phase includes water or a solvent system containing water and a water-soluble organic solvent, at least one cationic or cationically-active hair care ingredient and at least one organic or inorganic salt. The hydrophobic phase contains a water-insoluble, liquefied propellant gas and at least one water-insoluble, hydrophobic, oily or fatty substance dissolved in the liquefied propellant gas.

  • Patent number: 6589510
    Abstract: A hair treatment product and method for imparting volume to a hairdo or for strengthening the hair shafts of the hairdo is provided. The hair treatment product is a pressure-resistant aerosol container containing a composition, which forms fast-breaking foam on a section of the hairdo including the hair shafts by means of a spraying head having a comparatively narrow spraying angle. The composition in the aerosol container includes at least 60 percent by weight of water; from 1 to 30 percent by weight of C1- to C5-monovalent alcohol as a foam-breaking agent; from 0.01 to 5 percent by weight of a foam-forming surfactant; from 0.1 to 20 percent by weight of at least one hair-fixing polymer; and an aerosol propellant.

  • Patent number: 6582679
    Abstract: The wax product for treating or setting up a hairstyle or hairdo includes a composition containing at least one wax or wax-like substance, at least one non-volatile liquid hydrophobic oil and at least one volatile or easily volatilized hydrophobic substance that is a liquid or gas at room temperature. Because of the presence of the volatile substance in the composition a soft wax easily worked in the hair is obtained when the composition is applied to the hair. This soft wax hardens on the hair when the volatile ingredients evaporate. When the composition includes a propellant gas a wax with a larger surface area (wax snow) is produced, which is likewise easily worked into the hair and very effectively fixes or sets the hair.

  • Patent number: 6558433
    Abstract: The method of dyeing keratin fibers includes the steps of providing an oxidation dye precursor composition containing from 0.01 to 10 percent by weight of a total amount of at least one coupler compound and at least one developer compound, mixing the oxidation dye precursor composition with an oxidizing agent and applying the resulting mixture to the keratin fibers. The oxidation dye precursor composition is characterized by containing 1,4-diamino-2-methoxymethylbenzene, or a physiologically compatible salt thereof, either alone as sole developer compound, or in combination with other known developer compounds. The oxidation dye precursor composition can also contain at least one direct-dyeing dye compound and conventional cosmetic additive ingredients.

  • Patent number: 6506501
    Abstract: The permanent shaping method avoids overcurling of hair tips. Prior to performing the permanent shaping of the hair, the hair tips are protected by wrapping the hair tips with an impregnated foil and then performing the permanent shaping of the hair. The foil is an impregnated hair-tip paper that has been treated with an aqueous preparation that provides superior permanent shaping results. This aqueous preparation contains water, from 20 to 70 percent by weight of at least one lipophilic substance; from 1 to 25 percent by weight of at least one emulsifier and from 0.5 to 15 percent by weight of at least one organic acid. An impregnated foil made from silk or rice paper is also described.

  • Patent number: 6068900
    Abstract: A plastic container has a high resistance to chemical attack and is made by a method including extruding and inflating a tube in a single operation by a coextrusion blow molding process to form a hollow plastic body. The tube consists of an outer layer made of glycol-modified polyethylene terephthalate (PETG) and an inner layer made of polyethylene terephthalate (PET), polyethylene naphthalate (PEN) or a mixture thereof. Selection of the foregoing materials and layers allows the plastic body for the container to be made in a single operation by coextrusion blow molding.
