Abstract: In order to seal a spray cap acoustically, a cap 7 with a button 6 is provided with an elastic connection 49 between the button 6 and the cap 7 so as to form an acoustic seal 49 of the cap 7. The seal 49 is designed as a folded arrangement.

Abstract: The invention relates to the use of fluorescent perylene compounds for the treatment of human hair, in particular for improving the shine of hair, and to corresponding hair-treatment compositions. Preferred perylene compounds are N-alkyl-substituted 3,4:9,10-bis(dicarboximide)perylenes.

Abstract: A cosmetic preparation in gel form is described which contains undissolved, water-swollen polymer particles and at the interface with gaseous substances forms reversibly a grainy, uneven, light-scattering surface and at the interface with solids forms reversibly a smooth, level, non-light-scattering surface. Preferred gel formers are superabsorbing polymers. A preferred use is the hair-end protection in permanent wave treatment.

Abstract: A device (1) for a hair dryer (2), having a fan (3) and a heater (4) for generating a central hot-air stream (5) and a concentric cold-air stream (6) at a blower opening (7). As the device (1), an air nozzle attachment (8) embodied as connectable to the blower opening (7) is provided of a kind such that the air nozzle attachment (8), from the central hot-air stream (5) and the concentric cold-air stream (6) of the hair dryer (2), generates a hot-air stream (9) and a cold-air stream (10) that are located side by side (FIG. 1).

Abstract: The method for simultaneously dyeing and permanent shaping of hair includes dividing the hair into strands an winding the strands onto curlers: mixing a hair shaping component (A) containing from 6 to 15 percent by weight of a keratin-reducing substance with a dye component (B) to form a dyeing and shaping composition prior to application on the hair; treating the hair with the dyeing and shaping composition and then allowing it to act on the hair for an acting time sufficient for the permanent shaping; after that, treating the hair with a fixing composition; allowing the fixing composition to act on the hair from 1 to 40 minutes and then subsequently rinsing the hair. The dye component (B) contains at least one oxidative coupler compound and at least one oxidative dyestuff selected from a group consisting of certain 4,5-diamino-pyrazole derivatives and certain aminophenol derivatives.

Abstract: The present invention has for an object compounds of formula (I) and colorants containing these 4-aminobiphenyl-3-ol derivatives of general formula (I) for dyeing keratin fibers, particularly hair, wherein R1 and R2 independently of each other denote hydrogen, a halogen atom, a cyano group, a hydroxyl group, a C1-C4-alkoxy group, a C2-C4-hydroxyalkoxy group, a C1-C6-alkyl group, a nitro group, a trifluoromethyl group, a —C(O)H group, a —C(O)CH3 group, a —C(O)CF3 group, an —Si(CH3)3 group or a C1-C6-hydroxyalkyl group or R1 and R2 together form an —O—CH2—O— bridge.

Abstract: The new 7-nitro-2,1,3-benzoxadiazole compounds and 7-nitro-2,1,3-benzthiadiazole compounds of formula (I) are: Dyeing agents for keratin fibers, containing the compounds of formula (I), and methods of dyeing hair with these dyeing agents are described.

Abstract: The new N-heteroarylmethyl-p-phenylenediamine derivatives have the general formula (I), Oxidation hair dyeing agents are described based on a combination of developing and coupling substance, which contain at least one N-heteroarylmethyl-phenylenediamine derivative of the formula (I), or a physiologically tolerated salt thereof.
