    Abstract: Process for dyeing keratinous fibres, comprising the step of applying to these fibres at least one composition A containing, in a medium appropriate for dyeing, at least one mono- or di-hydroxyindole the application of the composition A being preceded or followed by the application of a composition B containing, in a medium appropriate for dyeing, at least one quinone derivative chosen from ortho- or para-benzoquinones, monoimines or diimines of ortho- or para-benzoquinones, 1,2- or 1,4-naphthoquinones, sulphonimides of ortho- or para-benzoquinones, alpha , omega -alkylene-bis-1,4-benzoquinones, or 1,2- or 1,4-naphthoquinone-monoimines or -diimines; the mono- or di-hydroxyindoles and the quinone derivatives being chosen such that the oxidation-reduction potential difference DELTA E between the oxidation-reduction potential Ei of the mono- or di-hydroxyindoles, determined at pH 7 in a phosphate medium on a vitreous carbon electrode by voltametry, and the oxidation-reduction potential Eq of the quinone derivative determined at pH 7 in a phosphate medium by polarography on a mercury electrode and relative to a saturated calomel electrode is such that DELTA E=Ei-Eq

    Abstract: A process is described which consists, in a first stage, in applying a composition based on a substance of vegetable or animal origin, a synthetic organic substance or a mineral substance, in suspension or in solution in a solvent and having a viscosity suitable for application to the hair, or as a powder, and making it possible to prevent or substantially to limit the passage of the dyestuffs and/or of the dyestuff precursors as far as the scalp, and, in a second stage, in dyeing the hair using one or more compositions, at least one of which contains either an oxidizable dyestuff or a direct dyestuff, the dyeing being followed, after an interval sufficient for coloring the hair, by rinsing and optionally by shampooing.

    Abstract: A container for storing and dispensing a liquid product includes a pump operated by a reciprocable control member and associated with a pneumatic servo system. The actuation is achieved by supply of gas pressure, for example, from a reservoir of gas at a pressure of the order of 5 bars, and this is used to actuate the control member of the pump, for example a stepped piston incorporating a pressure multiplying effect. Much higher operating forces on the reciprocable control member can be achieved with this system than were possible by purely manual operation of the valve control member.

    Abstract: The bottle (1) comprises an enclosure (2), in the form of a bent tube, and a manual spray pump (3). The enclosure (2) is a bent tube of small cross-section and folded back upon itself several times. A plurality of elbow bends (8) connect, by their ends, straight tube sections (7) in order to form the folded-back tube. The bundle of straight tube sections (7) is formed in a cylinder (6) made of resin, glass or metal, for example. The section formed in the axis of the cylinder (6) connects with the pump (3). The opposite end of the bent tube emerges to the outside through an opening (7a). The spray bottle can be used in all positions. The liquid to be dispensed is retained by capillary effect and the pump (3) is always supplied. The bottle is used for the packaging and dispensing of cosmetic products such as a lotion, lacquer or perfume.
