摘要:
A process for treating keratinous material, in particular the hair, for the purpose of obtaining a permanent reshaping of the latter, in particular in the form of permanent-waved hair. The process includes the following steps: (i) a so-called "acidic composition" containing at least one carboxylic acid and/or one of the associated salts thereof is applied to the keratinous material to be treated, the pH of the acidic composition ranging from 2.5 to 7, (ii) the keratinous material thus treated is rinsed, (iii) a reducing composition containing at least one thiol is applied to the keratinous material thus rinsed, the keratinous material is placed under mechanical tension before, during or after the application of the reducing composition or before the application of the acidic composition, (iv) the keratinous material thus treated is then rinsed, (v) an oxidizing composition is applied to the keratinous material thus rinsed, (vi) and, finally, the keratinous material thus treated is rinsed again, the keratinous material being separated directly before or after the rinsing operation in step (vi) from the tension referred to above directly before or after the rinsing operation in step (vi).
摘要:
A cosmetic composition for treatment of human keratinous organs is na aqueous medium having a pH ranging from 5 to 12.5 and contains (a) as an active agent a reducing agent, a dyeing agent or an oxidizing agent and (b) a diaminoalkane which combats or reduces residual unpleasant odor of human keratinous organs treated with the active agent.
摘要:
The invention relates to a catalytic process for the synthesis of an alcohol by reaction of an epoxide with a nucleophilic compound containing a labile hydrogen, such as an alcohol, a phenol, a primary amine or a carboxylic acid.The catalyst is a metal complex of general formula (I)[M[Co(CO).sub.4 ].sub.2 ].sub.x in which x is equal to 1 or 2 and M denotes tin, lead and cadmium.The reaction preferably takes place in the presence of carbon monoxide.This process makes it possible to increase the yield and the selectivity of the reaction and the stereoselectivity for alcohol in the case of which the hydroxyl formed is attached to the least hindered carbon atom of the epoxide.The invention also relates to the new complexes of formula (I) in which x equals 2.It also relates to a process for the electrosynthesis of these new compounds by electroreduction of Co.sub.2 (CO).sub.8 in an organic solvent medium in a cell in which the anode consists of the metal M, followed by isolation of the complex, the temperature of the reaction mixture and that at which the complex is isolated being lower than 25.degree. C.
摘要:
A method of cosmetically modifying the appearance of the outline of the eye, the method including the step consisting in applying at least one patch on the movable upper eyelid, the application face of the patch having a predefined non-plane shape with multi-directional curvature, or at least one patch made of a material suitable for responding to stress by deforming in non-elastic manner as to take up multi-directional curvature on the eyelid and conserve the curvature when the stress ceases.
摘要:
A cosmetic or dermatological system includes a packaging and dispenser device containing one or more compositions from which the dispensed preparation is prepared, a surroundings sensor that is suitable for delivering at least information associated with a physical magnitude of the surrounding environment of the device, an adjustment system that is coupled to or suitable for coupling to the packaging and dispenser device, and that enables at least one characteristic of the dispensed preparation to be varied, and a processor for automatically controlling the adjustment system as a function of data delivered by the surroundings sensor or for informing the user, as a function of the data, about an action to be exerted on the adjustment system.
摘要:
The present invention relates to an element (20) for the application of fibers (F) on human keratinous fibers, comprising fibers (F) held together in a predefined way by a liquefiable adhesive in the solid form, the liquefying of the adhesive on application making it possible for at least a portion of the fibers to separate from the element.
摘要:
A cosmetic or dermatological system includes a packaging and dispensing device including one or more compositions on the basis of which a product is delivered, an adjustment system coupled or able to be coupled to the packaging and dispensing device, making it possible to modify the amount dispensed and/or at least one property of the product dispensed by the packaging and dispensing device, an electronic means for executing a program and acting automatically on the adjustment system, or for indicating to the user an action to be exerted on the adjustment system, to make the adjustment evolve in the course of the use of the device, the program determining the evolution of the adjustment as a function at least of a quantity representative of the number of uses of said device or of the amount of said product or of at least one of said compositions and already dispensed.
摘要:
The invention relates to a dyeing composition comprising a fluorescent disulfide dye and to a method of dyeing keratin materials, with a lightening effect, that employs said composition. It likewise relates to new fluorescent disulfide dyes and to their uses in the lightening of keratin materials. The composition allows a particularly persistent lightening effect to be obtained.
摘要:
The present invention relates to compositions comprising peptides with antidandruff activity. The invention also relates to the use of these peptides as antidandruff agents, or in methodes for treating dandruff.
