Abstract: The present invention relates to a process for purifying metal nanowires, comprising at least the following steps: (i) providing a suspension of metal nano-objects in a hydroalcoholic solvent medium having a viscosity at 25° C. strictly less than 10 mPa·s, the metal nano-objects including fine nanowires and additional nanoparticles different from the fine nanowires; (ii) adding, to the metal nano-object suspension, metalloid or metal oxide nanoparticles having a diameter less than or equal to 50% of the average diameter of the nanowires; (iii) allowing the suspension of metal nano-objects with the added metalloid or metal oxide nanoparticles to settle under conditions conducive to the precipitation of the fine metal nanowires; and (iv) recovering the settled solids made from the fine metal nanowires.

Abstract: An abrasive sawing or polishing substrate includes a substrate, a binder C1 covering at least a portion of the substrate, and abrasive particles having an at least partial coating, C2. The abrasive sawing or polishing substrate also includes a coating C3 coating binder C1 and the abrasive particles coated with C2 and at least one light-emitting compound. The abrasive particles coated with C2 are in contact with binder C1 and with coating C3.

Abstract: The present invention relates to a dyeing composition for the oxidative dyeing of human keratin fibres, at a pH less than 8, comprising one or more oxidative dye precursors, one or more fatty alcohols and fatty esters as well as one or more cationic surfactants, the weight ratio of fatty alcohol(s) to fatty acid ester(s) being greater than 2 and less than 10. It also relates to a ready-to-use composition obtained by extemporaneous mixing with an oxidizing composition prior to using the aforementioned dyeing composition. It also relates to a method of colouring keratin fibres in which the ready-to-use composition is applied on said fibres. According to another variant of the method of colouring, the aforementioned dyeing composition and the oxidizing composition are applied successively and without intermediate rinsing. The invention also relates to a device with several compartments that are suitable for its application.

Abstract: The present invention relates to a process for dyeing keratin fibres, which comprises the application to the fibres of a composition containing at least one cationic polymer, rinsing of the keratin fibres, the application of a composition containing at least one anionic colored polymer, and rinsing of the keratin fibres. Such a process makes it possible to obtain an improvement in the coloration of the keratin fibres.

Abstract: The present invention relates to a process for dyeing dark keratin fibres, which comprises the application to the fibres of a composition containing at least one anionic chromophore-containing coloured polyelectrolyte, wherein the application is not followed by a rinsing step. Such a process makes it possible to obtain a coloration which is easy to carry out and which preserves the cosmetic appearance of the keratin fibres.
