Process for cosmetic treatment of keratin materials

Disclosed is an anhydrous composition comprising particles having a core containing a beneficial agent and an envelope surrounding the core. The envelope comprises a hydrophobically modified polysaccharide and a water-soluble carbohydrate and/or water-soluble polyol. The particles have a poured powder density from 300.0 g/l to 600.0 g/l and an absolute density of greater than 1.0. The composition also comprises a fatty phase comprising a solid fatty substance and an oil. The composition has a hardness measured at 32&#xb0; C. at a humidity of 40% from 15 kPa to 150 kPa. Also disclosed are uses of the composition for caring for and/or for the hygiene of and/or for conditioning and/or for fragrancing and/or for making up a keratin material. The composition can be used for treating body odor wherein the composition comprises a deodorant active agent and/or antiperspirant active agent in free form and/or in encapsulated form.

Method for straightening human hair fibers using heating means and an &#x3b1;-hydroxy acid derivative

The invention relates to a process for straightening keratin fibers, comprising: (i) a step in which a straightening composition containing at least two denaturing agents is applied to the keratin fibers, (ii) a step in which the temperature of the keratin fibers is raised, using a heating means, to a temperature of between 110 and 250&#xb0; C.

Process for straightening keratin fibres with a heating means and denaturing agents

The present disclosure relates to specific dimercaptoamides, reducing compositions for permanently reshaping keratin fibers comprising the dimercaptoamides, for instance, human keratin fibers such as the hair; and processes for reshaping keratin fibers comprising the application of said reducing compositions. The present disclosure also relates to processes for preparing the dimercaptoamides.

Dimercaptoamides, compositions comprising them as reducing agents, and processes for permanently reshaping keratin fibers therewith

The invention concerns a method for treating hair keratin fibers to provide them with new appropriate properties, comprising the following steps: reducing the sulphur bonds of hair keratin to generate only at the surface of the fibers at a depth less than 10 &#x3bc;m. reactive sites and in fixing covalently on said reactive sites at least one active compound for providing the hair keratin fibers with new appropriate properties, said active compound containing at least a reactive function capable of reacting with said reactive sites formed at the keratin fiber surface. This method is applicable to the treatment of fibrous or non-fibrous keratin substances of human or animal origin.
