The present invention relates to a concentrated ingredient for treating and/or modifying surfaces, especially for treating and/or modifying the skin and/or the hair. The invention also relates to the use of this ingredient in cosmetic compositions, for example in shampoos, shower gels or leave-in or rinse-out hair conditioners. The ingredient comprises a conditioning agent and a polymer for aiding deposition.

Concentrated ingredient for treating and/or modifying surfaces, and use thereof in cosmetic compositions

The present invention relates to novel cosmetic compositions, more particularly for treating the skin or the hair, comprising an ampholytic artificial copolymer. The invention also relates to the use of the polymer in cosmetic compositions. The polymer comprises units derived from a polycationic monomer and units derived from a monomer of acidic nature.

Cosmetic composition comprising an ampholytic copolymer

The present invention relates to a process for decomposing organic hydroperoxides in the presence of a catalyst. It provides a process for decomposing organic hydroperoxides in the presence of a catalyst into a mixture of alcohols and ketones, in which the catalyst comprises at least one ruthenium-based catalytically active metallic element incorporated into a solid support chosen from the group comprising metal oxides and carbon blacks, such as the carbon blacks obtained by the pyrolysis of organic compounds. The process of the invention is especially useful in the decomposition of important chemical intermediates such as cyclohexyl hydroperoxide.

Process for catalytically decomposing organic hydroperoxides

A process is provided for the hemihydrogenation of dinitriles to corresponding aminonitriles using hydrogen in the presence of a supported catalyst. The supported catalyst comprises ruthenium supported on a carbon black, called acetylene black, resulting from the pyrolysis of paraffin oils.
