Abstract: The present invention provides a process for reducing oxides of nitrogen to molecular nitrogen in a medium which is superstoichiometric in oxidizing agent using reducing agents in the presence of a catalyst comprising:at least one refractory inorganic oxide at least in part constituted by a zeolite from the group formed by NU-86, NU-87 and EU-1;optionally, at least one element (A) from groups VIB, VIIB, VIII and IB, the transition metals;optionally, at least one element (B) from group VIII, the noble metals comprising platinum, rhodium, ruthenium, iridium and palladium;and optionally at least one element (C) from group IIA, the alkaline-earths and/or group IIIB, the rare earths.

Abstract: A process for coating the surface of pigment and filler particles with an oleaginous and cosmetically functional material, characterized in that an aqueous suspension of the pigment or filler is mixed with an emulsion of said oleaginous material to be coated onto the surface of pigment or filler particles, followed by adding a component capable of breaking the emulsion to the thus obtained mixture, whereby the emulsified material coalesces onto the surface of the pigment or filler particles. The thus obtained pigments or fillers exhibit excellent properties when used in cosmetics.
