Abstract: The invention refers to the manufacturing of a novel group of sulfur dyes in which are used, as raw material, different kind of natural “biomass”, usually existing in the nature, and transforming them into soluble dyestuffs, capable to dye textile fibers, preferably cellulose fibers and derivatives, as cotton, viscose, paper, tencel, with high strength and fast color properties. For this purpose, the concept “Biomass”, is defined as the residual product obtained from the usual human crop activities, in agricultural and forestry sectors.

Abstract: The present invention relates to the cosmetic use, as an antidandruff agent, of catalytic oxidation compounds chosen from porphyrins, or of a cosmetic composition comprising the same.

Abstract: Hair conditioning formulations containing a particular combination of cationic surfactants, have improved hair care benefits while maintaining excellent in-use characteristics. The compositions contain a first cationic surfactant such as cetyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride and behenyl trimethyl ammonium chloride. A second hydrophilically substituted cationic surfactant such as cocamidopropyl-N-2-hydroxyethylcarbamoylmethyldimethylammonium chloride, and a lipid material such as cetyl alcohol. Although formulations of the invention are based principally on cationic surfactant, and generally contain no anionic or amphoteric surfactant, they provide an acceptable level of cleaning and lathering whilst still conveying the wet slippy feel desired by consumers in connection with conventional hair conditioners.
