Abstract: The invention relates to a cosmetic composition comprising at least one cationic derivate of fructan and at least one anionic surfactant, non-ionic surfactant or amphoteric surfactant. The cationic derivate of fructan has preferably a molecular weight of less than 30000 g/l and preferably a solubility in water at a temperature of 25° C. of at least 20 wt %. The invention further relates to a method for treating hair with such a cosmetic composition.

Abstract: A method of manufacturing nanowires (104) is provided, according to which method the nanowires are prepared by anodic etching a semiconductor substrate (10) with an alternating current density, so as to create first regions (4) and second regions (5) with different diameters. Thereafter, the diameters are reduced by preferably repeated oxidation and etching. Finally, the nanowires (104) are dispersed in a dispersion by ultrasonic vibration, through which the coupled nanowires split into individual nanowires of substantially uniform length. The nanowires may then be provided with a surface layer of a suitable material, for instance a luminescent material.
