  • Patent number: 7198650
    Abstract: The present disclosure relates to a method of dyeing human keratin materials with a lightening effect with a composition comprising, in a cosmetically acceptable medium, at least one fluorescent dye that is soluble in the cosmetically acceptable medium and at least one surfactant chosen from amphoteric surfactants and nonionic surfactants. The present disclosure also relates to compositions comprising at least one particular fluorescent dye that is soluble in the cosmetically acceptable medium and at least one surfactant chosen from amphoteric surfactants and nonionic surfactants, and also to processes using these compositions, and devices for these compositions.

  • Patent number: 7151079
    Abstract: The invention relates to novel cosmetic compositions comprising, in a cosmetically acceptable medium, at least one fructan, at least one polysaccharide and at least one beneficial agent, a combination which gives the cosmetic compositions a velvety-smooth texture. Said composition can be easily rinsed off. Hair treated with said composition feels soft and contains no residue. The compositions are particularly suitable for washing and/or conditioning keratinous matter, such as the hair and skin.

  • Publication number: 20040105833
    Abstract: The invention concerns novel cosmetic compositions comprising in a cosmetically acceptable medium at least a starch phosphate and at least a particular non-siliconized cationic polymer. Said association provides a fluid texture to the cosmetic compositions, and said compositions are easily rinsed away. Hair treated with said composition have a soft residue-tree feel. Said compositions are used in particular for washing and/or conditioning keratinous materials such as hair or the skin.
