  The present invention relates to an oxidative hair colouring and bleaching composition comprising an oxidizing agent, a source of carbonate ions, an alkalising agent, and specific dyes, as defined herein below, utilised at pH 9.5 and below which improved colour delivery and intensity whereby different colours/ shades and chromophores are provided, are compatible with current dyes and dye precursor systems and result in improved lift and lightening for blonde shades, excellent dye deposition and colour and improved grey coverage. Moreover, the compositions of the present invention also exhibit low odour and deliver a high level of lift and lightening equal to the currently utilised ammonia/peroxide systems, whilst reducing the concentration of peroxide and reducing the hair fibre damage.

  本发明涉及一种氧化性染发和漂白组合物，该组合物由氧化剂、碳酸根离子源、碱化剂和下文定义的特定染料组成，在 pH 值为 9.5 及以下时使用，可提供不同的颜色/色调和发色团，从而改善颜色的传递和强度，与当前的染料和染料前驱体系统兼容，并可改善金发色调的提升和提亮效果、优异的染料沉积和颜色以及改善灰色覆盖。此外，本发明的组合物还具有低气味的特点，并能提供与目前使用的氨/过氧化物系统相当的高水平的提亮和增白效果，同时还能降低过氧化物的浓度，减少对头发纤维的损伤。
• Dye-containing pellets and their use

  公开号：EP1820487A1

  公开（公告）日：2007-08-22

  The present patent application relates to dye-containing pellets obtained by (a) homogeneous mixing of a starting material containing at least one natural and/or synthetic dye with a suitable carrier material and then coating with a suitable encapsulation material or (b) coating a suitable carrier material with a mixture of at least one natural and/or synthetic dye and at least one suitable, encapsulation material, to the use of said pellets for preparing colorants for keratin fibers and to the colorants based on said pellets. Furthermore the present patent application relates to the use of these pellets for increasing the shine of the keratin fibers, reducing the scalp colouring of hair dyes, improving the protection for the cortex, increasing the colourant efficiency and reducing the load of colourants, and improving the wash resistance.

  本专利申请涉及通过以下方法获得的含染料颗粒：(a) 将含有至少一种天然和/或合成染料的起始材料与适当的载体材料均匀混合，然后涂上适当的封装材料，或 (b) 在适当的载体材料上涂上至少一种天然和/或合成染料与至少一种适当的封装材料的混合物；使用所述颗粒制备角蛋白纤维着色剂；以及基于所述颗粒的着色剂。此外，本专利申请还涉及使用这些颗粒增加角蛋白纤维的光泽，减少染发剂对头皮的染色，改善对皮质的保护，提高染色剂的效率，减少染色剂的负荷，以及改善耐洗性。
• Colouring composition for keratin fibres

  公开号：EP2226065A2

  公开（公告）日：2010-09-08

  Present invention relates to a colouring composition for keratin fibres especially for human hair with exceptionally improved colour and shade stability. Accordingly, the first object of the present invention is a colouring composition for keratin fibres especially human hair comprising, in a cosmetically acceptable medium, at least one oxidative dyestuff precursor, 1,3-bis(2,4-diaminophenoxy) propane and/or its respective salts as a coupling agent and at least one direct dye. In an especially preferred from of the present invention the colouring compositions are substantially free from mono cyclic m-phenylenediamine coupling agent. With the term "mono cyclic m-phenylenediamine", it is meant that the compound comprises only one cyclic group, preferably a benzene ring, in its molecule.

  本发明涉及一种用于角蛋白纤维，特别是用于人类头发的染色组合物，其颜色和色调的稳定性得到了极大的改善。因此，本发明的第一个目的是一种用于角蛋白纤维（尤其是人类头发）的染色组合物，该组合物在美容上可接受的介质中包含至少一种氧化染料前体、作为偶联剂的 1,3-双（2,4-二氨基苯氧基）丙烷和/或其各自的盐以及至少一种直接染料。在本发明的一个特别优选方案中，染色组合物基本上不含单环间苯二胺偶联剂。所谓 "单环间苯二胺"，是指化合物分子中只有一个环基，最好是一个苯环。
