    • The two-component hair treatment product consists of one component (A) and another component (B). Component (A) contains an acid and component (B) contains a base. Less than 3 g of the base and/or acid are soluble in 100 ml of water at 20° C. The acid is preferably a dicarboxylic acid, such as sebacic, dodecanoic dicarboxylic acid or tetradecanoic dicarboxylic acid. The base is preferably ammonia, an alkyl amine or an alkylol amine. Prior to use in a method of permanent hair shaping or hair care, the components are mixed with each other to form a ready-to-apply mixture having an automatically continuously or gradually changing pH that changes within from one to 60 minutes so that damage to the hair due to high pH is avoided. For permanent shaping of hair the initial pH of 8 to 13 falls from about 1 to 4 pH units within from 10 to 30 minutes after mixing the components.
    • 双组分头发处理产品由一种组分(A)和另一种组分(B)组成。 组分(A)含有酸,组分(B)含有碱。 碱和/或酸的少于3克可溶于20℃的100ml水中。酸优选为二羧酸,如癸二酸,十二烷二酸或十四烷酸二羧酸。 碱优选为氨,烷基胺或烷醇胺。 在使用永久性头发成型或头发护理的方法之前,将组分彼此混合以形成即用型混合物,其具有在1至60分钟之间变化的自动连续或逐渐变化的pH,从而损害 避免了高pH下的头发。 对于头发的永久成形,混合组分后,10至30分钟内,初始pH值为8至13的pH值约为1至4个pH单位。

    • The composition for hardening, strengthening and restructuring keratin-containing materials and/or for increasing the volume of keratin-containing fibers, such as hair, contains from 0.3 to 50.0% by weight of one or more reductones, each having a —(HO)C═C(OH)— group. The reductone ingredient is preferably ascorbic or isoascorbic acid, a salt of ascorbic or isoascorbic acid, such as an alkali metal or alkaline earth metal salt, an ester of ascorbic or isoascorbic acid, 6-O-palmitoyl ascorbate, ascorbyl phosphate, 2,3-dihydroxy-2-propenal and hydroxypropanedial. A method of treating keratin-containing materials or fibers to harden, strengthen and restructure keratin-containing materials and/or to increase the volume of the keratin-containing fibers by applying this composition and allowing it to act is described. A method of pre-treating keratin-containing material that is to be subjected to a chemical or physical treatment, such as dyeing or permanent shaping is also described.
    • 用于硬化,强化和重组含角蛋白的材料和/或用于增加含角蛋白的纤维如毛发的体积的组合物含有0.3至50.0重量%的一种或多种还原剂,每种还原剂具有 - (HO) C = C(OH) - 基。 还原酮成分优选为抗坏血酸或异抗坏血酸,抗坏血酸或异抗坏血酸的盐,例如碱金属或碱土金属盐,抗坏血酸或异抗坏血酸的酯,6-O-棕榈酰抗坏血酸,抗坏血酸磷酸2,3 - 二羟基-2-丙醛和羟基丙二醛。 描述了通过应用该组合物并使其起作用来治疗含角蛋白的材料或纤维来硬化,加强和重组含角蛋白的材料和/或增加含角蛋白的纤维的体积的方法。 还描述了预处理待进行化学或物理处理的含角蛋白的材料如染色或永久成形的方法。
