    • Agents for coloring keratin-containing fibers, in particular human hair, that contain encased oxidation dye precursor products. More-uniform coloring, which is independent of which strands are wetted first or last with the coloring product, is thereby ensured. The casing of the oxidation dye precursor products is made up of an encapsulating material made of methacrylic-acid, methacrylic acid-ester, or vinyl-acetate homo- or copolymers, or shellac, as well as at least one release agent. Contact time is equalized over time and shortened overall, resulting in a reduction in hair damage due to excessively long contact times. A method for manufacturing coloring agents for keratinic fibers, containing coated particles is also provided.
    • 用于着色含有包含氧化染料前体产物的含角蛋白的纤维,特别是人类头发的剂。 从而确保了更均匀的着色,其独立于首先或最后被着色产物润湿的丝束。 氧化染料前体产物的外壳由由甲基丙烯酸,甲基丙烯酸酯或乙酸乙烯酯均聚物或共聚物或虫胶制成的包封材料以及至少一种脱模剂制成。 随着时间的推移,接触时间相等并缩短整体,导致由于接触时间过长导致的头发损伤减少。 还提供了一种制造含有包被颗粒的角质纤维着色剂的方法。
