Estimating the term…
Colorants, in particular hair colorants, frequently contain ammonia, which leads to an unpleasant odor during use and can irritate skin, hair and the lungs. In the case of known alternatives to ammonia, the coloring performance or the durability of the color is frequently weaker. This problem is solved by proposing a colorant which comprises an alkalizing agent to open the cuticle layer of hair and/or to swell hair and/or skin, wherein the alkalizing agent comprises or consists of particles of bioactive glass as alkalizing agent.
A colorant that comprises an alkalizing agent for effecting opening of the cuticle layer of hairs and/or swelling of hairs and/or skin, the alkalizing agent comprising particles of bioactive glass, wherein the colorant has a DH in the 6 to <8 range and comprises particles of bioactive glass as a local alkalizing agent.
