| 摘要 |
The aim of the invention relates to a product for the oxidative dyeing of keratin fibres, comprising at least two pre-fabricated preparations (A) and (B) which are separated from each other, the first preparation (A) contains, in a cosmetic carrier, (A1) hydrogen peroxide, and (A2) at least one chelating agent from the group consisting of 1-hydroxyethane-1,1-diphosphonic acid (HEDP), ethylenediamine tetramethylene phosphonic acid (EDTMP), diethylenetriamine pentamethylene phosphonic acid (DTPMP), aminotrimethylene phosphonic acid (ATMP), N,N-bis[2-[bis(carboxymethyl)amino]ethyl]glycine, ethylene diamine-N,N'-disuccunic acid (EDDS), 2-hydroxy propylene diamine-N,N'-disuccunic acid (HPDDS), ethylenediamine-N,N'-diglutaric acid (EDDG), ethylenediamine-N,N'-bis-(orthohydroxyphenyl)acetic acid (EDDHA) and/or a physiologically compatible salt thereof, the second preparation (B) contains, in a cosmetic carrier, (B1) at least one alkalising agent, the preparation (A) being pre-fabricated in a first container (container A), which comprises at least two layers, wherein, an inner layer of the container (A) has a layer made from a synthetic polymer (I), and an outer layer of the container (A) has a metallic layer, and the preparation (B) is prefabricated in a second container (container B) which comprises at least two layers, wherein an inner layer of container (B) has a layer made from a synthetic polymer (I) and an outer layer of the container (B) has a metallic layer. |
