摘要 |
The invention relates to the use of a thickened combination of at least one cross-linked or non cross-linked polyacrylate and at least one cross-linked copolymer of methacrylic acid and C1-C4-alkylacrylate for increasing the viscosity in alkaline, oxidative hair treatment agents. The invention also relates to a cosmetic agent for changing the colour of keratin fibres, which is produced directly prior to use by mixing a preparation (M1 ), containing at least one colour-changing component, and an oxidation agent preparation (M2), containing an aqueous, cosmetic carrier as a chemical oxidation agent, at least one hydrogen peroxide which has a viscosity of between 5 - 100 Pas. Said oxidation agent preparation also comprises at least one thickened combination of at least one cross-linked or non cross-linked polyacrylate and at least one cross-linked copolymer of methacrylic acid and C1-C4 alkyl acrylate. |
