    摘要: The invention relates to agents having a pH value of between 2 and 6.5, said agents containing a combination of: (a) at least one organic compound, which carries at least one thiol group and at least one optionally derivatised carboxyl group, for example L-cysteine; (b) at least one inorganic compound selected from the group that is formed from cyclic, organic carbonates, glycerin and derivatives thereof and C
    4 -C
    12 fatty acid dimethylamides; (c) at least one (C
    10 to C
    30 ) fatty alcohol; and (d) at least one emulsifier selected from at least one compound of the group consisting of (i) (C
    10 to C
    30 ) fatty alcohols that are alkoxylated with between 2 and 100 units (C
    2 - and/or C
    3 -) alcohol ether, (ii) amphoteric emulsifiers substituted with at least one (C
    10 to C
    30 ) hydrocarbon group. These low-odour agents can be used in the rapid and effective decolorization of dyed fibres containing keratin, in particular human hair.

    摘要: The invention relates to compositions comprising a combination of (a) at least one organic compound which carries at least one thiol group and at least one optionally derivatized carboxyl group, for example L-cysteine, and (b) at least one organic compound selected from the group which is formed from cyclic, organic carbonates, glycerol and its derivatives and C

    12 fatty acid dimethylamides. Using these low-odour compositions it is possible to reductively decolour coloured keratin-containing fibres, in particular human hair, in a rapid and effective manner.
