The present invention relates to a composition (A) for dyeing or lightening keratin fibres, in the form of a microemulsion comprising: i) at least water, ii) at least one oil, the total oil content being greater than or equal to 5% by weight relative to the weight of the composition; iii) at least one surfactant, the total surfactant content being less than or equal to 19% by weight relative to the total weight of the composition; and iv) at least one compound chosen from: a. colouring agents chosen from direct dyes and oxidation dyes, and/or mixtures thereof; and b. oxidizing agents, c. basifying agents, and mixtures thereof, v) optionally at least one liquid organic compound with a Hansen solubility parameter value δH of greater than 0 and less than 16 MPa½. The present invention also relates to a process for dyeing or lightening keratin fibres, comprising the application of a composition A, optionally preceded by mixing with a composition B comprising at least one oxidizing agent, and also to a multi-compartment device and to a ready-to-use composition resulting from the mixing of compositions (A) and (B). The composition according to the invention makes it possible to lighten or to dye keratin fibres strongly, efficiently and homogeneously while at the same time being stable and easy to apply. |
