DYE COMPOSITION USING A SPECIFIC NON-IONIC HYDROTROPIC COMPOUND IN A MEDIUM RICH IN FATTY SUBSTANCES, METHODS AND DEVICE

摘要

The present invention relates to a composition for dyeing keratin fibres, comprising at least one fatty substance; at least one surfactant; at least one dye for keratin fibres, having a logP greater than or equal to 1.3; at least one alkaline agent; at leastone chemical oxidizing agent; at least 0.5% by weight relative to the weight of the composition of at leastone liquid non-ionic compound having a Hansen parameter delta H below 16 MPa ½;the fatty substance content representing in total at least 25% by weight relative to the total weight of the composition. The present invention also relates to a method using this composition, and to multi-compartment devices that are suitable for using this invention.
