INVERT EMULSION COMPRISING AN AQUEOUS SOLUTION OF HYDROGEN PEROXIDE AND AN INERT PHASE WITH WATER SOLUBILITY OF LESS THAN 1 %

摘要

The invention relates to an invert emulsion for bleaching keratin fibres and, in particular, human keratin fibres, such as hair.According to the invention, the emulsion consists of an inert phase comprising at least one non-oxygenated, non-perfluorinated liquid compound having a water solubility at 25 °C of less than 1 % and an aqueous solution of hydrogen peroxide, said inert phase representing at least 20 wt.- % of the total weight of the invert emulsion and the volume-average diameter of the dispersed aqueous phase being greater than 200 nm. The invention also relates to a bleaching method which employs the inventive invert emulsion either as it is or in the form of a ready-to-use composition and to the use of said emulsion for bleaching keratin fibres. The inventive emulsion can be used to lighten keratin fibres quickly and significantly while limiting damage to said fibres and skin irritation.
