Abstract
The present invention relates to a process for lightening or dyeing keratin materials, in which the following are used: a) a direct emulsion (A) comprising one or more fatty substances in an amount of greater than 25% by weight; one or more oxyalkylenated nonionic surfactants; an amount of water of greater than 5% by weight relative to the total weight of the emulsion, and one or more oxidizing agents, and b) a composition comprising one or more alkaline agents. The invention also relates to a multi-compartment device comprising, in one of them, an emulsion (A), and, in another, a composition (B) comprising one or more alkaline agents.
Claims25
A process for lightening keratin materials, which consists in treating the keratin materials with at least:
- a) a direct emulsion (A) comprising one or more fatty substances in an amount of greater than 25% by weight, one or more oxyethylenated (OE) and/or oxypropylenated (OP) nonionic surfactants, the number of OE and/or OP units being between 1 and 50;
- one or more oxidizing agents, and an amount of water of greater than 5% by weight relative to the total weight of the emulsion, and
- b) a composition (B) comprising one or more alkaline agents.
A multi-compartment device comprising,
- in a first compartment, a direct emulsion (A) comprising one or more fatty substances in an amount of greater than 25% by weight, one or more oxyethylenated (OE) and/or oxypropylenated (OP) nonionic surfactants, the number of OE and/or OP units being between 1 and 50;
- one or more oxidizing agents, and an amount of water of greater than 5% by weight relative to the total weight of the emulsion, and
- in a second compartment, a composition (B) comprising one or more alkaline agents.
An oil-in-water direct emulsion comprising at least 25% of one or more fatty substances, including at least one oil, one or more oxyethylenated (OE) and/or oxypropylenated (OP) nonionic surfactants, the number of OE and/or OP units being between 1 and 50, one or more oxidizing agents and an amount of water of greater than 5% by weight relative to the total weight of the emulsion.
