Composition comprising a peroxygenated salt, a hydrocarbon with a melting point greater than or equal to 85°c, and at least 10% fatty substance

A method for lightening keratin fibers, comprising:

• (1) mixing a composition A with a composition B comprising hydrogen peroxide, wherein composition A comprises:
• (i) one or more peroxygenated salts;
• (ii) one or more hydrocarbons with a melting point of greater than or equal to 85° C., and
• (iii) one or more fatty substances other than the hydrocarbons with a melting point of greater than or equal to 85° C., wherein the total amount of fatty substance(s) (iii) is greater than or equal to 10% by weight, relative to the total weight of the composition;
• and
• (2) applying the mixture to the keratin fibers.

A device for lightening keratin fibers comprising at least two compartments,

• wherein the first compartment comprising a composition A comprising:
• (i) one or more peroxygenated salts;
• (ii) one or more hydrocarbons with a melting point of greater than or equal to 85° C., and
• (iii) one or more fatty substances other than the hydrocarbons with a melting point of greater than or equal to 85° C., wherein the total amount of fatty substance(s) (iii) is greater than or equal to 10% by weight, relative to the total weight of the composition;
• wherein the second compartment comprising a composition B comprising hydrogen peroxide.
