1. A solid anhydrous cosmetic composition in particle form, comprising:
at least one anionic surfactant chosen from:
(C6-C24) alkyl sulfates;
(C6-C24) alkyl ether sulfates;
(C6-C24) alkylsulfosuccinates;
(C6-C24) alkyl ether sulfosuccinates;
(C6-C24) acylisethionates;
(C6-C24) acylsarcosinates;
(C6-C24) alkyl ether carboxylates;
polyoxyalkylenated (C6-C24)alkyl(amido) ether carboxylic acids or salts thereof;
(C6-C24) acylglutamates;
(C6-C24) acylglycinates; or
mixtures thereof,
wherein said at least one anionic surfactant is present in an amount of at least about 30% by weight, relative to the total weight of the composition;
at least one amphoteric surfactant present in an amount ranging from about 5% to about 50% by weight, relative to the total weight of the composition,
wherein said composition comprises at least one amphoteric surfactant chosen from (C8-C20)alkylbetaines, (C8-C20)alkylamido(C1-C6)alkylbetaines, (C8-C20)alkylamphoacetates, (C8-C20)alkylamphodiacetates, or mixtures thereof; and
at least one filler present in an amount of at least about 10% by weight, relative to the total weight of the composition, wherein the at least one filler comprises at least one mineral filler chosen from solid salts of alkali metals, solid salts of alkaline-earth metals and silicates.
