Abstract: The present invention relates to a process for preparing a composition for washing keratin materials, in particular human keratin fibres such as the hair, comprising the mixing of an anhydrous solid composition comprising one or more anionic surfactants and one or more amphoteric or zwitterionic surfactants with water, followed by agitation and then leaving to stand the aqueous composition obtained from this mixing.

Abstract: The present invention relates to an anhydrous solid composition comprising one or more anionic surfactants, one or more amphoteric or zwitterionic surfactants and one or more C8-C32 fatty acid salts. The invention also relates to a method for the preparation of an aqueous composition for washing, and optionally in addition conditioning, keratin fibres starting from the anhydrous solid composition according to the invention, to the use of an anhydrous solid composition according to the invention for washing, and optionally in addition conditioning, keratin fibres, and also to a kit for the preparation of the aqueous composition for washing, and optionally in addition conditioning, keratin fibres.

Abstract: Flexible solid cosmetic composition comprising sulfonate anionic surfactants, fatty esters and fatty alcohols, and cosmetic treatment method The present invention relates to an aqueous cosmetic composition in flexible solid form, comprising (i) at least 10% by weight of anionic surfactants comprising a sulfonate group, (ii) esters of fatty acid(s) comprising at least 12 carbon atoms, and (iii) fatty alcohols comprising at least 16 carbon atoms. The composition finds a particular application as a composition for cleaning or washing keratin materials, in particular the hair. The invention also relates to a cosmetic treatment method, in particular for caring for, cleaning and/or conditioning keratin materials using said composition.

Abstract: The present invention relates to an aqueous cosmetic composition which is in the form of a flexible solid, comprising: from 25% to 70% by weight of one or more anionic surfactants and one or more types of non-hollow solid particles, said composition comprising at least one anionic surfactant chosen from acylisethionates, preferably having an acyl group containing from 6 to 30 carbon atoms. Said composition is of preferential use as a composition for cleaning or washing keratin materials, in particular the hair. The invention also relates to a cosmetic treatment process, in particular for caring for, cleaning and/or conditioning keratin materials, using said composition.

Abstract: The present invention relates to an aqueous cosmetic composition in flexible solid form, comprising: at least 12 wt.-% of one or more anionic surfactants, and one or more polymer conditioning agents, said composition comprising at least one anionic surfactant selected from among acyl isethionates. The composition is preferably suitable for use as a composition for cleaning or washing keratin materials, particularly hair. The invention also relates to a cosmetic treatment method intended in particular for the care, cleaning and/or conditioning of keratin materials using said composition.
