Abstract: A method of preparing a cosmetic composition includes selecting at least one enclosure from a plurality of enclosures containing different substances, and causing a fluid to flow through the enclosure(s). The enclosures may be disposed on a common extractor apparatus and/or form part of a common refill. The fluid passing through the enclosure is collected and constitutes all or part of a cosmetic composition.

Abstract: A method of preparing a cosmetic composition includes inserting a refill having an enclosure containing a plurality of substances into an extractor apparatus and subjecting the plurality of substances to fluid injection conditions and/or to external action. The extractor apparatus is able to inject at least one fluid into the enclosure. The method allows at least one of the substances to be extracted in differentiated manner.

Abstract: A method of preparing a cosmetic composition includes causing at least one fluid to flow through an enclosure containing at least one substance to be extracted, and collecting the extraction solution in a receptacle. The method further includes delivering more of the same fluid to the receptacle that does not flow through the enclosure so as to obtain a predefined volume of composition in the receptacle.

Abstract: A method of preparing a cosmetic composition includes injecting into a plurality of enclosures containing different substances at least one fluid via a plurality of injectors. The method produces a plurality of solutions which, after mixing, form all or part of the cosmetic composition.
