A method of preparing a cosmetic composition, and an assembly and a refill for implementing such a method

摘要

The preparation of cosmetic composition for conditioning colored products (P1, P2), comprises selecting an enclosure among several enclosures containing different products, and circulating water through enclosures to collect a solution of the composition. The enclosures are arranged on an extractor and forming a part of a refill. The water simultaneously/non-simultaneously circulates in several enclosures. The water is injected under vapor and liquid phase in enclosures using injectors in which a temperature of the water is higher than 80[deg]C and a pressure is 10 bars. The preparation of cosmetic composition for conditioning colored products (P1, P2), comprises selecting an enclosure among several enclosures containing different products, and circulating water through enclosures to collect a solution of the composition. The enclosures are arranged on an extractor and forming a part of a refill. The water simultaneously/non-simultaneously circulates in several enclosures. The water is injected under vapor and liquid phase in enclosures using injectors in which a temperature of the water is higher than 80[deg]C and a pressure is 10 bars. Before selecting the enclosure, a color of person is analyzed to test with the cosmetic composition. The selection is carried out on the basis of the color. The enclosures comprise a keratin-coloring agent. The solution resulting from the extraction is collected in a container. The container comprises a compound to be mixed with the solution. The enclosures are partially defined by a first wall through which the injector is passed and a second wall to disperse the water in the enclosure under a pressure. Independent claims are included for: (1) an unit for preparing cosmetic composition; (2) an extraction apparatus; and (3) a refill.
