Claims29
A method of preparing a cosmetic composition, the method comprising:
- a) causing at least one fluid to flow through at least one enclosure containing at least one substance to be extracted, and collecting at least one extraction solution in a receptacle;
- and
- b) delivering more of the same fluid to the receptacle without causing it to flow through the enclosure so as to obtain a predefined volume of composition in the receptacle.
An apparatus for preparing a cosmetic composition by causing at least one fluid to flow through at least one enclosure containing at least one substance to be extracted, the apparatus comprising:
- a support system for supporting the enclosure;
- and
- an injector system for:
- firstly injecting the fluid through the enclosure so as to produce at least one solution that is collected in a receptacle;
- and
- secondly delivering more of the same fluid to the receptacle without the fluid flowing through the enclosure.
