System for dispensing a cosmetic product
A system for dispensing a product, having a dispenser that receives at least two cartridges that each have a reservoir containing a base product, a first base product including at least 0.1% by mass of particles exhibiting a difference in density, with the medium which contains them, the particles having a density greater than or equal to 2 g/cm 3 , and a thickener, the dispenser making it possible to deliver at least two base products in adjustable proportions, the viscosity of the first base product being greater than 2 Pa·s is provided.
1. A system for dispensing a product, comprising a dispenser that receives at least two cartridges that each have a reservoir comprising a base product, a first base product in a reservoir of one of the at least two cartridges and a second base product in a reservoir of another of the at least two cartridges,
the first base product comprising at least 0.1% by mass of particles exhibiting a difference in density with a medium which contains them, the particles having a density greater than or equal to 2 g/cm 3 , and a thickener,
the dispenser making it possible to deliver the at least two base products in adjustable proportions, the viscosity of the first base product being greater than 2 Pa·s,
wherein the thickener of the first base product is chosen from rubber saccharide compounds, and wherein a mass content of the thickener in the first base product is from 0.1% to 5% relative to the total mass of the first base product.
2. The system as claimed in claim 1 , wherein the viscosity of the first base product is greater than or equal to 4 Pa·s.
3. The system as claimed in claim 1 , wherein the second base product has a viscosity less than that of the first base product.
4. The system as claimed in claim 3 , wherein the second base product has a viscosity less than or equal to 1 Pa·s.
5. The system as claimed in claim 1 , wherein the density of said particles is greater than or equal to 5 g/cm 3 .
6. The system as claimed in claim 1 , wherein the particles comprise at least one selected from the group consisting of bismuth oxychloride, cerium oxide, chromium oxide, zirconium oxide, iron oxide, titanium oxide, talc, calcium carbonate, silica, boron nitride, and tungsten carbide.
7. The system as claimed in claim 1 , wherein the second base product does not have any particles with a density greater than or equal to 7 g/cm 3 .
8. The system as claimed in claim 1 , which comprises a third cartridge having a reservoir comprising a third base product.
9. The system as claimed in claim 8 , wherein the third base product comprises a thickener different than that of the first base product.
10. The system as claimed in claim 1 , wherein the mass content of the thickener in the first base product is from 0.8% and 2.5% relative to the total mass of the first base product.
11. The system as claimed in claim 1 , wherein the at least two cartridges are received in a removable manner in the dispenser.
12. The system as claimed in claim 1 , wherein each base product leaves each cartridge through an outlet passage of each cartridge, the outlet passage being defined by a dispensing end piece of each cartridge, said end piece being driven in rotation relative to a body of each cartridge by a drive mechanism of the dispenser in order to dispense each base product contained in each cartridge.
13. The system as claimed in claim 1 , which comprises a mechanism for homogenizing the first base product.
14. The system as claimed in claim 1 , wherein the first base product comprises at least 0.1% by mass of particles exhibiting a difference in density of at least 0.5 g/cm3 with the medium which contains them.
