## Abstract

The invention relates to a system (10) for dispensing a product, comprising a dispenser that can house at least two cartridges, each of which includes a reservoir containing a base product, a first base product comprising at least 0.1 wt.-% particles having a density differential relative to the medium containing same, preferably of at least 0.5 g/cm3, in particular particles having a density greater than or equal to 2 g/cm3, and a thickening agent. The dispenser allows at least two base products to be dispensed in adjustable proportions, the viscosity of the first base product being preferably greater than 2 Pa·s and more preferably greater than or equal to 4 Pa·s.

## Claims

### Claim 1

A system for dispensing a product comprising a dispenser that receives at least two cartridges that each have a reservoir containing first and second base products, respectively, the first base product comprising a moisturizing agent, the second base product comprising a filler, the dispenser making it possible to deliver at least these two base products in adjustable proportions, the mass proportion of moisturizing agent in the first base product being higher than in the second base product, the mass proportion of filler in the second base product being higher than in the first base product, the filler being other than a colored pigment conferring a color on the composition.

### Claim 2 (depends on 1)

The system according to claim 1, the moisturizing agent being chosen from polyols, urea and its derivatives, hyaluronic acid, glycine, β-alanine, taurine, trimethyl glycine, and mixtures thereof.

### Claim 3 (depends on 1)

The system according to claim 1, the particle size D50 by volume of the filler being between 100 nm and 1 mm.

### Claim 4 (depends on 1)

The system according to claim 1, the filler being chosen from talc, mica, silica, kaolin, poly-β-alanine powder and polyethylene powder, tetrafluoroethylene polymer powders, lauroyllysine, starch, boron nitride, hollow polymer microspheres, silicone resin microbeads, polyorganosiloxane elastomer particles, precipitated calcium carbonate, magnesium carbonate, magnesium hydrogen carbonate, hydroxyapatite, barium sulfate, aluminum oxides, polyurethane powders, composite fillers, hollow silica microspheres, and glass or ceramic microcapsules, the particles that are in the form of hollow sphere portions, and mixtures thereof.

### Claim 5 (depends on 1)

The system according to claim 1, the first base product and the second base product comprising an inverse emulsion.

### Claim 6 (depends on 1)

The system according to claim 1, the mass content of filler in the second base product being greater than or to 0.5%.

### Claim 7 (depends on 1)

The system according to claim 1, comprising a third cartridge with a third base product.

### Claim 8 (depends on 1)

The system according to claim 1, the cartridges being received in a removable manner in the dispenser.

### Claim 9 (depends on 1)

The system according to claim 1, each product leaving the cartridge through an outlet passage of the cartridge, the outlet passage being defined by a dispensing end piece of the cartridge, said end piece being driven in rotation relative to a body of the cartridge by a drive mechanism of the dispenser in order to dispense the base product contained in the cartridge.

### Claim 10 (depends on 1)

A method for applying a cosmetic, makeup and/or care, product to human keratin materials, with the aid of a dispensing system according to claim 1, comprising the setting of the dispenser depending on the area to be treated, and the dispensing of the product by base products being picked up from the cartridges in the proportions corresponding to the setting of the dispenser.
