- the dispersion according to Example 1 in particular its hue and its coverage, remains stable (in particular absence of dephase, opacification, change of color) after 3 months at ambient temperature and atmospheric pressure. This dispersion therefore has satisfactory sweat and moisture resistance properties.
- the drops having a diameter greater than or equal to 150 ⁇ represent a volume greater than or equal to 60%, or even greater than or equal to 70%, of the total volume of the dispersed phase and at least 60% of the drops have an average diameter greater than or equal to 150 ⁇ , or even greater than or equal to 250 ⁇ .
- Example 2 describes two compositions 2A and 2B whose respective compositions (fluids) are as follows:
- OIL PHASE ( IF) 100.00 B 100.00 B
- composition 2 A For the IF of composition 2 A:
- B1 DUB ININ A, DUB 81 OC / MB and NIKKOL MEADOWFOAM OIL are mixed at room temperature for 5 minutes.
- B2 The Estogel M is then added to B1. The dispersion is then stirred for 30 minutes with a pale deflocculator at 80 ° C until homogenization.
- a solution for increasing the viscosity (BF) of the continuous phase so as to improve the suspension of the dispersed phase drops in the continuous phase, in particular as described in WO2015055748.
- This BF is in particular a soda solution (NaOH).
- composition 2B are identical to those of example 1.
- the drops having a diameter greater than or equal to 150 ⁇ represent a volume greater than or equal to 60%, or even greater than or equal to 70%, of the total volume of the dispersed phase and at least 60% of the drops have an average diameter greater than or equal to 150 ⁇ , or even greater than or equal to 250 ⁇ .
- Example 2 in particular dispersion 2A, provides information on the properties of Estogel, in particular:
- compositions 3A, 3B and 3B described below are obtained by means of a microfluidic process as described in FR1857625, the composition of the respective phases (fluids) of which are as follows:
- compositions 3A, 3B and 3C are collected. From these samples and using the cellSens software, the diameter of 30 drops was measured under a microscope.
- Figure 1 shows the drop size distribution of these compositions 3A, 3B and 3C.
- composition 3B This comparative example confirms that the use of pigments in the fatty phase of a dispersion according to the invention leads to a decrease in the size of the drops compared to the same dispersion but devoid of pigment (composition 3A).
- composition 3C makes it possible to compensate for the decrease in drop size (observed with composition 3B, or even makes it possible to achieve a drop size greater than that obtained for composition 3A.
