Again, there is a tendency for drops (G2) to become smaller and stronger at 50? C.

(28) Conclusion

(29) The present study shows that the size of the drops (G2) decreases over time while their viscosity/hardness increases (increase of the local concentration of oily gelling agent) when the latter are in the presence of surfactants or compositions comprising them.

(30) This phenomenon is characterized by a compositional maturation resulting in a migration of a part of the oily phase of the drops (G2) to the surfactants located in the continuous phase of the creams. This has the effect of strongly degrading the organoleptic properties of the composition comprising drops (G2).

(31) Given the stability constraints over time required in the cosmetics field, these results show the impossibility of using drops (G2) in conventional cosmetic compositions (i.e. including surfactants).

(77) The manufacture of the drops (G2) is therefore simultaneous with the manufacture of the composition according to the invention. At the end of the manufacture of this composition, a base solution (BFI), identical to that described in Example 2, may be added, preferably microfluidically, so as to enhance the viscosity of the aqueous phase in the composition according to the invention, and thus suspend the drops (G2).

(78) The compositions according to the invention presented in Examples 2 and 3 are particularly advantageous visually and sensorially. Visually, the consumer is faced with compositions comprising drops (G2) visible to the naked eye. On the sensory level, the texture of these compositions is evolutionary. The first moments of application are very aqueous with a marked brittle effect. Then, the feeling evolves towards an oily veil that fades to leave a light and hydrated skin. In parallel, we feel the gelled drops (G2) melt under the effect of spreading which provides an enhanced oily effect.

Example 4: Preparation of a Transparent Composition According to the Invention with Procedure No. 2

(79) The composition of Example 4 differs from that described in Example 3 in that the continuous aqueous phase and the drops (G1) and (G2) are transparent and the oil phase of the drops (G2) is devoid of gelling agent.

(82) 2. Preparation of the Composition According to the Invention

(83) The oil phase (IF2) for drop formation (G2) is described below.

(85) Optionally, the oil phase (IF2) may further comprise at least one gelling agent and/or a coloring agent so as to affect the visual aspect of the drop (G2).

(86) When the IF2 is devoid of gelling agent, the procedure for preparing the composition according to Example 4 differs from that described in Example 3 in that it is carried out at room temperature; wherein this procedure may therefore advantageously require the use of an intermediate fluid (FI) comprising only Isononyl Isononanoate, as described in WO2012/120043.

(87) The flow rates considered (in mL/h) are as follows:

(89) The manufacture of the drops (G2) is therefore simultaneous with the manufacture of the composition according to the invention. At the end of the manufacture of this composition, a base solution (BFI), identical to that described in Example 2, may be added, preferably microfluidically, so as to enhance the viscosity of the aqueous phase in the composition according to the invention, and thus suspend the drops (G2).

Example 5: Example of a Cosmetic Composition

(90) A composition as described in the table below may be prepared according to one of the manufacturing methods described in the present invention and, in particular, according to the method described in Example 3 above.

(92) A composition according to Example 5 may be applied every morning on the face to moisturize, strengthen the barrier function, protect and bring radiance to the skin.

(93) It has been observed that a composition according to Example 5, in use, especially as indicated above, allows prolonged microdiffusion of the active ingredients, in particular moisturizing and anti-aging agents, and in fact provides a continuous action in the heart of the skin.
