Embodiment 1

[0397] Example 1 : Preparation of microcapsules A with inner brown coating and outer white coating

[0398] Mannitol (spray-dried mannitol: Pearitol 100SD) was used as the core.

[0399] 120.0 g of ceramide (ceramide PC 104) and 120.0 g of hydrogenated lecithin (lipid S100-3) were added to a mixed solution of 3200.0 g of ethanol, and were completely dissolved at 40°C. 1260.0 g of iron oxide yellow, 252.0 g of iron oxide red, and 45.36 g of iron oxide black were added to the resulting mixture, and sufficiently dispersed using a homogenizer to prepare an internal color coating solution.

[0400] 347.70 g of mannitol was introduced into a fluidized bed coating system (Glatt GPOG 1, bottom spray) as a seed crystal, and then coated with the internal color coating solution at a feed rate of 500 Ml / h to obtain a coating with Granules of the mannitol core of the inner color layer.

[0401] Thereafter, 36.0 g of ceramide and 36.0 g of hydrogenated lecithin were added to a mixed sol...

Embodiment 2

[0404] Example 2 : Preparation of microcapsule B with inner brown coating and outer white coating

[0405] Prepared by fluidized bed process as in figure 1 Color-changing microcapsules with a core and two layers shown in (according to a process similar to Example 1):

[0406] (1) Component: core seed crystal - inner color layer - TiO 2 granular layer

[0407]

[0408]

[0409] Percentages represent percent by weight relative to the total weight of the microcapsules.

[0410] Composition O / W Emulsion

Embodiment 1 and Embodiment 2

[0411] Embodiment 1 and embodiment 2 (according to the present invention):

[0412] Compositions comprising gemini surfactants in the form of O / W emulsions:

[0413]

[0414]

[0415] (1) from SASOL h

[0416] (2) from DOW CORNING PMX-200 silicone fluid 5CS

[0417] (3) from DOW CORNING PMX-1503 fluid

[0418] Preparation scheme:

[0419] Phase A

[0420] 1. Prepare phase A1 in a separate Becher, dissolve and homogenize at 75°C (Rayneri with propeller blades).

[0421] 2. Introduce phase A2 into phase A1.

[0422] Phase B

[0423] 3. Prepare phase B1 in a Becher, make the phase homogeneous (Rayneri with toothed propeller).

[0424] 4. Introduce phase B2 into phase B1 and allow the mixture to expand.

[0425] 5. Place the Becher in a water bath (Moritz-) at 72°C to obtain phase B.

[0426] 6. Phase A (molten) is gradually introduced into aqueous phase B.

[0427] 7. Allow the mixture to emulsify during 10 minutes.

[0428] 8. Add microcapsules (p...

Abstract

The instant invention relates to a changing color composition for caring for and / or making up keratin materials on the form of an O / W emulsion comprising, in a physiologically acceptable medium, at least microcapsules containing releasable colorant(s), at least one gemini surfactant. The instant invention also relates to a cosmetic process for caring for and / or making up keratinic materials.

Description

technical field [0001] The present invention relates to color-changing compositions in the form of oil-in-water (O / W) emulsions comprising gemini surfactants, especially for the care, hygiene and / or makeup of keratinous materials. [0002] In particular, the color-changing composition according to the invention may be any type of cosmetic composition, such as foundations, lipsticks, lip glosses, eyeliners, mascaras, body cosmetics, skin coloring products, skin care products such as skin creams, 'BB' products ( Concealer products that cover imperfections), tinted creams or sunscreen products, preferably foundation or BB products. The color-changing composition according to the invention may be liquid or solid, in particular liquid. [0003] The compositions of the invention are especially compositions intended to be applied to keratinous materials, especially the skin, more particularly the facial skin. Background technique [0004] Cosmetic compositions, especially foundat...
