Embodiment 1

[0462] Example 1 : Preparation of microcapsules A with inner brown coating and outer white coating

[0463] Mannitol (spray-dried mannitol: Pearitol 100SD) was used as the core.

[0464] 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.

[0465] 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 50 Ml / h to obtain a coating with Granules of the mannitol core of the inner color layer.

[0466] Thereafter, 36.0 g of ceramide and 36.0 g of hydrogenated lecithin were added to a mixed solu...

Abstract

The invention relates to a changing colour cosmetic composition in an emulsion form and a cosmetic process. A changing colour composition for caring for and / or making up keratin materials in a form ofan emulsion comprises, at least: a) microcapsules containing one or more releasable colorant(s), said microcapsules comprising: a core comprising one organic material, at least one layered coating surrounding said core, the layered coating comprising at least one polymer and at least one colorant; b) at least partially neutralized, crosslinked acrylic homopolymers or copolymers. The core comprises at least one monosaccharide-polyol as said organic material. The microcapsules comprise at least two layers of different colour surrounding the core. The core does not contain colorant material. Theat least one layered coating surrounding the core includes at least one hydrophilic polymer selected from starch. Further disclosed is a cosmetic process for caring for and / or making up keratinic materials.

Description

[0001] This application is a Chinese patent application dated March 05, 2014, application number 201480012561.1, and the title of the invention is "Color-changing composition in emulsion form comprising partially neutralized cross-linked acrylic acid homopolymer or copolymer" Divisional application. technical field [0002] The present invention relates to a color-changing composition in the form of an emulsion, especially for the care, hygiene and / or makeup of keratinous materials, said color-changing composition comprising a specific stabilization system. [0003] 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 c...
