Embodiment 1

[0460] Example 1 : Preparation of microcapsules A with inner brown coating and outer white coating

[0461] Mannitol (spray-dried mannitol: Pearitol 100SD) was used as the core.

[0462] 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.

[0463] The mannitol of 347.70g is introduced into fluidized bed coating system (Glatt GPOG 1, bottom spray), as crystal seed, then with The inner color coating solution was coated at a feed rate of 0 to obtain particles having a mannitol core coated with an inner color layer.

[0464] Thereafter, 36.0 g of ceramide and 36.0 g of hydrogenated lecithin were added to a mixed solution of 1440....

Abstract

The instant invention relates to a colour changing composition in the form of an emulsion comprising, at least: a) microcapsules containing 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, at least one colorant, and advantageously at least one lipid-based material, b) at least partially neutralized, crosslinked acrylic homopolymers or copolymers preferably in a non-particulate form.

Description

technical field [0001] 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. [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 co...
