Problems solved by technology

However, the solution does not seem very promising, because if this type of capsules are introduced in the formulation, the pigments cannot be encapsulated very well and the appearance of the body still seems to be dirty and messy
Therefore, the bladder does not inflate very well and the hard grainy sensation is strongly felt by the consumer

[0737] I Microcapsules

[0738] In the following, different examples of the preparation of microcapsules according to the invention are described in order to illustrate the invention.

example 1

[0739] Example 1 : Preparation of microcapsules with inner brown coating and outer white coating

[0740] Mannitol (spray-dried mannitol: Pearitol 100SD) was used as the core.

[0741] Add 120.0g of ceramide (ceramide PC 104) and 120.0g of hydrogenated lecithin (lipid S100-3) to a mixed solution of 1600.0g of dichloromethane and 1600.0g of ethanol, and dissolve completely 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.

[0742] The mannitol of 347.70g is introduced into fluidized bed coating system (Glatt GPOG 1, bottom spray), as seed, is subjected to then coating internal color coating solution with the feed rate of 500ml / h, to obtain the coating with Granules of the mannitol core of the inner color layer.

[0743] Thereafter, 36.0 g of ceramide and 36.0 g of hydrogenated lecithin were adde...

example 2

[0746] Example 2 : Preparation of microcapsules with inner yellow coating and outer white coating

[0747] Microcapsules were prepared in the same manner as in Example 1, except that 1557.36 g of iron oxide yellow was used instead of the mixed colorant composed of iron oxide yellow, iron oxide red and iron oxide black as the inner color in preparing the inner color coating solution.

Abstract

A changing colour 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 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 5% by weight, more preferably at least 8% by weight and advantageously at least 10% by weight relative to the weight of the composition of an aqueous phase comprising water and at least one compound chosen from polyols, glycols C2-C8 monoalcohols and mixtures thereof, c) non entrapped Ti02, and d) an O / W emulsifier.

Description

technical field [0001] The present invention relates to a color-changing composition in the form of an oil-in-water (O / W) emulsion, 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, face powders, eye shadows, concealer products, blushers, lipsticks, lip balms, lip glosses, lip pencils, eyeliners, eyeliners, Mascara, body make-up, skin coloring products, skin care products such as skin creams, 'BB' products (concealer products capable of covering imperfections), tinted face creams or sun protection products, preferably foundation or BB products. The color changing composition according to the invention may be liquid, solid or powder. [0003] The compositions of the invention are especially compositions intended to be applied to keratinous materials, especially the skin, more particularly the facial skin. Backgr...
