Problems solved by technology

[0022] The technical hurdles to designing this type of product are, firstly, the difficulty of encapsulating pigments in transparent gels and still maintaining their transparency, secondly, the poor compatibility of microcapsules with water-based transparent gels, and thirdly, microcapsules Hardness: the microcapsules are not easy to break so the feeling of the gel will be dry after application

[0696] I Microcapsules

[0697] In the following, different examples of the preparation of microcapsules according to the invention are described in order to illustrate the invention.

example 1

[0698] Example 1 : Preparation of microcapsules with inner brown coating and outer white coating

[0699] Mannitol (spray-dried mannitol: Pearitol 100SD) was used as the core.

[0700] 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.

[0701] 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.

[0702] Thereafter, 36.0 g of ceramide and 36.0 g of hydrogenated lecithin were adde...

Abstract

A changing color composition in the form of a gel for caring for and / or making up keratin materials is disclosed. The composition comprises in a physiologically acceptable medium, a) from 0.1 to 10% by weight preferably from 0.5 to 10% more preferably from 1 to 5% by weight relative to the weight of the composition of 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 3% by weight, preferably 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 and C2-C8 monoalcohols, and mixtures thereof, and c) at least one hydrophilic gelifying agent.

Description

technical field [0001] The invention relates to a color-changing composition in the form of a transparent gel, 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. [0003] The compositions of the invention are especially compositions intended to be applied to keratinous materials, especially the skin, more particularly the facial skin, for example, skin care or make-up for the face. [0004] According to another embodiment, the composition of the invent...
