Embodiment 1

[0428] Prepare the following compositions:

[0429] Cellulose levulinate sold under the tradename CAB-381-0.5 by Eastman Chemical 10 g

[0430] Mica-iron oxide mother-of-pearl sold under the tradename Prestige Soft Bronze by Eckart 10g

[0431] Ethyl acetate 80g

[0432] 0.5 g of the composition is applied to 1 g of clean, dry hair tresses. The tress was immediately dried with a hair dryer at a temperature of 80° C. for 1 minute while combing continuously throughout the drying period. Colored tresses are obtained in which the hairs are separated and the color is shampoo-firm.

Embodiment 2

[0434] Prepare the following compositions:

[0435] 40% isobutyl methacrylate / bis-hydroxypropyl dimethicone acrylate copolymer in isododecane sold under the name Granacrysil BMAS by Grant Industries 25g

[0436] Mica-iron oxide mother-of-pearl sold under the tradename Prestige Soft Bronze by Eckart 10g

[0437] α,ω-Dihydroxylated Dimethicone / Cyclopentasiloxane (14.7 / 85.3) sold under the name DC1501 Fluid by Dow Corning 50g

[0438] Isododecane 15g

[0439] 0.5 g of the composition is applied to 1 g of clean, dry hair tresses. After a dwell time of 2 minutes, the tress is dried with a hair dryer at a temperature of 80° C. for 2 minutes. Colored tresses are obtained in which the hairs are separated and the color is shampoo-firm.

Embodiment 3

[0441] Prepare the following compositions:

[0442] by the National Starch company under the trade name Dermacryl Acrylic acid / isobutyl methacrylate / ethyl methacrylate / n-tert-octylacrylamide copolymer sold by LT 10g

[0443] Mica-iron oxide mother-of-pearl sold under the tradename Prestige Soft Bronze by Eckart 10g

[0444] α,ω-Dihydroxylated Dimethicone / Cyclopentasiloxane (14.7 / 85.3) sold under the name DC1501 Fluid by Dow Corning 40g

[0445] Ethanol 40g

[0446] 0.5 g of the composition is applied to 1 g of clean, dry hair tresses. After a dwell time of 2 minutes, the lock was dried with a hair dryer at a temperature of 80° C. for 2 minutes while brushing the lock during drying. Colored tresses are obtained in which the hairs are separated and the color is shampoo-firm.

Abstract

Method for hair coloring comprises applying a composition comprising one or more hydrophobic film forming polymer, one or more pigments and a volatile solvent on the hair, followed by heating the hair covered by the composition at a temperature of greater than 40[deg] C.

Description

technical field [0001] The present invention relates to methods of coloring hair using hydrophobic film-forming polymers and pigments. Background technique [0002] In the field of dyeing keratin fibers, the practice of dyeing keratin fibers by various techniques using direct dyes or pigments for non-permanent dyeings or dye precursors for permanent dyeings is known. [0003] Non-permanent dyeing or direct dyeing consists in dyeing keratin fibers with dye compositions containing direct dyes. These dyes are pigmented and dyeing molecules that have an affinity for keratin fibers. They are applied to the keratin fibers for the time needed to obtain the desired coloration and then rinsed off. [0004] Standard dyes used are especially dyes of the nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine or triarylmethane type or natural dyes. [0005] Some of these dyes can be used in lightening conditions, which enable the production of coloration that is vi...
