Color-deepening hair dyeing composition

By adding raw materials such as specific deepening agents and cross-linking agents to hair dyes, the problem of excessive dosage of chemical hair dyes and low color absorption rate of pure natural hair dyes is solved, achieving saturated color with a small amount of use and improving hair dye fastness. and healthiness.

Problems solved by technology

[0004] The advantage of pure natural hair dye is that it does not harm the body. The disadvantage is that the coloring rate is low, and the color depth of the dyed hair is not full enough. Even if the dyeing is repeated several times, it is difficult to dye a saturated color. Widespread use of natural hair dyes

Embodiment 1

[0074] With 10 parts by weight of chitinase, 20 parts by weight of chitin (relative molecular mass is 3 × 10 5 ~7×10 5 ) degraded to a relative molecular mass of 2.7×10 4 , to obtain a deepening agent.

[0075] 20 parts by weight of the darkening agent was emulsified into an emulsion with 40 parts by weight of an emulsifier (model AEO9, purchased from Jihua Company).

[0076] Weigh 50 parts by weight of indigo, 5 parts by weight of crosslinking agent EH and 1 part by weight of alum and mix them at 20° C. to obtain a mixed solution.

[0077] Use 1 weight part of acetic acid to adjust the pH value of the mixed solution to 4-5.

[0078] The emulsion is mixed with the pH-adjusted mixture at 20° C. to obtain a darkening hair dyeing composition.

Embodiment 2

[0085] Silicone resin with a refractive index of 1.3868 (purchased from Shandong Dayi Company) was used as the darkening agent.

[0086] 30 parts by weight of the darkening agent was emulsified into an emulsion by using 35 parts by weight of an amino silicone oil emulsifier (an environmentally friendly emulsifier whose model is EXG-101, purchased from Shanghai Zhongcheng Fine Chemical Co., Ltd.).

[0087] Weighed 2 parts by weight of red dye 102, 10 parts by weight of crosslinking agent and 20 parts by weight of dyeing auxiliaries and mixed them at 20° C. to obtain a mixed solution.

[0088] Use 1 weight part of acetic acid to adjust the pH value of the mixed solution to 3-4.

[0089] The emulsion is mixed with the pH-adjusted mixture at 20° C. to obtain a darkening hair dyeing composition.

Embodiment 3

[0095] Organic fluororesin with a refractive index of 1.38 (purchased from Dalian Botai Company) was used as the deepening agent.

[0096] Using 55 parts by weight of emulsifier (simethicone emulsifier 1# or 2#, purchased from Jiangsu Hai'an Petrochemical Factory), 30 parts by weight of the darkening agent was emulsified into an emulsion.

[0097] 2 parts by weight of orange, 10 parts by weight of citric acid and 40 parts by weight of dyeing auxiliaries were weighed and mixed at 20° C. to obtain a mixed solution.

Abstract

The invention provides a color-deepening hair dyeing composition. The color-deepening hair dyeing composition comprises, by weight, 2-98 parts of hair dye, 1-99 parts of color deepening agent, 2-98 parts of cross-linking agent, 2-98 parts of emulsifying agent, 2-98 parts of dyeing auxiliary and 0.1-40 parts of pH (potential of hydrogen) conditioning agent, wherein the color deepening agent is selected from one or more of chitin, chitosan, gelatin, silicone oil and resin, the relative molecular mass of each of the chitin, the chitosan and the gelatin is smaller than 2.7x10<4>, and the refractive index of each of the silicone oil and the resin is smaller than 1.55. The color-deepening hair dyeing composition has the advantages that under the action of the color deepening agent, the cross-linking agent and the like, unsaturated color dyed by the natural hair dye can be deepened, and saturated deep color can be finally obtained, or use amount of the chemical hair dye can be decreased greatly; hair dyeing time can be shortened, hair dyeing temperature can be lowered, injuries to human bodies can be reduced relatively, dyefastness is enhanced, hair dyeing interval is prolonged, and times of hair dye repetition are decreased.

Description

technical field [0001] The invention relates to the technical field of hair dyeing, in particular to a hair dyeing composition for deepening. Background technique [0002] Among chemical hair dyes, oxidative hair dyes are currently used most, which contain more than 20 chemical components, such as p-phenylenediamine. In order to achieve a full dyeing depth effect, p-phenylenediamine is often used in excess during preparation; when used, the amount of hair dye will also increase by 2 to 3 times, and the dyeing time and temperature will also be doubled at the same time. In this way, too much hair dye will be heated after contacting the skin, which will easily cause benzene organic compounds to enter the body through the skin, and long-term repeated effects are not conducive to health. [0003] Nowadays, people are pursuing health, advocating nature, and urgently need safe, non-toxic and non-toxic hair dyes that will not cause skin allergies. Research and development of safe a...
