Adopt a kind of natural hair dye and the hair colouring methods thereof of the preparation of plant pigment catechu
Technical field
The present invention relates to a kind of hair dye, be meant a kind of natural hair dye and the hair colouring methods thereof that adopt the preparation of plant pigment catechu especially.
Background technology
The hair dye of producing both at home and abroad is many at present is that major ingredient is made with p-phenylenediamine (PPD) and derivant thereof, and its effect is that p-phenylenediamine (PPD) is through H
2O
2Generate dyestuff and with hair-dyeing, the disadvantage of this hair dye is possible make 0.4~6.3% user skin allergy Deng oxidant, and recent intoxicating, carcinogenesis at a specified future date are arranged.In this case, people have produced keen interest to the hair dyed agent with the natural pigment preparation.Germany patent No.3715326 has described a kind of hair dye that adopts the natural pigment exploitation, this hair dye is formed by two doses, wherein potion contains mantoquita in its medium, and another agent contains red or its hydroxy derivatives hematoxylin of Brazil wood in its medium, and these two doses of substeps impose on hair.The major defect of this hair dye is to have used certain toxic mantoquita as mordant, and simultaneously pH is that 9~10 alkaline medium hair dyeing can damage hair.Chinese patent 1045349A proposes two doses of hair dyes of a kind of novel Lignum Sappan, and wherein potion contains ferrous salt in medium, and another agent contains the natural dye haematein, and these two doses same substeps impose on hair.This hair dye does not use harmful reagent, and does not have noxious substance to generate in the reaction yet, but the hematoxylin price is more expensive.Chinese patent 1283449A has proposed a kind of hair dye of being made by pure plant melanin such as Semen Sesami Nigrum powder, Semen sojae atricolor powder, Ink sepiellae seu sepiae and water, and this hair dye is the impermanency hair dye, can be as required flush away at any time.
Summary of the invention
The object of the present invention is to provide and adopt the plant pigment catechu to prepare a kind of novel natural hair dye and hair colouring methods thereof.This hair dye is formed by two doses, and agent A contains the plant pigment catechu, and agent B contains the ferrous salt mordant.
According to technical scheme provided by the invention, adopt the plant pigment catechu to prepare a kind of novel natural hair dye and comprise agent A and agent B, it is characterized in that agent A comprises plant pigment catechu 3~10%, organic solvent 10~50%, Yu Weishui, its pH value are 5~6; Agent B comprises ferrous salt mordant 1~5%, reduced iron powder 0.2~1.0%, and surfactant 1~10%, thickening agent 1~5%, natural essence 0.1~0.3%, dripping acidulant to pH value is 4~7, Yu Weishui, unit is a percetage by weight.
Organic solvent among the agent A is a kind of in the monomethyl of ethanol, isopropyl alcohol, benzyl alcohol, phenethanol, ethylene glycol, 1,2 monoethylene glycol, single ethyl or single-butyl ether, the propylene glycol.
Ferrous salt mordant among the agent B is any Fe of containing that allows use in the cosmetics
2+Salt, surfactant comprises anion, cation, both sexes or non-ionic surface active agent, thickening agent comprises the one or more combination in Radix Acaciae senegalis, methylcellulose, carboxymethyl cellulose, hydroxyethyl-cellulose, the hydroxypropyl cellulose, acidulant comprises hydrochloric acid, phosphoric acid, acetic acid, lactic acid, Tartaric acid or citric acid, and natural essence can adopt a kind of in lavandula angustifolia essence, jasmine flower essence, the Flos Rosae Rugosae essence.
Agent A and agent B are solution or any degree thickening or liquid or the Emulsion form that adds glue.
Described ferrous salt mordant comprises FeSO
4, surfactant comprises Polyethylene Glycol.
The hair colouring methods of a kind of natural hair dye of described employing plant pigment catechu preparation, it is characterized in that, during hair dyeing, earlier agent A evenly is applied on the clean hair, at room temperature to 50 ℃ following hair dyeing 20~40min, then agent B evenly is applied in hair, behind mordant dyeing 10~20min, hair cleaned dry up, dye the brownish black that the back hair is nature.
The inventor once applied for Chinese invention patent " method of refining powdered catechu dye by film separation technique and colouring method thereof ".Catechu is the Chinese medicine material, have heat clearing away, removing dampness, effect such as antibiotic, antibacterial, and resource is extensive, in Chinese yunnan province, Zhejiang Province, Fujian Province, Taiwan Province, Hainan Province, Guangdong Province, Guangxi autonomous region distribution is arranged all.Catechu pigment main component is catechutannic acid, catechin, epicatechin, catechu red etc.
The organic solvent that is added helps to make the surperficial scale of hair to open, and increases infiltration and the adsorptivity of catechu pigment to hair, and reduced iron powder helps to keep the stable of ferrous salt, prevents its oxidation; Surfactant can increase the uniformity of hair dyeing; Thickening agent can reduce the flowability of hair dye, improves the controllability to dyeing part; Acidulant mainly is to be used for the pH value of regulator B, makes it reach 4~7; Natural essence helps to improve the abnormal smells from the patient that reaches hair dyeing back hair in the hair dyeing process, makes the people joyful.
Hair dye of the present invention has following characteristics: (1) A, B are water formulation for two doses, and keep faintly acid or neutrality, help under the prerequisite of not damaging hair hair to be dyeed; (2) replace synthetic dyestuffs with the plant pigment catechu, do not had to use the reagent that human body is had potential hazard in the preparation, and also do not had noxious substance to generate in the reaction; (3) catechu low price is 1/tens of a haematein, and is with low cost with the hair dye of its exploitation.Therefore, this hair dye has no side effect, safe and reliable, hair dyeing effect good, and low price.
