Description

A kind of natural plant type black hair dye and application method thereof

(1) Technical field

The invention relates to a natural plant type black hair dye and an application method thereof.

(2) Background technology

At present, hair dye has become the most powerful product in the field of cosmetics, and the annual retail sales of hair dye in the world are more than 7 billion US dollars. At present, there are about 60 million silver-haired consumers in my country. With the aging of my country's population structure, the number will be further expanded. Therefore, the domestic hair dye market has also grown rapidly in recent years.

At present, most hair dyes are oxidative hair dyes, and their main raw materials are p-phenylenediamine compounds and quinone compounds, which are oxidized by hydrogen peroxide, perborate or percarbonate, etc., to display black and other colors. However, because oxidative hair dyes contain toxic chemicals, they can damage the hair to a certain extent, and are prone to allergies, causing skin redness, swelling, tingling and other discomforts. Long-term use can even cause cancer.

Therefore, in recent years, nontoxic natural plant type black hair dye has become the research and development focus of people. For example, US4801302 disclosed a hair dye containing hematoxylin and copper salt on January 31, 1989; CN120999ZA introduced a hair dye using sorghum red pigment; A hair dye prepared from Chinese herbal medicines such as Polygonum multiflorum and Mulberry and white wine; CN101164528A introduces a natural hair dye prepared from plant pigment catechu. These hair dyes are non-toxic and safe, but there are still shortcomings such as low pigment uptake, not washing resistance, and unnatural color.

(3) Contents of the invention

The object of the present invention is to provide a kind of natural plant type black hair dye and its application method.

A natural plant-type black hair dye, the black hair dye contains A agent, B agent, and C agent, and the A agent is mainly composed of the following components in mass percent concentration:

Cysteine (or thioglycolic acid, or a combination of both) 3-8%,

Deionized water is 89-97%,

Adjust the pH to 8-12;

Described B agent is made up of the component of following mass percentage concentration:

Iron salt 2-20%,

Ferrous salt 2-20%,

In the natural plant-type black hair dyeing agent of the present invention, the C agent is a natural plant extract, and the natural plant extract consists of parts by mass: 5-8 parts of Chinese gall, 2-3 parts of mulberry fruit, 3-5 parts of black sesame seeds and 1-2 parts of angelica are crushed and mixed, soaked and extracted with deionized water at 40-60°C, after the extraction is completed, filter to remove slag, add deionized water to the filtrate to make the total solution reach 100 part extract, which is natural plant extract.

Specifically, the natural plant-type black hair dye of the present invention, preferably the black hair dye is A agent, B agent, and C agent, and the A agent is composed of the following components in mass percentage concentration: Cysteine (or thioglycolic acid or a combination of both) 5-6%, hydroxyethyl cellulose 2%, the rest is deionized water, and the pH is adjusted to 9-10; the B agent is composed of the following mass percentage concentration Component composition: iron salt 10%, ferrous salt 10%, azone 10%, sodium sulfite 1%, and the balance is deionized water; the C agent is a natural plant extract, and the natural plant extract The mass parts are: 7 parts of gallnuts, 3 parts of mulberries, 4 parts of black sesame, 1-2 parts of angelica, pulverized and mixed, then soaked and extracted with 50 parts of deionized water at 60 °C, after the extraction is completed, filter out slag, the filtrate is supplemented with deionized water to make the total mass of the solution reach 100 parts of the extract, which is the natural plant extract.

Agent A, agent B and agent C of the present invention are independently prepared respectively, and the specific preparation method is as follows:

Agent A: weigh cysteine (or thioglycolic acid or a combination of the two), hydroxyethyl cellulose, add deionized water to 100%, stir until completely dissolved, and after room temperature, oxidize with hydrogen Sodium aqueous solution to adjust the pH to 9-10, inspect and pack.

Agent B: Mix the amount of ferric salt, ferrous salt, azone, and sodium sulfite, add deionized water to 100%, heat to 40°C, stir until completely dissolved into a transparent uniform system, then cool to room temperature, Inspection, packaging.

Agent C: Grind and mix the natural plant gallnut, mulberry, black sesame, and angelica in the amount of the formula, add 50 parts by mass of deionized water to immerse it, heat to 40-60°C, stir for 20-24 hours, and filter out scum. Then add deionized water to the filtrate while stirring to make the total amount of the solution reach 100 parts, which is the natural plant extract, cool to room temperature, inspect and pack.

The using method of the natural plant-type black hair dye: the method is carried out as follows: take 25-70 milliliters of agent A, agent B, and agent C respectively, and specifically determine agent A, agent B, The amount of agent C, agent A, agent B, and agent C do not require the same amount. First apply Agent A evenly on the hair with a small brush, let it stand at room temperature for 5-15 minutes, wash off the residual Agent A with water; then apply Agent B evenly on the hair, and let it stand at room temperature for 8-20 minutes. , wash off the remaining agent B with water; then apply agent C evenly on the hair with a small brush, etc., and let it stand at room temperature for 5-15 minutes, the hair will be dyed black, and the remaining agent can be washed off with water.

Specifically, it is recommended to use the black hair dye of the present invention as follows: first apply Agent A evenly on the hair with a small brush, let it stand for about 10 minutes at room temperature, and wash off the residual Agent A with water; then apply Agent B evenly Apply to the hair and let it stand at room temperature for 8-10 minutes. If the room temperature is low, heat the hair appropriately or extend the standing time, and wash off the remaining agent B with water; then apply agent C evenly on the hair with a small brush, etc. , let it stand at room temperature for about 10 minutes, the hair will be dyed black, and the color will be natural, and the hair will be soft, just wash off the residual medicine with water. Dosage: Generally, use 25ml each of agents A, B, and C for short hair within 10cm, and 70ml each for long hair about 30cm.

The invention uses natural plant extracts as the main component of the hair dye, does not contain chemical substances such as anilines and strong oxidants, and is natural and non-toxic. The hair dye prepared by the invention can penetrate into the hair well, the dyeing speed is fast, and the dyeing rate is greater than 30%; the washing resistance is good, and it can withstand soaping for about 10 times after dyeing; the hair color after dyeing is natural black, Especially in agent B, the content of ferric salt and ferrous salt is 10% best, if it is too small, the color may be brownish, if it is too high, the color is better, but the cost is high. The black hair dye provided by the invention effectively avoids the phenomenon of blue-black and purple-black after some hair dyes are dyed; and because of the addition of extracts such as nutraceutical gall, the hair quality is better, which promotes the hair to absorb nutrients and makes the hair quality more supple.
