Description

Melanogenesis hair colorant

Technical Field

The present invention relates to a hair colorant, and in particular to a darkening hair colorant.

Background

People tend to be pale as they age because of the pale hair, and so it is always desirable to reduce visual age by dying the white hair back to a dark brown color.

However, the dark brown hair colorant often contains a para-phenylene diamine (PPD) type synthetic dye, and further contains an oxidizing agent such as hydrogen peroxide and a phenol compound. The use of synthetic hair colorants can not only cause allergies, but also risk causing cancer after transdermal absorption. In addition, hair dyed with synthetic hair colorants loses a large amount of protein, water and lipids, resulting in impaired hair quality.

Although humans have tried to use less harmful natural vegetable hair colorants early before using synthetic hair colorants, the main reason for the poor coloring effect (e.g., dark brown after coloring) is rarely used today.

Disclosure of Invention

The invention aims to provide a darkening hair colorant which comprises a plant amino-containing extract and reducing sugar and can color hair.

The darkening pigment hair colorant provided by the invention comprises an amino compound, reducing sugar and an alkaline agent. In the present invention, the protein in the hair and the amino compound in the blacking hair colorant undergo Maillard reaction (Maillard reaction) with a reducing sugar (a carbohydrate) in the blacking hair colorant in an alkaline environment at normal temperature or under heating, and a blackish-black nitrogenous polymer and copolymer melanin (melanoid) are produced, so that the hair can be colored dark brown, not only naturally harmless, but also effectively colored. The above-mentioned Maillard reaction or carbonyl ammonia reaction, can provide special flavor and color for food, have been used in meat processing, food storage, essence production, Chinese medicine research, etc. field extensively.

The darkening pigment hair colorant of the present invention comprises an amino compound, a reducing sugar and an alkaline agent. The amino compound comprises a vegetal amino-containing extract. The vegetal amino-containing extract is selected from vegetal protein, vegetal peptide, amino acid or their combination.

In the present invention, the vegetable protein can produce a darker coloring effect and react more slowly, and secondly the vegetable peptide, the amino acid reacts more rapidly.

Preferably, the reducing sugar is selected from ribose, arabinose, xylose, glucose, fructose, lactose, maltose, oligosaccharides formed therefrom, or combinations thereof. More preferably, the reducing sugar is selected from ribose, arabinose, xylose or a combination thereof, since pentose is easier to perform the quina reaction than hexose. Since the monosaccharide is faster than the reaction rate, it is more preferable that the reducing sugar is selected from glucose, fructose, or a combination thereof.

The plant amino-containing extract in the melanoidin hair colorant is obtained by extracting natural plants. Preferably, the botanical amino group-containing extract is obtained by extracting soybeans, mushrooms, laver, mulberry leaves or a combination thereof. More preferably, the extraction is carried out using a watery wine as solvent.

In order to accelerate the browning reaction, it is preferable that the amino compound further includes at least one first amino acid consisting of the following group: lysine, glycine, arginine and histidine. In addition to the amino compound, arginine may also serve as a basic agent to provide basic reaction conditions, i.e., may also serve as both the amino compound and the basic agent.

Because the rate of browning reactions accelerates as the pH increases, the preferred pH range for the jet-blacking hair colorants of the present invention is from 8 to 9, which facilitates the browning reactions and does not harm the skin. In order to facilitate the browning reaction, the present invention provides alkaline reaction conditions with the alkaline agent. Preferably, the alkaline agent is selected from arginine, triethanolamine, sodium carbonate, sodium bicarbonate or a combination thereof.

In order to adjust the color of hair coloring and to enhance the black-brown hair coloring effect, it is preferred that the jet-blacking hair colorant further comprises a dye booster selected from henna (henna) extract, polygonum multiflorum extract, camellia sinensis extract, coffee bean extract, or a combination thereof. When the black hair coloring effect is to be provided, the dyeing auxiliary can be selected from a mixture of henna extract and polygonum multiflorum extract; when the dyeing auxiliary is used for providing the coffee or brown hair coloring effect, the dyeing auxiliary can be selected from a mixture of Pu' er tea extract and coffee bean extract.

Among them, the dye molecule contained in henna, lawsone, has good affinity with protein, but because it is reddish orange, it cannot dye out black brown alone, and is suitable as dyeing assistant. The lecithin contained in Polygoni Multiflori radix has effects of nourishing blood, regulating nerve and endocrine, supplying nutrition to hair root, promoting the growth of melanin of hair, and making hair black and bright and easy to comb. The Pu' er tea contains protein, amino acid, saccharide, etc., and can generate black color beneficial to hair coloring by the action of alkaline agent. Coffee beans contain aromatic oils, which are darker in color with longer oxidation time, contributing to the hair coloring effect.

For convenience of use, the darkening hair colorant further comprises a base agent for uniformly dispersing and mixing the reducing sugar, the amino compound, the alkaline agent and the dyeing assistant.

Preferably, the weight proportion of the reducing sugar ranges from 2% to 3%, the weight proportion of the amino compound ranges from 10% to 20%, the weight proportion of the alkaline agent ranges from 0.15% to 0.2%, the weight proportion of the dyeing assistant ranges from 5% to 10%, and the weight proportion of the base agent ranges from 66.8% to 82.85%, based on the total weight of the melanoidin hair colorant as 100%.

Preferably, the melanoidin hair colorant further comprises tannin (tannic acid) which reacts with minerals (e.g., iron ions) in the hair to produce a blue-black or green-black color, which contributes to the hair coloring effect. Based on 100 percent of the total weight of the melanoidin hair colorant and 0.5 to 1 percent of tannin by weight, the melanoidin hair colorant can replace part of dyeing assistants.

Preferably, the base is a cream and is prepared at low temperature, under vacuum and in the absence of light (by mixing an oil phase containing an emulsifier and an amino compound with an aqueous phase containing a reducing sugar using a vacuum emulsifier) to avoid the darkening hair colorant from rapidly reacting and becoming ineffective before use.

The blackening hair colorant has the advantages that the blackening hair colorant is natural and harmless, and has a good effect of coloring hair.

Drawings

FIG. 1 is a comparison of a specific embodiment of a melanotropic hair colorant of the present invention before and after use.

Detailed Description

The specific embodiments of the present invention are described in detail as follows:

the plant amino group-containing extract can be obtained by boiling mushrooms such as agaricus bisporus and volvariella volvacea as a raw material at 100 ℃ for 8 hours, extracting the mushroom by reflux extraction, for example, with a hydroalcoholic solution (a volume ratio of water to 95 vol% alcohol is 1: 1, or an alcohol concentration is 20 vol%), naturally fermenting the extract obtained by extraction in a closed environment for 15 days to decompose proteins in the extract, purifying the fermented product by solid-liquid separation to obtain a fermentation broth, removing the alcohol in the hydroalcoholic solution used in the extraction by distillation under reduced pressure, mixing the fermentation broth from which the alcohol has been removed with propylene glycol as a solvent at a volume ratio of 2:1, and performing rotary extraction to obtain a rotary extract, and then performing concentration distillation under reduced pressure to remove water from the rotary extract.

The plant amino-containing extract can be obtained by extracting mushrooms such as Agaricus campestris and Volvariella volvacea, or by extracting other plants (such as semen glycines, thallus Porphyrae, and folium Mori) by the method of "extraction-fermentation-distillation-trans-extraction-distillation".

The darkening agent can be directly applied to the hair and the hair can be quickly colored by the action of hot air (about 40-45 ℃) of a blower to promote the non-enzymatic browning reaction.

[ examples ]

In the examples of the present invention, black coloring experiments were conducted with this melanoidin hair colorant: applied 1 time daily for 3 consecutive days, and allowed to stand at room temperature for 24 hours each time.

The components and the formulation of the embodiment of the invention are shown in the following table 1:

TABLE 1

In Table 1, the plant amino group-containing extract was obtained by extracting soybeans, mushrooms, laver and mulberry leaves (mixing ratio 1: 1: 1: 0.5); the cream is prepared by mixing oil phase (mixed with emulsifier and amino compound) and water phase (mixed with reducing sugar).

In example 1 of the present invention, two experimental groups (experimental group 1 and experimental group 2) and two control groups (positive control group and negative control group) were provided, each group was prepared by spreading 15 hairpieces on aluminum-foil paper, and the measurement and color development were repeated 3 times to obtain an average value of data, and each measurement was performed daily, followed by soaking in 500mL of water, washing for 1 minute, and then air-drying at room temperature.

The experimental group 1 is short hair with the width of 5 +/-2 cm and the length of 7.5 +/-2 cm; the experimental group 2 is long hair with the width of 5 plus or minus 2cm and the length of 15 plus or minus 2 cm; the positive control group is black hair (width 5 + -2 cm, length 15 + -2 cm); the negative control group was hair bleach (black hair was bleached with bleach powder to simulate bleached white hair, 5 ± 2cm in width and 15 ± 2cm in length).

Experiments were conducted using a spectrocolorimeter to measure the lightness (Lux) of the dyed hair and separately investigate the coloring effect of the melanoidin hair colorants on hair at room temperature for different periods of time.

Erecting an instrument: fixing the color spectrometer and the hair piece on a tripod, and erecting the color spectrometer between the halogen lamp and the hair piece to form a straight line. Adjusting the distance between the hair piece and the spectrocolorimeter to be 3-5cm, so that the spectrocolorimeter can clearly observe the hair piece; and the bulb of the halogen lamp was adjusted upward to a position 1m from the spectrocolorimeter and at an angle of 45 degrees obliquely upward, so that the light source could clearly irradiate the hair piece.

The light-splitting color meter detects the reflected light of the hair piece in the direction of 8 degrees, the light is guided to the light-splitting instrument by the optical fiber to capture signals, and the brightness of the hair piece can be obtained after the output is controlled by the driving circuit.

The average data of the obtained brightness versus time are shown in table 2 below:

TABLE 2

Unit: lux (Lux)

From the experimental data of color measurement it can be seen that:

after 1 day of application, the values of the experimental groups were between 30 and 40 (average value for short hair of experimental group 1 was 38, and average value for long hair of experimental group 2 was 35); while the average of the black hair of the positive control group was 89, and the average of the hair bleaching of the negative control group was 10.

The value of the experimental group is between 45 and 65 days after the smearing (the average value of the short hair of the experimental group 1 is 55, and the average value of the long hair of the experimental group 2 is 61); while the average of the black hair of the positive control group was 90 and the average of the hair bleaching of the negative control group was 6.

The values of the experimental groups were between 78 and 90 days after application (average for short hair 80, average for long hair 86); while the average of the black hair of the positive control group was 85 and the average of the hair bleaching of the negative control group was 12.

The same black coloring test as in the above example was carried out using commercially available henna plant hair dyes, and the brightness value was only 30-40 days after the application.

In addition to the above experiments with hair pieces, in addition, a coloring test of hair was actually performed by 30 persons (15 men, 15 women), and as shown by the photograph of actual use in fig. 1, after continuously applying the jet-black hair colorant of the present example for 3 days, a good coloring effect was seen, and the satisfaction reached 80% to 90%, it was apparent that the jet-black hair colorant indeed had a good coloring effect on hair.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
