Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and in particular relates to a black hair essence composition and a preparation method and application thereof. Background Art

[0002] As the population ages, the number of people with gray hair increases at a younger age, and the number of people with gray hair increases, the demand for hair dyeing market increases. Widely used permanent hair dyes are mainly composed of aromatic amines and their derivative intermediates and polyphenol coupling agents. After such hair dyes are applied to the hair, the alkaline conditions cause the hair to swell, and the hair colorant aniline molecules penetrate into the cortex of the hair, undergoing a series of oxidation, coupling, and condensation reactions, ultimately forming larger molecules inside the hair, which are enclosed in the hair fibers and dyed. The chemical components in the above process can cause scalp irritation, and the sensitizing and carcinogenic effects of aniline substances have always been a concern for consumers.

[0003] Hair dyes without adding aniline are currently a hot topic of research. Such hair dyes are far from what consumers expect in terms of coloring effect and lasting effect. Chinese patent CN102824283 B discloses an environmentally friendly hair care dye and its preparation method, which uses hematoxylin or tea polyphenols as raw materials for preparation, requires 3 doses, and the operation is very cumbersome; Chinese patent CN108743481B discloses a walnut green peel black hair dye and its preparation method. Walnut green peel is rich in natural polyphenol dyeing components with multiple phenolic hydroxyls, which can be complexed with metal ions to change color. The hair dyes mentioned in the above patents all use plant polyphenols to chelate with metal ions to form complexes for hair dyeing. Their adsorption is not reliable. They only adhere to the surface of the hair and do not produce a strong adsorption effect with the hair. 5,6-Dihydroxyindole is an important intermediate of melanin. It was first discovered in plants and is a new type of hair dye ingredient with no toxic side effects. Chinese patent CN113559017A discloses a 5,6-dihydroxyindole hair dye and a preparation method thereof, wherein the hair dye is composed of 5,6-dihydroxyindole and 6-hydroxyindole. At present, although the hair dye containing 5,6-dihydroxyindole is active, it cannot naturally oxidize and darken the hair within a limited time, and when oxidized to form indolequinone, the hydroxyl density is reduced, thereby weakening the binding force with the hair, which leads to poor hair dyeing effect. Summary of the invention

[0004] The purpose of the present invention is to provide a black hair essence composition and a preparation method and application thereof, so as to solve the technical problems in the prior art that the dyeing effect of hair dyes is not obvious, not lasting and has great side effects.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A black hair essence composition, comprising 50-60 parts of hair dye A and 40-70 parts of hair dye B; the hair dye A comprises the following components in percentage by weight: 70-80% water, 5-15% sodium lauroyl glutamate, 3-7% arginine, 3-7% cyclodextrin, 2-6% 5,6-dihydroxyindole, 3-7% polydihydroxyindole, 2-8% camellia seed extract, 5-10% hydroxyethyl cellulose, 1-5% tea polyphenols, 1-5% walnut seed extract, 2-5% angelica sinensis extract and 1-5% black walnut shell extract; the hair dye B is composed of the following ingredients in weight percentage: 80-90% water, 5-10% sodium carbonate peroxide, 2-6% cetearyl alcohol, 1-3% ceteareth-25, 1-3% mineral oil, 1-3% ginseng root extract, 1-3% radix scutellariae extract, 1-3% angelica sinensis extract, 1-3% glyceryl stearate, 0.5-1% etidronic acid and 0.1% phenoxyethanol; Furthermore, the mass ratio of sodium lauroyl glutamate to arginine is 1:0.5-0.8; the mass ratio of camellia seed extract to tea polyphenols is 1:0.5-1; and the mass ratio of ginseng root extract to radix scutellariae extract is 1:1.

[0006] Preferably, the ratio of the Angelica sinensis extract to the black walnut shell extract in the hair dye A is 1:1.

[0007] Furthermore, a method for preparing a black hair essence composition comprises the step of mixing hair dye A and hair dye B.

[0008] Furthermore, the black hair essence composition and the preparation method thereof are used in beauty and hair products.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The present invention can produce a chemical reaction by mixing hair dye A and hair dye B, so that the hair presents a natural black color. The black hair essence composition adopts natural plant ingredients, does not contain chemical ingredients and harmful substances, and is mild and non-irritating to the scalp. Tea polyphenols and other ingredients in hair dye A have antioxidant and anti-inflammatory effects, can reduce the inflammatory reaction of the scalp, and protect the health of the scalp. Ingredients such as ginseng root extract, radix scutellariae extract and angelica sinensis extract in hair dye B have soothing and antipruritic effects. Therefore, the black hair essence composition of the present invention has a good coloring effect and a high degree of comfort in use.

[0010] 2. The present invention innovatively adds the Angelica sinensis extract and the black walnut shell extract in a mass ratio of 1:1 to the hair dye A, and has a good hair dyeing effect. It can improve the problems of unclear dyeing effect, uneven dyeing, and short-lasting dyeing in such hair dyes. The present invention avoids adding phenylenediamine substances with high carcinogenic and sensitizing risks, thereby enhancing the safety of its use. DETAILED DESCRIPTION
