Problems solved by technology

In other words, the universality of these dyeing raw materials is too poor
In addition, the coloring ability during dyeing is weak, and it needs to be dyed repeatedly to achieve the desired effect.
[0007] Many natural plants in traditional Chinese herbal medicine in our country, such as gallnut, Polygonum multiflorum, hematoxylin, black sesame, black beans, henna, chamomile, etc., are all derived from nature. Nourishing effect; however, hair dyes developed from these plants alone often have disadvantages such as poor effect, low coloring, and short color duration

Embodiment 1

[0035] A compound hair dye, comprising the following components:

[0036] 4wt% of the melanin precursor represented by formula I; 10wt% of the extract after mixing mulberry, black sesame and black soybean according to the mass ratio of 1:2:1; 2wt% of lipid C12-18 fatty alcohol, C16-18 fatty alcohol 6wt%, cetyl stearyl alcohol 2wt%; Surfactant glycerol stearate 2wt%; Antioxidant ascorbic acid 0.3wt%; Alkaline agent arginine (regulating pH is 9.0) 3wt%; Organic solvent 95 % ethanol 2wt%; thickener hydroxyethyl cellulose 0.2wt%; deionized water balance.

[0037] The effect of the hair dye of Example 1 is to dye keratin fibers, especially human hair, into natural black.

Embodiment 2

[0039] A compound hair dye, comprising the following components:

[0040] Hydrobromide represented by formula II is used as 10wt% of melanin precursor; 20wt% of the extract after mixing mulberry, black sesame, black soybean and Polygonum multiflorum according to the mass ratio of 1:1:1:1; lipid 1,3- Butanediol 2wt%, grape seed oil 4wt%; Surfactant polyoxyethylene-2 ​​stearyl ether 3wt%; Antioxidant isoascorbic acid 0.5wt%; Alkaline agent histidine (regulating pH is 9.0) 6wt%; Organic solvent ethylene glycol 1wt%; thickener xanthan gum 0.1wt%; deionized water balance.

[0041] The effect of the hair dye of embodiment 2 is that keratin fibers, especially human hair, are dyed black to jet black.

Embodiment 3

[0043] A compound hair dye, comprising the following components:

[0044]The hydrochloride shown in formula II is used as the precursor of melanin 6wt%; the extract of peony, lotus root, gallnut, hematoxylin and Polygonum multiflorum is mixed according to the mass ratio of 1:1:1:1:1 2wt%; lipid glycerol 2wt% %, isopropyl palmitate 4wt%, synthetic squalane 6wt%; surfactant polyoxyethylene-2 ​​stearyl ether 3wt%, glycerol stearate 2wt%; antioxidant sodium sulfite 0.2wt%; alkaline agent Monoethanolamine (adjusting pH to 9.0) 10wt%; organic solvent hydraulic propane 5wt%; thickener xanthan gum 0.3wt%; deionized water balance.

[0045] The effect of the hair dye of embodiment 3 is that keratin fibers, especially human hair, are dyed black to jet black.

Abstract

The invention relates to a compound dosage-form hair dye which is prepared from a melanin precursor and a natural plant extract, wherein the melanin precursor is a compound shown in a formula I or a halogen acid salt shown in a formula II; the natural plant extract is selected from one of 1) any one or two and more than two extracts of mulberry, black sesames, black soya beans, hematoxylin, polygonum multiflorum root, radix paeoniae lactiflorae, lotus roots and Chinese gall, and 2) any one or two and more than two extracts of henna, neutral henna, dark henna, chamomile, black tea, cutch, salvia japonica Thunb, sandalwood, alder tree bark, haematoxylum campechianum, sand grass and alkanna tinctoria roots.

Description

technical field [0001] The invention relates to a hair dye, in particular to a composite hair dye, which belongs to the technical field of special cosmetics. Background technique [0002] Hair dyes refer to special-purpose cosmetics that can change the color of hair and dye hair into different shades and colors. The properties of raw materials used in hair dyes play a decisive role in the safety and dyeing effect of hair dyes. The development of safe and efficient hair dyes is the demand of consumers and the market. Starting from the 1990s, starting from the melanin in the human body itself and its internal formation mechanism, the development of new raw materials with commercial value and safe hair dyes has become a trend. [0003] Natural melanin (melanin) is an endogenous substance widely present in organisms. Melanin in animals and black human hair are all produced by the biochemical catalysis of copper tyrosinase in melanocytes. The amino acid of the hydroxyl group i...
