Description

Plant hair dye

Technical Field

The invention relates to a hair dye, in particular to a hair dye which develops color by complexing pure natural plant components with metal ions.

Background

The most important hair dyes in the market at present are oxidative hair dyes (also called alkaline hair dyes), and the dyeing components of the hair dyes are oxidation dyes such as phenylenediamine or derivatives thereof. The hair dye has the advantages of good hair dyeing effect, long duration and the like, and is the most widely applied hair dye at present. The mechanism of the hair dyeing effect of the hair dye is that during hair dyeing, under the combined action of an alkaline substance and peroxide, dyeing ingredients permeate into fibers in the hair cortex, and are oxidized and polymerized to form macromolecular pigment. The hair color can be maintained for 1 to 3 months because the macromolecular pigment is locked in the hair shaft and is not easy to wash out by water.

Today, the global market for hair coloring agents is rapidly developing, and there are a number of serious problems with such oxidative hair coloring agents, including: 1) wherein, the peroxide hydrogen peroxide is used as a dye oxidant and has irritation and corrosiveness to eyes, skin and mucous membrane with a hair bleaching agent, and when the dye is oxidized, hair keratin is also oxidized, so that the strength and elasticity of the hair are reduced, and hair is rough and branched; 2) the oxidation dye itself, phenylenediamine and some derivatives thereof have the defects of toxicity, sensitization, teratogenicity and the like, are forbidden by some European countries, and the dosage of the p-phenylenediamine and the p-aminophenol is further limited in the technical safety specification (2015 edition) of cosmetics in China.

Along with the increasing importance of people on safety, the requirements of people on hair dyes put more importance on the safety of products, the interest on natural pigment dyes beneficial to human health is increasing day by day, people urgently need permanent natural plant hair dyes which are safe, non-toxic and free from skin allergy, the natural plant hair dyes on the market at present are mostly under the action of strong ammonia water, the irritation taste is heavy, the concept is only a declaration, and chemical components (p-phenylenediamine) are added (such as 'one-time black washing' products on the market). Therefore, a real permanent natural plant hair dye which is safe, non-toxic and does not cause skin allergy is urgently needed.

At present, plant hair dyeing products on the market mostly achieve the effect of dyeing white hair into black hair by a mechanism of complexing plant pigments (such as extracts of gallnut, gallnut and henna) of small-molecular polyphenol tannin components with metal to develop color, for example, patent (CN102198058A) dyes hair by a mechanism of complexing a metal mordant and various plant polyphenol raw materials. The hair dye based on the mechanism adopts natural pigment, so that the risk of body harm caused by p-phenylenediamine chemical dye is avoided. However, most of the plant pigments are small-molecular polyphenol components, and thus the plant pigments are easy to permeate into the hair and fade from the hair with continuous washing, so that the color fastness is low.

Example 10

By using

PRO ultra-high precision professional spectrophotometers tested the hair dyeing effect of the hair dyes (dye + developer) obtained in examples 1-9 by measuring the same hair sample (white) under light source D65 without usingThe hair color value L of the same hair dye is obtained by the same dyeing step at different time periods before and after dyeing. The L value represents the shade of the color, the larger the L value is, the whiter the hair color is, the smaller the L value is, the blacker the hair color is, the L value is generally considered to be 0 and is pure black; the value of L is 100 and is pure white. Generally, hair with L being less than or equal to 16 is considered as black, hair with L being more than or equal to 60 is considered as white, and hair is gray between 16 and 60 (reference: Gaohai Yan. natural hematoxylin pigment hair dyeing performance research. applied chemical industry. 2009,38(10): 1404-1407.). Therefore, the hair dyeing effect is judged according to the L value change. And meanwhile, detecting the washing color fastness for 90 days after dyeing. The results are shown in Table 3.

TABLE 3 Hair dyeing Effect of the Hair dyes of examples 1 to 9

And (3) analyzing a detection result: as can be seen from examples 1-3, when one of tea, sanguisorba officinalis and gallnut is used alone as a dye component, the dyeing effect is general; as can be seen from the comparison of examples 1, 2 and 4, the hair dyeing effect of the combination of the garden burnet and the gallnut is obviously better than that of the garden burnet or the gallnut which is used alone; comparing examples 1, 3, 5, it can be seen that the hair dyeing effect of the combination of tea leaves and gallnut is obviously better than that of the combination of tea leaves or gallnut which is used alone; as can be seen from comparative examples 1 to 6, the hair dyeing effect of the combination of tea leaves, sanguisorba officinalis and gallnuts is the best.

The possible reason is that some macromolecular polyphenols rich in tea and/or sanguisorba are deficient in gallnut. The polyphenol components rich in the tea leaves and/or the sanguisorba also have the hair dyeing effect, and when the tea leaves and/or the sanguisorba are used in combination with the gallnut, the polyphenol tannin components rich in the tea leaves and/or the sanguisorba can make up the deficiency of the polyphenol tannin components in the gallnut, and exert the synergistic effect, so that the better hair dyeing effect is obtained.

In summary, the above embodiments are merely preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
