Description

Traditional Chinese medicine hair dyeing agent and using method thereof

Technical Field

The invention relates to a hair dyeing product, in particular to a traditional Chinese medicine hair dye taking eucalyptol as a penetrating agent. The invention also relates to a preparation method and a using method of the traditional Chinese medicine hair dye and application of eucalyptol as a penetrant in the hair dye.

Background

Hair dyeing product A cosmetic capable of changing the color of hair. With the improvement of living standard, hair dyeing has become a fashion choice for people. With the factors of China entering aging society and the like, the method brings a huge market for hair dyes for dyeing white hair into black hair.

At present, most of hair dyeing black products in the market contain aniline hair dyes, and the products are durable due to low cost and strong coloring capability. However, it has been studied that hair dyes containing aniline have some toxicity, and long-term use thereof can cause poisoning and various cancers. On the basis, in view of the safety of products and the increasing importance of people on health and environmental protection, the green and environment-friendly natural plant hair dye is increasingly popular with consumers.

The developed plant hair dye is divided into a semi-permanent hair dye or a permanent hair dye, and the hair dyeing principle is to utilize tannic acid or natural polyphenol in natural plants to be complexed with iron, copper and other ions to synthesize a black dye so as to achieve the effect of dyeing white hair black. However, the tannin molecules in natural plant pigments are larger than the hair cuticle space, and it is generally difficult to penetrate into the hair cortex, and in this case, finding a suitable penetrating agent to promote the pigments to enter into the hair cortex is to achieve the black dyeing effect of the plant hair dye.

For example, in chinese patent CN101229110A, a non-oxidative permanent natural hair-blackening liquid and its preparation method are disclosed, wherein clove, a Chinese herb medicine, is used as a penetrant to make the Chinese herb medicine dye enter the hair cuticle. However, the disclosed hair-blackening water requires heating in use, thereby causing inconvenience in use in daily life. The heating required for such a hair blackening liquid to promote the penetration of the dye into the hair cuticle indicates that the clove function as a penetrating agent has not been very prominent, because the hair dyeing effect can be achieved even without the penetration promoting effect of the penetrating agent under the properly heated use condition for such a natural hair blackening agent. Further, chinese patent CN102366382A describes a plant hair dye using isomeric C10 ethoxylate as penetrating agent and its preparation method, wherein isomeric C10 ethoxylate bonds water and phenols through ethoxy group, and at the same time, it is used as nonionic surfactant to penetrate metal ions and plant extract into fur skin. However, in this patent, since it is necessary to incorporate metal ions and plant extracts into the fur skin separately, the agent A is used by heating at 37 to 42 ℃ for 1 hour, and the agent B is used by heating at 37 to 42 ℃ for 2 hours, so that heating is required for dyeing hair and it takes a long time. Therefore, the coloring can be firmly realized under the heating condition, which is always a difficult point for developing natural plant hair dyes.

In this case, finding a suitable penetrant to promote the penetration of pigments into the cortex of hair and developing suitable dyeing conditions are the key to developing a convenient-to-use blackening agent for long-lasting blackening of white hair.

Therefore, there is still a need to develop a long-lasting plant hair blackening agent which is highly safe and convenient to use.

Detailed Description

The technical solutions of the present invention are described below clearly and completely by the specific embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

As described above, it has been difficult to develop a natural plant hair dye for hair blackening, and a penetrant is usually added to a conventional plant hair dye to promote the penetration of the dye into the surface layer and the inner cortex of the hair, thereby accelerating the migration of the dye into the hair. In the existing reports, cysteine, clove, azone and the like can be used as penetrants in hair dyes to generate certain permeation promoting effects. However, in the case of hair dyes using these penetrants, most of them still require heating of hair to facilitate the penetration process at the time of use. In other words, the penetration enhancing effect is not satisfactory. In addition, the existing plant hair dye does not consider the hair dyeing condition when tannic acid and metal ions act, and does not develop proper conditions to enhance the color fixing effect, so the hair dyeing effect is not durable.

The effective penetrating agent used in the existing plant hair dye is intensively analyzed and researched. The invention utilizes eucalyptol or natural borneol as a penetrant, can realize excellent hair dyeing effect at room temperature, and proves that eucalyptol or natural borneol has good permeation promoting effect.

Various aspects of the invention are further illustrated by the following specific examples, and various advantages of the invention are shown by the following examples. The following examples are intended to illustrate the invention, but not to limit it. In the following examples, all components are commercially available unless otherwise indicated. And all proportions are by weight unless otherwise indicated.

Examples

Example 1: preparation of the traditional Chinese medicine hair-dyeing agent according to the invention

The traditional Chinese medicine hair dye according to the present invention was prepared according to the amounts given in the following table.

The traditional Chinese medicine black hair dye is prepared according to the following steps:

respectively obtaining a dyeing agent matrix and a mordant matrix by simply mixing sodium dodecyl sulfate, guar gum, hydroxyethyl cellulose and deionized water;

mixing the components of the coloring agent in Table 1, adding the coloring agent matrix, heating to 40 deg.C, sealing and stirring for 10min to obtain coloring agent, naturally cooling, and sealing for use.

Mixing the components of the mordant in the table 1, then adding a mordant substrate, heating to 40 ℃, sealing and stirring for 10 minutes to obtain the mordant, naturally cooling, and sealing for later use.

Example 2: use and evaluation of the formulations of the invention

Preparation 1

The coloring agent of the preparation 1 prepared in example 1 was uniformly brushed or combed on the white hair, and a shower cap was put on without heating for about 30 min; then slightly washing with clear water; then, the mordant in the preparation 1 prepared in the example 1 is evenly brushed or combed on white hair, and simultaneously, saturated soda water is sprayed, a shower cap is worn without heating, and after waiting for about 20min, the floating color is washed off.

Preparation 2

And methods of using the above formulation 1.

Preparation 3

The method of using the preparation 1 is used, except that the comb is used for 5-10 min when the coloring agent is applied.

Preparation 4

And methods of using the above formulation 1.

Preparation 5

And methods of using the above formulation 1.

Preparation 6

The method of using the preparation 1 is used, except that the comb is used for 5-10 min when the coloring agent is applied. .

The preparations 1 to 6 achieve good hair dyeing effect and can keep the hair color for 40 to 50 days. Specifically, by using the formulations 1, 2, 4 and 5, excellent hair dyeing effects can be achieved at a waiting time of a coloring agent of about 30min and a waiting time of a mordant of about 20 min. For the formulations 3 and 6, excellent hair dyeing effect was also achieved after polycombing for 5-10 min when the coloring agent was applied, which further confirms that ideal hair dyeing effect can be achieved without softener when eucalyptol and natural borneol were used as penetrants.

In the using method, small soda water is sprayed when the mordant is used, so that the hair dyeing and color fixing effects are greatly enhanced, because the small soda water adjusts the surface environment of the hair small skin to be alkaline, the hair small skin is opened when being alkaline, the alkaline is beneficial to the formation of the ferric tannate solids, the two effects are simultaneously generated, the ferric tannate solids are promoted to be embedded into the gaps between the hair small skins, and the hair dyeing effect is further enhanced. Formulation 2 shows that the same hair coloring effect is achieved when natural borneol is used instead of eucalyptol.

The hair dyeing preparation helps the tannic acid molecules in the dyeing agent to enter the hair cortex without heating. Through the hair dyeing process and the hair dyeing conditions, the tannic acid of the dyeing agent and the metal particles of the mordant are more firmly fixed in hair fur gaps, and the hair dyeing effect and duration are improved. Furthermore, it has been surprisingly found that under alkaline conditions, the attachment of the tannin complex to the hair cuticle space can be further enhanced, and the hair dyeing effect can be further remarkably enhanced.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
