Description

Hair dyeing composition and application thereof in preparation of oxidation type hair dye

Technical Field

The invention relates to the technical field of cosmetics, in particular to a hair dyeing composition and application thereof in preparing an oxidation type hair dye.

Background

Hair dyes are a cosmetic product for dyeing hair. In the hair dyeing, the hair dye actually starts from interfacial reaction such as contact wetting and adsorption of the outermost layer of the hair cuticle, and then reaches the hair epithelium and hair marrow through a complex of cell membranes to cause permeation and diffusion phenomena, and in some cases, the hair dye undergoes a "polymerization" reaction, thereby acting on the hair to change the color of the hair. The dyeing can be classified into three types, temporary, semi-permanent and permanent, according to the fastness of dyeing. The permanent hair dye accounts for 70-80% of the whole hair dyeing cosmetic product, and the active ingredients of the permanent hair dye can permeate into hair pith inside hair to form stable larger dye molecules which are sealed in hair fibers, so that the permanent hair dyeing effect is achieved, and the permanent hair dyeing effect can be kept for 1-3 months generally. The action mechanism can be briefly described as follows: the micromolecule dye color developing agent → permeates into the interior of the hair mass → is oxidized by an oxidizing agent → is condensed with a coupling agent to generate the macromolecular dye → is locked in the interior of the hair mass → forms permanent hair dyeing. The permanent hair dyeing agent is mainly an oxidation type hair dyeing product, generally has a two-part type, and consists of a hair dyeing agent I mainly composed of a color developing agent and a coupling agent and a hair dyeing agent II mainly composed of an oxidizing agent. The two agents are separately prepared during production and preparation, and when the hair dye is used, the two agents are mixed and then coated and infiltrated into hair for dyeing. Researches prove that the oxidative hair dye has certain damage to scalp, has large stimulation, is easy to cause skin to generate red swelling, stabbing pain and other discomforts, how to develop the hair dye which is safe, has low stimulation, has no toxic or side effect, has good hair dyeing effect increasingly draws attention of people, and the mild hair dye added with the active ingredients from natural plants has important significance.

CN109833263A discloses a composition for an oxidative hair dye and application thereof, wherein the composition comprises phytosterol, glycyrrhizic acid and salt thereof, hydrolyzed royal jelly protein and purslane extract, and can obviously relieve the stinging feeling of the oxidative hair dye product to the scalp, reduce the generation of erythema and lower the sensitization rate, thereby obviously improving the health state of the oxidative hair dye product to the scalp. It does not simultaneously solve the problem of damage to the hair by hair dyes and does not confirm the relevant dyeing effects, such as fastness of dyeing.

Result detection

(1) Evaluation of dyeing Effect

The first and second agents (developers) of the oxidation dyeing composition were mixed in a ratio of 1:1, and the mixture was applied to evenly dye human hair 12cm long in an amount of twice the weight of the hair. The hair contains about 30% white hair. After 30 minutes, the hair is washed for 1 minute by running water with shampoo, dried by a hair drier, and the color of the dried hair is measured by a spectrocolorimeter (CM-2600 d).

L represents the lightness index of the dyed hair, and the value range is 0-100, wherein the larger the value is, the brighter the color is, and the smaller the value is, the darker the color is.

a represents the value of the color range of red and green after dyeing, the positive value represents red, and the negative value represents green;

b represents the value of the color range of the dyed yellow-blue, positive values represent yellow and negative values represent blue;

and the smaller the value of the delta E is, the closer the color difference is, and the larger the value of the delta E is, the larger the color difference is.

The results are shown in table 2:

TABLE 2

As shown in table 2, the examples include natural effective components of di (hydroxyethyl) soyamine dioleate, hydrolyzed wheat protein, hydrolyzed royal jelly protein, and gentian root extract, which can promote the penetration of the dye intermediate and the coupler into the hair core before the chemical reaction, and delay the reaction rate of the dye intermediate and the coupler after mixing with the oxidizing agent in the second agent, so that the dye intermediate and the coupler have more time to penetrate into the hair core and generate an effective chemical dyeing reaction, thereby exhibiting better dyeing effect than that of the comparative example 1; as can be seen from the a value, comparative example 1 is more deep red; as can be seen from the value of Delta E, the color difference is large when the mixture ratio of the intermediate is changed.

(2) Fastness to washing test

The dyed hair was immersed in the shampoo solution, shaken at 200rpm for 30 minutes with a shaker, rinsed in running water for 1 minute, and then blow dried with a hair dryer, then the difference in brightness value was measured by a spectrophotometer, △ L was calculated, and the fastness of the dyeing was evaluated based on △ L and the values in Table 1, the lower △ L indicates better fastness of the color, the results are shown in Table 3.

TABLE 3

The test data for examples 9-12 and comparative examples 1-5 are shown in Table 4 below:

TABLE 4

As can be seen from the value of △ L, the addition of the composition can prevent the hair from fading and significantly improve the fastness to washing after dyeing.

(3) Real person hair dyeing test and visual inspection dyeing effect

40 volunteers with sensitive skin were divided into 10 groups of 4 persons each, and they were subjected to test dyeing with the oxidative hair dyeing compositions provided in examples 1 to 8 and comparative examples 1 to 2, respectively. The specific operation is that the oxidation hair-dyeing composition of the embodiment 1-8 is adopted to dye the hair of 4 persons in each group, the same oxidation hair-dyeing composition is used for 4 persons in each group, and different oxidation hair-dyeing compositions are used for different groups; then, they were asked to evaluate the degree of improvement of stimulation and scored, and the degree of improvement of stimulation was represented by the height of the average score of 4 persons; dyeing 4 persons per group with the oxidative hair dyeing composition of comparative example 1, 4 persons per group using the same oxidative hair dyeing composition and different groups using different oxidative hair dyeing compositions; they were then asked to assess the degree of improvement in stimulation and scored, with the level of improvement in stimulation being represented by the average score of 4 people.

After dyeing, each group was asked to evaluate the improvement of stimulation at 1-5 and 0.05 minute intervals. They were given a score of 1 when they felt a small improvement in the stimulation and a score of 5 when they felt a significant improvement in the scalp stimulation. Finally, the scores of 4 persons are integrated and averaged, and the calculation result is shown in table 4.

TABLE 4

As can be seen from table 4, the oxidation hair-dyeing compositions prepared in the examples of the present invention can significantly improve the stimulation to the scalp, while the oxidation hair-dyeing compositions prepared without adding natural effective ingredients and using a large amount of ammonia water as an alkalizer (comparative examples 1 and 2) all have strong stimulation to the skin of sensitive users, and the effect is poor; fastness is also best from the viewpoint of visual dyeing effect by using the hair coloring composition together with a certain proportion of the dyeing intermediate.

(4) Evaluation of Hair feel
