Detection test
Preparation of test samples: 10 natural white hair strands selected from the same source were dyed with a hydrogen peroxide solution having a mass concentration of 6% by using the hair dyes of the above examples and comparative examples of the present application, respectively, and the hair strands had a length of about 10cm and a weight of about 5g.
The specific hair dyeing process is as follows: 3mL of the hair dye of each of the above examples and comparative examples and 3mL of a hydrogen peroxide solution having a mass concentration of 6% were taken at room temperature of 25℃and humidity of 75% at a ratio of 1:1, uniformly coating the mixture on the corresponding hair bundles, waiting for 20min, continuously cleaning the hair bundles for 3 times by adopting 60mL of clean water, and kneading 20 times by using 20mL of clean water each time. After the cleaning is finished, the towel is used for sucking up the moisture until the hair bundles are not dripped, and then the hair bundles are naturally dried.
Test 1
Detecting ammonia water residue of hair bundle
50mL of clear water and 3 drops of methyl orange indicator at a mass fraction of 0.1% were each added to the Erlenmeyer flask. The hair tresses were suspended in a conical flask and sealed, after 12h of standing, the tresses were removed and titrated with 0.2moL of hydrochloric acid solution until the colorless solution in the conical flask suddenly changed to orange-red, the titration was stopped, and the amount of hydrochloric acid solution used was recorded in table 1.

The tensile strength value (N) of the hair bundle sample which was not dyed was measured by a push-pull tester and was recorded as an initial tensile strength value, and then 10 hair test hairs were randomly extracted from each of the dyed hair bundles, and the tensile strength change rate (%) = [ (initial tensile strength value-tensile strength value)/initial tensile strength value ]. Times.100% was calculated, and the smaller the tensile strength change rate (%) was, the smaller the damage of hair to hair was proved, and the test results were recorded in table 1.
Table 1:
it can be seen that the hair dyes of examples 1 to 6 have good hair damage reducing effects, ammonia water residue reducing effects and coloring effects by combining examples 1 to 6 and comparative examples 1 to 4.
Specifically, in combination with the analysis of example 3 and comparative examples 1 to 3, the difference between comparative examples 1 to 3 and example 3 is that example 3 was added with sodium polyaspartate, ginseng root extract and wound-healing villus flower extract, and the effect of reducing hair damage, the effect of reducing ammonia water residue and the coloring effect of example 3 were all better to some extent. From this analysis holds that this application is through adding polyaspartic acid sodium, ginseng root extract and treating injury villus flower extract simultaneously in the hair dye, the three is under good cooperation effect, can still promote the better entering of dyestuff between the hair scale and the cortex layer under the less circumstances of hair scale degree of opening, improve the coloring effect of hair, still have unexpected effect of reducing the residual quantity of aqueous ammonia on the hair, can promote the elution of the residual aqueous ammonia of adhesion on the hair scale, between hair scale and the cortex layer, further reduce the remaining ammonia peculiar smell on the hair after the hair dyeing and reduce the lasting harm of residual aqueous ammonia to hair, further improve the use experience of hair dye.
The difference between examples 4-6 and example 3, which were analyzed in particular in combination with example 3 and examples 4-6, is that the acid modifiers of examples 4-6 were malic acid, maleic acid and glycolic acid, respectively, and the hair damage reducing effect, ammonia water residue reducing effect and coloring effect of example 3 were all better to some extent. The applicant considers from this analysis that, through the simultaneous addition of malic acid, maleic acid and glycolic acid, the effect of better reducing the damage of ammonia water to hair scales is achieved, and sodium polyaspartate, ginseng root extract and wound-healing villus flower extract can also be better matched, so that the residual quantity of ammonia water on hair is further reduced, the elution of residual ammonia water adhered on hair scales and between hair scales and leather layers is further promoted, the residual ammonia odor on hair after dyeing is further reduced, and then the data analysis of a color difference value delta E is specifically combined, the coloring effect of the hair dye can be further improved to a certain extent by compounding malic acid, maleic acid and glycolic acid.
