control group
The hair dye composition of example 6, from which the POSS linear polymer surface-functionalized with pyrogallic acid was removed, was subjected to the same conditions as in example 6, to prepare a hair dye free from the POSS linear polymer surface-functionalized with pyrogallic acid.
Example 8
2g of white hair was collected, and the hair dye prepared in example 6 and the hair dye of the control group were used to conduct a smearing test on the sample white hair. The scoring was according to the following criteria:
1 very poor, 2 poor, 3 generally good, 4 good, 5 very good
TABLE 1 example 6 and control Hair dyeing Scale Table
Figure BDA0002678856610000121
Figure BDA0002678856610000131
As can be seen from Table 1 above, the addition of pyrogallic acid to the surface-functionalized POSS linear polymer of example 6 resulted in better color fastness to washing, hair softness, and black coverage than the control, and the effect of the surface-functionalized POSS linear polymer of pyrogallic acid was significant.
Example 9
In order to verify the effect of the hair dye of the present application, hair dye was performed using the hair dye prepared in example 6. In the experiment, 2g of white hair is dipped in the mixture of the agent A and the agent B and is smeared, and the mixture is washed after 30min, and the test temperature is as follows: room temperature 28 degrees celsius.
TABLE 2 dyed hair color data sheet
Figure BDA0002678856610000132
In table 2 above, L, a, b are parameters of the standard international color space diagram, the L value refers to black and white, and the larger the L value, the whiter the L value; the value a refers to red and green, and the larger the value a is, the more red the value a is; the b value means yellow blue, the larger the b value, the more yellow. As can be seen from the above table, the hair dyeing effect of the present invention is good.
The above samples were washed 10 times and then subjected to a color fastness to washing test,
TABLE 3 data sheet of the colorfastness to washing after dyeing
Figure BDA0002678856610000133
Figure BDA0002678856610000141
As can be seen from Table 3, the hair dye has good color fastness to washing and stable and durable hair dyeing effect.
Example 10
In order to verify the ultraviolet protection ability of the hair dye, hair dye comparison was performed using p-phenylenediamine conventional dye, the hair dye prepared in example 6 and the hair dye prepared in the control group;
TABLE 4 UVA and UVB transmittance
Figure BDA0002678856610000142
UVA, UVB and visible light may cause photodamage to hair, the extent of damage varying with wavelength. UVB mainly causes the loss of hair proteins, UVA promotes color change. The ultraviolet protection of hair includes the protection of natural pigments of hair itself and the protection of external products, and can prevent ultraviolet damage by depositing hair dyes on the hair cortex and the cortex, and the ultraviolet protection ability of different dyes is different. The results are shown in the table above using the same uv resistance test method as the fabric.
Thus, compared with the p-phenylenediamine traditional dye, the hair dyed by the POSS linear polymer without pyrogallic acid surface functionalization in the embodiment 6 has certain ultraviolet resistance effect, and the transmittance of UVA and UVB is obviously reduced; the transmittance of UVA and UVB of the linear polymer is further reduced after the POSS linear polymer with the surface functionalized by the pyrogallic acid is added, and the dyed black hair has strong ultraviolet absorption capacity, so that the skin covered by the black hair can be protected.
Example 11
10 volunteers of men and women were randomly searched, and the hair dye prepared in example 6 and the ammonia water-containing hair dye were applied to the ears of the volunteers, respectively, wherein the hair dye was applied to the left ear and the hair dye was applied to the right ear. After 1 hour, more than 80% of the subjects showed varying degrees of itching and irritation in the left ear, but no adverse reaction in the right ear of 20 volunteers. It can be seen that the hair dye of the present invention has no irritation to skin compared to the conventional hair dye containing ammonia water.
