Comparative example 3

A shampoo is sold in the market.

First, performance evaluation

The shampoos prepared in examples 1-3 and comparative examples 1-3 were subjected to the performance test, and the results are shown in table 2.

TABLE 2

As can be seen from table 2, the shampoo formulation of the present invention is fully feasible and meets the relevant national standards, and can increase hair smoothness (i.e., reduce combing work), improve use feeling, and maintain proper foam richness. Compared with the shampoo without the added hemerocallis fulva flower extract and the shampoo with the hemerocallis fulva leaf extract, the dry and wet combing power of the shampoo with the hemerocallis fulva flower extract is small after use, and the combing is easier.

Second, irritation test

The shampoos of examples 1 to 3 and comparative examples 1 to 3 were formulated into a 1% by mass solution with deionized water.

According to the standards of cosmetic eye irritation/corrosiveness chick embryo chorioallantoic membrane tests in the entry-exit inspection and quarantine industry standards, a reaction time method is adopted in the research, chick embryos of 9 days old are subjected to egg-lighting inspection, and the positions of air chambers are marked on the surfaces of eggshells; the marked eggshell portion was stripped with dental saw bent forceps to expose the white eggshell membrane. Sucking a proper amount of NaCl solution with the mass fraction of 0.9% by using a suction pipe to moisten the egg membrane, and pouring out the solution. Carefully remove the intima with forceps to ensure the vascular membrane is not damaged. 0.3mL of the test agent is respectively sucked and dripped on the surface of the chorioallantoic membrane, the time for beginning bleeding, vessel thawing and blood coagulation within 5min is recorded, and video recording and photo taking are carried out during the period.

According to the test of chick chorioallantoic membrane irritation/corrosiveness of cosmetics, a reaction time method, namely an IS (irritation score) method IS adopted as a scoring standard, and the calculation formula IS as follows:

in the formula, secH (bleeding time): the average time in seconds(s) at which bleeding begins to occur on the CAM membrane;

secL (vascular fusion time): the average time to onset of vascular melting observed on the CAM membrane in seconds(s);

secC (clotting time): the mean time to onset of clotting observed on the CAM membrane is given in the classification criteria of the second(s) stimulation score in table 3.

TABLE 3

Stimulation scoring	Irritation classification
		IS＜1	Has no irritation
1≤IS＜5	Light irritation
		5≤IS＜9	Moderate irritation
IS≥10	Strong irritation/corrosion

The irritation results are shown in Table 4, and bleeding is shown in FIGS. 1-2.

TABLE 4

From the above results, it can be seen that the shampoos of examples 1 to 3 and comparative examples 1 to 3 are both light-irritant, and it is seen that the shampoo formula is mild and has little irritation to the scalp, and is suitable for most people, and as can be seen from comparison between examples 1 to 3 and comparative examples 1 to 3, compared with the shampoo without the added daylily flower extract and the shampoo with the added daylily leaf extract, the shampoo with the added daylily flower extract has a smaller irritation score, and it is seen that the daylily flower extract has an effect of relieving the irritation of the shampoo to a certain extent.

Three, DPPH clearance rate

The DPPH clearance of the shampoos of examples 1-3 and comparative examples 1-3 were determined separately. 2.0X 10-4mol/L DPPH in absolute ethanol, measurement of the absorbance of blank DPPH (A0): transferring 4mL of absolute ethyl alcohol, adding 2mL of DPPH solution, fully mixing, and measuring the absorbance of the solution at 517 nm; measurement of DPPH + shampoo sample absorbance (A1): respectively transferring 2mL of sample liquid with a certain concentration, adding 2mL of DPPH solution, transferring 2mL of absolute ethyl alcohol, fully mixing, reacting for 30min at room temperature in a dark place, and measuring the absorbance at 517 nm; absorbance (A2) of Hemerocallis shampoo sample was measured by transferring 2mL of the sample solution of the same concentration, adding 4mL of absolute ethanol, mixing, and measuring absorbance at 517 nm. The clearance rate is calculated as follows:

in the formula, A₀: absorbance value of blank control;

A₁: absorbance values of the samples after reaction with DPPH;

A₂: the absorbance values of DPPH were replaced with the same volume of deionized water.

The results of the DPPH radical scavenging ability measurement are shown in Table 5.
