1. experimental animals: the number of healthy adult white rabbits, 33, females, 1.8-2.2kg, is divided into 11 groups of 3.

2. The experimental steps are as follows:

adapting the environment of a healthy adult white rabbit in an experimental animal house for 12 hours; both eyes of the test animals were examined (including examination with sodium fluorescein) within 24 hours before the start of the test. Animals with symptoms of eye irritation, corneal defects, and conjunctival lesions cannot be used for the test.

The lower eyelid of the rabbit's eye was gently pulled open, and 0.1mL of the composition was instilled into the conjunctival sac, and the upper and lower eyelids were passively closed for 1s to prevent loss of the test substance. The other eye was not treated as a self-control. The test subjects were instilled into the eyes of rabbits for 3 minutes, and then rinsed with a sufficient amount of water at a relatively rapid flow rate without causing damage to the eyes of animals for at least 30 seconds, and then examined and scored as shown in Table 1, and the eye irritation response grade of the products was judged as shown in Table 2.

TABLE 1

TABLE 2

The results show that the compositions of examples 1-9 of the present application are tested: the scores of cornea, iris, conjunctiva and edema are all 0, and the cornea, iris, conjunctiva and edema are nonirritating; the cleaning product of comparative example 4 appeared in the test: the integral of cornea and iris of the rabbit is equal to 0, the integral in conjunctival fluid is 0.5, and the integral is 0 within 0.5 day, which belongs to microstimulation; whereas the commercial care product of comparative example 5 appeared in the test: the integral of cornea, iris and conjunctiva of rabbit falls to 0 in 5 days, which is light-stimulative. Therefore, compared with the commercial washing and caring products, the composition provided by the application is milder to eyes and skin, has no irritation, and is very friendly to sensitive skin people.

2. Evaluation of antiallergic efficacy

The compositions of examples 1-9 and comparative examples 1-5 were tested for sensitization using the Elson-Morgan method, which comprises the following steps: 0.1mL of 2.5mmol/L CaCl was added ₂ Adding into 0.5mL of hyaluronidase (600U/mL), and maintaining at 37deg.C for 20min; adding the composition0.5mL, heat preservation at 37 ℃ for 20min; adding 0.4mg/mL sodium hyaluronate 2mL, and preserving heat at 37 ℃ for 40min; adding 1mL of acetylacetone solution, heating in boiling water bath for 15min, and immediately cooling with ice water for 5 mm; finally, ehrlich reagent 1.0mL was added, and the mixture was left at room temperature for 60min to develop color, and the absorbance at 530nm was measured. The calculation formula for measuring the inhibition rate of the sample to the hyaluronidase is as follows:

hyaluronidase inhibition ratio (%) = [ (a-B) - (C-D) ]/(a-B) ×100%

Wherein A represents: absorbance of control solution (acetate buffer instead of sample solution), B represents: absorbance of control blank solution (acetate buffer instead of sample solution and enzyme solution), C represents: absorbance of the sample solution, D represents: absorbance of sample blank (acetate buffer solution instead of enzyme solution).

The number of parallel samples for each group of samples was five, and the average hyaluronidase inhibition rate for each group was calculated and recorded in table 3.
