The test method comprises the following steps: randomly selecting female with age of 24-32 years, no allergy history, no obvious wound on hand, dark nail or floating skin on nail or both of the above cases; each test sample was tested against three women.

Recording the type of the condition of each female in the early period and the degree grade of the condition; in case types, a is dull and lusterless nail, b is superficial and superficial skin on nail, ab is both cases; of the three women corresponding to each sample specimen, the case types of three persons cannot be all a or all b. The degree scale includes a scale of 0-5, from 0 to 5, with progressively increasing degrees of nail darkening and skin lifting on the nail. After the application for 14 days, the hands feel dry and are smeared, and the degree grade of the corresponding situation is improved after 30 days.

And (3) test results: the results of the armor effectiveness test are reported in table 4.

Table 4 nail protection effectiveness test results

And (3) data analysis: as is clear from the data in Table 4, examples 1-16 exhibited a certain reduction in both dullness and floating of the skin on the nails, and examples 8-16, particularly examples 11-16, exhibited very good results in terms of care. Comparative examples 1 to 5 had little effect on cases a, b, ab.

Comparing all the examples, examples 1-3 have improved a and b cases, examples 4-5 have defined the compounding amount of calcium pantothenate and dimethyl sulfone based on example 3, examples 6-7 have defined the composition of the third conditioning agent based on example 5, and the improvement of a and b cases is improved. Examples 8 to 9 define the combination of dimethyl sulfone and the third conditioning agent on the basis of example 7, and further improve the situation improvement effect. The reasons may be: the fifth conditioner can moisten and permeate the protective film on the nail surface and the skin on the bracket, and promote the entry and absorption of effective components; in addition, the composition of the fifth conditioner can form high-concentration packages, and the effective stable dosage form ensures that the function of the ceramide is optimized.

Examples 10 to 11 define the composition of the fifth conditioning agent on the basis of example 9, and examples 12 to 13 define the combined amount of the fifth conditioning agent and the third conditioning agent on the basis of example 11, thereby further improving the situation improvement effect. Examples 14-16 define a third conditioning agent and a fifth conditioning agent on the basis of example 13, which, with reference to trial 1, can improve the sensory use of the product while achieving an improvement in ab status. The reasons may be: the third conditioner is beneficial to promoting the action and absorption of calcium pantothenate and dimethyl sulfone, and improving the utilization efficiency of effective components; the third conditioning agent, calcium pantothenate and dimethylsulfone can promote the growth of the nail-skin junction, improve the adhesion, and care the skin and nail, thereby achieving the care of the nail and the skin on the nail.

Comparative example 1 and comparative examples 1-5, comparative example 1 did not use a combination of calcium pantothenate, dimethyl sulfone, and a third conditioning agent, and had no improvement effect on a, b, and ab conditions. Comparative example 2 no third conditioner was used, and comparative example 5 replaced the third conditioner with aloe ferox extract, which is a minor improvement to a certain degree of the grade, indicating that the formulation of the third conditioner with calcium pantothenate, dimethyl sulfone can greatly enhance the care of the product for the nail and the skin on the nail. Comparative example 3, which uses no dimethyl sulfone, and comparative example 4, which uses calcium pantothenate, has little effect, indicating that a combination with a third conditioner, based on calcium pantothenate and dimethyl sulfone, has good effect.
