Background
The wet tissue is a disposable sanitary product, and the wet tissue is widely applied to various occasions along with the improvement of living standard of people, and especially plays an important role in the occasions inconvenient to use water, for example, the wet tissue can be used for wiping faces and hands, so that the wet tissue is sanitary and convenient.
The wet tissue is generally composed of two parts of a substrate and liquid medicine, wherein the substrate is wet-strength paper or spunlace nonwoven, and the liquid medicine basic formula comprises water, humectant, preservative and nonionic surfactant. The preparation method comprises soaking the base material in the medicinal liquid, taking out the base material, and sealing and packaging to obtain the wet tissue.
The preparation of the liquid medicine in the preparation of the wet tissue is the most critical, the common liquid medicine basic formula only has a cleaning function and does not have a function of treating dermatitis, and if the wet tissue is required to have the function of treating dermatitis, a component with the function of treating dermatitis is required to be added into the liquid medicine so as to enable the wet tissue to have the function of treating dermatitis.

Most preferably, the composition for treating dermatitis comprises moutan bark extract and dahurian angelica root extract; wherein the weight ratio of the moutan bark extract to the dahurian angelica root extract is 4: 1.
Preferably, the moutan bark extract is prepared by a method comprising the following steps:
adding water into cortex moutan, performing steam distillation to obtain oil-water mixture, separating oil-water mixture, and collecting water phase to obtain cortex moutan extract; the dosage ratio of the moutan bark to water is 1g: 8-20 mL.
Preferably, the angelica dahurica extract is prepared by a method comprising the following steps:
adding water into radix Angelicae Dahuricae, steam distilling to obtain oil-water mixture, separating oil-water mixture, and collecting water phase to obtain radix Angelicae Dahuricae extract; the dosage ratio of the radix angelicae to the water is 1g: 8-20 mL.
Through a large number of experimental researches, the inventor discovers that the moutan bark extract and the radix angelicae extract prepared by the method have a very good effect of treating dermatitis, and particularly, after the moutan bark extract and the radix angelicae extract are mixed according to the weight ratio of 3-5: 1, the effect of treating dermatitis is more obvious, and a synergistic treatment effect can be generated.
Has the advantages that: the invention provides a composition with a brand-new composition and an effect of treating dermatitis, wherein the composition with the effect of treating dermatitis is a pure natural component, is safe and nontoxic to use, and has an obvious treatment effect.

Example 4 dermatitis treatment experiment
150 patients clinically diagnosed with dermatitis are selected, the age is 18-25 years, and the clinical symptoms are skin pruritus and skin damage. The experimental treatment was performed by randomly dividing 50 patients into 3 groups of 50 persons each. Group 1 was swabbed 3 times a day for 1 minute each time with the composition for dermatitis treatment prepared in example 1 (composition component: moutan bark extract: dahurian angelica root extract =4: 1); group 2 scrubbing with moutan cortex Radicis extract prepared in example 1 3 times a day for 1 minute; group 3 was swabbed with the extract of radix Angelicae Dahuricae prepared in example 1 3 times a day for 1 minute. The effect was counted for 30 days of continuous scrubbing, as shown in Table 1.
The healing standard is as follows: the skin has no pruritus, and the skin lesions completely disappear.
The obvious effect standard is as follows: the skin itch is reduced, and the skin damage is improved.
Invalidation criteria: no improvement in symptoms or worsening of symptoms.
TABLE 1 results of clinical dermatitis treatment
As can be seen from the clinical experimental data in Table 1, the moutan bark extract and the angelica dahurica extract prepared by the method have certain dermatitis treatment effects. Particularly, the composition with the effect of treating dermatitis prepared in the embodiment 1 is prepared by mixing the moutan bark extract and the angelica dahurica extract, the effect of treating dermatitis is more remarkable, after 30 days of treatment, the cure rate reaches 45 cases, and the cure rate reaches 90%. The cure rate of the moutan bark extract used alone is 62%, and the cure rate of the angelica dahurica extract used alone is 48%.
