Embodiment 1-4
[0034] Examples 1-4 A combination of high-efficiency soothing, anti-allergic and repairing polypeptides, as shown in Table 1.
[0035] Table 1
[0036]
[0037] Configuration method: Add the carbomer in the formula amount to water and butanediol, stir to mix evenly, let it stand for 24 hours, stir for 5-10 minutes, until a uniform solution without particles, follow the example below 40°C Add the polypeptide uniformly dispersed in polysorbate-20 in sequence with the comparative example, stir evenly, and adjust the pH value to about 5.0 with sodium lactate.
Embodiment 1
[0077] Take Example 1 and Comparative Example 10 polypeptide composition for experimental comparison, and use water as a blank placebo control to evaluate the effect of antipruritic and redness reduction;
[0078] Organize 20 volunteers, respectively apply 20uL of 1% histamine phosphate to the skin area of 3×3cm of the volunteers’ arms, wait for the skin to become red and itchy, and record the time; then drop 0.1% diluted samples of Example 1 and Comparative Example 10 20uL each of the sample and water were placed in the test area, and the red itching subsided time was recorded.
[0079] Test site: inner arm
[0080] Test environment: temperature: 20℃~22℃, humidity: 40%~60%
[0081] Reference basis for skin erythema: GB17149.2-1997 Determination of the degree of reaction of the test site;
[0082] Itching refers to the evaluation and countermeasures of skin itching in patients with skin diseases;
[0083]
[0084] The experimental results are shown in Table 5
[0085]...
Embodiment 2
[0089] Taking Example 2, the commercially available glycerol phosphoinositide choline salt is used for experimental comparison, and water is used as a blank placebo control to evaluate the antipruritic and redness-relieving effects;
[0090] Organize 20 volunteers, respectively apply 20uL of 0.8% histamine hydrochloride to the 3×3cm area of volunteers’ arm skin, wait for the skin to become red and itchy, and record the time; then drop 0.1% diluted sample of Example 2 and glycerol phosphate Each 20uL of the alcohol choline salt sample and water was placed in the test area, and the red itching subsided time was recorded.
