Embodiment 1
[0073] Example 1: Evaluation of the stability of substance P according to the content of antioxidants and surfactants
[0074] Before preparing a composition including substance P for improving skin wrinkles or inflammation, the present inventors examined the antibacterial properties suitable for cosmetic compositions by conducting an evaluation test of the stability of substance P according to the content of antioxidants and surfactants. Optimal content of oxidizing agents and surfactants.
[0075] To substance P, sodium thiosulfate was added as an antioxidant by varying its content (0.05%, 0.1%, 0.5% and 1%), by varying its content (0.003%, 0.006%, 0.01%, 0.05% and 0.1 %) Adding polysorbate 80 as a surfactant to prepare respective compositions, the stability of substance P in each of the formulations having different contents of sodium thiosulfate and polysorbate 80 was measured.
[0076] Such as figure 1 As shown in , it was demonstrated that in compositions including 0.1...
Embodiment 2
[0077] Example 2: Preparation of a composition comprising substance P for the improvement of skin wrinkles or inflammation
[0078] A novel formulation was prepared by adding to substance P sodium thiosulfate as an antioxidant, polysorbate 80 as a surfactant, and hydroxyethylcellulose as a thickener. Substance P was synthesized by Fmoc-chemistry (which is a peptide synthesis technique) by solid / liquid phase and purified by high performance liquid chromatography. Finally, substance P with a purity of 85% or greater is used.

Embodiment 3
[0081] Example 3: Investigation of the stability of compositions comprising substance P in culture medium of skin fibroblasts
[0082] The stability of compositions comprising substance P was investigated in dermal fibroblast culture medium. Compositions comprising Substance P (5 μg / ml) prepared according to Table 1 or Substance P (5 μg / ml) dissolved in phosphate buffered saline (PBS) as a comparative example were applied to skin fibroblast culture medium ( FGM, Lonza, USA) for 0 hours, 3 hours, 6 hours, 12 hours and 24 hours, and then measure the content of substance P remaining in the medium over time. The content of substance P was quantified by ELISA using the substance P ELISA kit (Abcam, USA). At this time, the sample applied for 0 hours was used as a control group. The control group was regarded as 100%, and the content of substance P remaining in the medium over time was calculated as a percentage (%).
[0083] As a result, in the group treated with substance P diss...
