Description
TECHNICAL FIELD
[0001] The present patent application belongs to the field of skin care cosmetics, and in particular, relates to a recombinant collagen-orchid extract composition with good anti-wrinkle and firming effects and a cosmetic using the composition as a raw material. BACKGROUND
[0002] With the improvement of people's living standards, there is an increasing demand for anti-wrinkle and firming effects of cosmetics. Collagen is an important component of the skin, and its reduction will lead to skin relaxation and wrinkle formation. Recombinant collagen, as a new source of collagen, has the advantages of high safety and strong biological activity. In particular, some small molecule peptides from collagen are more easily absorbed by the skin and can more effectively exert their biological activity.
[0003] On the other hand, Calanthe discolor, a rare plant in the Orchidaceae family, has various bioactive components, including phenanthraquinones, alkaloids, and phenolic derivatives, and has antioxidant, anti-inflammatory, and collagen synthesis-promoting effects. Efficacy tests have confirmed that the active ingredients in Calanthe discolor extract can induce adipose-derived stem cells to secrete a secretome rich in growth factors, which can stimulate fibroblasts to synthesize proteins and activate the regenerative capacity of fibroblasts, increasing the synthesis of various growth factors required for communication between fibroblasts and adipose-derived stem cells. Therefore, it can activate the signal communication between adipose-derived stem cells and fibroblasts, increase the synthesis of collagen and elastin, and thus improve skin firmness and elasticity.
[0004] In recent years, with the rapid development of the medical beauty industry, more and more functional recombinant collagens have been developed and applied in various cosmetics. However, how to combine recombinant collagen with other ingredients to better exert its cosmetic and skin care effects has not yet been paid attention to by researchers. SUMMARY

[0006] The inventors have conducted in-depth research on the synergies of various ingredients with anti-wrinkle firming efficacy, and found that: 1. A certain proportion of recombinant collagen type III described in Chinese patent application 201310701942.8 and APG tripeptide have synergistic effect in increasing fibroblast growth factor (b-FGF), thereby better maintaining and restoring skin elasticity, playing an anti-wrinkle firming role. 2. It is found for the first time that LPG tripeptide has the functions of increasing the thickness of the dermis layer of the skin and promoting skin repair, and a certain proportion of recombinant collagen type I described in Chinese patent application 201310701767.2 and LPG tripeptide have synergistic effect in increasing the thickness of the dermis layer of the skin and promoting skin repair. 3.

[0041]
[0042] Mini small molecule peptide-1: APG tripeptide (Ala-Pro-Gly), which was synthesized by a commercial company.
[0043] Mini small molecule peptide-2: LPG tripeptide (Leu-Pro-Gly), which was synthesized by a commercial company.
[0044] Example 1: Effect of each single component and composition on the amount of mouse fibroblast growth factor
[0045] The following reagents were prepared: type III recombinant collagen solution (25 mg / mL, aqueous solution), APG small molecule peptide solutions 1-5 (0.01 mg / mL, 0.1 mg / mL, 1 mg / mL, 5 mg / mL, 10 mg / mL, aqueous solution), compositions 1-5 (type III recombinant collagen 25 mg / mL + APG small molecule peptide 0.01 mg / mL, 0.1 mg / mL, 1 mg / mL, 5 mg / mL, 10 mg / mL, aqueous solution), commercially available recombinant collagen solution (25 mg / mL, aqueous solution), and purified water 100 mL.
[0046] The above solutions were used to group and apply to mice, and the specific steps were as follows:
[0047] After the mice were acclimated and fed for one week, 110 mice weighing 25-30 g were selected, and the remaining hair on the back of the mice was removed in an area of 1.0 x 1.0 cm. The mice were randomly divided into 11 groups, with 10 mice in each group. The purified water group served as the normal group, and the commercially available recombinant collagen solution served as the positive control group. The remaining groups were randomly divided into type III recombinant collagen group, APG small molecule collagen peptide-1 group (0.01 mg / mL), APG small molecule collagen peptide-2 group (0.1 mg / mL), APG small molecule collagen peptide-3 group (1 mg / mL), APG small molecule collagen peptide-4 group (5 mg / mL), APG small molecule collagen peptide-5 group (10 mg / mL), and composition 1-5 group. The mice were applied with the drugs twice a day, with a dosage of 0.2 mL / 10 g, for 4 weeks. Two hours after the last administration, the mice were sacrificed, and the back skin was cut and selected for tissue homogenate to perform ELISA detection to detect the amount of fibroblast growth factor (b-FGF). The b-FGF growth rate of each administration group was calculated.
[0048] b-FGF growth rate = b-FGF amount of administration group / b-FGF amount of normal group
[0049] The combined drug index CI = (A x B) / AB was calculated simultaneously, wherein A and B are the b-FGF growth rates of the type III recombinant collagen group and the APG small molecule collagen peptide 1-5 group respectively, and AB is the b-FGF growth rate of the composition 1-5 group. When CI < 1, it indicates that the combination has a synergistic effect; when CI ≤ 0.9, it indicates that the synergistic effect is significant. The effects of each single component and the composition on the amount of mouse fibroblast growth factor and the combined drug index are shown in Table 1.
[0050] Table 1

[0052] As can be seen from Table 1, the compositions 1-5 of the present application can increase the amount of mouse fibroblast growth factor. At the same time, the combined drug indexes of the compositions 2-4 are all less than 1, indicating that the ratio of recombinant type III collagen to APG small molecule collagen peptide is 250:1-5:1, which has a synergistic effect. In particular, the combined drug index of the composition 3 is less than or equal to 0.8, indicating that the ratio of recombinant type III collagen to APG small molecule collagen peptide is 25:1-5:1, which has a significant synergistic effect. In the skin, type III recombinant collagen can promote the growth of fibroblasts and the secretion of collagen by fibroblasts, thereby maintaining and restoring skin elasticity and playing an anti-wrinkle and firming role. APG small molecule collagen peptide mainly acts as a type of elastin molecule and can promote the growth of dermal fibroblasts. Therefore, the combined effect of the two can greatly increase the number of dermal fibroblasts in the skin, achieving the effect of increasing skin elasticity and anti-wrinkle and firming.
[0053] Example 2: Effects of each single component and the composition on the thickness of mouse dermal layer
[0054] The following reagents were prepared: recombinant type I collagen solution (25 mg / mL, aqueous solution), LPG small molecule peptide solutions 1-5 (0.01 mg / mL, 0.1 mg / mL, 1 mg / mL, 5 mg / mL, 10 mg / mL, aqueous solution), compositions 1-5 (recombinant type I collagen 25 mg / mL + LPG small molecule peptide 0.01 mg / mL, 0.1 mg / mL, 1 mg / mL, 5 mg / mL, 10 mg / mL, aqueous solution), and purified water 100 mL.
[0055] The above solutions were used to group and administer the mice, and the specific steps were as follows:
[0056] After the mice were adapted to the feeding for one week, 130 mice with a weight of 25-30 g were selected, and the residual hair on the back of the mice was shaved in a region with a size of 1.0*1.0 cm. The mice were randomly divided into 13 groups, with 10 mice in each group. Purified water was used as the normal group, and 10% sodium lactate was used as the model group. The rest of the mice were randomly divided into the recombinant type I collagen group, the LPG small molecule collagen peptide-1 group (0.01 mg / mL), the LPG small molecule collagen peptide-2 group (0.1 mg / mL), the LPG small molecule collagen peptide-3 group (1 mg / mL), the LPG small molecule collagen peptide-4 group (5 mg / mL), the LPG small molecule collagen peptide-5 group (10 mg / mL), and the composition 1-5 groups after being treated with 10% sodium lactate for 7 days. The mice were administered with the drugs twice a day, and the administration amount was 0.2 mL / 10 g, which lasted for 4 weeks. Two hours after the last administration, the mice were sacrificed, and the skin on the back was cut and selected to prepare tissue sections. The dermal layer thickness was measured, and the dermal layer recovery coefficient of each administration group was calculated.
[0057] Dermal layer recovery coefficient = dermal layer thickness of the administration group / dermal layer thickness of the model group
[0058] The combination index CI = (A x B) / AB was also calculated, where A and B were the dermal layer recovery coefficients of the type I recombinant collagen group and the LPG small molecule peptide-1-5 group, respectively, and AB was the dermal layer recovery coefficient of the composition 1-5 group. When CI < 1, it indicated that the combination had a synergistic effect. When CI ≤ 0.9, it indicated that the synergistic effect was significant. The dermal layer recovery coefficients of each single component and the composition 1-5 and the combination index are shown in Table 2.
[0059] Table 2

[0061] As can be seen from Table 2, compared with the 10% lactic acid damage group, the compositions 1-5 of the present application can restore the dermis layer thickness of the mice. Meanwhile, the combination index of the compositions 2-4 is less than 1, indicating that the recombinant collagen type I and the LPG small molecule peptide have synergistic effect in restoring the dermis layer thickness when the ratio is 250:1-5:1. In particular, the combination index of the compositions 3 and 4 is less than 0.9, indicating that the recombinant collagen type I and the LPG small molecule peptide have significant synergistic effect in restoring the dermis layer thickness when the ratio is 25:1-5:1. In the skin, the recombinant collagen type I mainly plays a role in the form of collagen fibers, which not only endows the tissue with flexibility and tear resistance, but also promotes the growth of epithelial cells and promotes skin repair. On the other hand, no report is found about the function of the LPG small molecule peptide, and the present application first discovers that the LPG small molecule peptide has the functions of increasing the dermis layer thickness of the skin and promoting skin repair. Therefore, the present application also provides the use of the LPG small molecule peptide in the preparation of cosmetics for increasing the dermis layer thickness of the skin and promoting skin repair. The change of the dermis structure is the main internal physiological reason for skin aging. Studies have shown that the dermis thickness becomes thinner after skin aging. The above study of the present application shows that the combination of the recombinant collagen type I and the LPG small molecule peptide can synergistically increase the dermis layer thickness of the skin, thereby playing an anti-wrinkle and firming effect.
[0062] Example 3 Product Efficacy Test One
[0063] As an example of raw materials, a recombinant collagen composition was prepared, which comprises: the recombinant collagen type I, the recombinant collagen type III and the Mini small molecule recombinant collagen peptides APG and LPG, wherein the weight ratio of the recombinant collagen type III to the Mini small molecule recombinant collagen peptide APG is in the range of 10:1-100:1, and the weight ratio of the recombinant collagen type I to the Mini small molecule recombinant collagen peptide LPG is in the range of 10:1-100:1.
[0064] As another example of raw materials, on the basis of the above-prepared recombinant collagen composition, an orchistem extract composition (Orchistem TM , a product of Provital Company) was added, so that the ratio of the sum of the weights of the recombinant collagen type III, the recombinant collagen type I, the APG tripeptide and the LPG tripeptide to the weight of the orchistem extract is 400:1-50:1, thereby preparing a recombinant collagen-orchistem extract composition. The same amount of the above-mentioned recombinant collagen composition raw material, the above-mentioned recombinant collagen-orchistem extract composition raw material and a commercially available collagen composition were respectively used as the only efficacy component, and the same production process was used to make a face cream, which was used in the following product efficacy test.
[0065] The volunteers were applied with the above cream for test, and the specific steps were as follows:
[0066] Forty-three volunteers aged 25-45 years old were recruited, and the initial dermal density and elastic fiber content of the left and right faces were tested after cleansing as the test results of day 0. Three 3x3 cm areas were selected on the left and right faces, respectively. The left face was applied with the above prepared cream containing the commercial collagen composition as the control group, and the right face was applied with the above prepared cream containing the raw material of the recombinant collagen composition or the raw material of the recombinant collagen-extract of Phrymaceae composition as experimental group 1 or experimental group 2, respectively. After two times a day, no other skin care products were used, and the test period lasted for 28 days. The amount used each time was 2 mL.
[0067] The skin ultrasonic diagnostic instrument (model: Ultrascan UC22) produced by Germany CK Company was used to determine the operation according to the instructions of its product manual, and the dermal density improvement rate, skin elastic fiber improvement rate, collagen fiber harmonic intensity improvement rate and aging index improvement rate on the 14th day and the 28th day were calculated based on day 0. The results are shown in Tables 3-6.
[0068]
[0069] Among the above indexes, the higher the dermal density value, the higher the content of collagen and elastic fiber in the dermal layer. The higher the elastic fiber fluorescence intensity value, the better the skin elasticity. The higher the collagen fiber harmonic intensity value, the better the skin condition. The lower the aging index ELCOR value, the younger the skin condition.
[0070] With the increase of age, the collagen and elastic fiber of the skin will gradually be lost, leading to skin relaxation, sagging, no longer tight, and appearance of aging performance. The product of the application can promote the generation of collagen and elastic fiber, increase the density of the dermal layer, make the skin keep tight and more elastic, and thus present a more young state.
