Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology and relates to an anti-aging essence containing caviar extract and its preparation method. Background Technology

[0002] Skin aging is an inevitable stage of human life, influenced by genetic factors, environmental factors, and the complex morphological structure of the entire body. In recent years, with the rise of dietary culture and changes in people's lifestyles, many people's skin has begun to experience different levels of accelerated exogenous aging, resulting in problems such as age spots, dullness, wrinkles, and sagging skin.

[0003] With the development of cosmetic technology, the quality of various skincare products varies greatly. Some cosmetics, although containing a large number of active ingredients and possessing high efficacy, have also caused allergic reactions such as erythema and swelling in many people, raising questions about their safety. Furthermore, ingredients in cosmetics currently used for anti-aging, such as vitamin C, hormones, and peptides, while showing noticeable effects in a short period, often have drawbacks such as easy accumulation, difficulty in decomposition, low safety, and poor stability, potentially causing toxicity to the human body.

[0004] Caviar is rich in growth factors essential for the skin, enabling it to quickly penetrate the skin's deeper layers, activate its regenerative capacity and cell renewal process, repair damaged skin, and exert anti-wrinkle, anti-aging, and rejuvenating effects. CN114712269A discloses an anti-aging essential oil composition, its preparation method, and its application. This composition comprises an oil phase, an emulsifier, excipients, and an aqueous phase. The oil phase includes camellia seed oil, frankincense essential oil, and sandalwood essential oil. The emulsifier is a solution of chitosan and guar gum. The aqueous phase includes water and skin conditioning agents, including salmon roe extract, peach fruit extract, and corn gluten amino acids. The composition has firming, wrinkle-reducing, and anti-aging effects and can be applied to masks, serums, toners, and creams, offering significant anti-wrinkle and anti-aging effects, safety, and a wide range of applications. However, existing strategies for using caviar extract in cosmetics are relatively few, with limited effects and high processing costs. Therefore, developing more related products is essential. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide an anti-aging essence containing caviar extract and its preparation method.

[0006] To achieve this objective, the present invention employs the following technical solution:

[0007] In a first aspect, the present invention provides an anti-aging essence containing caviar extract, wherein the anti-aging essence comprises a skin regulator containing sturgeon caviar extract and salmon roe extract.

[0008] This invention creatively develops an essence product containing sturgeon caviar extract and salmon roe extract, and discovers that these two ingredients possess excellent anti-aging effects, making them suitable for use in the preparation of various cosmetics, and are gentle and non-irritating. Furthermore, sturgeon caviar extract and salmon roe extract have a potential synergistic effect in anti-aging efficacy.

[0021] The sturgeon roe extract is obtained by enzymatic hydrolysis using a combination of papain and subtilisin, while the salmon roe extract is obtained by enzymatic hydrolysis using a combination of papain and neutral protease. This makes the products easier for the skin to absorb and utilize, thus promoting their efficacy. At the same time, the excellent distribution of the enzymatic hydrolysate can also better improve the overall anti-aging effect of the products.

[0022] Preferably, the amount of protease added is 1000-5000 U / g, such as 1000 U / g, 2000 U / g, 3000 U / g, 4000 U / g, 5000 U / g, etc. Other specific values ​​within this range can be selected, and will not be described in detail here.

[0023] Preferably, the enzymatic hydrolysis treatment in step (1) is carried out at a pH of 6-8 (e.g., pH=6, pH=7, pH=8, etc.) and a temperature of 35-45℃ (e.g., 35℃, 38℃, 40℃, 42℃, 45℃, etc.) for 3-8 hours (e.g., 3h, 4h, 5h, 6h, 7h, 8h, etc.).

[0027] Preferably, the deacidification treatment is carried out at 50-60℃ (e.g., 50℃, 52℃, 54℃, 56℃, 60℃, etc.) for 0.5-2h (e.g., 0.5h, 0.8h, 1h, 1.2h, 1.5h, 2h, etc.).

[0028] Preferably, each centrifugation is performed independently at 3000-5000 rpm (e.g., 3000 rpm, 3500 rpm, 4000 rpm, 4500 rpm, 5000 rpm, etc.) for 5-15 minutes (e.g., 5 minutes, 8 minutes, 9 minutes, 10 minutes, 12 minutes, 13 minutes, 14 minutes, 15 minutes, etc.).

[0031] The preferred combination is acetyl tetrapeptide-9 and palmitoyl tripeptide-5.

[0032] Adding palmitoyl peptides or acetyl peptides to the above-mentioned serums can significantly enhance their antioxidant and anti-aging effects. The simultaneous addition of acetyl tetrapeptide-9 and palmitoyl tripeptide-5 can maximize these effects, and they have a synergistic effect with sturgeon caviar extract and salmon roe extract in terms of antioxidant and anti-aging efficacy.

[0033] Preferably, the polyol comprises any one or a combination of at least two of glycerol, butylene glycol, propylene glycol, panthenol, erythritol, ethylhexylglycerin, or 1,2-hexanediol.

[0111] Test samples: the essence products provided in Examples 1-7 and Comparative Examples 1-3.

[0112] Test method: Place approximately 0.020-0.025g of the essence into a patch applicator. Apply the patch applicator containing the test substance to the flexor surface of the subject's forearm using non-irritating adhesive tape. Gently press with the palm of your hand to ensure even adhesion to the skin, and leave for 24 hours.

[0115] Test Example 2

[0116] DPPH scavenging ability test:

[0117] Test samples: the essence products provided in Examples 1-7 and Comparative Examples 1-3.

[0118] Test Method: DPPH free radical is a stable free radical. Utilizing the characteristic that its ethanol solution turns purple and has a characteristic absorption peak at 517 nm, the antioxidant properties of the test sample can be determined. Transfer 2 mL of DPPH-ethanol solution (0.2 mmol / L) to 2 mL of the test sample, mix thoroughly, and let stand in the dark for 30 min. Use anhydrous ethanol as a blank control. Measure the absorbance at 517 nm. Calculate the DPPH scavenging rate of the test sample using the following formula:

[0119] DPPH clearance rate (%) = [1-(A i -A j ) / A0]×100%;

[0120] In the formula, A i A represents the absorbance of the sample reacting with the DPPH reaction system. j A0 is the absorbance of the sample to be tested mixed with anhydrous ethanol, and A0 is the absorbance of the blank control anhydrous ethanol.

[0121] The ability of the serum to scavenge DPPH free radicals was tested using the method described above. The specific data are shown in Table 1.

Each group used equal amounts of the anti-aging serums provided in Examples 1-7 and Comparative Examples 1-3 after cleansing in the morning and evening. A before-and-after control was used. Skin roughness (the lower the SEr value, the rougher the skin) and skin elasticity were tested on the test sites of the subjects before product use and after 28 days of continuous product use.

[0130] The test metrics are as follows:

[0131]

[0132] The average change rate of each group after 28 days of product use was calculated, and the test results are shown in Table 2 below:
