Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and particularly relates to a firming and anti-wrinkle composition containing hydroxy-pinacolone 9-cis-retinoate and a preparation method thereof. Background Art

[0002] With the increasing demand for beauty and personal care products, the market demand for cosmetics and skin care products with firming and anti-wrinkle effects is also rising continuously. Traditional firming and anti-wrinkle products mostly rely on the supplement of collagen, the increase of moisturizing ingredients, or some physical means to improve skin firmness. However, these methods often have limited effects, and long-term use may have side effects or unstable effects.

[0003] In recent years, scientific research has found that some specific active ingredients have significant effects in improving skin aging signs, especially reducing wrinkles and enhancing skin firmness. Among them, it is recorded in CN119139160A that hydroxy-pinacolone 9-cis-retinoate has become an emerging ingredient in anti-wrinkle products due to its low irritation and good stability. It can promote skin cell renewal and enhance collagen synthesis, thus effectively improving skin laxity and wrinkle problems.

[0004] However, the use of a single ingredient often fails to achieve the ideal anti-wrinkle effect, and long-term dependence on a certain ingredient may also lead to reduced skin adaptability. Therefore, it is particularly important to develop a firming and anti-wrinkle composition with multi-component compounding and synergistic effects.

[0005] As a bioactive substance, polydeoxyribonucleotide has been found in recent years to have the effects of promoting skin cell regeneration and repairing damaged skin tissues. It can enhance the self-repair ability of the skin, thereby counteracting skin aging, while the extract of Cornus officinalis fruit is rich in various antioxidant components, which can scavenge free radicals, protect the skin from damage by the external environment, and at the same time has certain moisturizing and nourishing effects. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a firming and anti-wrinkle composition containing hydroxy-pinacolone 9-cis-retinoate.

[0038] In the present invention:

[0039] Hydroxypinacolone retinoate can resist fine lines and wrinkles, while promoting the production of collagen and elastin, improving the elasticity and firmness of the skin, making the skin smoother and more delicate. At the same time, it also has the effect of inhibiting tyrosinase, reducing pigment deposition, enhancing the gloss and firmness of the skin, making the skin color brighter. In addition, it has antioxidant properties, which can reduce the damage of free radicals to the skin, lower the skin roughness, and inhibit sebum secretion, making the skin more refreshing.

[0040] Polydeoxyribonucleotide can stimulate the activity of adenosine A2A receptor, affect transcription factors, and secrete growth factors such as epidermal growth factor (EGF) and fibroblast growth factor (FGF), thereby stimulating the growth of epidermal cells, increasing the synthesis of collagen, and promoting the repair and regeneration of damaged skin. At the same time, it has good anti-inflammatory properties and can reduce skin inflammatory reactions by inhibiting the expression of inflammatory cytokines.

[0041] The cornel fruit extract provided by the present invention is rich in morroniside, has excellent antioxidant performance, can effectively scavenge free radicals, resist oxidative stress reaction, delay skin aging, reduce wrinkles and relaxation. At the same time, it can inhibit the activity of inflammatory factors and alleviate skin redness and allergy.

[0081] The antioxidant activities of the samples to be tested were evaluated using the DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging method. This method is based on the principle of color change after the reaction between DPPH free radicals and antioxidants, and the antioxidant activity is quantified by measuring the change in absorbance.

[0082] DPPH solution: Dissolve 1 mg of DPPH in 24 mL of absolute ethanol to prepare a 0.1 mmol / L DPPH solution, sonicate for 5 min, and shake well to mix evenly.

[0083] Sample group to be tested: The samples to be tested were respectively prepared into sample solutions with a concentration of 50 wt% using absolute ethanol. Take 2 mL of the sample solution to be tested and 2 mL of the DPPH solution and add them to the same test tube, shake well, and let it stand in the dark at room temperature for 30 min, then measure the absorbance value at 520 nm, denoted as A 待测样品 ;

[0084] Control group: At the same time, measure the absorbance value after mixing 2 mL of the DPPH solution and 2 mL of absolute ethanol, denoted as A 对照 ;

[0085] Background group: The absorbance value measured after replacing the DPPH solution in the sample group to be tested with an equal volume of absolute ethanol is denoted as A 10 ; The absorbance value measured after replacing the DPPH solution in the control group with an equal volume of absolute ethanol is denoted as A 20 .

[0086] Calculate the scavenging ability of different samples to be tested for DPPH free radicals according to the following formula, and the results are shown in Table 4.

[0087] DPPH free radical scavenging rate = [1 - (A 待测样品 - A 10 ) / (A 对照 - A 20 )] × 100%

[0088] Elastase inhibition assay

[0089] Samples to be tested: The essence milks prepared in Examples 1-4 and Comparative Examples 1-5.

[0091] Grouping was set according to the instructions of the kit:

[0092] Samples to be tested group: Add 50 μL of the sample solution to be tested with a concentration of 50 wt% prepared with the buffer in the kit to a black 96-well bottom transparent plate, then add 100 μL of elastase working solution at 0.2 U / mL. After shaking and reacting at room temperature for 15 min, add 50 μL of elastase fluorescence conjugate at 100 μg / mL to each well. After incubating in the dark at room temperature for 30 min, measure the fluorescence intensity at an excitation wavelength of 485 nm and an emission wavelength of 530 nm with a fluorescence microplate reader, denoted as MFI 待测样品 ;

[0093] Control group: Replace the sample solution to be tested with an equal volume of 50 μL of buffer, and keep the rest unchanged. The measured fluorescence intensity is denoted as MFI 对照 ;

[0094] Background group: Replace the sample solution to be tested with 50 μL of buffer, and replace the elastase working solution with 100 μL of buffer, and keep the rest unchanged. The measured fluorescence intensity is denoted as MFI 背景 .

[0095] Calculate the inhibitory ability of different samples to be tested on elastase according to the following formula, and the results are shown in Table 4.

[0096] Elastase inhibition rate = [1 - (MFI 待测样品 - MFI 背景 ) / (MFI 对照 - MFI 背景 )] × 100%
