Description

Technical Field

[0001] The present invention relates to the technical field of skin care products, and particularly relates to a facial care and skin nourishing firming oil and its production process. Background Art

[0002] Some existing facial care and skin nourishing firming oils contain harmful ingredients such as heavy metals: they may contain heavy metals such as mercury and lead. Long-term use of such products will cause heavy metals to gradually accumulate in the body, damage organs such as the nervous system and kidneys of the human body, and may also affect the hematopoietic function and cause problems such as anemia. For example, some facial care and skin nourishing firming oils produced by irregular manufacturers, in order to pursue quick effects, illegally add heavy metal components, which will pose a potential threat to health after use. In terms of effects: the effects are not lasting: although the firming oil may make the skin feel firm in a short time after use, this effect is often temporary and it is difficult to fundamentally solve problems such as skin relaxation. As time goes by, the skin may gradually return to its original state and cannot achieve long-term firming effects. Summary of the Invention

[0039] Preferably, the preparation steps of the gelatin / cellulose nanowhisker composite are as follows: Dispersing the cellulose powder raw material in an ethanol solvent, treating the cellulose suspension with a high-pressure homogenizer, with a pressure range of 100 - 200 MPa, a homogenization temperature of 30 - 40 °C, a circulation number of 5 - 10 times, and a mass concentration range of the cellulose suspension of 0.8% - 2.2%. During the homogenization process, continuously stir the cellulose suspension at a stirring speed of 150 - 200 rpm. After the treatment, a cellulose nanowhisker suspension is obtained. Then, add gelatin accounting for 0.5% - 1.6% of the mass of the cellulose nanowhisker suspension, continue to stir for 2 - 3 minutes, and then filter and dry to obtain the gelatin / cellulose nanowhisker composite.

[0040] Preferably, the cellulose suspension is treated with a high-pressure homogenizer, with a pressure range of 150 - 180 MPa, a homogenization temperature of 34 - 38 °C, a circulation number of 6 - 8 times, and a mass concentration range of the cellulose suspension of 1% - 1.8%.

[0045] A production process of a skin care and firming oil includes the following steps:

[0046] At room temperature, component A is sequentially added to the stirring pot, with a stirring speed of 20 - 30 r / min, stirred for 10 - 20 minutes, then component B raw materials and component C raw materials are sequentially added, with a stirring speed of 20 - 30 r / min, stirred for 15 - 25 minutes, and after passing the inspection against the control sample, it is discharged.

[0047] Preferably, at room temperature, component A is sequentially added to the stirring pot, with a stirring speed of 25 r / min, stirred for 15 minutes, then component B raw materials and component C raw materials are sequentially added, with a stirring speed of 25 r / min, stirred for 20 minutes, and after passing the inspection against the control sample, it is discharged.

[0048] Advantages of the present invention: This firming oil does not contain harmful ingredients such as heavy metals and will not pose a potential threat to health after use. The effect is long-lasting, fundamentally solving problems such as skin relaxation and gradually achieving a long-term firming effect.

[0049] The gelatin / cellulose nanowhisker complex increases stability. Gelatin can keep the components in the firming oil stable, preventing precipitation and separation. The cellulose nanowhiskers are small in size and have a very large specific surface area. The combination of the two can significantly increase the viscosity and texture of the firming oil. In the gelatin / cellulose nanowhisker complex, the proteoglycan component in gelatin has an antioxidant effect and can prevent damage by free radicals. The cellulose nanowhiskers are elastic and durable and are also effective antioxidants, which can be used to combat skin aging. The gelatin / cellulose nanowhisker complex has excellent moisture absorption capacity, which may help bring the functional nutrients in the firming oil into the skin, promoting the absorption of these substances by the skin and enhancing the firming effect. The gelatin / cellulose nanowhisker complex exists in the firming oil in a suspended form. After treatment, these complexes are processed to be small enough and stably dispersed, invisible to the naked eye, and it is difficult to detect the granular feeling during use.

[0125] (1) Microbiological inspection: The detection results of the total number of colonies, the total number of molds and yeasts, thermotolerant coliforms, Staphylococcus aureus, and Pseudomonas aeruginosa all meet the requirements of the "Cosmetics Safety and Technical Specifications" (2015 edition).

[0126] (2) Physicochemical inspection: The detection results of mercury, lead, arsenic, and cadmium all meet the requirements of the "Cosmetics Safety and Technical Specifications" (2015 edition).

[0127]

[0128]

[0129] <Compound efficacy test>

[0130] The gelatin and cellulose nanowhiskers were directly mixed and then replaced the gelatin / cellulose nanowhisker compound and added to the formulation of Example 3 to make the direct mixing group. The Example 3 containing the gelatin / cellulose nanowhisker compound was used as the compound group. The compound efficacy test was carried out by comparing the two groups. The direct mixing group and the compound group were respectively shaken well, filled into 10 mL standard glass centrifuge tubes, and filled to 80%-90% of the tube volume.

[0131] Record the initial volume

[0132] Centrifugation conditions Rotation speed: 3000 rpm

[0133] Time: 10 min, 15 min, 30 min

[0134] Temperature: 25 ± 1 °C

[0135] Observation and measurement after centrifugation

[0136] Take out the centrifuge tube and let it stand vertically for 5 minutes

[0137] Record the stratified volume

[0138] Calculation of stratification rate:

[0139] Stratification rate (%) = (stratified volume / initial volume) × 100%

[0140]

[0141] Thus, it can be seen that the treated gelatin / cellulose nanowhisker compound has the effect of improving the stability of the formulation.

[0142] <Anti-wrinkle and firming efficacy test of cosmetics>

[0143] 1. Test principle

[0144] Elastase is mainly synthesized and secreted by fibroblasts. It is a proteolytic enzyme with extremely high selectivity and specificity. It has a catalytic hydrolysis effect on many amino acids such as glycine, leucine, alanine, valine, etc. containing carboxyl polypeptide bonds, and can decompose elastin in connective tissue proteins, resulting in skin aging.

[0145] The principle of the elastase inhibition experiment is that elastase reacts with the enzyme substrate, and the absorbance changes after adding the active substance. The size of the change in absorbance can reflect the size of the inhibition rate of the elastase inhibitor.

[0146] This test method is an in vitro method, which mainly characterizes the anti-wrinkle and firming efficacy by evaluating the inhibition rate of the test sample on elastase activity. It is applicable to evaluate cosmetics that achieve anti-wrinkle and firming effects by inhibiting elastase.

[0147] 2. Test method

[0148] 2.1. Add appropriate buffer solution, solutions of samples at different concentrations (sample solution of Example 3) or control solution, and substrate into a 96-well plate. After shaking and mixing evenly, incubate for 20 minutes. Then add elastase solution, immediately shake and incubate for 10 minutes. Measure the absorbance at 410 nm with an enzyme-labeling instrument, and analyze and process the data to calculate the inhibition rate of the test sample on elastase.

[0149] The standard adopted in this detection is: QTC-C-LAB-TOP-056 "In Vitro Test Method for Anti-Wrinkle and Firming Efficacy of Cosmetics (Elastase Inhibition Method)". In the negative control group in the detection standard: it only contains buffer solution and enzyme / substrate, which is used to exclude non-specific interference. The test sample group: contains the cosmetic sample solution, which is used to evaluate its inhibition effect. The positive control group: uses a substance with a known high inhibition rate (such as quercetin solution) to verify the sensitivity and reliability of the experimental system.

[0150] 2.2. Result calculation

[0151] Elastase inhibition rate (%) = [1 - (A - B) / (C - D)] x 100%

[0152] In the formula: A is the absorbance of the experimental group (containing substrate, buffer solution, elastase solution, sample solution (sample group) / quercetin solution (positive control group) / water (negative control group))

[0153] B is the absorbance of the experimental blank group (containing substrate, buffer solution, without elastase solution, sample solution (sample group) / quercetin solution (positive control group) / water (negative control group))

[0154] C is the absorbance of the control group (containing substrate, buffer solution, elastase solution, without sample solution)

[0155] D is the absorbance of the blank group (containing substrate, buffer solution, without elastase solution, without sample solution).

[0156] 3. Test results

[0157]

[0158] For the analysis of the difference in elastase inhibition rate, see Figure 1 .

[0159] Note: When using statistical analysis software for analysis, compared with the negative control group, a p value < 0.05 in the positive control group and the test sample group indicates statistical significance, denoted by "*"; p ≥ 0.05 indicates no statistical significance.

[0160] 4. Conclusion

[0161] According to the test results:

[0162] 4.1. When the concentration of the positive control group is 200 μg / mL, the elastase inhibition rate ≥ 90%, indicating that the reaction system is effective;

[0163] 4.2. When the concentration of the test sample group is 1.67% (v / v), the elastase inhibition rate is approximately 17.28%, showing statistical significance compared with the negative control group (p < 0.05). This indicates that the test sample has the ability to inhibit elastase activity at this tested concentration and can be used as one of the evidence supports for the claim that the sample has a firming effect.
