Description

Technical Field

[0001] This invention discloses a composition, specifically a composition containing rose extract, its preparation method, and its application, belonging to the field of cosmetic technology. Background Technology

[0002] Aging is a comprehensive manifestation of declining and disordered physiological functions during the body's degenerative phase; it is an irreversible life process. As we age, our body composition gradually changes, leading to more pronounced wrinkles, age spots, and other signs of aging. While we cannot avoid endogenous aging, exogenous aging can be mitigated through conditioning and a healthy lifestyle.

[0003] Besides external factors causing aging, skin hydration is also a crucial aspect of skincare. A healthy stratum corneum typically contains 10-20% water. However, with changes in the external environment, climate, and age, the water content of the stratum corneum fluctuates. When the content falls below 10%, the skin becomes dry, and in more severe cases, cracking and peeling occur, accelerating skin aging over time. Therefore, anti-aging and moisturizing are extremely important, and anti-aging and moisturizing skincare products are increasingly favored by the market. Simultaneously, with the rise of plant-based ingredients, more and more natural and safe plants are being used in cosmetics.

[0004] CN111407678B discloses a microemulsion with moisturizing, brightening and anti-aging effects and its preparation method. Although it can achieve good moisturizing and brightening effects, the overall composition is too complex, and the patent mainly describes its use in cosmetic emulsion formulations. Its overall application scope is relatively limited and it is not conducive to application in other types of cosmetics.

[0005] CN110638738B discloses a method and application for preparing ecological nutrient solution by low-temperature bath treatment of roses. The ecological solution is prepared by extracting fresh roses. Although the invention has multiple functions, the freeze-thaw, freeze-drying, and fermentation processes used are complex in the whole process, and the specific effects on moisturizing, anti-aging and human effects have not been verified.

[0006] In conclusion, it is essential to develop a composition containing rose extract with good anti-aging and moisturizing effects. Summary of the Invention

[0007] To address the aforementioned shortcomings, the present invention aims to provide a composition containing rose extract with anti-aging and moisturizing effects. This composition has excellent anti-aging and moisturizing effects and can be applied in cosmetics to effectively remove free radicals in the human body, promote collagen synthesis, and improve rough skin. At the same time, the plant polysaccharides contained therein can also effectively replenish skin moisture and reduce skin moisture loss, resulting in good moisturizing and repairing effects, and can be widely used in the skin care field.

[0008] Therefore, the first technical solution provided by this invention is as follows:

[0009] A composition containing rose extract, mainly comprising the following components in parts by weight: 1-50 parts rose extract, 1-30 parts jasmine extract, and 1-30 parts saffron extract.

[0010] As a preferred option, it also includes 1-30 parts of Tremella polysaccharide.

[0011] As a preferred option, it also includes 1-30 parts of wolfberry fruit polysaccharide.

[0012] The plant extracts used in this invention all have good efficacy, as detailed below:

[0013] Rose extract, rich in polyphenols, anthocyanins and other components, can effectively scavenge free radicals and has antioxidant, beauty-enhancing and blood-circulating effects.

[0014] Jasmine flower extract contains abundant flavonoids, vitamins, trace elements, and other components, and has excellent effects in clearing heat and detoxifying, as well as anti-allergy.

[0015] Saffron extract contains crocin, whose main components are carotenoids, tannins, flavonoids, etc. It has the effects of promoting blood circulation, removing blood stasis, cooling blood and detoxifying, relieving depression and calming the mind.

[0016] Goji berry polysaccharides: can combat free radical peroxidation and reduce free radical peroxidation damage.

[0017] Tremella polysaccharides: have effects such as delaying aging and regulating blood sugar, and help increase skin elasticity.

[0018] In the plant extract composition of this invention, rose extract is the first active ingredient, which exerts antioxidant, skin-revitalizing, and brightening effects. Through cell activation and its rich content of phenols and vitamins, it can resist long-term damage caused by free radicals and effectively reduce wrinkle formation. Jasmine and saffron extracts are the second active ingredients, which can assist rose extract in exerting its effects. Jasmine is neutral in nature and has good anti-allergic effects, while saffron pigments have brightening and skin metabolism-promoting effects. Lycium barbarum polysaccharides and Tremella fuciformis polysaccharides are the third active ingredients, which invigorate blood circulation, moisturize, and promote skin absorption. They can work synergistically with the first and second active ingredients to enhance skincare efficacy.

[0064] Comparative Example 5

[0065] A composition containing rose extract comprises the following components: 40g of rose flower extract, 30g of jasmine flower extract, and 30g of saffron extract.

[0066] The above-mentioned rose-containing composition can be used to prepare anti-aging and moisturizing cosmetics. The anti-aging and moisturizing cosmetic is a topical skin preparation made by using the composition with anti-aging and moisturizing effects as the active ingredient, plus conventional pharmaceutical or cosmetic excipients or auxiliary ingredients. In specific use, the composition prepared according to the present invention is directly added to the cosmetic matrix; the amount added can be adjusted according to actual needs, preferably 0.5wt% to 10wt%.

[0067] To better illustrate the advantages of the present invention, the following are efficacy experiments of the anti-aging and moisturizing composition provided by the present invention:

[0068] Experiment 1: Antioxidant Efficacy Study – DPPH Free Radical Scavenging Experiment

[0069] Accurately weigh 41.67 mg of DPPH reagent and dilute to a 100 mL amber volumetric flask. Take 5 mL of this flask and dilute to a 50 mL amber volumetric flask with anhydrous ethanol to obtain the DPPH test solution (0.1 mmol / L). Transfer 1 mL of the DPPH test solution to each flask and add 0.5 mL of the extracts prepared in Examples 1-5 and Comparative Examples 1-5 at the same concentration, as shown in Table 4. After thorough mixing, allow to stand in the dark for 30 min. Using anhydrous ethanol as a blank control, measure the absorbance at 517 nm. Vitamin C is used as a control. Calculate the DPPH scavenging rate of each extract using the following formula:

[0070] DPPH clearance rate (%) = [1 - (As - Ar) / A0] × 100%

[0071] Where: As—absorbance of the reaction system of extract and DPPH; Ar—absorbance of extract-anhydrous ethanol; A0—absorbance of blank control anhydrous ethanol.

[0072] Table 1. Composition of the reaction solution

[0073] absorbance Volume of extract added (mL) DPPH test solution (mL) Anhydrous ethanol (mL) A0 0 1 0.5 Ar 0.5 0 1 As 0.5 1 0

[0074] The DPPH free radical scavenging rate reflects an antioxidant capacity to some extent; a higher scavenging rate indicates a better antioxidant level and effect. Therefore, the antioxidant effect can be determined by studying the ability of a composition to scavenge DPPH free radicals. Vitamin C is a recognized high-efficiency antioxidant in the cosmetics industry. This experiment used vitamin C as a control to compare and examine its antioxidant capacity.

[0075] Vitamin C was used as a positive control to investigate its DPPH free radical scavenging ability. The results are shown in Table 2. When the same mass concentration of the composition was added, the examples showed a scavenging rate similar to that of vitamin C, and Example 2 achieved a scavenging rate as high as 90.27%, indicating that the formulation composition possesses good DPPH free radical scavenging ability. Furthermore, the scavenging rates of Examples 1-5 were all higher than those of Comparative Examples 1-5, indicating that the antioxidant capacity of the composition containing five plant extracts is superior to that of the composition lacking any one of the plant extracts. The five plants have a synergistic effect, and the formulation is well-matched, indicating that the composition has good antioxidant capacity.

[0078] Experiment 2: Antioxidant Capacity Study – ABTS Free Radical Scavenging Experiment

[0079] The compositions prepared in Experimental Examples 1-5 and Comparative Examples 1-5 were tested. The tests are as follows:

[0080] (1) Preparation of ABTS+ standard stock solution:

[0081] Accurately weigh 0.0384 g of ABTS+, dissolve it in distilled water, and dilute to a volumetric flask with distilled water to obtain an ABTS+ concentration of 7 mmol·L⁻¹. -1 Accurately weigh 0.0066 g of K₂S₂O₈ (potassium persulfate), dissolve it in distilled water, and dilute to a volumetric flask with distilled water to obtain a K₂S₂O₈ concentration of 2.45 mmol·L⁻¹. -1 Then, mix the two solutions in a brown bottle (1:1 ratio) and leave it in the dark at room temperature overnight (12-16 hours) to obtain an ABTS+ solution.

[0082] ABTS+ solution was diluted with phosphate buffer (10 mmol·L⁻¹). -1 Dilute the solution (pH 7.4) by approximately 25 times until its absorbance at 734 nm wavelength and 30 °C is 0.700 ± 0.020, thus obtaining the ABTS+ working solution.

[0083] (2) Sample clearance rate test

[0084] Take 1 mL of the sample solution diluted appropriately into each test tube, add 3 mL of ABTS+ working solution, mix thoroughly, and store at room temperature in the dark for 10 min. Measure the absorbance at 734 nm, using anhydrous ethanol as a blank control. Vitamin C was also used as a control. Calculate the ABTS free radical scavenging rate of each extract at different concentrations using the following formula, and calculate the IC50 value (based on solid content) using SPSS software. The ABTS free radical scavenging rate is calculated using the following formula:

[0085] ABTS radical scavenging rate (%) = [1 - (Ai - Aj) / Ac] × 100%

[0086] In the formula: Ai is 1 mL of sample solution + 3 mL of ABTS + The absorbance value of the solution mixture; Aj is the absorbance value of the mixture of 1 mL sample solution + 3 mL anhydrous ethanol; Ac is the absorbance value of the mixture of 1 mL anhydrous ethanol + 3 mL ABTS. + The absorbance value of the solution mixture.

[0087] Table 3. Experimental Results of the Composition's Ability to Scaveng ABTS Free Radicals

[0088] Sample Name ABTS half-inhibitory concentration IC50 (μg / mL) Vitamin C 1.56 Example 1 4.57 Example 2 3.64 Example 3 4.25 Example 4 6.56 Example 5 8.82 Comparative Example 1 12.89 Comparative Example 2 20.85 Comparative Example 3 15.63 Comparative Example 4 10.63 Comparative Example 5 13.52

[0089] Table 3 shows that the half-maximal inhibitory concentration (IC50) of vitamin C (dry weight) for ABTS free radical scavenging was 1.56 μg / mL, while that of Example 2 was 3.64 μg / mL. The IC50 of Example 2 was slightly higher than that of vitamin C, but within the same order of magnitude, indicating that the composition possesses good ABTS scavenging ability. Furthermore, the table shows that the IC50 values ​​of Examples 1-5 were lower than those of Comparative Examples 1-5, indicating that the antioxidant capacity of the composition containing all five plant extracts was superior to that of the composition lacking any one of the plant extracts. This further demonstrates the rationality of the formulation, showing a synergistic effect and jointly exerting its excellent antioxidant effect.

[0090] Experiment 3: Human Efficacy Test

[0091] To further evaluate the skincare effects of the rose composition on humans, this experiment preferred Example 2 was added to the formulation matrix emulsion at a dosage of 5%. The formulation matrix is ​​as follows: 1.5 parts C14-22 alcohol / C12-20 alkyl glucoside / water / glucose, 1 part cetearyl glucoside / sorbitan olive oil ester, 2 parts cetearyl alcohol, 3 parts caprylic / capric triglyceride, 2 parts squalane, 2 parts polydimethylsiloxane, 5 parts glycerin, 3 parts butylene glycol, 0.05 parts xanthan gum, 0.2 parts carbomer, 0.2 parts arginine, appropriate amount of preservative, and water to 100 parts. The formulation matrix emulsion was set up as a blank control to test the anti-aging and moisturizing effects of the sample.

[0092] Experimental methods

[0093] The anti-aging moisturizing lotion prepared above was used on 30 randomly selected healthy Chinese subjects. The test environment required a temperature of 20℃-22℃ and a humidity of 40%-60%. The test population consisted of 30 healthy volunteers aged 35-50 years (mean 42 years) with noticeable wrinkles, dull and rough skin. These volunteers had no allergies to cosmetics, no acute facial inflammation, had not used hormonal drugs or immunosuppressants, had not participated in other clinical trials, and had not applied any topical preparations. They were randomly divided into two groups of 15 each, using the anti-aging moisturizing cream and the cream base, respectively.

[0094] After cleansing their faces with warm water, volunteers in each group applied the corresponding product evenly to their cheeks and around their eyes (in the same area) once in the morning and once in the evening for four consecutive weeks. On days 0, 14, and 28, the water content (%) in the stratum corneum of their facial skin was measured using a Corneometer CM825, skin firmness parameters were measured using a Cutometer probe, and wrinkle parameters were compared and analyzed using an Antera 3D facial image analyzer.

[0095] Statistical methods: SPSS was used for statistical analysis. The Shapiro-Wilk Test was employed to test the significance of the normal distribution of the improved values. A two-tailed score (Sig.) > 0.01 indicated a normal distribution, and a paired t-test was performed. A two-tailed score (Sig.) < 0.01 indicated a non-normal distribution, and a Wilcoxon test was performed. "ns" indicates no statistical difference (P > 0.05); "*" indicates a significant difference (0.01 ≤ P < 0.05, marked with "*"); 0.001 ≤ P < 0.01, marked with "**"; p < 0.001, marked with "***". The rate of change (percentage) = (mean after use - mean before use) / mean before use. Gray represents the cream base, and black represents the anti-aging moisturizing cream. Test results are shown below. Figure 1 , Figure 2 and Figure 3 As shown.

[0096] like Figure 1 , Figure 2 and Figure 3 As shown, after using a base emulsion containing 5% of the rose composition from Example 2, the skin stratum corneum moisture content of 15 volunteers increased by 21.38% and 31.46% on days 14 and 28, respectively, significantly higher than the 8.74% and 10.79% increases in the blank base emulsion, indicating that the composition has good moisturizing effects. Simultaneously, after 28 days of observation, the skin firmness F4 value of the anti-aging moisturizing emulsion subjects decreased by 13.91% and 23.34% on days 14 and 28, respectively, and the average skin wrinkle length decreased by 20.93% and 23.93% on days 14 and 28, respectively, with effects far superior to the blank base group. This indicates that the composition can effectively improve skin laxity, combat wrinkles, and has good firming and anti-wrinkle effects, demonstrating good anti-aging efficacy. (Note: A lower skin firmness F4 indicates firmer skin.)

[0097] In summary, this invention scientifically combines rose, jasmine, saffron, and wolfberry, and purifies them by extracting the active ingredients and using column chromatography to obtain a composition containing rose extract. This composition has good effects in scavenging free radicals, firming and anti-wrinkle, and moisturizing. It can effectively alleviate obvious wrinkles, loose skin, dryness, etc., and deeply improve the skin condition.
