Description

Technical Field

[0001] This invention relates to the field of daily chemical products technology, and in particular to a peony abrasive particle composition, its preparation method and application. Background Technology

[0002] As the largest organ in the human body, the skin's stratum corneum forms the first line of defense against external stimuli. The stratum corneum is formed from basal cells through differentiation and migration, with a normal metabolic cycle of about 28 days. However, when affected by external environmental factors, inferior cosmetics, or irregular sleep patterns, the stratum corneum's metabolic rate often slows down, preventing the natural shedding of dead skin cells. This results in a thick buildup on the skin's surface, leading to two major problems: First, the thickened stratum corneum causes the skin to appear dry, rough, and dull; second, excessively thick aging stratum corneum severely hinders the transdermal absorption of active ingredients such as moisturizers, soothing agents, whitening agents, and anti-wrinkle agents, significantly reducing the effectiveness of functional skincare products.

[0003] Currently, exfoliating products on the market are mainly divided into chemical exfoliants (using acids) and physical exfoliants (using scrubs). Physical exfoliants such as scrubs, exfoliating cleansers, and exfoliating body washes, as deep-cleansing products, work by using uniformly fine particles to generate mechanical friction during massage. This removes accumulated dead skin cells, clears deep-seated dirt from hair follicles, and unclogs skin's metabolic pathways. This physical cleansing method not only addresses skin imbalances caused by abnormal barrier function but also provides crucial pre-treatment support for the effectiveness of subsequent cosmetic products.

[0004] Despite the current abundance of exfoliating products on the market, significant limitations remain: coarse particles, potential irritation, excessive friction, limited efficacy, and complex manufacturing processes. Therefore, providing an exfoliating particle product that offers multiple benefits such as exfoliation, oil control, moisturizing, anti-oxidation, and whitening, while also being easy to prepare, is a pressing issue that needs to be addressed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a peony exfoliating particle composition with antioxidant, moisturizing, instant soothing and brightening effects, as well as its preparation method and application.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides a peony abrasive particle composition comprising the following components in parts by weight: 2-10 parts of peony seed meal powder, 10-60 parts of peony root extract and 30-80 parts of peony fermentation liquid; wherein the particle size of the peony seed meal powder is 20-100 mesh.

[0007] This invention obtains a peony exfoliating particle composition with antioxidant, moisturizing, instant soothing and brightening effects by selecting specific components and combining them.

[0008] Peony seed meal powder is the residue after extracting peony seed oil from peony seed kernels using supercritical carbon dioxide. It is rich in various functional components, including 4-8% peony seed oil, 20-30% protein, and significant amounts of peony saponins, saponins, and polysaccharides. When used in exfoliating products, particle size control of peony seed meal powder is crucial; 20-100 mesh is a suitable range, with 30-80 mesh being the preferred size. Powder particles within this range are uniform and fine, gently and effectively removing dead skin cells while avoiding skin damage from excessively large particles. In terms of ingredients and efficacy, peony saponins and saponins work synergistically to cleanse, not only penetrating deep into pores to dissolve dirt, but also possessing antihistamine activity, effectively soothing skin sensitivity and reducing discomfort during the exfoliation process; the amino acids rich in proteins, as important raw materials for skin cell renewal, can accelerate the repair and regeneration of epidermal cells after the removal of aged keratinocytes, restoring the skin to a smooth and delicate state; unsaturated fatty acids act as natural moisturizers, quickly replenishing the skin with moisture and nutrients after exfoliation, and forming a protective film on the skin surface to effectively lock in moisture and prevent dryness and tightness caused by physical friction.

[0009] Peony root extract is rich in paeonol and its derivatives, which can inhibit pathogenic bacteria such as Staphylococcus aureus. It exerts its antibacterial effect by disrupting cell membranes and interfering with metabolism. It can also inhibit the release of inflammatory factors such as IL-6 and TNF-α, thus improving skin inflammation and infections. Its phenolic hydroxyl structure has strong antioxidant properties, which can scavenge free radicals, block oxidative stress, and delay cell aging.

[0010] Peony fermentation stock solution is the filtrate obtained by processing peony leaves through a lactic acid bacteria fermentation process. During fermentation, enzymes secreted by microorganisms (such as lactic acid bacteria and yeast) can decompose polysaccharides, proteins, and macromolecular glycosides in peony into smaller molecules. Small molecule phenols and short-chain fatty acids in the fermentation filtrate can directly penetrate the skin through hair follicles and the stratum corneum, while the large molecular components in traditional extracts have lower penetration efficiency. This invention's peony fermentation stock solution is prepared according to the preparation method of peony fermentation stock solution described in published patent CN114209624A (202111600527.4). The specific preparation method of peony fermentation stock solution is as follows: (1) Grind the dried peony plant into powder and sieve it to obtain powdered peony; (2) Mix powdered peony with water, sterilize, and cool to room temperature to obtain a mixture; (3) Inoculate the mixture with lactic acid bacteria for fermentation culture.

[0042] Test Example 1 The antioxidant properties of the abrasive particle compositions of Examples 1-5 and Comparative Examples 1-5 were tested.

[0043] Blank control group: 24 two-day-old zebrafish embryos were randomly selected and placed into a 96-well plate, with one embryo and 0.2 mL of zebrafish embryo culture medium in each well.

[0044] Experimental group: 24 two-day-old zebrafish embryos were randomly selected and placed into 96-well plates. Each well contained one fish embryo and 0.2 mL of sample culture medium. The sample culture medium was a zebrafish embryo culture medium containing 5 g / L of a frosted particle composition.

[0045] Fish embryos from each group were cultured in a 28℃±1℃ incubator for 24h±1h. They were then transferred to 24-well plates, with each well containing 12 fish embryos and 2mL of reactive oxygen species (ROS) test solution, and placed in a 28℃±1℃ incubator for another 2h±0.2h. H2DCFDA staining was performed using a cell reactive oxygen species analysis kit (H2DCFDA). The fish embryos were placed sideways and photographed under a fluorescence stereomicroscope using standardized parameters. ROS signal intensity was measured, and ROS clearance rate was calculated.

[0046] The ROS inhibition rate results of the examples and comparative abrasive particle compositions are shown in Table 3 below. Table 3 Table 3 shows that the ROS inhibition rate of the peony abrasive particle composition in the examples was 46%~64%, and its antioxidant activity was significantly higher than that of the comparative example.

[0047] As can be seen from Example 1 and Comparative Examples 1 and 2, the peony root extract and peony flower fermentation liquid in the peony abrasive particle composition of the present invention have a synergistic effect; at the same time, neither the peony root extract nor the peony fermentation liquid can be omitted.

[0048] As can be seen from Example 1 and Comparative Examples 3 and 4, the particle size of peony seed meal powder in the peony abrasive particle composition of the present invention needs to meet a specific range. If it is too high or too low, it will lead to a decrease in the antioxidant properties of the composition.

[0049] As can be seen from Example 1 and Comparative Example 5, the peony exfoliating particle composition of the present invention has better antioxidant properties than the commonly used exfoliating particle walnut powder on the market.

[0050] Test Example 2 The moisturizing properties of the abrasive particle compositions of Examples 1-5 and Comparative Examples 1-5 were tested.

[0051] The testing method is as follows: Blank control group: 24 fish embryos were randomly selected and placed into a 3cm culture dish, and 5mL of zebrafish embryo culture medium was added; Sample group: 24 fish embryos were randomly selected from each group and placed into a 3cm culture dish. 5mL of dehydration model inducing agent solution containing 0.1g / L of sample was added. Model group: 24 fish embryos were randomly selected and placed in a 3cm culture dish, and 5mL of dehydration model induction agent solution was added; The culture conditions were as follows: fish embryos were cultured in a constant temperature incubator at 28℃±1℃ for 96 h. After 96 h of culture, the fish embryos were photographed under a microscope to measure the tail area and perform statistical analysis. The changes in tail area of ​​the fish embryos in the experimental group / positive control group and the blank control group were compared, and the tail area shrinkage inhibition rate was calculated to evaluate the 96-hour moisturizing efficacy of the product.

[0052] The moisturizing rate is the inhibition rate of tail area reduction in zebrafish embryos. The inhibition rate is calculated as [(SM) / (BM)] × 100, where: S is the average tail area of ​​the embryos in the test group; B is the average tail area of ​​the embryos in the blank control group; and M is the average tail area of ​​the embryos in the model control group. The inhibition rate is the moisturizing rate.

[0053] The 96-hour moisturizing rate results of the examples and comparative abrasive particle compositions are shown in Table 4 below. Table 4 Table 4 shows that the peony exfoliating particle composition of the examples has a moisturizing rate of 32%~42%, indicating a certain moisturizing effect.

[0054] As can be seen from Example 1 and Comparative Examples 1 and 2, the peony root extract and peony flower fermentation liquid in the peony abrasive particle composition of the present invention have a synergistic effect; at the same time, neither the peony root extract nor the peony fermentation liquid can be omitted.

[0055] As can be seen from Example 1 and Comparative Examples 3 and 4, the particle size of peony seed meal powder in the peony abrasive particle composition of the present invention needs to meet a specific range. If it is too high or too low, the moisturizing effect of the composition will be reduced.

[0056] As can be seen from Example 1 and Comparative Example 5, the peony exfoliating particle composition of the present invention has a better moisturizing effect than the commonly used exfoliating particle walnut powder on the market.

[0057] Test Example 3 Using the exfoliating scrub as an example, we tested its exfoliating, immediate soothing, and brightening effects.

[0058] We recruited 120 female subjects aged 25-45 with sensitive skin and randomly divided them into 12 groups for the experiment.

[0059] After cleansing their faces, subjects left their faces still for 30 minutes. Initial transepidermal water loss (TEWL), ITA° (characterizing skin brightness), and skin texture were measured in the facial area using CK electronic and VISIA+Image ProPlus image analysis software. After applying a scrub product, the subjects left it on for 15 minutes, then rinsed it off. TEWL, ITA°, and skin smoothness were measured again after 30 minutes. Key indicators were calculated. TEWL Improvement Rate (%) = [(Initial a value - Post-use a value) / Initial a value] × 100%, Skin ITA° value improvement rate (%) = [(ITA° value after use - initial ITA° value) / initial ITA° value] × 100%, Smoothness improvement rate = [(initial texture value - texture value after use) / initial texture value] × 100%.

[0060] The exfoliating, soothing, and brightening effects of the scrubs used in Examples 1-7 and Comparative Examples 1-4 are shown in Table 5 below. Table 5 The results in Table 5 show that the scrub of the present invention has exfoliating, immediate soothing and brightening effects.

[0061] The TEWL improvement rate, ITA° value improvement rate, and smoothness improvement rate of the comparative scrub were all lower than those of the scrub in Example 1, indicating that the scrub prepared with the peony exfoliating particle composition of the present invention has better effects. The ITA improvement rate of the scrub of the present invention is positive. The ITA change value represents the keratinocyte renewal rate, indicating that the scrub of the present invention also has a whitening effect.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
