Description

Technical Field

[0001] The invention belongs to the field of daily cosmetic preparations, and particularly relates to a refreshing oil-controlling composition and a preparation method and application thereof. Background Art

[0002] In the pursuit of nature, health and environmental protection in modern life, consumers have higher requirements for the source of ingredients and efficacy of personal care products. Although traditional rinse-off products, especially those containing chemical synthetic surfactants, perform well in cleaning effects, long-term use may damage the skin barrier, leading to skin sensitivity, dryness and other problems. In addition, with the intensification of environmental pollution and the acceleration of people's pace of life, problems such as excessive skin oil secretion and clogged pores are becoming increasingly prominent, and consumers are increasingly demanding rinse-off products with oil control and refreshing effects.

[0003] In response to this market demand, plant-based surfactants have gradually attracted attention due to their natural, mild and biodegradable properties. Plant-based surfactants are derived from natural plants, such as coconut oil, palm oil, soybean oil, etc., and are transformed through specific chemical or biological processes. They not only have good cleaning ability, but also reduce irritation to the skin, while giving the product more natural ingredients and skin care effects.

[0004] However, the oil control effect of plant-based surfactant rinse products on the market is often unsatisfactory. Although some products add plant extracts or essential oils to improve the oil control effect, due to unreasonable formula design or insufficient activity of plant ingredients, the oil control effect is limited and cannot meet consumers' expectations.

[0005] Therefore, developing a rinse-off product that has both the mildness and environmental friendliness of plant-based surfactants and significant oil control effects has become an important demand in the current market. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a composition with refreshing oil-control effect containing a plant-based surfactant, an amino acid surfactant, and a plant extract composition, as well as a preparation method and application thereof. The composition is achieved by carefully screening and compounding plant-based surfactants, combined with specific plant extract ingredients and moisturizing ingredients with oil-control effects, to achieve multiple functions of gentle cleansing, dense and multi-foaming, effective oil control and lasting moisturizing, and meet consumers' demand for natural, healthy and efficient cleaning products and other rinse-off products.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] In a first aspect, the present invention provides a refreshing oil-control composition, comprising the following components by mass percentage:

[0009] Skin conditioning components 1-2%;

[0011] Sodium cocoamidopropionate 2-15%;

[0012] Disodium lauroyl glutamate 2-15%;

[0013] Lauramidopropyl betaine 2-4%;

[0014] The skin conditioning component consists of Hypericum perforatum flower / leaf / stem extract, Capparis spinosa fruit extract and Sanguisorba officinalis root extract.

[0015] Preferably, the mass ratio of the Capparis spinosa fruit extract, the Hypericum perforatum flower / leaf / stem extract and the Sanguisorba officinalis root extract in the skin conditioning component is (4.1-4.5):(0.5-0.7):0.1.

[0016] Further preferably, the method for preparing the caper fruit extract comprises the following steps:

[0017] S1. Take dried caper fruit and crush it through a sieve of ≥100 mesh to obtain caper fruit powder;

[0018] S2. Adding an ethanol aqueous solution with a concentration of ≥ 80 wt % to the caper fruit powder, soaking and refluxing for extraction at 80-90° C. for 3 times, each time for 1 h, combining the obtained filtrates, concentrating the filtrates under reduced pressure, and drying to obtain a caper fruit extract.

[0019] Preferably, the composition further comprises a solvent, and the solvent is water.

[0020] More preferably, the water is deionized water.

[0021] In a second aspect, the present invention provides the use of the refreshing oil-controlling composition described in the first aspect in the preparation of a rinse-off type washing and care preparation having refreshing, oil-controlling, oil-removing, cleansing, anti-inflammatory, acne-removing and / or moisturizing effects.

[0022] In a third aspect, the present invention provides a refreshing oil-controlling cleansing product, comprising the refreshing oil-controlling composition described in the first aspect.

[0023] Furthermore, the cleaning product also includes a moisturizer, a preservative, a cationic conditioner, and a pH adjuster.

[0024] Furthermore, the moisturizing agent is at least one of glycerin, allantoin, panthenol, butylene glycol, and 1,2-hexanediol;

[0025] The preservative is at least one of p-hydroxyacetophenone and phenoxyethanol;

[0026] The cationic conditioning agent is polyquaternium-39;

[0027] The pH adjuster is citric acid.

[0028] In a fourth aspect, the present invention provides a method for preparing the refreshing oil-controlling cleansing product according to the third aspect, comprising the following preparation steps:

[0029] (1) Add the pH adjuster into deionized water and stir to dissolve completely at room temperature to obtain phase A;

[0030] (2) adding butylene glycol, 1,2-hexanediol, p-hydroxyacetophenone, phenoxyethanol and panthenol into deionized water, heating to 55-60° C., stirring and dissolving uniformly to obtain phase B;

[0031] (3) Add deionized water to the reaction container, and add sodium palm oleate, sodium cocoylaminopropionate, disodium lauroyl glutamate, lauroyl amide propyl betaine, allantoin and glycerin in sequence, heat to 83±2°C and keep warm, stir until dissolved evenly, open condensation water, stir and cool to 43±2°C, which is phase C;

[0032] (4) Add phase B, skin conditioning components and polyquaternium-39 to phase C, stir and dissolve evenly, then add phase A to adjust the pH to prepare a refreshing oil-control cleansing product.

[0033] In the present invention:

[0034] Sodium palm oleate from star fruit is mainly used as a skin conditioner, emollient and surfactant. It can soften the skin's stratum corneum, making the skin smoother and more transparent, while promoting skin metabolism to achieve a hydrated, fair and dull effect. Sodium palm oleate from star fruit itself does not directly feature foaming as its main characteristic, but as an emollient and skin conditioner, it can optimize the microenvironment on the skin surface, provide a better basis for other surfactants, and help enhance the fineness and stability of the foam, making the overall foam more uniform and lasting.

[0035] Sodium cocoamidopropionate is an amino acid surfactant and is widely used as a cleanser and skin conditioner in cosmetics. It is neutral and safe. At the same time, it has excellent foaming ability and foam stability. It can quickly produce rich and delicate foam, covering and penetrating into the skin texture, effectively cleaning the dirt and oil deep in the pores. Under the synergistic effect of Sodium Murumuru Palm Oleate, Sodium cocoamidopropionate can further enhance the richness and density of the foam, making the cleaning process more pleasant and efficient.

[0036] Disodium lauroyl glutamate is also a mild amino acid surfactant. Its weak acidity is close to the pH value of the skin, which can protect the skin barrier from damage. When used in combination with other surfactants, disodium lauroyl glutamate can enhance the durability and stability of the foam, making the foam denser and more elastic. At the same time, it can also help other ingredients penetrate the skin better and improve the skin care effect.

[0037] As an amphoteric surfactant, lauramidopropyl betaine has excellent foaming, foam stabilizing and thickening properties. It can significantly improve the foam quality of the product, making the foam more delicate, rich and lasting. When compounded with sodium cocoyl aminopropionate, disodium lauroyl glutamate and sodium murumuru palm oleate, lauramidopropyl betaine can further enhance the density and stability of the foam.

[0038] The present invention also finds that the Hypericum perforatum flower / leaf / stem extract, Capparis spinosa fruit extract and Sanguisorba officinalis root extract in the skin conditioning components have a mutually promoting effect in inhibiting the oil secretion of human sebaceous gland cells, thereby improving the overall oil control effect.

[0039] Beneficial effects of the present invention:

[0040] 1. The refreshing oil-control composition provided by the present invention has excellent performance in inhibiting the oil secretion of human sebaceous gland cells and has excellent deep oil-control effect on the skin;

[0041] 2. In the surfactant system provided by the present invention, sodium palm oleate, sodium cocoylaminopropionate, disodium lauroyl glutamate and lauroylamidopropyl betaine have good foaming power and stable and long-lasting foam when used in combination;

[0042] 3. The refreshing oil-control cleansing product provided in this application can significantly reduce the oil content of the skin, improve oily skin, and achieve oil control effect. DETAILED DESCRIPTION

[0064] Skin conditioning component performance test:

[0065] Test for inhibiting cell lipid secretion performance

[0066] Test cells: Immortalized human sebaceous gland cell line SZ95 was selected. The cell line passed the cell line quality control test and the result was qualified. The generation number of this test is: P10.

[0067] Experimental consumables: fetal bovine serum, high-glucose DMEM medium, penicillin, streptomycin, phosphate buffered saline (PBS), modified Oil Red detection kit, paraformaldehyde, isopropanol, isotretinoin, dihydrotestosterone (DHT).

[0068] Complete medium: high-glucose DMEM medium supplemented with 10% fetal bovine serum, 100 U / mL penicillin, and 100 μg / mL streptomycin;

[0069] Test sample group: complete medium containing the test samples and 1 μmol / L DHT, wherein the test samples are components 1-3 and comparison components 1-6, and the concentrations of the test samples in the complete medium are 1wt% and 2wt%;

[0070] Blank control group: complete medium;

[0071] Negative control group: complete medium containing 1 μmol / L DHT;

[0072] Positive control group: complete culture medium containing 1 μmol / L DHT and 5 μmol / L isotretinoin.

[0073] Test plan:

[0074] (1) Cell preparation: Well-grown human sebaceous gland cells were inoculated in complete culture medium in a 24-well plate, with 5 × 10 cells per well. 4 500 μL PBS solution was added to the edge wells of the well plate, and a blank control group, a negative control group, a positive control group and a test sample group were set up respectively, with three replicate wells in each group. The 24-well plate was placed at 37°C and 5% CO 2 Incubate overnight in an incubator.

[0075] (2) Administration: After overnight culture, replace the complete medium in the 24-well plate and carry out the administration. The blank control group was given 1 mL of complete medium, the sample group was given 1 mL of complete medium containing the corresponding concentration of the test sample and 1 μmol / L DHT, the positive control group was given 1 mL of complete medium containing 1 μmol / L DHT and 5 μmol / L isotretinoin, and the negative control group was given 1 mL of complete medium containing 1 μmol / L DHT. After administration, the 24-well plate was placed at 37°C and 5% CO 2 Incubate in the incubator for 48 h.

[0076] (3) Oil droplet detection: After incubation, wash with PBS, fix with 4% paraformaldehyde for 30 min, and wash with distilled water for 2 min. Wash twice and perform detection according to the instruction manual of the Oil Red Detection Kit. Use an inverted microscope and an ELISA reader to detect the oil droplets in each sample well. The data of each group are the average of three replicate wells.

[0077] Criteria:

[0078] Oil red is a fat-soluble azo dye that can specifically stain neutral lipids such as triglycerides in cells or tissues, but has a weaker staining effect on lipids such as phospholipids and steroids. When cells or tissue sections are immersed in oil red staining solution, oil red can dissolve in fat (such as lipid droplets) in cells or tissues, making them red or orange-red. The staining in tissues or cells can be observed under a microscope to compare the differences in triglyceride accumulation in each group. After staining, lipids can be extracted with 60% isopropanol, and the absorbance of the dye at 510nm can be measured for quantitative comparison. Under the same 1μmol / L DHT stimulation condition, the oil droplet content in the test sample group decreased compared with the negative control group, indicating that the sample has the ability to inhibit oil secretion at this test concentration. The results are shown in Table 1.

[0079] Table 1 Relative content and inhibition rate of oil droplets in sebaceous gland cells

[0080]

[0081] Result analysis:

[0082] Compared with the negative control group, the oil droplet content of components 1-3 showed a decrease. The inhibition rates of oil secretion of human sebaceous gland cells of components 1-3 at a concentration of 2wt% were 27.12%, 27.89% and 26.12%, respectively, indicating that the skin conditioning agent components provided by the present invention have excellent performance in inhibiting the oil secretion of human sebaceous gland cells and have excellent deep oil control effect on the skin.

[0083] Preparation of refreshing oil-control cleansing products:

[0084] Weigh accurately according to the mass percentage of the raw materials in Table 2;

[0085] (1) Add the pH adjuster into deionized water and stir to dissolve completely at room temperature to obtain phase A;

[0086] (2) adding butanediol, 1,2-hexanediol, p-hydroxyacetophenone and panthenol into deionized water, heating to 60° C., stirring and dissolving uniformly to obtain phase B;

[0087] (3) Add deionized water to the reaction container, and add sodium palm oleate, sodium cocoylaminopropionate, disodium lauroyl glutamate, lauroyl amide propyl betaine, allantoin and glycerin in sequence, heat to 83±2°C and keep warm, stir until dissolved evenly, open condensation water, stir and cool to 43±2°C, which is phase C;

[0088] (4) Add phase B, skin conditioning component 2 and polyquaternium-39 to phase C, stir and dissolve evenly, then add phase A to adjust the pH to prepare a refreshing oil-control cleansing product.

[0091] Note: “-” in the table means not added.

[0092] Performance test of refreshing oil-control cleansing products:

[0093] 1. Foaming performance test

[0094] Foam height test: The foam height of cleaning products is tested with a Roche foam meter to evaluate the foaming power. Preheat the super constant temperature water bath to 40±1℃, and keep the Roche foam meter at a constant temperature of 40±1℃. Weigh 2.5g of the sample, add 100mL of hard water (1500mg / kg hard water) and stir. After the sample is evenly dissolved, add 900mL of distilled water for use; use a 200mL quantitative funnel to absorb part of the test solution and rinse along the wall tube of the foam meter. Then take the test solution and put it into the bottom of the foam meter, align it to the standard scale to 50mL, and then use a quantitative funnel to absorb 200mL of the test solution, fix the center position of the funnel, put the test solution, and immediately record the initial foam height. After standing for 5 minutes, record the foam height again. Perform two parallel tests, and take the average of the two results within the allowable error range as the final result. Under the same test conditions, the higher the initial foam height, the better the foaming power (the initial foam height of cleansing products is generally required to be greater than 100 mm); the foam height change rate is calculated as (initial foam height - 5-minute foam height) / initial foam height × 100%. The smaller the foam height change rate after 5 minutes, the more stable and durable the foam is. The test results of the foam height test of the refreshing oil-control cleansing products prepared in Examples 1-4 and Comparative Examples 1-5 are shown in Table 3.

[0095] Table 3 Foam height test results of Examples 1-4 and Comparative Examples 1-5

[0096]

[0097] Result analysis:

[0098] It can be seen from the results of Examples 1-4 that when sodium Murraya palm oleate, sodium cocoylaminopropionate, disodium lauroyl glutamate and lauramidopropyl betaine in the surfactant system are used in combination, the refreshing oil-control cleansing product can have good foaming power and stable and long-lasting foam; it can be seen from the results of Comparative Examples 1-4 that when sodium Murraya palm oleate is lacking in the above-mentioned surfactant system, the refreshing oil-control cleansing product has poor foaming power and unstable foam; among them, Comparative Examples 1-3 replace the missing sodium Murraya palm oleate with equal amounts of sodium cocoylaminopropionate, disodium lauroyl glutamate and lauramidopropyl betaine in turn, but none of them can achieve the good effect brought by sodium Murraya palm oleate.

[0099] 2. Evaluation of oil control efficacy

[0100] Number of volunteers: 45; Age: 18-40 years old.

[0101] Skin condition: The subjects had healthy skin and no history of skin diseases or allergies.

[0102] Skin type: Mostly oily skin

[0103] Evaluation index: Facial oil

[0104] Test instrument: SEBUMETER SM 815

[0105] Test area: Forehead.

[0106] Evaluation process:

[0107] 1. Take 2.5g of the cleaning products provided in Examples 1-4 and Comparative Examples 1-5 to wash your face twice a day, once in the morning and once in the evening. Testing method: test 2 hours after cleansing on the day of testing, place the sebum box vertically on the skin for 15 seconds, and read the data value after the measured value stabilizes. Take the average integer value for each group, and 0 week is the value tested before using the product;

[0108] 2. The sebum values ​​were measured 2 weeks, 4 weeks, 6 weeks, and 8 weeks after the use of the cleansing product; the results are shown in Table 4.

[0109] Table 4 Sebum numerical detection results

[0111] Calculation formula: Grease content change rate = (grease content after using the sample - grease content before using the sample) / grease content before using the sample × 100%;

[0112] The change rate of oil content is shown in Table 5.

[0115] Result analysis:

[0116] The results show that the refreshing oil-control cleansing product provided by the present application can significantly reduce the oil content of the skin, improve oily skin, and achieve the oil control effect. The oil control effect of Examples 1-4 increases with the increase in the amount of skin conditioning components added, showing concentration dependence, which indicates the key role of skin conditioning components in cleansing products. This is consistent with the results of Comparative Example 4, in which the oil control effect of Comparative Example 4 is greatly reduced in the absence of skin conditioning components.

[0117] Comparative Examples 1-4 mainly lack sodium palm oleate of star fruit, which also leads to a decrease in the oil control performance of the cleaning product, reflecting that sodium palm oleate of star fruit has a certain oil control effect. Through its softening and conditioning effects, it helps to balance the oil secretion of the skin, thereby playing an oil control role; sodium palm oleate of star fruit is combined with amino acid surfactants and amphoteric surfactants to form dense and rich foam under mutual cooperation, increase the contact area with oil on the skin surface, make the skin soft, refreshing and comfortable, and at the same time combined with the effect of inhibiting skin oil secretion by the skin conditioning components, the simultaneous action of the two aspects achieves deep oil control.

[0118] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
