Description

Technical Field

[0001] The present invention relates to the technical field of skin care products, and in particular to a facial cleansing composition containing natural plant ingredients, a preparation method and application thereof. Background Art

[0002] Currently, facial cleansers on the market are primarily categorized as soap-based (e.g., potassium hydroxide + fatty acids), amino acids (e.g., sodium cocoyl glycinate), SLS / SLES (sodium lauryl sulfate), and APG (alkyl glucoside). Soap-based and SLS / SLES cleans strongly, but are also highly irritating. Long-term use can damage the sebum membrane, leading to the "more oily" effect. Amino acids and APG are gentle and low-irritation, suitable for sensitive skin, but their cleansing power is weaker, making them difficult to meet the cleansing needs of oily skin types. This suggests that current facial cleansers lack the ability to balance cleansing power and irritation. Summary of the Invention

[0003] The present invention provides a facial cleansing composition containing natural plant ingredients, a preparation method thereof, and an application thereof, in order to solve the technical problem that current facial cleansing products cannot achieve both cleaning power and irritation.

[0004] In a first aspect, an embodiment of the present invention provides a facial cleansing composition containing natural plant ingredients, comprising the following raw materials in percentage by mass:

[0005] Surfactant 15% to 40%, natural active ingredient 1.5% to 4%, preservative 0.5% to 2.5%, thickener 0.5% to 2%, antioxidant 0.05% to 0.15%, pH adjuster as needed, balance deionized water;

[0006] The surfactant is composed of tea seed saponin, sodium cocoyl glycinate and decyl glucoside in a mass ratio of (1-2.5): (3-6): (2-5); the natural active ingredients are composed of bletilla striata gum, sanguisorba officinalis extract and honeysuckle extract in a mass ratio of (0.5-2): (0.3-1): (0.3-1).

[0007] Tea seed saponin, a natural active ingredient extracted from tea seeds (Camellia oleifera or related plants of the Theaceae family), belongs to the class of triterpenoid saponins and is a natural surfactant. Tea seed saponin foams quickly (foaming within 5 seconds) and has a cleansing power similar to SLES, but with only 1 / 10 the irritation.

[0008] The bletilla striata gum involved in the present invention is a mixture of bletilla striata extract (bletilla striata polysaccharide) and xanthan gum obtained by cross-linking with genipin. Bletilla striata polysaccharide forms a 3D network structure, absorbs oil within 10 seconds (the adsorption amount is 3 times its own weight), and no residue is left after rinsing. In addition, bletilla striata polysaccharide has a moisturizing and soothing effect, and the gum can repair the stratum corneum and reduce transepidermal water loss.

[0009] The Sanguisorba officinalis extract involved in the present invention is an extract of the perennial herb Sanguisorba officinalis of the Rosaceae family. The Sanguisorba officinalis extract is rich in tannins and tannic acid, has the effects of mildly shrinking pores, controlling oil and astringing, and can promote the synthesis of stratum corneum lipids and relieve dryness after cleansing.

[0010] The honeysuckle extract involved in the present invention is an extract of a semi-evergreen twining vine plant (Lonicera japonica) of the genus Lonicera of the family Caprifoliaceae. The main component of the extract is chlorogenic acid, which can penetrate hair follicles in 30 seconds, inhibit acne bacteria, and is suitable for children without irritation.

[0011] In some embodiments, the mass ratio of the tea seed saponin, sodium cocoyl glycinate and decyl glucoside is 1.5:4:3.

[0012] In some embodiments, the mass ratio of the Bletilla striata polysaccharide, the Sanguisorba officinalis extract and the Lonicera japonica extract is 1:0.5:0.5.

[0013] In some embodiments, the bletilla striata gum is prepared by mixing bletilla striata polysaccharide and xanthan gum in a mass ratio of 1:(0.2-0.5), and then adding genipin for cross-linking.

[0014] Optionally, the preparation steps of Bletilla striata glue include:

[0015] Wash the tubers of Bletilla striata and dry them at 50°C until the moisture content is less than 10%. Crush them into 40-60 mesh pieces, defatted with n-hexane, and air-dried for later use. Treat the defatted residue with cellulase for 1 hour, then add 15-20 times the amount of water, heat at 90-95°C for 3-4 hours, filter while hot, and concentrate the filtrate under reduced pressure to 1 / 5 of its original volume.

[0016] Chloroform and n-butanol in a volume ratio of 4:1 were added to the concentrate, and after shaking for 30 minutes, the protein layer was removed by centrifugation at 4000 rpm for 15 minutes, and the process was repeated until no white interface appeared. Activated carbon was then added and stirred at 70°C for 30 minutes, and the mixture was filtered. Three volumes of 95% ethanol were slowly added to the filtrate, and the mixture was allowed to stand at 4°C for 12 hours. The precipitate was collected by centrifugation at 6000 rpm for 20 minutes, washed twice with anhydrous ethanol, and then dehydrated and dried in a vacuum to obtain Bletilla striata polysaccharide.

[0017] Bletilla striata polysaccharide and xanthan gum were mixed at a mass ratio of 1:(0.2-0.5), and 0.02% genipin was added and reacted for 2 hours to obtain Bletilla striata gum.

[0018] In some embodiments, the tannic acid content in the Sanguisorba officinalis extract is greater than 40%.

[0019] Optionally, the extraction step of the Sanguisorba officinalis extract comprises:

[0020] The dried Sanguisorba officinalis root was crushed into 40-60 mesh, and the solid-liquid ratio of the Sanguisorba officinalis root to 50%-70% ethanol aqueous solution was 1:(10-15), and the temperature was controlled at 60°C-70°C for 2h-3h under dynamic reflux extraction; coarse filtration was performed with a 200-mesh filter cloth, and then fine filtration was performed with a 0.45 μm microporous membrane, and rotary evaporation was performed at 50°C-60°C to concentrate the solution to 1 / 5 of the original volume;

[0021] The crude extract was passed through a macroporous adsorption resin column at a flow rate of 2 BV / h, then washed with 3 BV of pure water, and eluted with 70% ethanol (containing 0.1% citric acid) at a flow rate of 1 BV / h; the eluate was rotary evaporated to obtain a tannic acid-enriched (greater than 40%) Sanguisorba officinalis extract.

[0022] In some embodiments, the preservative includes one or more of phenoxyethanol, pentylene glycol, 1,2-hexanediol, caprylyl glycol and caprylyl glycol; the antioxidant includes vitamin E and EDTA-2Na to prevent oxidizable components such as tannic acid in the composition from oxidizing and discoloring; the thickener includes but is not limited to xanthan gum, carbomer and cellulose thickener.

[0023] In a second aspect, an embodiment of the present invention further provides a method for preparing the above-mentioned facial cleansing composition containing natural plant ingredients, comprising:

[0024] Heat deionized water to 70-75°C, add thickener, and stir until completely dissolved to form a homogeneous aqueous matrix;

[0025] Mix tea seed saponin, sodium cocoyl glycinate and decyl glucan, slowly add a small amount of 40°C deionized water, and stir until completely dissolved to obtain a surfactant solution;

[0026] Mixing bletilla striata gum, sanguisorba officinalis extract and honeysuckle extract, adding a small amount of deionized water, and homogenizing and dispersing until no particles are left to obtain a natural active ingredient mixture;

[0027] Add the surfactant solution to the aqueous phase matrix, control the temperature at 60°C to 65°C, stir and mix for 15 to 20 minutes, then add the natural active ingredient mixture, continue stirring for 10 minutes, add the preservative and antioxidant, and stir for 5 minutes, then add the pH adjuster to adjust the pH to 5.5 to 6.5, cool to room temperature, filter to remove impurities, and obtain a cleansing composition.

[0028] In a third aspect, an embodiment of the present invention further provides a use of the above-mentioned facial cleansing composition containing natural plant ingredients in the preparation of a facial cleansing product, wherein the facial cleansing product is a facial cleanser, a facial mousse, a facial cleansing gel or a facial cream.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention uses tea seed saponin, sodium cocoyl glycinate and decyl glucoside as surfactants, which can enhance the cleaning power of the cleansing composition and keep it mild and non-irritating, meeting long-term cleaning needs; uses white hyacinth gum, sanguisorba officinalis extract and honeysuckle extract as natural active ingredients to improve the oil-control and astringent ability of the surfactant, and enable the cleansing composition to have moisturizing, repairing and antibacterial and anti-inflammatory effects.

[0077] 1. Irritation test

[0078] The RBC hemolysis test is an alternative to the rabbit eye irritation test. It measures the hemolysis concentration (HC50) and the hemoglobin denaturation index (DI) and calculates the ratio (L / D) between the HC50 and DI to assess the damage to ocular tissue cells caused by chemicals. Test results are evaluated according to the RBC test method and grading criteria of the European Centre for Validation of Alternative Methods (ECVAM). The grading criteria are shown in Table 1, and the test results are shown in Table 2.

[0079] Table 1 Irritation classification standards

[0080] L / D Grading ＞100 Non-irritating 10<L / D≤100 Slightly irritating 1<L / D≤10 Mild irritant 0.1<L / D≤1 Moderate irritation L / D≤0.1 Severe irritant

[0083] As shown in Table 2, the facial cleansing compositions prepared in Examples 1 to 3 are non-irritating and meet the needs of users for long-term use.

[0084] 2. Cleaning power test

[0085] The cleansing compositions of Examples 1 to 3 and Comparative Examples 1 to 7 were prepared into cleansing milks and tested at a temperature of 25±1°C and a humidity of 55±5%. The skin oil content of the test area was measured using a Sebumeter SM815 before and after application of the cleansing milk samples. The cleaning power was calculated as (A1-A2) / A1×100%, where A1 represents the skin oil content before application of the cleansing milk and A2 represents the skin oil content after application of the cleansing milk. The cleaning power results are shown in Table 3.

[0086] Table 3 Cleaning power test results

[0087]

[0088] As shown in Table 3, Examples 1 to 3 all achieved cleaning performance exceeding 85% and were non-irritating. Comparative Examples 1 and 7, while non-irritating, were not as effective as Example 1. Comparative Example 2, while having a high cleaning performance, was slightly irritating and not suitable for long-term use. Comparative Examples 3 to 6 also had poor cleaning performance.

[0089] 3. Moisturizing test

[0090] In the "cleansing power test", the skin moisture content of the test area was tested by using a skin moisture tester Testtheskinstatus before using the cleanser sample and after 0 hours, 1 hour and 2 hours of use.

[0091]

[0092]

[0093] As shown in Table 4, the moisture retention capacity of Examples 1 to 3 is better than that of Comparative Examples 1 to 7. As shown in Comparative Examples 3 to 4, the addition of natural active ingredients can significantly improve the moisturizing capacity of the cleansing composition.

[0094] In summary, the cleansing compositions of Examples 1 to 3 can balance cleansing power and irritation. Tea seed saponin, sodium cocoyl glycinate and decyl glucoside as surfactants have a synergistic effect in skin cleansing. Bletilla striata gum, Sanguisorba officinalis extract and Honeysuckle extract are used as natural active ingredients to enhance the oil-control and astringent ability of the surfactants, and enable the cleansing compositions to have moisturizing, repairing, antibacterial and anti-inflammatory effects.

[0095] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The specific embodiments described above further illustrate the objectives, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. In particular, it should be noted that any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of protection of the present invention for those skilled in the art.
