Description

Technical Field

[0001] The invention relates to the technical field of daily necessities, in particular to a novel amino acid shapeable cream soap and a preparation method thereof. Background Art

[0002] At present, the amino acid soaps on the market are all amino acid surfactant soaps obtained by combining coconut glutamic acid and a large amount of triethanolamine and then mixing them with glycerin and other alcohol substances. Large amounts of triethanolamine can cause skin irritation. Fu Lanqin from the Department of Dermatology at Peking Union Medical College Hospital explained in a study: "Triethanolamine is an alkaline substance and is mostly used in cosmetics, detergents and other items. This substance is irritating to human skin. Excessive skin contact can easily cause pain, itching and other symptoms." It also has a pungent smell.

[0003] The existing amino acid soap is soft and easily dissolved in water due to its formula structure. Generally, it will stick to the soap box or wash basin halfway through use, causing great waste and pollution.

[0004] Since the soap body is not hard enough, it can only be sold in a single round shape. The single shape cannot be as creative as traditional soaps. The lack of beauty and creativity is not conducive to marketing. Therefore, the current amino acid soap has been in the primary stage, has not been widely sold on a large scale, and has not been widely accepted and used by the public. Summary of the invention

[0005] The object of the present invention is to provide a novel amino acid sculptable cream soap to solve the problems raised in the background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A novel amino acid shapeable cream soap comprises the following raw materials in parts by weight:

[0008] Foaming component A:

[0009] 35-45 parts of sodium lauroyl glutamate;

[0010] Modeling component B:

[0011] 20-32 parts of modified glyceryl hydroxystearate core-shell material;

[0012] Other functional components C:

[0013] Vitamin C 0.1-0.6 parts;

[0014] 32-42 parts of sorbitol;

[0015] Propylene glycol 6-16 parts;

[0016] Sucrose 10-20 parts;

[0017] 1-10 parts of edible alcohol.

[0018] Furthermore, the modified glycerol hydroxystearate core-shell material is prepared in the following steps:

[0019] S1. Dissolve cinnamon oil, glyceryl hydroxystearate and polyglyceryl laurate in anhydrous ethanol, pour into a round-bottom culture bottle, homogenize under ultrasound for 12 minutes, evaporate the solvent at 60°C at a speed of 100-200 r / min for 2 hours, and place the formed smooth film in a vacuum drying oven at 30°C for 24 hours to obtain a film;

[0020] S2, adding the obtained film to a block polyether nonionic surfactant solution with a mass fraction of 10%-20% to rehydrate, stirring for 5 minutes and vortexing for 2 minutes in an ultrasonic bath at 50° C., and repeating this process twice to obtain a crude suspension;

[0021] S3. Prepare a mixed solution of γ-polyglutamic acid and hyaluronic acid, add it to the crude suspension, stir it with a stirring device for 3 hours, centrifuge it at a speed of 4000-6000r / min for 15 minutes, collect the lower precipitate, filter it, wash it, dry it in a vacuum drying oven at 4°C for 12 hours, and store it at 4°C to obtain a modified glyceryl hydroxystearate core-shell material.

[0022] It should be noted that after being dispersed in water, the block polyether nonionic surfactant can form stable micelles with the fatty acid anions released after being dissolved in water, exerting the steric hindrance effect of the macromolecular polymer to prevent the precipitation of fatty acid salts to form soap scum.

[0023] Furthermore, the particle size of the modified glycerol hydroxystearate core-shell material is 100-180 nm.

[0024] It should be noted that core-shell materials with smaller particle sizes (less than 200 nm) can achieve high embedding rates.

[0025] Furthermore, the polyglycerol laurate is one of glyceryl monolaurate, triglyceryl monolaurate, hexaglyceryl monolaurate, and glyceryl dodecanol.

[0026] It should be noted that polyglycerol monolaurate can effectively fight against Gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis).

[0027] Furthermore, in step S1, the dosage ratio of cinnamon oil, glyceryl hydroxystearate, polyglyceryl laurate and anhydrous ethanol is (1-1.74) mg: (40-50) mg: (16-20) mg: 10 mL.

[0028] It should be noted that cinnamaldehyde in cinnamon oil is the main effective antibacterial component, which has antibacterial and anti-inflammatory effects. As an unsaturated ketone, it can undergo Michael addition reaction with glutathione, thereby removing glutathione and improving the antibacterial / anti-cancer ability mediated by reactive oxygen. Cinnamon oil is positively charged and has antioxidant properties. The core-shell structure primary material in the crude suspension prepared with cinnamon oil as the core structure and glycerol hydroxystearate and polyglycerol laurate as the shell structure can synergistically inhibit bacteria on the one hand, and retain the highly plastic and shape-changing properties of glycerol hydroxystearate as a plasticizer on the other hand.

[0029] Furthermore, in step S2, the dosage ratio of the film to the block polyether nonionic surfactant solution is 70 mg:10 mL.

[0030] Furthermore, in step S3, the concentration of γ-polyglutamic acid in the mixed solution is 2 mg / mL, and the molecular weight of γ-polyglutamic acid is 700,000-1,000,000; the concentration of hyaluronic acid is 0.2 mg / mL;

[0031] It should be noted that the modified γ-polyglutamic acid / hyaluronic acid complex carries a negative charge and has strong moisturizing properties, film-forming properties, strong smoothness and sustained release ability. On the one hand, γ-polyglutamic acid has an inhibitory effect on Staphylococcus aureus and Escherichia coli; on the other hand, the negatively charged γ-polyglutamic acid / hyaluronic acid complex, as the primary material of the positively charged core-shell structure in the crude suspension, can also control the release of cinnamon oil through electrostatic adsorption of the outer layer modifier.

[0032] It should be noted that the carboxyl group of γ-polyglutamic acid is connected to the hydroxyl group of vitamin C through an ester bond, which is antioxidant and UV-resistant, further improving the stability of the soap.

[0033] Furthermore, in step S3, the volume ratio of the mixed solution to the crude product suspension is (1.05-1.1):1.

[0034] A method for preparing a novel amino acid sculptable cream soap comprises the following steps:

[0035] Step 1, heating sodium lauroyl glutamate while stirring until dissolved, controlling the temperature at 65-75°C, then adding modified glyceryl hydroxystearate core-shell material, vitamin C, sorbitol, propylene glycol, sucrose, and edible alcohol to the dissolved sodium lauroyl glutamate, stirring and heating to 80-90°C at a heating rate of 1-2°C / min, homogenizing for 3h, defoaming and cooling to 40-60°C to obtain a soap base liquid;

[0036] Step 2: Pass the soap base liquid through a 600-mesh sieve, pour it into a mold, cool it for 4-6 hours, and demold it to obtain a new type of amino acid shapeable cream soap.

[0037] It should be noted that the surfactant used is sodium lauryl glutamate, which has good cleaning, foaming, mild and environmentally friendly properties; modified glyceryl hydroxystearate core-shell material, sugar, sorbitol and propylene glycol serve as the stable structure of the system; the main material of the modified glyceryl hydroxystearate core-shell material, glyceryl lauryl hydroxystearate, is a common food emulsifier with good biosafety properties, and is also a good plasticizer, which can make the soap body dry and smooth, with moderate hardness, and will not absorb water and become soft, thus reducing waste; the addition of sugar will turn sodium lauryl glutamate into a transparent liquid state at high temperature, promote leveling during the low-temperature solidification process, ensure the uniformity of the soap body, and at the same time play the role of a skin feel regulator to a certain extent; the addition of sorbitol and propylene glycol can increase the solubility of the formula, effectively reduce the degreasing power of sodium lauryl glutamate, and play a major moisturizing role.

[0038] Furthermore, the pH of the novel amino acid sculpting cream soap is 5.6-6.

[0039] It should be noted that the present invention is weakly acidic, close to the average pH value of human skin, has excellent skin affinity, does not irritate the skin, is relatively mild, has very little irritation to the eyes, does not cause tightness after washing, makes the skin acid-base balanced, and is suitable for all skin types.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. The soap body of the present invention is dry, white, and of moderate hardness. It can be shaped by a gravity punching machine, will not absorb water and become soft, and will not leave soap scum, thus reducing waste during non-use periods, and is both practical and aesthetically pleasing.

[0042] 2. The invention is weakly acidic, close to the pH value of human skin, retains the mild properties of amino acid soap, removes the triethanolamine component in the amino acid soap that causes yellowing, does not irritate the conjunctiva and nasal mucosa, allows the face to be washed with eyes open, and the foam produced is as white, delicate and dense as cream.

[0043] 3. The components in the modified glycerol hydroxystearate core-shell material prepared by the present invention have synergistic antibacterial effects and have antibacterial activity against a variety of skin disease pathogens. At the same time, they play the role of moisturizing, sustained release, and shaping, and cooperate with other formula components to improve the stability of the soap body.

[0044] 4. The raw materials of the formula of the present invention are all biodegradable and conform to the product concept of green environmental protection. DETAILED DESCRIPTION

[0130] test:

[0131] 1. Acute eye irritation test

[0132] Test method: The patch test method for detecting human safety adopts a 48-hour closed patch test. 30 healthy volunteers with no history of allergies are selected. After cleaning the back of the subjects, 2g of the soap-based liquid prepared in Examples 1-3 and Comparative Examples 1-3 are taken, and the patch tester with the soap-based liquid is applied to the selected position on the back with a non-irritating tape. After sticking, lightly press with fingers to evenly stick it on the skin for 48 hours. The subjects are advised to keep the patch site dry within 48 hours, avoid intense exercise, scratching the patch site, prolonged sunlight exposure, etc. After 48 hours, the patch site is removed and dried. After 30 minutes, the patch marks disappear, and the product is judged under sufficient light and the irritation of the product is evaluated.

[0133] The test results are shown in Table 1.

[0137] 2. Antibacterial Test

[0138] Test soap solution: soap base solution of Examples 1-3 and Comparative Examples 1-3.

[0139] Control solution: Prepare 1 mg / ml minocycline hydrochloride solution and dilute it 100 times as the positive control solution.

[0140] Take the refrigerated Staphylococcus aureus, Escherichia coli, and Bacillus subtilis, culture them at 37°C for 24 hours, pick a single colony and transfer it to several sterilized slant culture media by streaking method and culture for 24 hours; pick the colonies of the three activated test bacteria with an inoculation loop, transfer them to LB liquid culture medium and culture them at 37°C for 8-10 hours, centrifuge and dilute with sterile saline to a bacterial count of about 1.5×10 8cfu / mL of bacterial suspension for later use. The antibacterial ability of the prepared gel was measured using the Oxford cup method. Four Oxford cups were placed symmetrically on the culture dish, 10mL of LB solid culture medium was poured in, and then 10ml of LB solid culture medium containing 1ml of bacterial suspension was poured in. After solidification, the Oxford cup was taken out, distilled water was added to 1 well as a blank control, and the test solution was added to the remaining 3 wells. Seven groups of test solutions were made for each bacterium, namely: positive control group, Examples 1-3, and Comparative Examples 1-3; the diameter of each inhibition zone was measured using a vernier caliper, and each inhibition zone was measured 3 times from different directions to take the average value.

[0149] Table 3

[0150] IV. Conclusion

[0151] 1. As can be seen from Table 1, the soap base liquids of Examples 1-3 are almost non-irritating to human skin; Comparative Example 1 is more irritating due to the use of triethanolamine; Compared with Comparative Example 1, Comparative Examples 2 and 3 are less irritating because less irritating glyceryl hydroxystearate and its primary core-shell materials are used.

[0152] 2. As can be seen from Table 2, the antibacterial properties of Examples 1-3 are significantly improved compared with Comparative Examples 1-3, and the antibacterial level is relatively close to the antibacterial ability of the positive drug; the core structure, shell structure and modifier of the modified glycerol hydroxystearate core-shell material all play a certain antibacterial effect, and the synergistic antibacterial effect of the three is greatly improved compared with the single component of Comparative Example 2 and the core-shell structure of Comparative Example 3.

[0153] 3. The existing amino acid soaps on the market are soft and easy to dissolve in water due to their formula structure. Generally, they will stick to the soap box or wash basin halfway through use, causing great waste and pollution. As shown in Table 3, the soap hardness of Examples 1-3 is maintained at a moderate level, which can improve the above problems and leave less soap scum.
