Description

Technical Field

[0001] The invention relates to the field of cosmetics, and in particular to a repairing and nourishing composition for shower gel, application thereof and shower gel. Background Art

[0002] Prior art: Chinese patent application CN118955320A, the subject matter of which is a ceramide co-crystal and its preparation method and application, proposes that ceramide and tetrahydromethylpyrimidine carboxylic acid or nicotinamide generate a co-crystal product to improve the water solubility and stability of ceramide and improve the effectiveness of ceramide on the skin.

[0003] During the development of this project, we validated the technology as an effective means of delivering the nourishing and restorative benefits of a body wash.

[0004] In subsequent studies, we found that the improvement in the restorative and nourishing efficacy was not determined solely by the co-crystal product.

[0005] Therefore, the technical problem to be solved by the present invention is: how to further improve the repairing and nourishing effect of the shower gel. Summary of the invention

[0006] One of the purposes of the present invention is to provide a repairing and nourishing composition for shower gel, wherein the composition uses two composite ceramides and niacinamide to form a cocrystal, wherein the first composite ceramide is used to form a skin lipid barrier and maintain a skin lipid bilayer structure, and the second composite ceramide is used to improve the skin's deep moisturizing ability and enhance the skin's elasticity; at the same time, the use of frankincense oil can further improve the effect of ceramide on the skin, and by using citric acid and caffeine in combination, keratin renewal and increased cell proliferation rate and cell vitality are achieved on the basis of the above functions, thereby achieving the effect of comprehensive skin repair.

[0007] Another object of the present invention is to provide application of the composition and a shower gel.

[0008] To achieve the above object, the present invention provides a repairing and nourishing composition for shower gel, comprising the following components in parts by weight:

[0009] 1-2 parts of the first composite ceramide;

[0010] 0.2-1 part of the second composite ceramide;

[0011] Niacinamide 0.1-0.2 parts;

[0012] 0.02-0.1 part of citric acid;

[0013] 0.1-0.2 parts of vegetable oil;

[0014] Caffeine 0.2-1 part;

[0015] The vegetable oil contains at least 0.02 to 0.1 parts of frankincense oil;

[0016] The first composite ceramide contains ceramide NP, ceramide AP, and ceramide EOP in a total amount of 1.5 wt%;

[0017] The second composite ceramide contains ceramide NS and ceramide NG in a total amount of 1 wt %.

[0018] The core components of the present invention are the first complex ceramide, the second complex ceramide and nicotinamide, which form a eutectic product, which can improve the stability and biological activity of the first complex ceramide and the second complex ceramide, so that the first complex ceramide can effectively build a skin lipid barrier and maintain the skin lipid bilayer structure, and the second complex ceramide can more effectively improve the deep moisturizing ability of the skin and enhance the elasticity of the skin on this basis;

[0019] At the same time, in the present invention, the amount of niacinamide used far exceeds the amount of ceramide used. Niacinamide in the formula of the present invention also plays the role of shrinking pores, replenishing water and repairing the skin barrier;

[0020] In the present invention, plant oils containing frankincense oil are used in combination. Compared with other plant oils, frankincense oil has unique effects in soothing, repairing and balancing skin oil. When it acts on the above-mentioned eutectic product, it can further optimize the skin lipid bilayer structure from the perspective of balancing skin oil secretion and improve the effect of the second complex ceramide.

[0021] In the present invention, caffeine and citric acid are used. Caffeine is a hydrophilic small molecule with extremely strong permeability. It can act on the skin quickly before ceramide, stimulate blood vessels and pore contraction, stimulate collagen and elastin, inhibit proteases, and thus improve skin blood microcirculation and water retention effects; citric acid also has rapid permeability, can promote the exfoliation of aged keratin, promote pore contraction, and stimulate cell proliferation rate; the above two can improve the skin's ability to retain moisture, skin renewal and vitality, and play an important role;

[0022] Through the above-mentioned multi-factor action, the skin is repaired and nourished from the two perspectives of the stratum corneum and the cortical membrane; among them, ceramide plays the role of lipid filling in the stratum corneum and reconstruction of the skin lipid layer, plant oils optimize the structure of the skin lipid layer and improve the protective effect on the stratum corneum, citric acid and caffeine directly act on the stratum corneum, increase the stratum corneum renewal speed, regeneration ability, cell vitality, and improve the stratum corneum's own barrier ability. Through internal and external dual repair, the purpose of the present invention is achieved.

[0023] In the above-mentioned repairing and nourishing composition for shower gel, the weight ratio of ceramide NP, ceramide AP, and ceramide EOP in the first composite ceramide is 0.5-1.5: 0.5-1.5: 0.5-1.5;

[0024] The weight ratio of ceramide NS to ceramide NG in the first composite ceramide is 0.5-1.5:0.5-1.5.

[0025] In the above-mentioned repairing and nourishing composition for shower gel, the plant oil further comprises one or more combinations of castor seed oil, olive fruit oil, sage oil, and bitter orange flower oil.

[0026] In the above-mentioned restorative and nourishing composition for shower gel, the plant oil is a combination of castor seed oil, olive oil, and frankincense oil, or a combination of sage oil, bitter orange flower oil, and frankincense oil;

[0027] The weight ratio of castor seed oil, olive oil and frankincense oil is 0.5-1.5:0.5-1.5:0.5-1.5;

[0028] The weight ratio of the sage oil, the bitter orange flower oil and the frankincense oil is 0.5-1.5:0.5-1.5:0.5-1.5.

[0029] The above two combinations have different uses. The combination of castor seed oil, olive oil and frankincense oil focuses on moisturizing and repairing, and its mechanism is based on the unique moisturizing ability of castor seed oil and olive oil; the combination of sage oil, bitter orange flower oil and frankincense oil focuses on the balance and regulation of oil secretion, and its mechanism is that both sage oil and bitter orange flower oil have obvious effects in stimulating vasoconstriction and balancing oil secretion.

[0030] From the perspective of application recommendations, the combination of castor seed oil, olive fruit oil, and frankincense oil is more suitable for severely sensitive skin; the latter is more suitable for mildly sensitive skin and normal skin.

[0031] The above-mentioned repairing and nourishing composition for shower gel includes the following components in parts by weight:

[0032] 1.2-1.8 parts of the first composite ceramide;

[0033] 0.3-0.7 parts of the second composite ceramide;

[0034] Niacinamide 0.12-0.18 parts;

[0035] 0.03-0.07 parts of citric acid;

[0036] 0.12-0.18 parts of vegetable oil;

[0037] Caffeine 0.3-0.7 parts;

[0038] The vegetable oil contains at least 0.03 to 0.07 parts of frankincense oil.

[0039] At the same time, the present invention also discloses the use of any of the above-mentioned repairing and nourishing compositions for preparing shower gel.

[0040] In addition, the present invention also discloses a shower gel containing any one of the above-mentioned repairing and nourishing compositions.

[0041] In the above-mentioned shower gel, the amount of the repairing and nourishing composition is 2.5-6.3 wt %.

[0042] In the above-mentioned shower gel, the shower gel further comprises an emulsifier, a moisturizer, and water;

[0043] The emulsifier is one or more combinations of sodium laureth sulfate, cocamidopropyl betaine, cocamide methyl MEA, sodium laureth-6 carboxylate, and ammonium lauryl sulfate;

[0044] The moisturizing agent is one or more combinations of glycerin, hyaluronic acid, PPG-28-butaneth-35, and panthenol.

[0045] The above-mentioned shower gel also includes one or more combinations of preservatives, chelating agents, inorganic salts and pearlescent agents.

[0046] Beneficial Effects

[0047] Compared with the prior art, the present invention has at least the following advantages:

[0048] Two types of composite ceramides and niacinamide are used to form a cocrystal. The first composite ceramide is used to form the skin lipid barrier and maintain the skin lipid bilayer structure. The second composite ceramide is used to improve the skin's deep moisturizing ability and enhance the skin's elasticity. At the same time, the use of frankincense oil can further enhance the effect of ceramide on the skin. By using citric acid and caffeine in combination, on the basis of the above functions, keratin renewal, cell proliferation rate and cell vitality can be achieved, thereby achieving the effect of comprehensive skin repair.

[0066] The composition corresponding to shower gel 1 is composition 1, and by analogy, the composition corresponding to shower gel 10 is composition 10.

[0067] Performance Testing

[0068] The above shower gel was subjected to a transepidermal water loss test and a heme aggregation test;

[0069] The test method is:

[0070] Subject information: There were 40 volunteers, including 17 males and 23 females, aged between 20 and 44 years old; all of them were in good health, and none of them had highly sensitive constitutions; during the experiment, all volunteers completed the above test items, and no volunteer withdrew; the 40 volunteers were randomly divided into 5 groups;

[0071] Test environment: room temperature 20~22℃, humidity 40~60%, volunteers sit quietly for 1 hour, cannot eat during this period, keep the test part exposed, and avoid touching the test part;

[0072] Marking of test areas: The test site is the arm. Each volunteer's arms are divided into 8 test areas, with 4 test areas on the left arm and 4 test areas on the right arm respectively. The 4 test areas are the inner side of the upper arm and the inner side of the lower arm, with 2 test areas each; the test area of ​​each test area is 3cm*3cm; each volunteer is tested with two samples, one sample on the left arm and one sample on the right arm, and the test is completed within one day.

[0073] Establishment of skin barrier damage in the test area: Use a low-allergenic tape tearing method to damage the skin barrier in the test area;

[0074] Product use: Dispense shower gel at 0.1g / cm 2 The amount of was applied on the test area, and the blank control area was coated with deionized water;

[0075] Data testing: 2 hours after the sample was used, the laboratory staff used the Tewameter TM Hex transepidermal water loss test instrument and the Mexameter MX 18 test instrument to test the test area;

[0076] The test results can be found in Table 3 below;

[0077] Table 3 Test results

[0078]

[0079] The average rate of change of transepidermal water loss and the rate of change of hemoglobin can reflect the effect of skin repair; the larger the absolute value of the statistical result, the more obvious the repair effect.

[0080] Result analysis:

[0081] 1. It can be seen from the experimental results of shower gel 1 to shower gel 5 that they can all play a good role in repairing the skin barrier.

[0082] 2. The experimental results of shower gel 1 and shower gel 4 show that the repair effect of shower gel 4 is 39% and 30% higher than that of shower gel 1 when frankincense oil, castor seed oil and olive fruit oil are used in combination. The reason is that castor seed oil and olive fruit oil both focus more on improving moisturizing ability, while sage oil and bitter orange flower oil both focus on vasoconstriction and balancing oil secretion. In terms of the short-term repair effect of the constructed skin barrier damage model, the effects of frankincense oil, castor seed oil and olive fruit oil are more immediate.

[0083] 3. The overall effect of shower gel 5 is worse. The reason is that the dosage of the two complex ceramides is small, and the dosage of castor seed oil and olive oil is small, which limits the improvement of the skin barrier repair effect.

[0084] 4. By comparing composition 1, composition 6 and composition 7, it can be seen that the lack of citric acid and caffeine slows down the repair speed of the skin barrier, among which the lack of caffeine has a more significant effect. In terms of direct effects, caffeine is based on its rapid permeability, improving skin microcirculation and directly improving the water retention effect. After its lack, the repair speed of the skin barrier is more significantly reduced;

[0085] In shower gel 7, after adding the missing amount of caffeine to the second complex ceramide, its performance is still significantly worse than shower gel 1; the second complex ceramide contains ceramide NS and ceramide NG, which have good deep moisturizing ability; the difference in performance between the two shows that for moisturizing promoting ingredients, improving deep and lasting moisturizing and rapid permeability and water retention effects is a comprehensive improvement measure, and the lack of any one of them cannot achieve the most perfect barrier repair effect.

[0086] Similarly, in shower gel 6, after adding the missing amount of citric acid to caffeine, its effect is still not as good as shower gel 1, indicating that these two fast-penetrating small molecules play an important role in the formula of the present invention.

[0087] 5. By comparing shower gel 8 with shower gel 1, and shower gel 9 with shower gel 4, it can be seen that frankincense oil plays an important role in the skin barrier repair process. In addition to the functions of other plant oils, it can further optimize the skin lipid bilayer structure from the perspective of balancing skin oil secretion and improve the effect of the second composite ceramide. Therefore, when shower gel 8 and shower gel 9 lack frankincense oil, their repair speeds are significantly reduced.

[0088] 6. By comparing shower gel 10 and shower gel 1, it can be seen that niacinamide, as a traditional and efficient moisturizing functional ingredient and skin barrier repair functional ingredient, is also very important in the present invention. It needs to be used in a certain amount to significantly improve the repair speed of the present invention.

[0089] 7. During the use of the above shower gel, all volunteers did not experience allergic reactions, discomfort, etc., indicating that the shower gel of the present invention is mild and safe.

[0090] The embodiments presented herein are only embodiments selected according to the combination of all possible embodiments. The appended claims should not be limited by the embodiments describing the present invention. Some numerical ranges used in the claims include sub-ranges therein, and the changes in these ranges should also be covered by the appended claims.
