Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and in particular relates to a soothing composition, an aftershave product and a preparation method thereof. Background Art

[0002] During men's daily shaving process, the friction between the shaving tools and the skin will cause certain physical damage to the skin. If you use shaving cream and other products before shaving, the residual surfactants and other ingredients will also cause certain irritation to the skin and may also trigger local inflammatory reactions, leading to burning, stinging, redness, swelling, dryness and other discomforts. These problems are especially prominent for people with sensitive skin.

[0003] Aftershave products are used to moisturize and soothe the skin, preventing irritation and dryness after shaving. However, most existing aftershave products rely on high concentrations of alcohol to achieve astringency and cooling. While this provides an instant cooling sensation, it can exacerbate dryness, irritation, and burning sensations on the skin, delaying repair. Furthermore, their single soothing ingredient often fails to comprehensively and effectively address the complex post-shaving inflammation, barrier damage, and potential infection risks. Furthermore, these products can suffer from insufficient moisturizing or a greasy feel, and they often overlook the role of promoting skin barrier repair and minor wound healing.

[0004] Therefore, the market needs a mild and low-irritation aftershave care product that can quickly and effectively soothe from multiple dimensions, moisturize and promote barrier repair. Summary of the Invention

[0005] The first object of the present invention is to provide a soothing composition which, through reasonable combination, can relieve skin irritation caused by shaving by regulating the secretion of inflammatory factors, delaying vasodilation, and repairing the skin barrier.

[0006] The second object of the present invention is to propose the use of the soothing composition in after-shave products or after-shave care products.

[0007] In order to solve the above technical problems, the first object of the present invention is achieved through the following technical solutions:

[0008] A soothing composition comprising a Norway spruce leaf extract, a Lithothamnium spurum extract, a coix seed extract, and a calendula flower extract, wherein:

[0009] 1 to 5 parts by weight, preferably 1 to 3 parts by weight, more preferably 2 parts by weight, of Norway spruce leaf extract;

[0010] 1 to 8 parts by weight of the Lithoclase extract, preferably 1 to 5 parts by weight, more preferably 3 parts by weight;

[0011] 0.05 to 2 parts by weight of coix seed extract, preferably 0.1 to 1 part by weight, more preferably 0.5 part by weight;

[0012] The amount of the marigold flower extract is 0.05 to 1 part by weight, preferably 0.1 to 1 part by weight, and more preferably 0.5 part by weight.

[0013] In the present invention, the Norway spruce leaf extract was purchased from Norture, Canada; the Lithothamnium spurum extract was purchased from Provital; the coix seed extract was from Shaanxi Ciyuan Biotechnology Co., Ltd.; and the calendula flower extract was from Xi'an Green Sky Biotechnology Co., Ltd.

[0014] Norway spruce leaf extract is rich in polysaccharides, flavonoids, polyphenols and other ingredients, which can inhibit the secretion of lipids by sebaceous gland cells. Triterpenoid components can improve the water and oil balance of the skin and reduce skin dryness and itching. In addition, inhibiting oil secretion may reduce the occurrence of inflammation to a certain extent. The extract also contains anti-inflammatory ingredients such as flavonoids, so it also has a certain anti-inflammatory effect on the skin.

[0015] Lithotruncatum sutchuenensis extract can delay vasodilation and local warming caused by external stimuli. In addition, Lithotruncatum sutchuenensis extract can repair the skin's own ability to synthesize ceramides and enhance barrier function.

[0016] Coixene ester in coix seed extract reduces skin sensitivity by inhibiting TRPV1 receptors and reduces the burning sensation caused by shaving irritation; it can also inhibit the production and secretion of downstream inflammatory factors such as IL-1β and TNF-α by regulating the NF-κB signaling pathway.

[0017] Calendula saponins and carotenoids are key functional ingredients in calendula flower extract. Carotenoids (such as lutein) inhibit IL-1β and IL-8 expression, reducing inflammation while promoting keratinocyte proliferation and accelerating the healing of minor wounds. Furthermore, the polysaccharides in calendula flower extract have a strong moisturizing effect, strengthening the skin's barrier function and preventing water loss. It also soothes dry, itchy, and sensitive skin, providing long-lasting moisture and comfort.

[0018] As an application example of the soothing composition of the present invention, the present invention provides an aftershave product comprising the soothing composition, a moisturizer, and a preservative.

[0019] The moisturizing agent includes glycerin, sorbitol, and propylene glycol. Glycerin, sorbitol, and propylene glycol jointly moisturize and reduce the stickiness of a single ingredient.

[0020] The preservatives include p-hydroxyacetophenone, hexylene glycol, and EDTA-2Na. The combination of p-hydroxyacetophenone, hexylene glycol, and EDTA-2Na forms a mild preservative system, reducing the amount of traditional preservatives used. EDTA-2Na also prevents oxidation of ingredients caused by metal ions (e.g., the loss of vitamin C).

[0021] Specifically, the aftershave product comprises the following components in percentage by weight:

[0022] The soothing composition 3-8%, glycerin 3-8%, sorbitol 1-5%, propylene glycol 3-8%, p-hydroxyacetophenone 0.1-1%, hexylene glycol 0.3-0.8%, EDTA-2Na 0.03-0.08%, and the balance is water.

[0023] The preparation method of the above-mentioned aftershave product comprises the following steps:

[0024] Mix p-hydroxyacetophenone, hexylene glycol and propylene glycol, heat to 60°C to dissolve, cool to below 45°C and mix with other ingredients, stir evenly and package.

[0025] The beneficial effects of the above technical solution of the present invention are as follows:

[0026] This invention utilizes the synergistic effects of Norway spruce leaf extract, Lithothamnolium sutchuenensis extract, Coix lachryma-jobi seed extract, and Calendula officinalis flower extract. Norway spruce leaf extract can scavenge free radicals and reduce oxidative stress, thereby alleviating inflammatory responses. Coix lachryma-jobi seed extract can modulate the NF-κB signaling pathway, thereby inhibiting the production and secretion of downstream inflammatory factors such as IL-1β and TNF-α. Calendula officinalis flower extract can reduce levels of the proinflammatory cytokines TNF-α and IL-6, and also reduce PGE2 production by inhibiting COX-2 expression. Furthermore, Calendula officinalis flower extract can increase levels of the anti-inflammatory cytokine IL-10, reduce inflammatory cell activation and the release of inflammatory mediators, thereby promoting wound healing. Lithothamnolium sutchuenensis extract can slow vasodilation and localized warming caused by external stimuli. Furthermore, Lithothamnolium sutchuenensis extract can restore the skin's ability to synthesize ceramides, enhancing its barrier function. The rational combination of these four ingredients can alleviate post-shaving skin irritation by regulating the secretion of inflammatory factors, slowing vasodilation, and repairing the skin barrier.

[0081]

[0082] Effect Experiment

[0083] 1. Anti-inflammatory effect of the composition

[0084] Testing for anti-inflammatory capacity involves the following steps:

[0085] S1. Plating: RAW264.7 cells in the logarithmic growth phase were seeded in 24-well plates at a cell density of 2×10 5 / mL, 0.5mL per well, mark the top cover of the cell plate after laying the plate, and place it in a carbon dioxide incubator for incubation for 24h;

[0086] S2. Sample treatment: After incubating the cells for 24 hours, the supernatant was aspirated and 0.5 mL of the following samples were added: ① Blank control group: DMEM medium; ② Model group: 1 μg / mL LPS (DMEM medium containing 1 μg / mL LPS); ③ Positive control group: 0.001% dexamethasone + 1 μg / mL LPS (DMEM medium containing 0.001 wt% dexamethasone and 1 μg / mL LPS); ④ Experimental groups 1-20: 0.5% composition + 1 μg / mL LPS (DMEM medium containing 0.5 wt% of the soothing composition of the Examples or Comparative Examples and 1 μg / mL LPS, respectively);

[0087] S3. Detection of inflammatory factors in the supernatant of cells of each group: After the cells were treated with the sample for 24 hours, the supernatant was aspirated into a centrifuge tube with a pipette, centrifuged at 1000 rpm for 5 minutes, the precipitate was discarded and the supernatant was aspirated. The change in the amount of inflammatory factors in the supernatant was detected using the Xinbosheng TNF-α Inflammatory Factor Detection Kit.

[0088] The results of TNF-α detection in each group are shown in Table 2.

[0089] Table 2

[0090]

[0091] Based on the TNF-α values ​​shown in Table 2, the TNF-α inhibition rate for each group was calculated, and the results are shown in Table 3. TNF-α inhibition rate (%) = (TNF-α amount in model group - TNF-α amount in experimental group) / TNF-α amount in model group × 100%. A higher TNF-α inhibition rate (%) indicates a stronger anti-inflammatory effect.

[0092] Table 3

[0093]

[0094]

[0095] From the TNF-α inhibition results of each group shown in Table 3, the TNF-α inhibition rate of experimental groups 1-6 was the highest among all experimental groups, and the TNF-α inhibition rate of experimental group 3 was the highest among experimental groups 1-6. However, as the dosage of the components continued to increase, the effect on the TNF-α inhibition rate was small. From the perspective of cost-effectiveness, Example 1 achieved the highest cost-effectiveness.

[0096] Since coix seed extract and calendula flower extract have a direct effect on TNF-α, in the above-mentioned experimental groups 7-20, the TNF-α inhibition rates of experimental groups 9-10, 12-15, and 19-20 (corresponding to corresponding ratios 3-4, 6-9, and 13-14) in experimental groups 7-20 (corresponding to corresponding ratios 1-10) were higher than those in experimental groups 7-8 and 11 (corresponding to corresponding ratios 1-2 and 5), while the TNF-α inhibition rates of experimental groups 16-18 (corresponding to corresponding ratios 10-12) were significantly higher than those in experimental groups 9-10, 12-15, and 19-20 (corresponding to corresponding ratios 3-4, 6-9, and 13-14). This proves that the combined use of coix seed extract and calendula flower extract produces a synergistic effect on the inhibition of TNF-α.

[0097] 2. Testing of the soothing, repairing and moisturizing effects of aftershave products on the human body

[0098] Application Examples 1 to 3 of the present invention and Comparative Application Examples 1 to 6 respectively provide an aftershave product comprising the following components in percentage by weight:

[0099] 5% of the soothing composition of Examples 1 to 3 or Comparative Examples 1 to 6, 5% of glycerin, 3% of sorbitol, 5% of propylene glycol, 0.5% of p-hydroxyacetophenone, 0.5% of hexylene glycol, 0.05% of EDTA-2Na, and the balance of water.

[0100] Among them, application examples 1 to 3 respectively use the soothing compositions of embodiments 1 to 3; comparative application examples 1 to 6 respectively use the soothing compositions of comparative examples 1 to 5 and 14; and a blank application example is also provided;

[0101] Preparation method of aftershave products: mix p-hydroxyacetophenone, hexylene glycol and propylene glycol, heat to 60°C to dissolve, cool to below 45°C, mix with other ingredients, stir evenly and then package.

[0102] The components and dosages of the aftershave products of the above application examples are shown in Table 4.

[0103] Table 4

[0104]

[0105]

[0106] Fifty male volunteers aged 18-45 were selected. No skin care products were applied on the day. After washing their faces, the subjects sat quietly in a constant temperature and humidity room with a temperature of 21±1°C and a humidity of 50±10% for 30 minutes.

[0107] The subjects were randomly divided into 10 groups, with 5 people in each group. They were shaved with an electric shaver and the transepidermal water loss probe Tewameter was used after shaving. TM Hex (Courage+Khazaka) and moisture probe Corneometer The CM 825 (Courage + Khazaka) instrument was used to test the initial TEWL and moisture content of each group of subjects, with the cheeks being the test site. Visia-7 was used to photograph the face, and the derived red zone images were analyzed to obtain the initial a* values.

[0108] Then, each group of subjects randomly used the aftershave products of Application Examples 1-3, Comparative Application Examples 1-6, and Blank Application Example, and marked the groups. The usage amount was about 1 mL. After 15 minutes, the various index tests were repeated to analyze the improvement of TEWL value, moisture content and a* value.

[0109] The improvement is represented by the rate of change of each value, which is calculated as follows:

[0110] The rate of change relative to the initial value (%) = |(X after use - X before use) / X before use × 100%|; the calculated data are shown in Table 5 below.

[0111] Table 5

[0112]

[0113]

[0114] From the results in Table 5, it can be seen that Application Examples 1-3 used four plant extracts, namely, Norway spruce leaf extract, Lithothamnium spurum extract, Coix lachryma-jobi seed extract and Calendula officinalis flower extract, which synergized with each other, so that the prepared aftershave products achieved significant improvements in the soothing, repairing and moisturizing effects on the human body.

[0115] Figure 1 and Figure 2 The red zone images are derived from facial images taken with Visia-7 before and after the subjects used the aftershave products of Application Example 1 and the blank application example, respectively. It can be seen from the images that the redness of the skin is reduced, indicating that the aftershave products prepared using the technical solution of the present invention have excellent soothing effects.

[0116] 3. Questionnaire survey

[0117] 30 male subjects were selected to participate in the test. The aftershave products of Application Example 1 were distributed to them. Each subject applied an appropriate amount of the product to the shaved area after shaving every day for a period of 7 days. The consumers completed a questionnaire survey on the degree of improvement in indicators such as soothing effect, moisturizing effect, irritation, and refreshing effect. The specific content of the questionnaire is shown in Table 6 below.

[0118] Table 6

[0119]

[0120] According to the questionnaire survey results in Table 6, the aftershave products of the present invention performed best in terms of soothing, refreshing, and mildness, with an effectiveness rate of 100%. The effectiveness in promoting skin smoothness, hydration, and tightening pores also reached over 90%, with significant effects. This shows that the aftershave products of the present invention have a wide adaptability and alleviate the irritation and discomfort of the skin after shaving.

[0121] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
