Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, in particular to a men's aftershave soothing composition suitable for sensitive skin and application thereof. Background Art

[0002] Shaving is one of the steps in men's daily grooming. However, what is shaved during shaving is not only the beard, but also the stratum corneum. Studies have shown that 20% of the substances removed by men when shaving are skin. If the corresponding parts are not cared for in time after shaving, some skin problems will occur, such as skin irritation, barrier damage, etc., and tiny wounds may be caused during shaving, which are easily infected by bacteria and cause inflammation. Shaving will also make the skin rough and dry, which will aggravate the irritation to the skin. In addition, compared with women, men's skin has the characteristics of uneven morphology and roughness, higher transepidermal water loss, slow wound healing, larger pores and higher skin temperature. The skin around the hair follicles in the beard area is highly sensitive to mechanical and thermal stimulation, which is even more so for people with sensitive skin.

[0003] Aftershave care products generally contain soothing ingredients that help relieve the pain of the skin after shaving. In addition, they also contain some moisturizing ingredients to restore facial moisture and improve the skin barrier. However, current aftershave care products mainly focus on soothing and moisturizing after shaving. There are few studies on aftershave products for men with sensitive skin, and even fewer aftershave products that consider improving skin smoothness. At the same time, existing aftershave care products generally contain alcohol and are not suitable for people with sensitive skin. Therefore, seeking a aftershave care product suitable for men with sensitive skin has become a technical problem that needs to be solved urgently in this field. Summary of the invention

[0004] Based on this, the purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a men's aftershave soothing composition and application suitable for sensitive skin.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] In a first aspect, the present invention provides a men's aftershave soothing composition suitable for sensitive skin, the composition comprising kangaroo paw extract, Lespedeza lespedeza extract, Vitex agnus-castus extract and Alnus alnus leaf extract.

[0007] Kangaroo paw extract is rich in polysaccharides and amino acids, which can neutralize free radicals and reduce the damage of oxidative stress to skin cells. In addition, kangaroo paw extract can also stimulate the activity of fibroblasts, promote the production of collagen, make the skin more firm and elastic, and reduce the formation of wrinkles. Lespedeza extract is rich in flavonoids, which is a natural antioxidant with significant antioxidant effect. It can neutralize free radicals and reduce oxidative damage to skin cells, thereby delaying aging. In the present invention, as a cooling raw material, it can reduce skin temperature and reduce skin irritation. Vitex agnus-flowering extract is a flavonol derivative, which also has antibacterial and anti-inflammatory effects; Vitex agnus-flowering extract is also rich in a variety of antioxidant ingredients, which can help protect the skin from environmental pollution and ultraviolet damage. Alnus alnus leaf extract is rich in terpenes and flavonoids, which can resist the damage of free radicals, protect skin health, slow down the aging process, and also have a certain anti-inflammatory effect, which can reduce the inflammatory response of the skin and help maintain the stable state of the skin.

[0008] The inventors have found through experiments that when the above-mentioned plant extracts are specifically combined to form a composition, the composition has synergistic effects such as long-lasting moisturizing, cooling and soothing, and improving skin roughness, and is suitable for use by sensitive men after shaving.

[0009] As a preferred embodiment of the first aspect, the weight portion of the kangaroo paw extract is 1-6 parts, the weight portion of the Lespedeza bicolor extract is 1-8 parts, the weight portion of the Vitex agnus-castus extract is 0.1-2 parts, and the weight portion of the Alnus alnus leaf extract is 0.1-1 parts.

[0010] As a preferred embodiment of the first aspect, the weight portion of the kangaroo paw extract is 2-4 parts, the weight portion of the Lespedeza bicolor extract is 2-6 parts, the weight portion of the Vitex agnus-castus extract is 0.3-1.5 parts, and the weight portion of the Alnus alnus leaf extract is 0.4-0.8 parts.

[0011] The inventors found in actual compatibility experiments that the addition amount of kangaroo paw extract, lespedeza extract, vitex agnus-castus extract and alnus leaf extract affects the comprehensive effect of the final prepared aftershave soothing composition. When it is within the above specific range, the comprehensive effect of the soothing composition is the best.

[0012] As a preferred embodiment of the first aspect, the weight ratio of the kangaroo paw extract, Lespedeza bicolor extract, Vitex agnus-castus extract and Alnus alnus leaf extract is: (1-3):(2-3):(0.5-1):(0.3-1).

[0013] As a preferred embodiment of the first aspect, the weight ratio of the kangaroo paw extract, Lespedeza bicolor extract, Vitex agnus-castus extract and Alnus alnus leaf extract is 2:2.5:0.6:0.5.

[0014] The inventors found in actual compatibility experiments that the weight ratio of kangaroo paw extract, lespedeza extract, vitex agnus-castus extract and alnus leaf extract affects the comprehensive effect of the final prepared aftershave soothing composition. When the weight ratio is within the above-mentioned specific range, the comprehensive effect of the soothing composition is better. And the best effect is achieved when the weight ratio is: 2:2.5:0.6:0.5.

[0015] As a preferred embodiment of the first aspect, the Alnus poplar leaf extract is prepared by the following method:

[0016] (1) drying and crushing the Alnus populus leaves to obtain powder;

[0017] (2) refluxing the powder with ethanol to obtain an extract;

[0018] (3) filtering, concentrating and drying the extract to obtain the Alnus alnus leaf extract.

[0019] As a preferred embodiment of the second aspect, the concentration of ethanol in step (2) is 80% (v / v), and the amount of ethanol added is 30 times that of the powder; the reflux extraction is specifically: reflux extraction is performed twice at 60°C, each extraction is 1 hour.

[0020] In a second aspect, the present invention provides use of the soothing composition according to the first aspect in preparing skin products.

[0021] In a third aspect, the present invention provides a skin product, comprising the soothing composition according to the first aspect.

[0022] As a preferred embodiment of the third aspect, the skin product includes any one of aftershave, lotion, emulsion, cream, eye cream, eye mask, essence, and spray.

[0023] As a preferred embodiment of the third aspect, the aftershave lotion comprises the following components in percentage by mass: 4-10% of the above, 3-8% of glycerol, 1-6% of sorbitol, 3-8% of propylene glycol, 0.4-0.6% of p-hydroxyacetophenone, 0.4-0.6% of hexylene glycol, 0.04-0.06% of EDTA-2Na, and the balance is water.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The present invention finds that mouse claw extract, Lespedeza pedunculata extract, Vitex agnus-castus extract and Alnus alnus leaf extract have a synergistic effect within a certain ratio range, and a composition of specific combinations thereof can solve the skin problems of men with sensitive skin after shaving. For example, after shaving, men's skin is damaged by mechanical friction of the blade, which on the one hand increases the skin temperature and on the other hand makes the skin feel tingling, and the composition of the present invention can not only reduce the skin temperature, but also relieve the tingling sensation of the skin, so it has the effect of soothing and relieving pain; men's skin becomes rough and uneven due to long-term shaving, and the pores are damaged and become coarse, and the composition of the present invention can not only improve the roughness of the skin and enhance the smoothness of the skin, but also shrink the pores and make the skin smoother; in addition, after shaving, men's skin surface is mechanically damaged, which damages the skin barrier and makes the skin drier, and the combination of the present invention has the effect of long-lasting moisturizing, which can increase the water content of the skin and improve the dry state of the skin. Therefore, the composition of the present invention can reduce the damage caused by the shaving process, relieve the pain after shaving, and make the skin smooth after long-term use; in addition, the aftershave soothing composition is composed of plant ingredients, and no alcohol is added to the aftershave care product, which is more suitable for people with sensitive skin.

[0050] Application Examples

[0051] 1. Tests on the cooling effect, smoothness, moisturizing, TEWL and a* value improvement of aftershave containing the composition:

[0052] The compositions of Examples 1-5 and Comparative Examples 1-16 were prepared into aftershave products, and the preparation method was as follows:

[0053] Aftershave formula: 10% of the composition, 5% of glycerol, 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. Aftershave products of application examples 1-5 and comparative application examples 1-16 were prepared respectively.

[0054] A number of male volunteers aged 18-45 were selected. No skin care products were applied on the day of the visit. The subjects washed their faces and sat quietly in a constant temperature and humidity room at 21±1℃ and 50±10% for 30 minutes.

[0055] Use Visia-7 to take facial photos, perform image analysis on the exported red zone images, and obtain the a* value (measure the degree of facial redness. A decrease in the a* value indicates that facial redness has improved, which has a soothing effect); use the skin surface texture testing system VisioScan (VC20plus, Courage and Khazaka) to test the cheek area and analyze the skin smoothness; use the skin transepidermal water loss probe to measure the skin surface texture. TM Hex (Courage+Khazaka) and moisture probe CM 825 (Courage+Khazaka) tests the initial facial TEWL value and moisture content.

[0056] Then, the volunteers were exposed to direct sunlight outdoors for 20 minutes, and the facial temperature of the volunteers was tested using a surface temperature thermometer; the subjects were randomly divided into 21 groups, with 5 people in each group, and the application examples and comparative application examples provided by the present invention were randomly applied to the entire face, and the facial temperature was tested again after 10 minutes, and the temperature reduction after use compared with that before use was calculated, and the calculation results were averaged; calculation method: temperature reduction value (°C) = skin temperature after irradiation (°C) - skin temperature after using the composition (°C).

[0057] According to the above grouping, the subjects were asked to use the application example and the application comparison products every day, and each index was tested on the 7th and 14th days respectively, and the improvement of each volunteer's moisture content, TEWL value, a* value on the 7th and 14th days and skin smoothness on the 14th day was analyzed. The improvement is represented by the improvement rate of each value, and the calculation method is as follows:

[0058] Improvement rate relative to the initial value (%) = |(X 使用后 -X 使用前 ) / X 使用前 ×100%|; The calculated data are shown in Table 3:

[0059] Table 3: Skin smoothness, moisture content, TEWL value, a* value, and temperature reduction of volunteers in each group

[0060]

[0061] 2. Test the cooling effect, as follows:

[0062] The compositions of Examples 1-3, Comparative Examples 5-6, 9-10, and 12 are prepared into aftershave products, and the preparation method is as follows:

[0063] Aftershave formula: 10% of the composition, 5% of glycerol, 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. Aftershave products of application examples 1-3 and application comparison examples 5-6, 9-10, and 12 were prepared respectively.

[0064] Test method: 24 volunteers were selected and divided into 8 groups, 3 people in each group. The surface temperature thermometer was used to test the cheek temperature of the subjects before shaving, after shaving, and after using shaving products. Calculation method: temperature reduction value (℃) = temperature after shaving (℃) - temperature after using shaving products (℃); the results are shown in Table 4:

[0065] Table 4: Cooling effect test results

[0066]

[0067] 3. The above effect examples verify that the composition of Example 1 has the best applicability and soothing effect on consumers with sensitive skin. Therefore, the combination of Example 1 was used to prepare a product for testing, as follows:

[0068] The composition of Example 1 was prepared into an aftershave product. Aftershave formula: 10% of the composition of Example 1, 5% of glycerol, 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 was water.

[0069] The preparation method is as follows: after mixing 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 then package.

[0070] 30 male subjects with sensitive facial skin and recent sensitive skin symptoms were selected to participate in the test, and the product was distributed to them. Each subject applied an appropriate amount of the aftershave product of the present invention to the corresponding parts after shaving every day, and conducted a 28-day sensitive skin applicability test. The consumers completed a questionnaire survey on the improvement degree of indicators such as soothing effect, skin smoothness, irritation, and refreshing effect.
