Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and in particular relates to a plant anti-sweat and sunscreen repairing composition and application thereof. Background Art

[0002] Sunscreen products are made by adding sunscreens that reflect or absorb ultraviolet radiation to reduce the damage to the skin caused by ultraviolet rays. Sunscreens include physical sunscreens and chemical sunscreens. To achieve adequate sunscreen effects, a large amount of sunscreens needs to be added. However, physical sunscreens and chemical sunscreens not only require a large amount of oil to dissolve, making the skin feel greasy, but also penetrate into the skin due to their small molecular weight, causing varying degrees of damage to the skin. It has been reported that some plant-based sunscreen ingredients can be added to reduce the content of physical and chemical sunscreens, thereby reducing the greasy feeling and damage of sunscreen products.

[0003] At present, the research on sunscreen products mainly focuses on reducing their irritation, enhancing their skin feel and waterproof effect, while there are fewer studies on the impact of sweating on sunscreen products. It has been reported that after daily commuting or sports activities, skin sweating will also have a certain impact on the sunscreen effect of sunscreen products. The effect of sweat on the efficacy of sunscreen is generally reflected in two aspects. On the one hand, sweat will wash off the sunscreen, resulting in a decrease in thickness; on the other hand, sweat will redistribute the sunscreen, reducing its uniformity. At present, the measures to make sunscreen products sweat-proof are mainly to improve their waterproofness. On the one hand, some oily ingredients are added to the sunscreen products, which will form an oil film after being applied to the skin. The film can provide a certain resistance and reduce the erosion of sweat on the sunscreen products; on the other hand, some water-absorbing ingredients can be added, such as sodium polyacrylate, carboxyethyl cellulose, etc. However, too much film-forming agent will not only make the skin feel of the product worse, but also have certain requirements for makeup removal after sun exposure. Sunscreen products with a high content of film-forming agents generally need to be removed with makeup remover oil. Using only makeup remover water or facial cleanser will leave a lot of residue.

[0004] It can be inferred that adding antiperspirants to sunscreen products can also reduce the impact of sweat on sunscreen products. The mainstream antiperspirant ingredients on the market are mainly aluminum salts, which can block the outlet of the human sweat duct after application to improve the sweating situation. The effect is good, but its effect period is not long, and it may cause symptoms such as inflammation, which is more likely to cause skin discomfort to some people who are allergic to chemical substances. Therefore, people should choose natural and safe plant-based antiperspirants. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a plant anti-perspiration and sunscreen repair composition and its application which has excellent anti-perspiration and sunscreen effects, good skin feel, is easy to clean, mild and non-irritating, and has after-sun repair ability.

[0006] To achieve the above objectives, in a first aspect of the present invention, the present invention provides a plant antiperspirant sunscreen repair composition, the plant antiperspirant sunscreen repair composition comprising the following components in parts by weight:

[0007] 4-7 parts of Sophora japonica fruit extract, 0.1-0.5 parts of Ilex oleifera leaf extract, 0.7-0.8 parts of Hibiscus sabdariffa flower extract, 0.1-0.5 parts of Fraxinus fraseri extract, and 0.01-0.05 parts of Potentilla flavescentis extract.

[0008] The present invention selects components in appropriate proportions, specifically Sophora japonica fruit extract, Ilex holly leaf extract, Hibiscus sabdariffa flower extract, Fraxinus chinensis extract and Potentilla officinalis extract. The five ingredients can synergize with each other, and can effectively inhibit sweating on the basis of having good resistance to ultraviolet rays, and will not clog pores while inhibiting sweating, that is, it is mild and non-irritating; at the same time, it also has excellent after-sun repair ability, can effectively restore the moisturizing property of the skin after sun exposure, improve the skin barrier ability, and can also reduce the area of ​​the red zone caused by sunburn.

[0009] Specifically, Sophora japonica fruit extract can effectively absorb UVA; Ilex holly leaf extract can effectively absorb UVB; Hibiscus sabdariffa flower extract can reduce the production of UVB-induced ROS and has an after-sun repair effect; the fraxinus in the Fraxinus chinensis extract can effectively absorb ultraviolet rays, and in addition has a capillary penetration effect, and has a certain antiperspirant effect; Potentilla flavescentis extract also has a certain antiperspirant effect; the present invention creatively discovered that when the above five ingredients are mixed and prepared in a specific mass ratio, excellent anti-sweat and sunscreen effects can be achieved at the same time, and they are mild and non-irritating. After use, they can effectively maintain good skin moisturizing properties and have excellent after-sun repair effects.

[0010] As a preferred embodiment of the plant antiperspirant and sunscreen repairing composition of the present invention, the plant antiperspirant and sunscreen repairing composition comprises the following components in parts by weight: 5-6 parts of Sophora japonica fruit extract, 0.2-0.3 parts of Ilex oleifera leaf extract, 0.7-0.8 parts of Hibiscus sabdariffa flower extract, 0.2-0.4 parts of Fraxinus fraxinus extract, and 0.02-0.03 parts of Potentilla flavescentis extract.

When the mass fraction of the components in the composition is further selected to be within the range given above, the obtained composition has a better ultraviolet absorption effect and a stronger ability to inhibit sweating. At the same time, when it is subsequently applied to the preparation of sunscreen products, the obtained sunscreen products not only have anti-sweat and sunscreen effects, but also have a good effect of maintaining skin moisturizing ability, and are non-irritating while inhibiting sweating. They can avoid the increase of the red zone area of ​​the skin after use, and can also reduce the original red zone area, thereby achieving the effect of repairing the skin.

[0012] As a preferred embodiment of the plant antiperspirant and sunscreen repairing composition of the present invention, the ratio of the sum of the masses of the Fraxinus fraseri extract and the Potentilla herbacea extract to the sum of the masses of the Sophora japonica fruit extract and the Ilex oleifera leaf extract is 1:(13-30).

[0015] The present invention has found that the ratio of the sum of the masses of the Fraxinus fraseri extract and the Potentilla herb extract to the sum of the masses of the Sophora japonica fruit extract and the Ilex oleifera leaf extract will also affect the comprehensive effect of the composition. When the ratio is further selected to be 1:(13-30), especially 1:(14.5-23.5), the comprehensive effect of the obtained product is better.

[0125] The preparation methods of the sunscreen lotions provided in Application Examples 2-13, Comparative Application Examples 1-13 and Blank Application Examples are consistent with that in Application Example 1.

[0126] Effect Example 1

[0127] Effect Examples of the Invention The performance of the plant antiperspirant and sunscreen repairing compositions prepared in Examples 1-12 and Comparative Examples 1-13 was investigated, including the following aspects:

[0128] 1. Ultraviolet absorption capacity

[0129] Take 1g of the sample and spread it evenly on 3M tape, place it in a 37℃ constant temperature box for 20 minutes, take it out and stick it on the light-transmitting side of the quartz cuvette, and use a UV spectrophotometer to detect the UV absorption value in the 280-400nm band. A UV absorption value is obtained every 10nm UV wavelength; the UV absorption value of a certain band is the arithmetic average UV absorption value of each point in the band; record the UVA and UVB absorbance of the product, and the obtained data is shown in Table 3.

[0130] 2. Antiperspirant effect

[0131] 75 volunteers were recruited and divided into 25 groups with 3 people in each group. The human sweat gland activity was measured on their palms, and the active sweat pores were stained using the starch-iodine method. The absorbent cotton was soaked in a 50% aqueous solution of the plant anti-perspirant and sunscreen repair composition and placed on the left palm. Similarly, the absorbent cotton was soaked in an equal amount of water and placed on the right palm and kept at 25°C for 30 minutes. After that, the absorbent cotton was removed and the palm surface was wiped dry. The palms were stained with a 3% iodine-alcohol solution and a 10% starch-castor oil solution. The volunteers immersed their feet in 42°C hot water for 30 minutes to induce sweating. Observe and calculate 1cm 2 The antiperspirant effect was measured by the reduction rate of active sweat pores, that is, (the number of sweat pores on the right hand - the number of sweat pores on the left hand) / the number of sweat pores on the right hand × 100%, and the calculation result was the average value of each group; the obtained data are shown in Table 3.

[0132] Table 3

[0133]

[0134]

[0135] As can be seen from Table 3, the plant anti-perspirant sunscreen repair composition provided by the present invention has good ultraviolet absorption and can also effectively inhibit sweating; specifically, the UVA absorbance of the obtained product is above 1.001, the UVB absorbance is above 1.672, and the active sweat pore reduction rate is above 30.0%;

[0136] It can be seen from Examples 1-5 and Comparative Examples 1-5 that the mass of the components has a significant effect on the performance of the product. When the mass of the components in Comparative Examples 1-5 is not within the range given in the present invention, the comprehensive performance of the obtained product is poor.

[0137] It can be seen from Example 1 and Comparative Examples 6-8 that the components in the plant antiperspirant and sunscreen repair composition are indispensable, and when any one of the components is missing, an excellent comprehensive effect cannot be achieved; it can be seen from Example 1 and Comparative Examples 9-13 that when other similar ingredients are used to replace the components in the present invention, the comprehensive performance of the obtained products also shows a significant downward trend.

[0138] Effect Example 2

[0139] The effects of the present invention are as follows: The performance of the sunscreen lotions prepared by application examples 1-13, comparative application examples 1-13 and blank application examples are explored, including the following aspects:

[0140] 1. SPF value test

[0141] The test was conducted in accordance with the requirements of the "Technical Specifications for Safety of Cosmetics" (2015 edition). 135 volunteers aged 32 to 60 were selected and divided into 27 groups, with 5 people in each group. The minimum erythema dose (MED) of the subjects' skin to ultraviolet radiation was predicted and the ultraviolet radiation dose was adjusted. A spot no less than 30 cm was selected on the back of the subject. 2 Normal skin area, (2.00±0.05)mg / cm 2 The test object is evenly applied to the above area with the dosage of 1000ml, and then the irradiation dose is selected according to the specification requirements. The irradiation is carried out in three cases: ① The test object is not applied to the test object; ② The control product (SPF value 16.1±2.4, prepared according to the standard formula of high SPF standard product P2 in the 2015 edition of the "Technical Specifications for Safety of Cosmetics") is applied; ③ The test object is applied. Observe the experimental results after 24 hours, and record the MED values ​​in the three cases respectively.

[0142] SPF value calculation method: The SPF value of the test object or blank control protecting a single subject is expressed as follows:

[0143] SPFi = MED value of protected skin / MED value of unprotected skin;

[0144] Calculate the arithmetic mean of the SPF values ​​of all subjects protected by the tested object, and retain one decimal place; the obtained data are shown in Table 4.

[0145] 2. Sweat-proof ability test

[0146] Refer to the SPF value test, the difference is that the subjects need to exercise for 40 minutes before the test and wait for the skin to dry before the test; record the SPF value, and the obtained data is shown in Table 4;

[0147] At the same time, calculate the change rate of SPF value before and after exercise, which is SPF value before and after exercise = (SPF value before exercise - SPF value after exercise) / SPF value before exercise × 100%.

[0148] 3. PFA value test

[0149] The test was conducted in accordance with the requirements of the "Technical Specifications for Safety of Cosmetics" (2015 edition). 135 volunteers aged 32 to 60 were selected and divided into 27 groups, with 5 people in each group. The minimum melanization dose (MPPD) of the subjects' skin to ultraviolet radiation was predicted and the ultraviolet radiation dose was adjusted. A spot no less than 30cm on the back of the subject was selected. 2 Normal skin area, (2.00±0.05)mg / cm 2 The test object was evenly applied to the above area with the dosage of 1000ml, and then the UVA exposure amount was selected according to the specification requirements. The exposure was carried out in three cases: ① The test object was not applied to the test object; ② The control substance (PFA value 12.7±2.0, prepared according to the S2 formula in the ISO 24442 method) was applied; ③ The test object was applied. The experimental results were observed after 3 hours, and the MPPD values ​​in the three cases were recorded respectively.

[0150] PFA value calculation method: The PFA value of the test substance or reference substance protecting a single subject is expressed as follows:

[0151] PFAi = MPPD value of protected skin / MPPD value of unprotected skin;

[0152] The arithmetic mean of the PFA values ​​of all subjects protected by the tested object was calculated, and the result was rounded to one decimal place. The results are shown in Table 4.

[0153] 4. TEWL and a* value improvement test

[0154] Select a number of volunteers aged 18-45 who have been exposed to ultraviolet light. No skin care products were applied on the day of the visit. After washing their faces, the subjects sat quietly in a constant temperature and humidity room at 21±1℃ and 50±10% for 30 minutes. Use Visia 7 to take facial photos, perform image analysis on the exported red zone images, and obtain the a* value; use the skin transepidermal water loss probe to measure the skin transepidermal water loss. TM Hex (Courage+Khazaka) tests the initial facial TEWL value. 135 subjects with an initial facial a* value of more than 15 were screened and divided into 27 groups, with 5 people in each group. Every day when going out, they randomly used the sunscreen products in the application example on their entire face. TEWL tests and Visia 7 photography were performed on the 7th and 14th days. The improvement of each volunteer's TEWL and a* value on days 0, 7, and 14 was analyzed. The improvement is represented by the improvement rate of each value, and the calculation method is as follows:

[0155] Improvement rate relative to the initial value = |(X 使用后 -X 使用前 ) / X 使用前 ×100%|; The results are shown in Table 4.

[0156] Table 4

[0157]

[0158]

[0159] As can be seen from Table 4, the sunscreen lotion provided by the present invention has high sun protection ability and anti-sweat effect, and also has excellent after-sun repair effect; specifically, the SPF value of the obtained product is above 40.8, the PFA value is above 15.5, the SPF value change rate after waterproofing is below 49.36%, the TEWL improvement rate after 14 days of use is above 11.81%, and the a* value improvement rate is above 11.54%;

[0160] It can be seen from Application Examples 1-5 and Comparative Application Examples 1-5 that the mass fraction of the components in the plant antiperspirant and sunscreen repair composition has a significant effect on the performance of the product. When the mass fraction of the components in Comparative Application Examples 1-5 is not within the range given in the present invention, the comprehensive effect of the obtained product is significantly reduced.

[0161] It can be seen from Application Example 1 and Comparative Application Examples 6-8 that the components in the plant antiperspirant and sunscreen repair composition are indispensable; it can be seen from Application Example 1 and Comparative Application Examples 9-13 that when other similar ingredients are used to replace the components in the present invention, the comprehensive performance of the obtained products shows a significant downward trend;

[0162] In addition, the comparison charts of D0, D7, and D14 days using the sunscreen lotion in Application Example 1 and the blank application example are as follows: Figure 1-2 As shown, from Figure 1-2 It can also be clearly seen that the sunscreen lotion provided in Application Example 1 of the present invention achieves excellent results.
