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 object, in the first aspect of the present invention, the present invention provides a plant anti-sweat, sunscreen and repair composition, and the plant anti-sweat, sunscreen and repair composition comprises the following components in parts by mass:

[0007] 4-7 parts of Sophora japonica fruit extract, 0.1-0.5 parts of Ilex cornuta Lindl. var. fortunei (S. Y. Hu) S. Y. Hu leaf extract, 0.7-0.8 parts of Hibiscus sabdariffa L. flower extract, 0.1-0.5 parts of Cortex Fraxini extract, 0.01-0.05 parts of Potentilla chinensis Ser. extract.

[0008] By selecting components in appropriate proportions, specifically Sophora japonica fruit extract, Ilex cornuta Lindl. var. fortunei (S. Y. Hu) S. Y. Hu leaf extract, Hibiscus sabdariffa L. flower extract, Cortex Fraxini extract and Potentilla chinensis Ser. extract, these five components can synergistically enhance each other's effects. On the basis of having good resistance to ultraviolet rays, they can effectively inhibit sweating, and will not clog pores while inhibiting sweating, that is, they are mild and non-irritating; at the same time, they also have excellent post-sun repair ability, can effectively restore the moisture retention of the skin after sun exposure, improve the skin barrier ability, and can also reduce the area of red areas caused by sunburn.

[0009] Specifically, Sophora japonica fruit extract can effectively absorb UVA; Ilex cornuta Lindl. var. fortunei (S. Y. Hu) S. Y. Hu leaf extract can effectively absorb UVB; Hibiscus sabdariffa L. flower extract can reduce the production of ROS induced by UVB and has a post-sun repair effect; aesculin in Cortex Fraxini extract can effectively absorb ultraviolet rays, and in addition, it has a capillary penetration effect and has a certain anti-sweating effect; Potentilla chinensis Ser. extract also has a certain anti-sweating effect; the present invention creatively discovers that when the above five components are mixed and prepared in a specific mass ratio, excellent anti-sweat and sunscreen effects can be achieved simultaneously, and it is mild and non-irritating. After use, it can effectively maintain the good moisture retention of the skin and has excellent post-sun repair effects.

[0010] As a preferred embodiment of the plant anti-sweat, sunscreen and repair composition of the present invention, the plant anti-sweat, sunscreen and repair composition comprises the following components in parts by weight: 5-6 parts of Sophora japonica fruit extract, 0.2-0.3 parts of Ilex cornuta Lindl. var. fortunei (S. Y. Hu) S. Y. Hu leaf extract, 0.7-0.8 parts of Hibiscus sabdariffa L. flower extract, 0.2-0.4 parts of Cortex Fraxini extract, 0.02-0.03 parts of Potentilla chinensis Ser. extract.

[0011] The research of the present invention finds that the mass parts of the components in the plant anti-sweat sunscreen repair composition will also affect the comprehensive performance of the composition. When further selecting the mass parts of the components in the composition within the range given above, the obtained composition has a better ultraviolet absorption effect, a stronger ability to inhibit sweating. At the same time, when subsequently applied to the preparation of sunscreen products, the obtained sunscreen products not only have the effects of anti-sweat and sunscreen, but also have a good effect of maintaining skin moisturizing ability, and have no irritation while inhibiting sweating, can avoid the increase in the area of skin red zones after use, and can also reduce the originally generated red zone area, achieving the effect of repairing the skin.

[0012] As a preferred embodiment of the plant anti-sweat sunscreen repair composition of the present invention, the ratio of the sum of the masses of the ash bark extract and the potentilla chinensis extract to the sum of the masses of the sophocarpine extract and the ilicifolia leaf extract of ilex cornuta is 1:(13 - 30).

[0013] Preferably, the ratio of the sum of the masses of the ash bark extract and the potentilla chinensis extract to the sum of the masses of the sophocarpine extract and the ilicifolia leaf extract of ilex cornuta is 1:(14.5 - 23.5).

[0014] Exemplarily, the ratio of the sum of the masses of the ash bark extract and the potentilla chinensis extract to the sum of the masses of the sophocarpine extract and the ilicifolia leaf extract of ilex cornuta can be any point value or any two-point range value between 1:(14.5 - 23.5), such as 1:14.5, 1:15.5, 1:16.5, 1:17.5, 1:18.5, 1:19.5, 1:20.5, 1:21.5, 1:22.5, 1:23.5, etc.

[0015] The research of the present invention finds that the ratio of the sum of the masses of the ash bark extract and the potentilla chinensis extract to the sum of the masses of the sophocarpine extract and the ilicifolia leaf extract of ilex cornuta will also affect the comprehensive effect of the composition. When further selecting the ratio 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 by Application Examples 2-13, Comparative Application Examples 1-13 and Blank Application Example are the same as that of Application Example 1.

[0126] Effect Example 1

[0127] The effect example of the present invention explores the performance of the plant anti-sweat sunscreen repair compositions prepared in Examples 1-12 and Comparative Examples 1-13, including the following aspects:

[0128] 1. Absorbing ability to ultraviolet rays

[0129] Take 1 g of the sample and evenly apply it on a 3M tape paper. Place it in an incubator at 37°C for 20 min, then take it out and attach it to the light-transmitting side of a quartz cuvette. Use a UV spectrophotometer to detect the UV absorption value in the wavelength range of 280 - 400 nm. Obtain a UV absorption value every 10 nm of the UV wavelength; the UV absorption value of a certain wavelength band is the arithmetic mean UV absorption value of each point within that band; record the UVA and UVB absorbance of the product, and the obtained data is shown in Table 3.

[0130] 2. Antiperspirant effect

[0131] Recruit 75 volunteers and divide them into 25 groups, with 3 people in each group. Measure the activity of human sweat glands on their palms and use the starch-iodine method to stain the active sweat pores. Soak absorbent cotton in an aqueous solution of 50% plant antiperspirant sunscreen repair composition and place it on the left palm, and also soak absorbent cotton in an equal amount of water and place it on the right palm. Keep it at 25°C for 30 minutes. Then remove the absorbent cotton and dry the palm surface. Use a 3% iodine-alcohol solution and a 10% starch-castor oil solution to stain the palms. The volunteers soak their feet in hot water at 42°C for 30 minutes to induce sweating. Observe and calculate the number of active sweat pores within 1 cm 2 The antiperspirant effect is 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 takes the average value of each group; the obtained data is shown in Table 3.

[0132] Table 3

[0133]

[0134]

[0135] As can be seen from Table 3, the plant antiperspirant sunscreen repair composition provided by the present invention has good UV 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 reduction rate of active sweat pores is above 30.0%;

[0136] As can be seen from Examples 1 - 5 and Comparative Examples 1 - 5, the mass parts of the components have an obvious impact on the performance of the product. When the mass of the components in Comparative Examples 1 - 5 is not within the range given by the present invention, the comprehensive performance of the obtained product is poor;

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

[0138] Effect Example 2

[0139] This invention explores the performance of sunscreen lotions prepared from Application Examples 1 - 13, Comparative Application Examples 1 - 13, and Blank Application Examples, including the following aspects:

[0140] 1. SPF Value Test

[0141] The test is conducted in accordance with the requirements of the "Technical Specifications for Cosmetics Safety" (2015 Edition). 135 volunteers aged 32 to 60 are selected and divided into 27 groups of 5 people each. The minimum erythema dose (MED) of the subjects' skin to ultraviolet irradiation is predicted, and the ultraviolet irradiation dose is adjusted. A normal skin area not less than 30 cm 2 is selected on the back of the subject, and the test item to be detected is evenly applied to the above area at a dosage of (2.00 ± 0.05) mg / cm 2 . Then, the irradiation dose is selected according to the specification requirements, and irradiation is carried out in three cases: ① The subject's skin is not coated with the test item; ② A reference product is coated (SPF value 16.1 ± 2.4, prepared according to the high - SPF standard product P2 standard formula in the "Technical Specifications for Cosmetics Safety" 2015 Edition); ③ The test item is coated. After 24 hours, the experimental results are observed, and the MED values in the three cases are recorded respectively.

[0142] SPF Value Calculation Method: The SPF value of the test item or blank control for protecting a single subject is expressed by the following formula:

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

[0144] Calculate the arithmetic mean of the SPF values of the test item for protecting all subjects, and retain one decimal place for the result; the obtained data is shown in Table 4.

[0145] 2. Sweat - proof Ability Test

[0146] Refer to the SPF value test, with the difference that the subject needs 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 the SPF value before and after exercise. The change rate of the 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 tests were conducted in accordance with the requirements of the "Technical Specifications for Cosmetics Safety" (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 irradiation was predicted, and the ultraviolet irradiation dose was adjusted. On the back of the subjects, a normal skin area not less than 30 cm 2 was selected, and the test substance to be tested was evenly applied to the above area at a dosage of (2.00 ± 0.05) mg / cm 2 . Then, the UVA irradiation dose was selected according to the specifications and irradiation was carried out in three cases: ① The test substance was not applied to the subjects' skin; ② The control product (PFA value 12.7 ± 2.0, prepared according to the S2 formula in the ISO 24442 method) was applied; ③ The test substance was applied. The experimental results were observed 3 hours later, and the MED values in the three cases were recorded respectively.

[0150] Calculation method of PFA value: The PFA value of the test substance or control product for protecting a single subject is expressed by the following formula:

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

[0152] The arithmetic mean of the PFA values of the test substance for protecting all subjects was calculated, and the result was rounded to one decimal place. The obtained results are shown in Table 4.

[0153] 4. Improvement test of TEWL and a* value

[0154] A number of volunteers aged 18 - 45 who had been irradiated with ultraviolet rays to a certain extent were selected. On the day of arrival, no skin care products were applied. After the subjects washed their faces on the same day, they sat quietly in a constant temperature and humidity room at a temperature of 21 ± 1°C and a humidity of 50 ± 10% for 30 min. Facial photographs were taken using Visia 7, and image analysis was performed on the exported red area pictures to obtain the a* value; the initial facial TEWL value was measured using the skin transdermal water loss probe TM Hex (Courage + Khazaka). 135 subjects with an initial facial a* value above 15 were screened and divided into 27 groups with 5 people in each group. When going out every day, the sunscreen products of the application examples were randomly applied to the whole face. TEWL tests and Visia 7 photographs were carried out on the 7th and 14th days, and the improvement of TEWL and a* value of each volunteer on the 0th, 7th, and 14th days was analyzed. The improvement was represented by the improvement rate of each value, and the calculation method was as follows:

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

[0156] Table 4

[0157]

[0158]

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

[0160] As can be seen from Application Examples 1-5 and Comparative Application Examples 1-5, the mass parts of the components in the plant sweat-proof sunscreen repair composition have an obvious influence on the performance of the product. When the mass of the components in Comparative Application Examples 1-5 is not within the range given by the present invention, the comprehensive effect of the obtained product is significantly reduced;

[0161] As can be seen from Application Example 1 and Comparative Application Examples 6-8, the components in the plant sweat-proof sunscreen repair composition are indispensable; as can be seen from Application Example 1 and Comparative Application Examples 9-13, when other similar components are used to replace the components in the present invention, the comprehensive performance of the obtained products shows an obvious downward trend;

[0162] In addition, the comparison diagrams of D0, D7, and D14 days of the sunscreen milk used in Application Example 1 and Blank Application Example are respectively as Figure 1-2 shown, and it can also be clearly seen from Figure 1-2 that excellent effects have been achieved by using the sunscreen milk provided in Application Example 1 of the present invention.

[0163] Effect Example 3

[0164] The present invention explores the usage feeling score of the sunscreen milk prepared in Application Example 1, and specifically includes the following steps:

[0165] Select 30 Asian subjects with sensitive facial skin and recent symptoms of sensitive skin to participate in the test. Distribute sunscreen products to them, and each subject applies an appropriate amount of the product at 2 mg / cm 2 on the face, and conduct a 14-day detection for sensitive skin suitability. Consumers complete a questionnaire survey on the improvement degree of indicators such as usage feeling, discomfort, tolerance, mildness and non-irritation, sweat-proof effect, sunscreen effect, and ease of cleaning; the obtained results are shown in Table 5;

[0166] Table 5

[0167]

[0168]

[0169] It can be seen from Table 5 that the product provided by the present invention has a high consumer usage score, has a mild and non-irritating effect, and is suitable for people with sensitive skin.

[0170] Finally, it should be noted that the above embodiments are intended to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
