Description

Technical Field

[0001] The present invention relates to the technical field of sunscreen agents, and specifically relates to a sunscreen agent composition with an anti-aging effect. Background Art

[0002] Sun protection refers to some methods and measures taken to prevent the skin from being sunburned or tanned, mainly to defend against the damage of ultraviolet rays (UV) to the skin.

[0003] Ultraviolet rays can penetrate the epidermis of the skin and reach the dermis. It is the main cause of skin tanning because it can stimulate melanocytes in the skin to produce melanin. Long-term exposure to ultraviolet rays will cause premature skin aging, resulting in wrinkles, sagging and other phenomena. This is because ultraviolet rays will damage collagen and elastic fibers in the skin, just like destroying the supporting structure of a building, making the skin lose elasticity and firmness.

[0004] Ultraviolet rays are also an important inducer of skin cancer. Therefore, by using sunscreen products and taking sun protection measures, the dose of skin exposure to ultraviolet rays can be effectively reduced, thereby reducing the risk of skin cancer. Especially for those with fair skin who are prone to sunburn, sun protection is particularly important.

[0005] Chemical sunscreen agents are substances that achieve sun protection by absorbing ultraviolet rays. Common ones include p-aminobenzoic acid and its esters, o-aminobenzoic acid esters, methoxycinnamic acid esters, etc. Although they can effectively protect against the sun, they also have the following drawbacks: strong skin irritation; easy to cause allergic reactions: some people may experience allergic symptoms such as skin redness, itching, and rashes after using chemical sunscreen agents. For example, p-aminobenzoic acid (PABA) was once a commonly used chemical sunscreen agent and was prone to cause skin allergies, resulting in contact dermatitis. It can irritate the skin and mucous membranes: the skin around the eyes is relatively sensitive. If a chemical sunscreen agent accidentally gets into the eyes, it will cause eye irritation, redness and other discomforts. Moreover, if it is used on the lips, it may be inadvertently licked and enter the human body, causing irritation to the oral mucosa and the like.

[0006] Based on this, the present invention provides a sunscreen agent composition with an anti-aging effect to solve the corresponding problems. Summary of the Invention

[0007] In view of the problems in the prior art, the present invention provides a sunscreen agent composition with an anti-aging effect.

[0018] The concentration of the hydrochloric acid solution is 1 mol / L;

[0019] Keep the acidic Rosa roxburghii fruit pulp in a water bath at 10 °C, then carry out high - speed centrifugation for 15 min, filter, remove the filtrate, obtain the filter residue, wash it to neutral, freeze - dry, crush, and pass through a 60 - mesh sieve to obtain the preliminary powder;

[0020] The speed of the high - speed centrifugation is 8000 r / min;

[0021] Mix the above - obtained preliminary powder and ethanol solution evenly to obtain a preliminary slurry;

[0022] The mass fraction of the ethanol solution is 80%;

[0023] Keep the obtained preliminary slurry under high - pressure impregnation for 30 min, then carry out high - speed centrifugation for 15 min, filter, remove the filter residue, and retain the filtrate;

[0024] The speed of the high - speed centrifugation is 6500 r / min;

[0025] Carry out spray drying on the obtained filtrate to obtain the extract of Rosa roxburghii fruit.

[0026] As a further technical solution: the rosa roxburghii fruit and water are mixed and pulped at a material-liquid ratio of 1:10, the pulping speed is 3500 r / min, and the pulping time is 30 min;

[0027] The mass ratio of the preliminary powder and the ethanol solution is 1:10.

[0028] As a further technical solution: the high-pressure impregnation pressure is 42 - 45 MPa, and the impregnation temperature is 50 °C.

[0029] As a further technical solution: the preparation method of the zanthoxylum bungeanum fruit extract is as follows:

[0030] The zanthoxylum bungeanum fruit is crushed, then mixed and stirred with an ethanol solution with a mass fraction of 75% at a material-liquid ratio of 1:8 for 4 hours, then centrifuged at a speed of 5000 r / min for 20 min, filtered, and the filtrate is retained. The filtrate is spray-dried to obtain the zanthoxylum bungeanum fruit extract;

[0031] The preparation method of the cherry blossom extract is as follows:

[0032] The cherry blossom is crushed, then mixed and stirred with an ethanol solution with a mass fraction of 85% at a material-liquid ratio of 1:5 for 3.5 hours, then centrifuged at a speed of 5500 r / min for 15 min, filtered, and the filtrate is retained. The filtrate is spray-dried to obtain the cherry blossom extract.

[0036] As a further technical solution: the emollient is glycerol;

[0037] The water-locking factor is butanediol.

[0038] The beneficial effects of the present invention:

[0039] The sunscreen composition prepared by the present invention can absorb the energy of ultraviolet rays, convert it into heat energy or other harmless energy forms and release it, thereby reducing the damage of ultraviolet rays to the skin. After absorbing the energy of ultraviolet rays, the energy is released in the form of heat energy through molecular vibration and other means to prevent ultraviolet rays from penetrating the skin.

[0040] Excessive use of chemical sunscreen agents may cause irritation to some sensitive skin because a portion of their chemical components may be absorbed by the skin. Therefore, in the present invention, chemical components are combined with biological components, with the biological components as the main part, and some natural bioactive substances are used in combination to achieve the effect of resisting ultraviolet rays, which can reduce the damage of skin free radicals caused by ultraviolet rays.

[0041] Since the biological components used in the present invention are relatively mild and safe and can be suitable for use on sensitive skin, they are derived from natural substances and meet the current consumers' demand for natural and green cosmetics.

[0042] By the way of combining chemical components and biological components to enhance the sunscreen effect, the sunscreen bands can be complementary:

[0043] Chemical components can provide a relatively broad spectrum of UVA and UVB protection, while biological component sunscreen agents can provide supplementary protection in specific bands. When chemical components may have some weak links in absorbing certain UVA bands, some components in biological components can enhance the overall UVA protection effect by reflecting and scattering ultraviolet rays in these bands.

[0044] Ultraviolet irradiation of the skin will generate a large amount of free radicals. Chemical components mainly absorb the energy of ultraviolet rays, while the antioxidant components in biological components can scavenge these free radicals. They work together, on the one hand, reducing the penetration of ultraviolet rays, and on the other hand, reducing the damage of the already generated free radicals to the skin, thereby enhancing the comprehensive sunscreen effect.

[0045] The sunscreen agent composition prepared by the present invention not only has excellent sunscreen effect, but also has excellent anti-aging effect. Through its high antioxidant effect and free radical scavenging ability, it can provide better protection for the skin. The sunscreen agent composition of the present invention can improve the skin feel, increase the SPF value, and a small amount of sunscreen agent dosage can achieve a significant sunscreen effect.

[0162] Among them, the test method for the ability to scavenge hydroxyl radicals is as follows: In a 96-well plate, 10 μL of a salicylic acid solution with a concentration of 1.24 mg / mL, 10 μL of a ferrous sulfate solution with a concentration of 2.5 mg / mL, and 130 μL of ultrapure water are added in sequence. Then, 40 μL of the compositions of the examples and comparative examples are added respectively. Finally, 10 μL of H2O2 with a concentration of 0.03% is added to initiate the reaction. After incubating at 37 °C for 15 min, a test sample is obtained, and the absorbance value of the test sample at a wavelength of 510 nm is measured. The absorbance value at a wavelength of 510 nm without adding the H2O2 solution is used as a control, and a matrix blank control (pure water) is set, and the hydroxyl radical scavenging rate is calculated.

[0163] The calculation formula for the hydroxyl radical scavenging rate is: ((Ablank - Acontrol) - (Asample - Acontrol)) / (Ablank - - Acontrol) × 100%;

[0164] Among them, Ablank represents the absorbance value of the matrix blank control at a wavelength of 510 nm, Acontrol represents the absorbance value without adding the hydrogen peroxide solution at a wavelength of 510 nm, and Asample represents the absorbance value of the test sample at a wavelength of 510 nm.
