Description

Blue light prevention repairing agent and blue light prevention repairing aerosol

Technical Field

The application relates to the field of skin care products, in particular to a blue light prevention repairing agent and a blue light prevention repairing aerosol.

Background

It is known that exposure to sunlight for a long time causes photodamage to the skin, and it is generally known that ultraviolet rays are most harmful to the skin, and therefore, although sunscreen products on the market are complicated at present, the products are mostly harmful to the skin in ultraviolet bands such as UVA and UVB.

In fact, the blue region in visible light is actually very damaging to the skin. Blue light is the wavelength with the shortest wavelength and the highest energy in the visible spectrum, and the penetrating power of the blue light is even higher than that of ultraviolet rays, so that the blue light can also generate damage similar to the ultraviolet rays on skin. Current research shows that blue light can penetrate skin tissue and has phototoxicity, and can affect growth, metabolism, DNA damage of epithelial cells and even cause cell dysfunction and induce apoptosis. It has also been found that blue light exposure has a relationship with photoaging of the skin, age-related diseases and tumorigenesis.

In addition, compared to sunlight, most consumers now have access to various artificial light sources and display devices, such as LED lamps, computer monitors, mobile phones, etc., which can generate a large amount of blue light, causing severe damage to the skin. At present, for part of the consumer population, the effect of blue light on skin is even much greater than that of ultraviolet light because of less exposure to sunlight over a long period of time to various types of electronic devices that produce blue light.

With the understanding of people about the blue light hazard, the protection requirement for blue light is inevitably increased explosively, and on the basis, blue light resistant cosmetics are also inevitably another hot point of light protection cosmetics. At present, most of the main active ingredients of the blue light resistant products are chemically synthesized, and although the chemically synthesized active ingredients have good blue light resistant performance, the chemically synthesized active ingredients often have certain sensitization and are not suitable for sensitive skin.

Disclosure of Invention

In order to improve the problem that the sensitization of the existing common blue-light-proof cosmetics is stronger, the application provides a blue-light-proof repairing agent and a blue-light-proof repairing aerosol.

The application provides a prevent blue light repairing agent and prevent blue light repair aerosol adopts following technical scheme:

in a first aspect, the application provides a blue light-proof repairing agent, which adopts the following technical scheme:

the blue-light-proof repairing agent comprises the following raw materials in parts by mass:

the photorepair component at least comprises camellia extract, clover extract and calendula extract.

By adopting the technical scheme, the alfalfa flower extract has specific absorption under the blue light wavelength of 400 nm and 500nm, and can prevent the irradiation of the blue light in sunlight, display equipment, LED lamps and the like to the skin. The alfalfa flower extract has good antioxidation, and free radicals are eliminated through an ROS signal channel, so that skin injury is repaired.

The main active ingredients in the calendula extract are carotenoid compounds, polysaccharides, flavonol and terpenoids and the like, wherein the flavonol can quench free radicals and filter harmful blue light, so that the damage of the blue light to the skin is reduced.

The camellia extract has anti-allergic and anti-inflammatory effects, and can repair the damage that skin receives the blue light, therefore, the camellia extract is synergistic with alfalfa flower extract, calendula extract, reduces the damage of blue light to skin through straining the blue light on the one hand, repairs the damage that skin received the blue light on the one hand, thereby reduces the damage of blue light to skin.

Because the photorepair components are all plant-derived extracts, the sensitization is lower, and for example, the camellia extract has even further anti-sensitization and anti-inflammation and skin repair effects, so that the sensitization of some inevitable additives in the system can be reduced.

Optionally, the humectant is one or more of 1, 3-butanediol, glycerol, betaine, hyaluronic acid, and collagen.

By adopting the technical scheme, the moisture content of the skin has great influence on the state of the skin, and a large amount of moisture is needed no matter the damage of the blue light to the skin is prevented or the damage of the skin after the blue light irradiation is repaired, so that the reasonable compounding of the humectant has important influence on the blue light prevention effect of the system.

Optionally, the humectant is 1, 3-butanediol, glycerin, betaine and hyaluronic acid according to a mass ratio of (1-5): (1-5): (1-3): (1-3).

By adopting the technical scheme, the 1, 3-butanediol, the glycerol and the betaine are common moisturizing components in cosmetics, and the hyaluronic acid is further added because the hyaluronic acid is an important component of the skin and the skin has a good absorption effect on the hyaluronic acid, so that the absorption rate of the whole moisturizing agent can be improved and the moisturizing effect of the skin can be improved. However, the addition amount of hyaluronic acid is not too large, and the viscosity of hyaluronic acid is high, so that the viscosity of the whole system is too high after the hyaluronic acid is excessively added, and the hyaluronic acid cannot be prepared into a spray formulation. And the inventor finds that the mixture with specific composition and proportion can obtain obviously better moisturizing effect as the moisturizing agent.

Optionally, the antibacterial agent is one or more of coconut oil, panthenol, a herba lysimachiae extract and a honeysuckle extract.

By adopting the technical scheme, compared with the common antibacterial preservatives such as butyl p-hydroxybenzoate, sorbic acid, benzoic acid, p-hydroxybenzoate and the like, the coconut oil extract, the desmodium extract and the honeysuckle extract are plant source components, so that the components are safer, and the allergenicity is lower.

Coconut oil is rich in active substances such as lauric acid, palmitic acid, caprylic acid and the like. Caprylic acid, lauric acid and the like have certain antibacterial properties, wherein the lauric acid is a safe and efficient broad-spectrum bactericide and can inhibit HIV (human immunodeficiency virus), cytomegalovirus, herpes virus, cold virus and a large number of bacteria and protozoa. The antibacterial effect is not affected by pH, and compared with sorbic acid, benzoic acid and p-hydroxybenzoate, the antibacterial effect is better and safer. However, lauric acid easily breaks the sebum membrane and lowers the moisture-retaining and water-retaining ability of the skin, and therefore, the amount of coconut oil added needs to be strictly controlled.

Panthenol, also known as previtamin B5, can stimulate epidermal cells, promote growth, and permeate skin stratum corneum, has the effect of protecting skin barrier, and can resist external stimulation after being combined with amino acids, thereby greatly reducing skin sensitivity. In addition, panthenol can promote wound healing, and has anti-inflammatory and antibacterial effects.

The herba lysimachiae extract has a wider antibacterial spectrum and a better antibacterial effect, and the minimum antibacterial concentration of the herba lysimachiae extract is smaller, which indicates that the herba lysimachiae extract can obtain a better antibacterial effect under a smaller concentration.

The flos Lonicerae extract contains chlorogenic acid and ketone compounds, such as isochlorogenic acid, neochlorogenic acid, and flavonoids. Chlorogenic acid and flavonoids have been proved to have remarkable bacteriostatic action, and the honeysuckle extract is used as an antibacterial agent, so that the sensitization is low and the safety is higher.

Optionally, the antibacterial agent is coconut oil, panthenol and a lysimachia christinae hance extract according to a mass ratio of 1: (0.5-1): (2-3).

By adopting the technical scheme, the inventor finds that the types and the proportion of the antibacterial agents need to be strictly controlled, and antagonism exists even among some plant-derived antibacterial agents, for example, if the elsholtzia extract and the lysimachia christinae hance extract are used in a compounding way, the synergistic interaction effect cannot be achieved, and the minimum antibacterial concentration is even improved, which shows that the antibacterial effects of the elsholtzia extract and the lysimachia christinae hance extract have antagonism.

Specifically, the inventors found that, compared to the use of coconut oil, panthenol or herba lysimachiae extract alone as the antibacterial agent, the ratio of coconut oil, panthenol and herba lysimachiae extract in terms of mass ratio is 1: (0.5-1): when the mixture in the step (2-3) is used as an antibacterial agent, the antibacterial effect of the system is obviously improved, which shows that the coconut oil and the lysimachia christinae hance have a synergistic antibacterial effect under a specific compounding ratio.

In addition, even if the addition amount of coconut oil is strictly controlled, the addition of coconut oil can damage the sebum membrane of the skin, thereby reducing the moisture retention and water locking capacity of the skin. After the coconut oil and the panthenol are compounded for use, the panthenol can protect the skin barrier and reduce the influence of the coconut oil on the skin, so that the sensitization of the skin is reduced on the basis that the system has a good antibacterial effect.

Optionally, the photorepair component further comprises one or more of p-xylylene dicamphor sulfonic acid, rutin, tetrandra root extract, purslane extract, gentian extract, chamomile extract, opuntia ficus-indica stem extract, dandelion extract, dendrobium nobile extract, peach resin extract, oat kernel oil, sage extract, kava root extract, and gardenia flower extract.

By adopting the technical scheme, the inventor finds that the display parts of various electronic equipment can emit ultraviolet rays which are divided into UVA, UVB and UVC, wherein the UVA with the longest wavelength easily penetrates deep into the skin deep layer to damage the dermis layer of the skin, so that the skin is aged, and therefore, in order to reduce the damage of the ultraviolet rays to the skin, various plant extracts can be compounded to improve the photoprotective effect of the system.

Generally, the photorepair component can be selected according to actual production requirements, however, the inventors have unexpectedly found that when the photorepair component comprises p-xylylene dicamphor sulfonic acid, the overall effect of the system is better.

Firstly, p-xylylene dicamphor sulfonic acid, also called Maifanin filtering ring, is one of the most effective UVA sunscreen components at present, and the maximum protective wave band can reach 344nm, so that the protective film has good protective effect on the UVA wave band with the greatest damage to the skin in ultraviolet rays.

And secondly, the antibacterial and anticorrosive performance of the blue light-proof repairing agent is obviously improved, probably because glycerin in the system reacts with lauric acid in coconut oil to generate an esterified substance under the catalysis of p-xylylene dicamphor sulfonic acid, and the antibacterial performance of the esterified substance is superior to that of the lauric acid, so that the finally obtained blue light-proof repairing agent has remarkably better antibacterial and anticorrosive performance.

Furthermore, the dispersibility and the dispersion stability of the blue light prevention repairing agent are also obviously improved, probably because the p-xylylene dicamphor sulfonic acid can also catalyze the reaction of 1, 3-butanediol in a system and caprylic acid in coconut oil to form 1, 3-butanediol caprylate, and the ester compound has good dissolving capacity and dispersing capacity for common UV (ultraviolet) sun-screening agents, so that the dispersion stability of each component in the system can be greatly improved, and the ester compound has a difficult sensitive effect on sensitive muscles, and is particularly suitable for products such as sun-screening, photo-repairing and the like.

In a second aspect, the present application provides a blue light prevention repair aerosol, which adopts the following technical scheme:

Staphylococcus aureus (Staphylococcus aureus) [ CMCC (B)26003]Escherichia coli (CMCC (B)44102]Pseudomonas aeruginosa [ CMCC (B)10104]Candida albicans (CMCC (F)) 98001]And Aspergillus niger (CMCC (F)98003]The strains in 5 were used as test strains, and the preparation of the suspensions was carried out according to the protocol ISO 11930:2019, and the number of bacteria contained in the suspensions was about 1X 10⁸CFU/mL。

Taking the blue-light-proof repairing agent compounded in each embodiment or comparative example as a sample, putting the sample into a sterilization container, adding bacterial suspension with the volume fraction of 1%, storing the sample at 25 ℃ in a dark place for 24 hours, taking 1mL of mixed solution, diluting the mixed solution, culturing the diluted mixed solution in an agar culture medium for 48 hours, and measuring the total number of bacterial colonies at the culture temperature of 36 ℃ to calculate the sterilization rate.

The above performance test data are shown as the following table:

conclusion

By comparing the data of example 1 and comparative example 1, it can be shown that compared with the conventional commercially available photorepair component on the market at present, the plant source extract in the application is compounded and used as the photorepair agent, so that the allergenicity of the system can be reduced on the basis of ensuring the blue light prevention repairing effect. The allergen in example 1 should be the antimicrobial agent butyl paraben, which is a highly irritating compound, although it has good antimicrobial preservative effect.

Comparing the data of examples 1 and 4 to 8, it can be concluded that the specific use of a mixture of 1, 3-butanediol, glycerol, betaine, and hyaluronic acid in a certain mass ratio as a humectant can significantly reduce the sensitization of the system, probably because the specific humectant can achieve a better moisturizing effect, thereby enabling the anti-blueing and photorepair effects of the system to take a better effect.

It can be concluded from the comparison of the data of examples 8-10 that even if butyl paraben is replaced by a mixture of extracts of plant origin as an antibacterial agent, the sensitization of the system is still high, probably because, although the amount of added coconut oil in the system has been strictly controlled, the nature of coconut oil itself determines that coconut oil destroys the sebum membrane on the skin surface, thereby causing a decrease in the ability of the skin to moisturize and lock water, etc., and the skin tends to become more sensitive.

It can be seen from the comparison of the data of examples 8 and 11 to 13 that the sensitization of the system can be greatly reduced by further adding panthenol to coconut oil, probably because panthenol can play a role in repairing the skin and can also permeate the horny layer of the skin and combine with amino acid to resist external stimulation, thereby greatly improving the anti-sensitization of the skin itself. Therefore, when coconut oil is added to the system, a certain amount of panthenol is added simultaneously, so that the sensitization of the system can be reduced.

It can be seen from comparing the data of examples 13-16 that the blue light protection effect of the system is not greatly affected by the addition of p-xylylene dicamphor sulfonic acid to the photorepair component (the anti-uv effect of the system is not detected because the protective effect of p-xylylene dicamphor sulfonic acid to UVA is known), and that the sensitization to p-xylylene dicamphor sulfonic acid is also low. But after the p-xylylene dicamphor sulfonic acid is added, the stability and the antibacterial and antiseptic properties of the system are obviously improved. This demonstrates the synergistic antimicrobial and stability enhancing effect of p-xylylene dicamphor sulfonic acid with certain materials in the system.

Comparing the effects of example 14 and example 17, it can be seen that, based on the addition of p-xylylene dicamphor sulfonic acid to the photorepair component, the antimicrobial and antiseptic effects and stability of the system are significantly reduced if coconut oil is not added to the antimicrobial agent. This demonstrates the synergistic antibacterial and stability enhancing effect between terephthalylidenedicamphor sulfonic acid and coconut oil.

Comparing the effects of example 14 and example 18, it can be seen that, on the basis of adding p-xylylene dicamphor sulfonic acid to the photo-repair component and adding coconut oil to the antimicrobial agent, if glycerin is not added to the system, the stability of the system is not changed significantly, but the antimicrobial and antiseptic properties of the system are reduced significantly. This is probably due to the synergistic antimicrobial preservative effect between para-xylylene dicamphor sulfonic acid coco and glycerin.

Comparing the effects of example 14 and example 19, it can be seen that, on the basis of adding p-xylylene dicamphor sulfonic acid to the photo-repair component and adding coconut oil to the antimicrobial agent, if 1, 3-butanediol is not added to the system, the antimicrobial and antiseptic properties of the system are not changed significantly, but the stability of the system is significantly reduced. This is probably due to the synergistic stability-enhancing effect between coco p-xylylenedicamphor sulfonate and 1, 3-butanediol.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
