Description

Plant sun-proof synergistic agent, preparation method and application Technical Field The invention relates to the field of cosmetics, in particular to a plant sun-proof synergistic agent, a preparation method and application. Background Cosmetic sunscreens are core efficacy components of products such as sunscreens, sun-block emulsions, etc., intended to protect the skin from ultraviolet (UVA and UVB) rays, and are classified into chemical sunscreens and plant sunscreens. The chemical sunscreens act by "absorbing and converting" ultraviolet light, the molecular structure of such components being capable of absorbing ultraviolet light of a specific wavelength (mainly UVA and/or UVB), after absorbing energy, the molecules change from a ground state to an excited state and then release the energy in the form of lower thermal energy, thereby avoiding direct damage to skin cells by the ultraviolet light. However, some chemical components (such as benzophenone-3 and octocrylene) may have a certain irritation or sensitization risk to sensitive muscles, and few components (such as avobenzone) have poor light stability and need to be matched with other stabilizers, and in addition, some components (such as ethylhexyl methoxycinnamate) are researched and considered to have potential influence on aquatic ecosystems such as coral reefs. Unlike chemical sunscreens, plant sunscreens not only block ultraviolet rays, but also exert anti-inflammatory repair effects on the skin, thereby reducing erythema generation and achieving a sunscreening effect. In addition, the source of plant sunscreens is generally safe and reliable, and the probability of causing adverse reactions is lower, so that the plant sunscreens are more accepted by consumers. However, plant sunscreens have certain limitations such as limited ultraviolet absorption capacity, incomplete coverage of the band, and the like. Research on solutions to the limitations of the method is of great importance. Disclosure of Invention Aiming at the technical problems, the invention provides a plant sun-proof synergistic agent, a preparation method and application. The plant sun-proof synergistic agent consists of a baical skullcap root extract, a tea extract and a szechuan lovage rhizome extract. Wherein the Scutellariae radix extract is obtained by extracting with water solution containing butanediol and sodium metabisulfite as extraction solvent. The concentration of butanediol and sodium metabisulfite in the aqueous solution is 12-30wt% and 0.1-0.8wt%, respectively. The rhizoma Ligustici Chuanxiong extract is obtained by extracting with water solution containing butanediol and ethanol as extraction solvent. The concentration of butanediol and ethanol in the aqueous solution is 15-30wt% and 15-35wt%, respectively. The extraction temperature is 45-60deg.C when the above Scutellariae radix extract and rhizoma Ligustici Chuanxiong extract are extracted. And the extraction time of both is 2-6h. The tea extract is obtained by extracting with an aqueous solution containing butylene glycol and sodium metabisulfite as an extraction solvent. In the aqueous solution, the weight ratio of water to butanediol to sodium metabisulfite is (75-85): 18-23): 0.3-0.8. The extraction temperature and time are respectively 50-60 ℃ and 1.5-2.5h. The three extracts can also comprise post-treatment steps after extraction, wherein the post-treatment can comprise at least one of the processes of filtering, adding preservative, decoloring and the like. For example, after extraction of scutellaria baicalensis using the extraction solvent, the method may further comprise post-treatment by filtration with a microporous membrane and addition of a preservative. After extracting Ligusticum chuanxiong with extraction solvent, the method may further comprise post-treatment of filtration with microporous membrane. After extraction of tea leaves using the extraction solvent, post-treatments of decolorization and microfiltration may also be included. The Scutellariae radix extract (baicalin and baicalein as main active ingredients) is commonly used as antiinflammatory and antioxidant component in sun-screening products. The action mechanism comprises absorbing ultraviolet rays (especially UVA/UVB wave band), scavenging free radicals (reducing oxidative stress injury), inhibiting tyrosinase activity (indirectly reducing melanin generation), and relieving inflammation and pain (relieving skin redness and swelling after sunburn). The rhizoma Ligustici Chuanxiong extract (mainly contains ligustrazine and ferulic acid) has effects of inhibiting melanin formation (by inhibiting tyrosinase activity) and resisting oxidation (scavenging free radicals). In the sun-screening product, the sun-screening agent not only can enhance sun-screening effect, but also can pre-screen pigmentation (such as color spots and darkness) after sun screening. Tea extract (mainly comprising tea polyphenols and catechin) is commonly used
