Description

A kind of tea polyphenol sunscreen and preparation method thereof

technical field

The present invention relates to a cosmetic.

Background technique

The ultraviolet rays radiated from the sun to the ground include UV-B with a wavelength of 290nm-320nm and UV-A with a wavelength of 320nm-400nm. Excessive exposure to these two types of ultraviolet rays will cause sunburn to the skin. Various cells in the dermis release inflammatory mediators such as histamine, 5-hydroxytryptamine, and kinin, which dilates blood vessels and increases permeability in the dermis. Generally manifested as erythema, edema, blisters and pigmentation, desquamation and so on. Therefore, the application of tea polyphenol sunscreen is very necessary.

Generally, tea polyphenol sunscreens on the market are heavy in texture and have added some chemical sunscreens. Applying thick tea polyphenol sunscreen in hot summer will cause discomfort to the skin, and the use of some chemical sunscreens also increases the chance of skin allergies and even causes skin symptoms.

Specifically, the surfactant is preferably one or more of cocamidopropyl hydroxysultaine, cocoyl monoethanolamide sulfosuccinic monoester disodium, cocamidopropyl betaine Mixtures; more preferably cocamidopropyl betaine.

The preparation method of tea polyphenol sunscreen of the present invention comprises the following steps:

(1). Preparation of the water phase: under stirring, dissolve the hyaluronic acid and the surfactant in the formula amount in deionized water, and heat to 60-80°C;

(2). Preparation of the oil phase: under stirring, the cetearyl alcohol, glycerin, cetyl alcohol, pearl powder, titanium dioxide, 3,4'-methylbenzylidene camphor, dioctyl carbonate , Bisabolol mixed evenly, heated to 60-80°C;

(3). Preparation of tea polyphenol sunscreen: Slowly add the oil phase prepared in step (2) into the water phase prepared in step (2) under heat preservation, homogenize at 2000-3000r/min for 2-5min, 600 Slowly lower the temperature to 40-50°C under stirring at ~800r/min, add the red amaranth extract, tea polyphenols and Scutellaria baicalensis extract in the prescribed amount, and continue stirring until the material is homogeneous and discharged.

Specifically, the preparation method of the red amaranth extract is as follows: wash the red amaranth and break it into a slurry, and mix the extractant with the red amaranth pulp according to the weight ratio of the extractant and the red amaranth in a ratio of 1:2-3. After the solids are mixed evenly, ultrasonication is performed at 40°C for 20 min to 1 h, and the insoluble matter is filtered off to obtain the red amaranth extract. Wherein the extractant is a 10% ethanol solution by volume.

Specifically, the preparation method of the Scutellaria baicalensis extract is as follows: after the Scutellaria baicalensis is washed and pulverized, according to the weight ratio of deionized water and Scutellaria baicalensis powder is 1:2-3, the scutellaria baicalensis powder is added to water, and extracted by reflux for 2-3 hours, After cooling, the insoluble matter was filtered off to obtain the Scutellaria baicalensis extract.

Anthocyanidin, also known as anthocyanin, is a kind of water-soluble natural pigment widely present in plants in nature. It belongs to flavonoid compounds and is also the main coloring substance in plant petals. Free radicals are produced in the skin under sun exposure, and these free radicals can accelerate skin aging, and anthocyanins can protect the human body from free radical damage and help reduce skin damage caused by sun exposure. Red amaranth contains a large amount of anthocyanins and has good physical stability. Compared with other natural pigments, the anthocyanins in red amaranth (Latin name: Amaranthustricolor) have the characteristics of convenient source of raw materials, low cost, low cost, no pollution, etc., and have good stability and strong oxidation resistance. Extracting from red amaranth is a relatively economical and convenient way to obtain anthocyanins.

Scutellaria baicalensis sweet, light, slightly cold; returns spleen, lung, kidney channel. Promoting dampness and invigorating the spleen; relaxing tendons and eliminating numbness; clearing away heat and expulsion of pus. Mainly edema; beriberi; urinating and leaking; dampness and febrile disease; Scutellaria baicalensis also has a good cosmetic effect on the skin.

Tea polyphenols is the general term for polyphenols in tea, including flavanols, anthocyanins, flavonoids, flavonols, and phenolic acids. It is mainly flavanols (catechins), and catechins account for 60-80%. Active substances such as tea polyphenols have detoxification, anti-radiation and anti-oxidation effects.

The tea polyphenol sunscreen of the present invention mainly uses the physical sunscreen of pearl powder and titanium dioxide, reduces the dosage of chemical sunscreens, and adds a variety of natural sunscreens, has a refreshing texture, and can better avoid the occurrence of allergies. Bisabolol and Scutellaria baicalensis extract have anti-inflammatory and anti-allergic effects on sunburns. Hyaluronic acid has a good moisturizing effect and can replenish skin moisture in time. The tea polyphenol sunscreen of the invention is soft in color, fresh in smell and refreshing, and is suitable for public use.

For better understanding and implementation, the present invention is described in detail below.
