Embodiment 1

[0031] The preparation of embodiment 1 camphor leaf extract

[0032] Take the fresh purebred Cinnamomum camphora leaves, remove impurities and wash them, dry them at room temperature, cut them into pieces, steam them for 15 seconds at a steam pressure of 0.2MPa and a temperature of 105°C, and cool them down; Soak in 90% ethanol for 3 hours, ultrasonically extract for 45 minutes at a temperature of 40°C, filter, distill the filtrate under reduced pressure to recover ethanol, concentrate under reduced pressure to a relative density of 1.20 at 60°C, and obtain a cinnamon camphor leaf extract.

Embodiment 2

[0033] The preparation of embodiment 2 chlorophyll composite liposomes

[0034] The chlorophyll composite liposome described in this example comprises the following components in parts by weight: 70 parts of lecithin, 14 parts of cholesterol, 21 parts of Tween-80, 6 parts of chlorophyll and 8 parts of camphor leaf extract.

[0035] Preparation methods include:

[0036] S1: Take lecithin, cholesterol, Tween-80, chlorophyll and cinnamon camphor leaf extract, add absolute ethanol at a solid-to-liquid ratio of 18 mg / mL, stir to dissolve fully, and then at a temperature of 40°C under vacuum conditions, Ethanol was removed by rotary evaporation to form a thin film;

[0037] S2: Add a PBS solution with a pH of 7.5 and a concentration of 0.05 mol / L according to a solid-to-liquid ratio of 0.08 g / mL, and rotate at normal pressure for 45 minutes to wash the membrane to obtain a liposome solution;

[0038] S3: Take the liposome solution, and process it four times with a dynamic high-pre...

[0039] The preparation of embodiment 3 chlorophyll composite liposomes

[0040] The chlorophyll composite liposome in this example comprises the following components in parts by weight: 60 parts of lecithin, 12 parts of cholesterol, 18 parts of Tween-80, 8 parts of chlorophyll and 10 parts of camphor leaf extract.

[0041] Preparation:

[0042] S1: Take lecithin, cholesterol, Tween-80, chlorophyll and Cinnamomum camphora leaf extract, add absolute ethanol at a solid-to-liquid ratio of 20mg / mL, stir to dissolve fully, and then at a temperature of 40°C under vacuum conditions, Ethanol was removed by rotary evaporation to form a thin film;

[0043] S2: According to the solid-to-liquid ratio of 0.1g / mL, add a pH of 7.4 and a concentration of 0.04mol / LPBS solution, and rotate at normal pressure for 50 minutes to wash the membrane to obtain a liposome solution;

[0044] S3: Take the liposome solution, and use a dynamic high-pressure microfluidizer to process it 5 times under the c...

The chlorophyll-containing skincare product capable of resisting sunburn and repairing after sunburning is prepared from chlorophyll compound liposome, hydrogenated jojoba oil, amygdalus pedunculata oil, squalane, cyclopentasiloxane, cetostearyl alcohol, PEG-100 stearate, tocopheryl acetate, bisabolol, butanediol, beta-glucan, sodium hyaluronate, carbopol, mycose, cetearyl glucoside, vitamin C ethyl ether, moringa oleifera leaf extract, triethanolamine, preservatives, essence and water. The chlorophyll-containing skincare product is stable in property, high in safety and high in usage comfort, is capable of effectively resisting ultraviolet rays of different wavebands, also has a good function of resisting photo-aging, and is also capable of preventing symptoms such as skin aging, freckles and desquamation and the like caused by sunburn and accelerating the repairing of the skin after sunburning.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and relates to a chlorophyll sunscreen and after-sun repair skin care product. Background technique [0002] As people's awareness of the importance and necessity of UV protection continues to deepen, the demand for sunscreen cosmetics market is also increasing, and safe, efficient, and broad-spectrum sunscreen products have gradually become the focus of attention. Sunscreens are the key ingredients in sunscreen cosmetics that play a role in sun protection. Currently, sunscreens on the market are mainly divided into physical UV shielding agents and chemical UV absorbers. Physical sunscreens are non-irritating to the skin, but have poor absorbency, transparency, and air permeability. They are used to prepare sunscreen cosmetics, and the comfort of the product needs to be improved. Chemical sunscreens are irritating to the skin, and may cause allergic and irritating reactions on sensitive skin. ...
