Problems solved by technology

[0004] Tyrosinase, also known as phenol oxidase, polyphenol oxidase, catechol oxidase, is a copper-containing metal oxidase with a complex structure. Tyrosinase is the key enzyme for the synthesis of melanin, although melanin can effectively absorb Ultraviolet rays protect the skin from ultraviolet rays, but its abnormal excessive expression in the body can cause many pigmentation skin diseases in the human body, such as freckles, chloasma, age spots, etc. Among the existing whitening skin care products, its effective Most of the whitening ingredients are extracted from plants. The process is complicated, the extraction rate is low, and the whitening mechanism is not clear, resulting in insignificant whitening effect. After stopping use, the skin whitening is difficult to maintain

preparation example Construction

[0033] The preparation method of whitening and blackening agent is:

[0034]

[0035] Add 10mmol of 5-p-hydroxybenzyl-2,4-thiazolidinedione with the structure of formula 1 into the reaction flask, add 100ml of ethanol to dissolve, then add 30mmol of bisabolol succinic acid with the structure of formula 2, and wait for the After the alcohol succinic acid 2 is dissolved, add 30mmol of condensing agent, raise the temperature to 70°C, and stir for 4 hours. After the reaction is completed, filter the reaction solution to remove insoluble matter. After the filtrate is concentrated under reduced pressure, add 100mL of ethyl acetate to dissolve , followed by washing with saturated sodium bicarbonate solution (100mL*3), 100mL saturated sodium chloride solution, discarding the water phase, adding 10g of anhydrous sodium sulfate to the organic phase for dehydration and drying for 5h, filtering, concentrating under reduced pressure, petroleum ether-ethyl acetate The ester was recrystalli...

Abstract

The invention discloses a skin-whitening cosmetica whitening skin care product containing algae active extracts. The skin-whitening cosmetics iswhitening skin care product is prepared from the following raw materials in percentage by mass: 2 to 5 percent of hyaluronic acid, 0.5 to 1 percent of lecithin, 4 to 8 percent of glycerol, 1 to 5 percent of cetostearyl alcohol, 1 to 5.5 percent of glycerylstearate, 0.5 to 3 percent of polydimethylsiloxane, 0.5 to 1.5 percent of algal active extracts, 0.2 to 0.8 percent of whitening and anti-blackening agents, 2 to 6 percent of natural whitening grease, 0.5 to 1 percent of VC, 0.5 to 1 percent of VE, 0.1 to 0.35 percent of pH regulators, 1 to 5 percent of propanediol and the balance of deionized water. The raw material ingredients are scientifically proportioned; the activity of tyrosinase is inhibited internally in an inner aspect; the problem of melanin generation is fundamentally solved; in an outer aspectexternally, the active free radicalsare cleared through irideae extracts; the immunologic function of the skin is improved, so that the durable and continuous skin whitening effects can be achieved.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, in particular to a whitening skin care product containing active algae extracts. Background technique [0002] In today's society, with the rapid development of production and economy, air pollution is also becoming more and more serious. Electromagnetic radiation, automobile exhaust and dust in the air have all affected human health. PM 2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs. PM 2.5 contains heavy metals, nitrides, sulfides and other toxic substances. When our skin is exposed to the air, these toxic substances will enter the pores, causing clogged pores and blackheads, which eventually lead to dull skin and poor skin metabolism. And accelerate skin aging. People are also gradually realizing that adding a protective barrier to the skin against the external environment is a...
