Embodiment Construction

[0025] The present invention applies the protective mechanism of mesocarp in nature to skin care, and prepares cosmetics with whitening and anti-aging effects. The cosmetics use plant peels as main raw materials, extract natural water-soluble active substances from them, and have anti-free radical and anti-oxidation properties. and whitening function.

[0026] The present invention extracts the method for water-soluble active substance from peel, comprises the following steps:

[0027] Step 1, crushing the dried peel into powder;

[0028] Step 2, adding the amount of peel powder to distilled water into the extractor according to the weight ratio of 1:2-10, heating and boiling for 30 minutes, after cooling, centrifuge at 4500rpm for 20-40 minutes to remove the precipitate, and take the supernatant to obtain the crude extract of the peel;

[0029] Step 3. Add the crude extract of the pericarp to ethanol with a volume ratio of 1:1 to 10, or add chitin according to the ratio of e...

Abstract

The invention relates to a water-soluble active extract derived from fruit peels, the preparation method and the application thereof. The fruit peel is treated by the steps of drying, pulverization, extraction, flocculation, separation and concentration, to prepare a water-soluble active extract. Then, the extract is added in cosmetic matrixes to allow a cosmetic to have skin-whitening and anti-skin ageing functions. The fruit peel extract is obtained after the screening of tyrosinase-inhibiting, antioxidant and free radical-scavenging activities in the water-soluble extracts of fruit peels such as Citrus peels, and has skin-whitening and anti-skin ageing effects. The water-soluble active extract has the advantages of easily-accessible raw materials, renewable resources and simple preparation method. The obtained extract has good stability and durable effect and serves as cosmetic additives in any stage of cosmetic production, without the risks of solvent residue and microbial contamination.

Description

technical field [0001] The present invention relates to fruit peel extracts and functional cosmetics with whitening and anti-aging activities, in particular, to a water-soluble active substance extracted from fruit peels (containing a large amount of natural fruit flavonoids and fruit polyphenols, including flavonoid glycoside flavonoids and polymethoxy flavonoid flavonoids, etc.), and use this extract to prepare cosmetics with whitening and anti-aging properties. Background technique [0002] The skin is the largest organ of human beings, and its structure is delicate and complex, which is the natural protective barrier of human beings. But with age and the erosion of the environment, its defense function will be destroyed. External stress, such as ultraviolet radiation, and internal stress, such as nervous emotions, will generate a large number of free radicals, which will damage the skin tissue, make the skin rough, produce dark spots, wrinkles, etc., and accelerate the ...
