Problems solved by technology

The kojic acid in the ingredients of this invention can achieve whitening effect by blocking the melanin production intermediate, but long-term use will produce cytotoxicity and increase the probability of ovarian cell chromosome aberration
[0004] Various heavy metal compounds such as mercury compounds added to whitening cosmetics in the prior art, due to their strong ability to form complexes, can destroy the formation of epidermal enzymes from the mechanism, thereby inhibiting the formation of melanin and playing a whitening effect. Long-term use of such products is likely to cause cancer; some lead-containing compounds play a visual whitening effect by covering them; some products also use strong oxidants to bleach the skin surface, excessive exfoliation, etc. for whitening. If things go on like this, it will chronically disfigure the skin! Therefore, developing a safe and effective whitening product is one of the key points of cosmetics research and development.

preparation example Construction

[0027] The preparation method of the above-mentioned Cackle Leaf Extract is as follows: take the Cackle Leaf, crush it into coarse powder, add 5 times the amount of deionized water and decoct it for 500 minutes, repeat 3 times, combine the decoction, filter, and concentrate under normal pressure to a paste; take the above paste, add 4 times the amount of 80% ethanol and stir evenly, add sodium hydroxide solution dropwise to adjust the pH to 8, and keep it closed overnight; filter the feed liquid under reduced pressure, and recover the ethanol from the filtrate until it is alcohol-free Taste, refrigerated at 4°C for 24 hours, and then the filtrate was concentrated under normal pressure to obtain the extract of the leaves of Kackler off the coast.

[0028] The preparation method of kudzu root extract is as follows: take fresh kudzu root, wash and dry, crush into coarse particles, decoct the coarse particles with water for 3 hours each time, combine the two filtrates, let stand fo...

Embodiment 1

[0045] Embodiment 1 whitening plant composition (self-made); 95% ethanol (Sinopharm Group Chemical Reagent Co., Ltd.); DPPH (Tokyo Chemical Co., Ltd., analytically pure); AB204-E electronic analytical balance (METTLE TOLEDO); UV- 1600 UV spectrophotometer (METTLE TOLEDO).

[0046] DPPH appears dark purple in absolute ethanol and ethanol-water systems, and has maximum absorption at 517nm and 525nm, respectively. The free radical scavenger can make the purple fade gradually, and the content of DPPH and the scavenging ability of the reactive free radical scavenger to DPPH are measured according to the change of absorbance.

[0047] Accurately weigh 3.00mg of DPPH, dissolve it with 95% ethanol and set the volume to 100ml, the solubility of DPPH is 20mg / L, take 4ml of DPPH standard solution, put it in a test tube, add 1ml of whitening and lightening plant composition solution, and let it stand for 30min , Absorbance A was measured at 517 nm. Determination of DPPH clearance rate a...

Abstract

The invention discloses a skin whitening and spot fading composition and application thereof. The skin whitening and spot fading composition comprises 0.5-2.8 parts of cakile maritima leaf extract, 0.2-1.4 parts of radix puerariae extract and 0.1-1.8 parts of walnut green seedcase extract. The skin whitening and spot fading composition and the application have the advantages that a plurality of components of the skin whitening and spot fading composition are compounded with one another, and efficient skin whitening and spot fading effects can be realized by ways of scavenging free radicals, inhibiting tyrosinase, reducing hyperpigmentation and the like; the skin whitening and spot fading composition can be added into face cream and is high in safety and good in stability, obvious effects can be realized, and skin of users can be moist and white and is high in elasticity if the skin whitening and spot fading composition is used for a long term.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a composition for whitening and lightening spots and its application. Background technique [0002] With the improvement of living standards, people's pursuit of fair and radiant skin is becoming stronger and stronger. The use of whitening cosmetics to achieve bright skin and fair skin has become the common wish of many women. Free radicals attack cells and destroy cell membranes, leading to cell death and changes in cell membranes, so that cells cannot absorb nutrients from the outside, and cannot excrete intracellular metabolic products. Long-term accumulation of melanin leads to various spots such as skin pigmentation and butterfly spots Formation. Whitening and freckle-removing skin care products have always been the focus of research, and products are constantly being introduced. The new generation of whitening skin care focuses on full-effect whitening, and the concept of natura...
