Application of Chinese yam in preparing whitening products

Abstract

The invention discloses application of Chinese yam in preparing whitening products. Chinese yam has an effective inhibition effect on tyrosinase and can inhibit generation of melanin, thereby realizing effects of whitening and spot removing.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine and the technical field of cosmetics, and in particular relates to the application of Chinese yam in preparing whitening products. Background technique [0002] With the gradual improvement of material living standards, people's pursuit of beauty is also constantly improving. Whitening and freckle removal are the goals pursued by most beauty-loving women. Skin color depends largely on the production of melanin, a high molecular biopigment, and the starting material for skin cells to "produce" melanin is tyrosine. Tyrosinase in melanoblasts reacts with tyrosine in the blood to produce a substance called "dopa", which is then converted into melanin. Therefore, by inhibiting the activity of tyrosinase, the synthesis of melanin can be effectively inhibited, so as to achieve the purpose of whitening and freckle removal. [0003] At present, the more effective whitening and freckle-removing...

Problems solved by technology

These substances are highly safe, but at the same time, there are also disadvantages of ineffective effects

The chemical name of arbutin: hydroquinone-β-D-glucopyranoside, which can slowly release hydroquinone to prevent the activity of the enzyme-tyrosinase that produces melanin, shows the effect of inhibiting melanin, and its arbutin does not It is toxic to melanocytes like hydroquinone, and it is a safe whitening and freckle-removing raw material, but the effect of arbutin is too slow, and its slow decomposition releases part of hydroquinone to inhibit the activity of tyrosinase, which is almost imperceptible, even if it is Long-term use of whitening and anti-freckle products containing arbutin has no obvious feeling, so that people gradually lose confidence in whitening and anti-freckle products added with arbutin; vitamin C can treat acquired pigmentation such as liver spots or Lille melanosis, Vitamin C and its derivatives are also considered to be safe whitening and freckle-removing materials, but they are not easily absorbed by the skin, the aqueous solution is easily oxidized and deteriorated, and it is very difficult to preserve. Later, people developed vitamin C palmitate, vitamin C phosphate magnesium, etc. Although the stability problem of vitamin C has been solved, these derivatives have poor water solubility, are not easy to add, and the efficacy of whitening and removing spots is obviously reduced; At the same time, it has a strong inhibitory effect on the production of melanin in human skin

Kojic acid has a strong inhibitory effect on human skin melanin production. It is usually used as skin whitening and sunscreen products in combination with other whitening and freckle-removing materials. Whitening and anti-freckle formulas are relatively rare
