1. Applied in the field of cosmetics. In human skin, under the catalysis of tyrosinase, tyrosine and oxygen free radicals undergo complex oxidation and polymerization, and finally synthesize melanin. Kojic acid can inhibit tyrosinase synthesis, so it can strongly inhibit the formation of skin melanin, and is safe and non-toxic, and does not produce leukoplakia sequela. Kojic acid has been incorporated into make-up water, facial mask, emulsion and skin cream. It can be used to treat freckles, senile plaques, pigmentation, acne and other high-grade whitening cosmetics effectively. Kojic acid at the concentration of 20ug / ml can inhibit the activity of various tyrosinases (or polyphenol oxidase PPO) by 70 ~ 80%, and the general addition amount in cosmetics is 0.5 ~ 2.0%.

2. Food processing. Kojic acid can be used as food additive to keep fresh, antiseptic and antioxidant. Experiments show that kojic acid can inhibit the conversion of sodium nitrite into carcinogenic nitrosamine in bacon, and the addition of kojic acid to food will not affect the taste, aroma and texture of food; Kojic acid is also the raw material for the production of maltol and ethyl maltol. Kojic acid is widely used in food processing.

3. Medical field. Kojic acid has no mutagenic effect on eukaryotic cells, can eliminate the internal free radicals of human body and enhance the power of leukocytes, which is conducive to human health. Therefore, kojic acid has been used as the raw material of cephalosporin antibiotics. The finished drug produced is used to treat headache, toothache, local inflammation and other diseases, and the analgesic and anti-inflammatory effects are very ideal.

4. In agriculture. Kojic acid can be used to produce biological pesticides. Biological micro fertilizer (dark red liquid) made by adding 0.5 ~ 1.0% kojic acid, whether sprayed as foliar fertilizer at low concentration or made into growth and yield increasing agent for root application, this crop production accelerator has obvious yield increasing effect on grain and vegetables.

5. In other areas. Kojic acid can also be used as iron analysis reagent, film speckle remover, etc.

6. There is a risk of cancer.

7. Kojic acid and its derivatives are used as whitening agents in the cosmetics industry, and can also play the role of anti-corrosion and Moisturizing. It can be used as preservative and preservative in food industry; It can also be used as raw material for preparing flavoring agents maltol and ethyl maltol. It can also be used as an intermediate in the production of cephalosporin antibiotics. It can also be used to produce pesticides and pesticides.

8. Kojic acid and its derivatives such as acetate have certain Antibacterial properties and have no one-time and cumulative irritation to the skin. They can be used as Preservatives in cosmetics and food. It can strongly absorb ultraviolet rays and can be used alone or in combination with various sunscreen products, such as soap. It can treat and prevent the formation of skin spots such as liver spots. The effect is obvious when the dosage is 1% ~ 2.5%. Helps maintain moisture and reduce skin wrinkles.
