What is Kojic Acid Powder?
Kojic Acid Powder is a kind of specialized inhibitor for melanin. It can prevent tyrosinase activity by synthesizing with copper ion in the cells after it enters skin cells. Kojic acid and its derivative have a better inhibitory effect on tyrosinase than any other skin whitening agents. At present, it is assigned into various kinds of cosmetics for curing freckles, spots on the skin of old man, pigmentation, and acne.

What is the mechanism of Kojic Powder?
* Tyrosinase inhibition ability:
Kojic acid at a concentration of 20ug/ml can inhibit 70%-80% of the activity of tyrosinase (or polyphenol oxidase PPO) from different sources.
* Antibacterial ability:
0.2%-0.5% kojic acid can inhibit the growth of a variety of bacteria.
* Oxidation resistance:
The phenolic hydroxyl of kojic acid can be reduced.
* Chelation of metal ions:
It can chelate with Fe, Cu, Mn, and other metal ions.

Kojic Acid Powder Benefits
In the Field of Cosmetics:
Skin whitening and Freckle-removing
Whitening principle: Kojic acid binds to copper in black cells and inactivates tyrosinase.
"Kojic acid" has a good whitening effect and can lighten dark spots. After this application was discovered, "kojic acid" began to be used as a skin lightening agent and was widely used in whitening and spot lightening products.
"Melanin" is the core component that leads to the darkening of the skin and the appearance of pigmentation. It inhibits the production of melanin, which can whiten and fade spots. In the process of melanin production, "tyrosinase" is an essential catalyst. "Kojic acid" can compete with tyrosinase for copper ions, make tyrosinase inactive, block the production of melanin, and achieve the purpose of whitening and fading.
Food Additives:
Strong antibacterial ability
Thermostabilization
Soluble in water
Agriculture
Plat growth accelerator: It has the obvious effect of increasing the yield of grain and vegetables.
Insecticidal synergist: Kojic acid can inhibit hexosaminidase in insects and reduce their immunity.
Medicine
The raw material of antibiotics: Used in the treatment of headache, toothache, and local inflammation, analgesia, and anti-inflammatory effects are very ideal.
Dosage
* In cosmetics: It is generally recommended to add 0.5% ~ 2.0%.
* In agriculture:
Biological micro fertilizer: adding 0.5~1.0% kojic acid.
Pesticide: 2%~5%
Application of Pure Kojic Acid Powder
* In Cosmetics:
Kojic acid functions as an antioxidant and whitening in cosmetic products.
It can effectively treat freckles, old age spots, pigmentation, acne, and so on.
* In Pesticides:
Kojic acid can be used in pesticide application, whether as foliar fertilizer for spraying (low concentration) or as growth and yield enhancer for root application.
It has obvious effects on grain and vegetable yield increase, and can also be used as an insecticide or insecticidal fungus synergist.
