Basic information on kojic acid
Pure kojic acid powder is a substance fermented by Aspergillus and is an exclusive melanin inhibitor. Its working principle is to change the three-dimensional structure of tyrosinase, prevent the activation of tyrosinase, and prevent the production of melanin.
Kojic acid, also known as kojic acid, is an excellent whitening ingredient, and its whitening activity can better inhibit tyrosinase than other whitening activities. It enters into the interstitial cells, which can retain water and increase skin elasticity. At present, it has been formulated into various cosmetics and can be made into whitening products for skin problems such as freckles, age spots, and acne.

Extraction and purification of kojic acid
1. Kojic acid combines with divalent metal ions to form insoluble metal chelates, which can be used during extraction.
2. Although kojic acid can be dissolved in water, its solubility is insignificant. Since the temperature has a significant influence on its solubility, it can be crystallized by cooling during concentration.
3. It can be used as an iron reagent. When kojic acid is used in a stainless steel fermentation tank, its fermentation broth will be reddish-brown. Because of this property, it also affects the extraction and refining process.
4. What are the methods for extracting kojic acid from fermentation broth? There are copper salt precipitation methods, ethyl acetate extraction methods, ether continuous extraction methods, concentration crystallization or freezing crystallization method, etc.
Can kojic acid be used during the day?
Kojic acid is best not to use during the day.
Kojic acid may lose its active ingredient in intense light or a too acidic environment. Therefore, cosmetic products containing kojic acid are best used alone at night, and avoid using them together with salicylic acid, fruit acid, and high-concentration VC.
