What is Kojic acid Powder?
Kojic acid is found in koji, which is what people eat and is safe to use. In recent years, a large number of patent documents have reported the application of kojic acid in cosmetics. Tyrosinase is a key enzyme in the production of melanin. Kojic acid can chelate copper with tyrosinase to inactivate it, which is the basis of its whitening effect. The results of clinical and application tests show that kojic acid has a strong inhibitory effect on melanin production in human skin, and is safe, non-toxic, and will not cause sequelae of leukoplakia. Kojic acid and other preparations (such as SOD, placenta extract, amino acid, sunscreen and various plant extracts, etc.) have a better effect. Kojic acid is mainly used in skin whitening products, anti-aging products, sunscreen products, whitening facial cleanser and beauty cosmetics. Kojic acid has certain antibacterial activity. Gram-negative bacteria are more sensitive to sodium kojate than gram-positive bacteria, while the opposite is true for most other antimicrobial substances. The antibacterial effect of kojic acid is much lower than that of other antibacterial substances, and its antibacterial activity is bacteriostatic rather than bactericidal. Kojic acid is ineffective against yeast, viruses and bacteriophages.
Function
(1) Kojic acid is widely used in food production. In the past, kojic acid was used to prevent rancidity due to its antioxidant properties. In recent years, it has been reported in literature that kojic acid has bactericidal and insect-resistant effects. It has obvious effects as a food preservative, preservative, and color-protecting agent, and can replace chemical Preservatives are widely used in color protection of meat food processing, preservation of fruits and vegetables, sterilization and preservation of raw food, and can also be used as preservatives for cut flowers to prolong the preservation and shelf life of flowers.
(2) As the raw material of food flavoring agent maltol and ethyl maltol
(3) Kojic acid can be used as a raw material for the production of cephalosporin antibiotics.
(4) In addition to being widely used in food processing, kojic acid also has good cosmetic effects of removing freckles and whitening. Kojic acid and its derivatives such as acetate have certain antibacterial properties and have no one-time or cumulative irritation to the skin. They can be used as preservatives for 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, and the effect is obvious when the dosage is 1-2.5%. Helps retain moisture and reduce skin wrinkles. Used in hair products to remove dandruff.
(5) Kojic acid can be used as raw material for seasoning and making larchetin and ethyl larchetin.
1. The efficient application of kojic acid in food, cosmetics, medicine and many other aspects determines its considerable economic value and great development potential.
2. As a new antiseptic and preservative, kojic acid will play an important role in the food, cosmetics and pharmaceutical industries.
