Directory Guidance on Kojic Acid Powder
Chemical Structure
Basic Info
Kojic acid is also called kojic or kojic acids. It is produced by Aspergillus Candida at 30degC by aerobic fermentation. Its molecular form is a g pyrone with an substituent. Kojic Acid powder and maltol are the only g-pyrones that exist in nature. Saito isolated kojic acids crystals in 1907 from rice koji. Yabuta named it in 1912, and its structure was established in 1924. Arnstela, in 1953 (surface fermentation), and Kitada Makuo, in 1971 (submerged fermentaion), used isotope-tracking technology to prove kojic acids are formed by direct oxidation without carbon frame rupture.
Kojic crystals are colorless, prismatic and needle-shaped. Kojic acid dissolves easily in alcohol, water, and acetone. It is slightly soluble, however, in ether and chloroform. Purification can be achieved by crystallization of the acid in solvents like ethyl-acetate and acetone, or by sublimation at reduced pressure between 150-200. Literature reports a melting point of 151-154. The absorption peak of Kojic Acid Powder, and its 5,7 diethyl ester derivative is 315nm.
Kojic acid can be destroyed by heat and light. If a 0.5% solution of kojic is exposed to sunlight or treated for 3h with different pH, it will turn light yellow.
Kojic acid reacts ferric chloride and produces a red color that can be used for measuring Kojic Acid powder. Kojic Acid can be used to reduce Fehling’s reagent, silver nitrate and ammonia. The molecular structure of kojic acid contains an alcoholic group close to the carbonyl, which can be used to form salts. Other hydroxyl groups are able form ethers and ester derivatives.

1. Cosmetics and skin products
Kojic Acid Powder is used to lighten spots and whiten skin. It inhibits tyrosinase activity and stops the production of Melanin. Skin care products like whitening creams and essences are commonly used to reduce spots and brighten skin. It is a core ingredient in many whitening products, which is especially useful for melasma and freckles.
Kojic acid powder is a powerful antioxidant that can delay the aging of skin. It is commonly used in anti-aging creams. It can be used in combination with other antioxidants (such as Vitamin C and Vitamin E) to improve the skin care effects.
Antibacterial and antiseptic – The antibacterial properties in Kojic Acid Powder help to prolong the shelf life of cosmetics. It can also be used to inhibit acne-related bacteria, making it a good choice for anti-acne and oil control products.
Improvement of stability: Kojic acids (such as the kojic dipalmitate derivative) have been developed in recent years to improve their skin permeability, increase their stability, and reduce irritation.
2. Food Industry
Kojic Acid Powder can be used for food preservation. It has antibacterial and antioxidative effects. Kojic acid, for example, can be used to preserve aquatic products, fruits and vegetables and meat.
Fermented Foods: Kojic Acid powder is a natural additive in many fermented food products (such as miso, rice wine, and soy sauce), which enhances the taste and stability of foods. It is a metabolite of fermented food that is produced by Aspergillus spp. during the fermentation process.
Food Additive – Kojic Acid Powder is a natural food additive that can be used to enhance the color and texture of foods while also providing antioxidant protection.
3. Medical Field
Kojic Acid Powder can be used as a skin treatment to treat pigmentation disorders such as freckles, age marks, etc. As an external medicine. It can be used to repair skin after surgery and reduce pigmentation or scars.
Antimicrobial drugs. Kojic Acid Powder has antimicrobial properties that make it an ideal candidate for use in medicine. It can be used as a base to create antimicrobial drugs and topical disinfectants. It is effective in treating skin infections and has inhibitory properties against a wide range of bacteria and fungi.
Recent studies have indicated that Kojic Acid powder may have anticancer properties. The research is still at the early stages, but it has an inhibitory action on cancer cells.
4. Agriculture and Plant Protection
Kojic Acid Powder is a natural antimicrobial that can be used to prevent and control plant disease. It can be used as a pesticide that is environmentally friendly and has an inhibitory action on some plant pathogens.
Kojic Acid Powder regulates plant growth. Studies have shown it has a regulatory impact on certain plants. It can be used to improve crop quality or increase yields. It can, for example, promote root growth and stress resistance in the plants.
Postharvest preservation – Kojic acid is used to preserve fruits and vegetables after harvest. It delays decay and oxidation, and increases shelf life.
5. Research and Development
Kojic Acid Powder can be used as an intermediate in organic synthesis to create new materials such as antibacterial films, biodegradable materials or antioxidant coatings. The application potential of this material in polymer materials will be explored.
Kojic Acid powder is used to investigate the application of its antibacterial, antioxidant and whitening mechanisms in biotechnology research. The production efficiency of the kojic acids can be increased through genetic engineering, or derivatives of kojic acids can be developed in order to increase its application range.
Environmental Science: Kojic Acid powder has antibacterial and antioxidant properties that make it a good candidate for environmental science applications, like water treatment or the degradation of pollutants.
