Test Report

What is Kojic Acid?

Kojic acid is a natural organic acid produced by the fermentation of certain microorganisms (such as Aspergillus). It can inhibit tyrosinase and is one of the well-known whitening ingredients. Kojic acid also has antioxidant activity and is commonly used in products such as serums, creams, masks, lotions, and cleansers

Whitening Mechanism

01-Inhibit tyrosinase

Pure kojic acid is similar to VC and can combine with copper ions to inactivate tyrosinase.

02-Inhibit the production of melanin oxidation intermediates

Pure kojic acid can be oxidized by the intermediate product dopaquinone, thereby reducing the chain reaction substrate and inhibiting the conversion of the melanin intermediate product from the dopaquinone form to the final melanin. Because the effect is relatively strong, a lower concentration can achieve good results. Because the effect is too strong, it may cause skin redness and contact dermatitis, so most whitening products contain relatively low amounts.

What are its Effects?

1. Whitening

Best Kojic Acid Powder can compete with tyrosinase for copper ions, inactivate tyrosinase, block the production of melanin, and achieve the purpose of whitening and lightening spots. It can be achieved by adding 0.5~2.0% in cosmetics. To inhibit melanin production, kojic acid at a concentration of 20ug/ml can inhibit 70~80% of the activity of various tyrosinase enzymes. In human skin, tyrosine undergoes complex oxidation and polymerization with oxygen free radicals under the catalysis of tyrosinase, and finally synthesizes melanin. Kojic acid has the function of inhibiting the activity of the melanin-generating enzyme tyrosinase, and has a significant whitening effect without inhibiting other enzymes. It has good freckle removal and whitening effects. It is a commonly used cosmetic raw material and is widely used in lotions. , facial mask, lotion, skin cream, etc.

2. Freckle removal

Freckle-removing kojic acid can inhibit the synthesis of tyrosinase, so it can strongly inhibit the formation of melanin in the skin, and will not produce white spot sequelae. Therefore, kojic acid has been formulated into essences, facial masks, lotions, and skin care creams to effectively treat freckles. , age spots and chloasma products.

3. Antioxidant

In addition to whitening and removing freckles, kojic acid also has free radical scavenging and antioxidant effects. It can help tighten skin, promote protein aggregation, and tighten skin. It not only has certain antibacterial properties, but also has certain moisturizing capabilities, and can even be used as a preservative in food and cosmetics. Because kojic acid can inhibit the activity of hyaluronidase, it can also inhibit allergies.

Preparation of Kojic Acid by Fermentation

Best Kojic Acid Powder is a secondary metabolite derived from microorganisms. It is produced by the fermentation of edible koji fungi such as Aspergillus oryzae. It is present in soy sauce, bean paste, and wine brews. Many fermented products fermented by Aspergillus The presence of kojic acid can be detected in . Industrial production of kojic acid mostly uses glucose as raw material and is produced by fermentation of Aspergillus Candida.

Kojic acid has a simple structure, but due to the certain instability of its enol structure, it is often used as a skeleton for modification and derivatization, such as the synthesis of kojic acid dipalmitate, kojic acid ester, etc. These derivatives not only improve the performance of kojic acid in The solubility and stability in oily cosmetics, and the biological activity are also greatly improved.

Regulatory Status & Safety

China: Kojic acid is included in the "Catalogue of Used Cosmetic Ingredients (2021 Edition)". Currently, China has not set specific usage limits for kojic acid. Kojic acid can be used as a functional ingredient in skin-whitening and blemish-removing cosmetics, and can also be used in some ordinary cosmetics. Studies have shown that when the concentration of kojic acid exceeds 1%, it may increase the risk of irritation such as contact dermatitis, and high concentrations may have some cytotoxicity.

European Union: EC No. 1223/2009 currently does not set legal usage limits for kojic acid. On March 17, 2022, the European Scientific Committee on Consumer Safety (SCCS) issued its final safety assessment opinion: When used as a whitening agent, the recommended maximum concentration of kojic acid in final cosmetic products is 0.7%.

Japan: Japan reinstated the use of kojic acid in cosmetics in 2005. Although there are no mandatory legal limits, the industry generally recommends an added concentration of 0.1%–2%.

United States: Kojic acid is widely used in various cosmetics, including skincare and bath products, under the FDA's Voluntary Cosmetic Registration Program (VCRP). Industry surveys show that kojic acid is typically added at concentrations of 0.1%–2%, with higher concentrations mainly used in creams and lotions. The Cosmetic Ingredient Evaluation Committee (CIR) considers kojic acid to have good safety profiles within the 0.5%–2% concentration range under specified usage conditions.
