Kojic Acid

1. Product Overview & Market Relevance

Kojic acid is commonly found in the brewing of soy sauce, bean paste, and alcohol. It has been incorporated into high-end whitening cosmetics such as toners, masks, lotions, and skincare creams. It is completely non-toxic, soluble in water, and effective in small amounts, making it an ideal substance for pharmaceutical preservation as well.

2. Technical Highlights and Critical Parameters

2.1 Mechanism of Action

• Whitening/Melanin Suppression: Strongly suppresses the formation of skin melanin by inhibiting the synthesis of tyrosinase.
• Anti-bacterial: Exhibits good inhibitory effects on most bacteria and some yeasts, even at low concentrations.

2.2 Standard Technical Specifications

3. Market Positioning and Core Advantages

• Potency: A concentration of 20g/ml of Kojic acid can inhibit the activity of various tyrosinases (PPO) by 70%–80%.
• Safety Profile: It is safe and non-toxic, without causing post-leukoderma sequelae.
• Dual Efficacy: Possesses both anti-oxidant and strong anti-bacterial properties.
• Application Versatility: Soluble in water and effective in small amounts, making it ideal for high-end cosmetic and pharmaceutical preservation.

4. Formulation Guidelines

• Integration Phase: Since it is soluble in water, it can be easily incorporated into the aqueous phase of formulations.
• Concentration: Generally recommended addition of 0.5%–2.0% in cosmetics.
• Storage: Must be stored in tightly sealed and preferably full containers in a cool, dry, and ventilated area.
