Product Features & Advantages

Superior Whitening Mechanism

Kojic Acid effectively inhibits tyrosinase activity - the key enzyme responsible for melanin production. At concentrations as low as 20 µg/ml, it can inhibit 70-80% of tyrosinase activity, making it one of the most effective natural skin whitening agents available.

Potent Antioxidant Properties

Beyond its whitening capabilities, Kojic Acid demonstrates excellent antioxidant activity, effectively neutralizing free radicals and protecting skin from oxidative stress. This dual-action makes it ideal for anti-aging formulations when combined with other Natural Antioxidants.

Antibacterial and Antifungal Activity

The compound exhibits natural antimicrobial properties, making it suitable for acne treatments and products targeting skin infections. This additional benefit enhances its value in comprehensive skincare solutions.

Natural Origin and Safety Profile

Derived through natural fermentation processes, Kojic Acid is considered safe and non-toxic when used at recommended concentrations (0.5-2.0%). It does not cause adverse effects such as vitiligo, making it suitable for long-term use.

How to Use Kojic Acid Powder

Solubility Assessment
Kojic Acid is soluble in water, alcohol, and propylene glycol. Determine the optimal solvent for your formulation system based on compatibility with other ingredients.
Concentration Optimization
For cosmetic applications, use concentrations between 0.5-2.0%. For pharmaceutical applications, higher concentrations may be used under proper guidance.
pH Consideration
Formulate within pH range 4.0-6.0 for optimal stability and efficacy. Avoid highly alkaline conditions that may degrade the compound.
Incorporation Method
Dissolve in water phase at temperatures below 60°C. For best results, add after the heating phase to preserve activity.
Stability Testing
Conduct comprehensive stability testing including color stability, as Kojic Acid may darken over time in certain formulations.

Formulation Recommendations

Combine with Plant Extract ingredients for enhanced brightening effects
Use with stabilizing agents to prevent oxidation and discoloration
Consider encapsulation for improved stability in challenging formulations
Test compatibility with preservatives and other active ingredients
