Kojic Acid
The Potent Tyrosinase Inhibitor and Whitening Agent
Kojic acid is a weakly acidic organic compound made through the fermentation pathway of microorganisms. It can strongly suppress the formation of skin melanin by inhibiting the synthesis of tyrosinase. It is safe, non-toxic, and effective against freckles, age spots, pigmentation, and acne.
| INCI Name | Kojic Acid |
|---|---|
| CAS No. | 501-30-4 |
| Source | Made of microorganisms through fermentation pathway |
| Core Function | Strong melanin suppression, treats freckles/age spots/pigmentation, anti-bacterial, anti-oxidant. |
1. Product Overview: The Bio-Fermented Gold Standard for Brightening
Shaanxi Huatai Bio-fine Chemical Co. provides professional-grade Kojic Acid (≥99%), a high-performance active derived from traditional fermentation processes. Recognized globally as a powerhouse in the hyperpigmentation sector, our Kojic Acid offers unparalleled tyrosinase inhibition—up to 80% efficacy at minimal concentrations—to address freckles, age spots, and melasma. Beyond its cosmetic brightening capabilities, its natural anti-bacterial profile provides a unique dual-action benefit, serving as both an active for clear-skin formulations and a functional stabilizer in high-end pharmaceutical and cosmetic systems.
Core Features & Primary Benefits:
-
Master Tyrosinase Inhibition: Directly targets the enzyme responsible for melanogenesis, offering a potent, natural-origin alternative for erasing stubborn dark spots.
-
Dual-Spectrum Efficacy: Combines aggressive brightening with a robust anti-bacterial/anti-yeast defense, creating a cleaner, clearer complexion while protecting the formula’s integrity.
-
High-Purity Bio-Performance: At ≥99% purity, this crystalline active delivers predictable, consistent results in whitening serums, masks, and professional-grade lotions.

3. Biological Mechanisms of Action
Our Kojic Acid optimizes skin tone and microbial balance through two high-precision pathways:
| Action Pathway | Biological Impact |
| Melanin-Pathway Blockade | Inhibits the enzymatic synthesis of tyrosinase (PPO), effectively halting melanin production at the source. |
| Broad-Spectrum Bio-Inhibition | Suppresses pathogenic bacterial strains (e.g., E. coli, S. aureus, Streptococcus), supporting a healthy and clear skin surface. |
4. Formulation & Processing Directives
| Formulation Parameter | Recommendation | Application Note |
| Suggested Dosage | 0.5% – 2.0% | Functional dose; 1.0–2.0% provides intensive brightening and age-spot correction. |
| Processing Instructions | Aqueous Integration | Highly water-soluble; add directly to the aqueous phase under moderate shear mixing. |
| Stability Strategy | Tightly Sealed/Cool/Dark | Protect from oxidation and light-induced browning to maintain the pristine white/beige color profile. |
| Aesthetic Management | Opaque Housing | Highly recommended for all high-concentration Kojic Acid formulas to ensure maximum shelf-life and aesthetic purity. |
