Scientific Overview & Manufacturing Excellence
We specialize in the contract manufacturing and stable bulk supply of 98% Kojic Acid, a highly advanced cosmetic active meticulously produced through precision synthesis. Recognized globally by elite dermatological formulation scientists, Kojic Acid functions as a cutting-edge skin-brightening API renowned for its profound tyrosinase-inhibiting capacity, targeted dark spot fading, and gentle exfoliating properties.
Our facility utilizes state-of-the-art synthetic pathways and multi-stage crystallization technologies to yield a highly pure, stable active compound. The finished product presents as distinct white needle-like crystals or a fine uniform powder, characterized by excellent water solubility and biological efficacy. All production processes are executed in GMP-standard dust-free workshops with full ISO9001 certification and complete batch traceability, ensuring a strict ≥98.0% purity index via precise HPLC detection.
Target Application Scenarios & Formulation Benefits
Our 98% HPLC-grade Kojic Acid complies with stringent international cosmetic raw material safety regulations. Its multi-target brightening profile makes it widely utilized in:
✔ Melanin Inhibition & Spot Fading: Effectively chelates copper ions at the active site of tyrosinase, directly inhibiting melanin production. It actively fades stubborn hyperpigmentation, age spots, and residual acne marks, significantly brightening dull skin.
✔ Tone Correction & Radiance: Dramatically improves uneven skin tone caused by excessive UV sun exposure and environmental damage. It clears entrenched dullness, promoting a vibrant, clear, and radiant dermal complexion.
✔ Gentle Exfoliation & Texture Refinement: Gently exfoliates excess dead skin cells from the stratum corneum. By accelerating cellular turnover, it refines rough texture and continuously keeps the skin fair and smooth.

Precautions & Formulation Guidelines
Oxidation & Stability: Kojic Acid is highly sensitive to light, heat, and metal ions. To prevent the finished cosmetic formulation from oxidizing and turning yellow or brown over time, formulators must incorporate chelating agents (like EDTA) and antioxidants (like Sodium Metabisulfite or Vitamin E).
pH Consideration: The ingredient exhibits maximum stability in slightly acidic environments. Maintain the formulation's final pH between 3.5 and 5.0 to ensure long-term clinical efficacy and aesthetic stability.
Storage Notice: Keep tightly sealed after opening the package. The pure white needle-like crystals must be stored away from any UV exposure or elevated temperatures to preserve their crystalline structure and color.
Production Operation Protection: Personnel should wear standard dust masks and gloves during weighing and feeding to prevent the inhalation of fine crystalline dust.
Frequently Asked Questions (Procurement & Formulation)
Why does Kojic Acid sometimes cause cosmetic creams to turn yellow?
Kojic Acid is a reactive molecule that easily oxidizes when exposed to UV light, high heat, or trace metal ions in the water phase. This oxidation process alters its structure, resulting in a yellowish or brownish tint in the finished cream. To prevent this, always formulate with purified water, add a chelating agent (like Disodium EDTA), and include a stabilizing antioxidant system.
How exactly does Kojic Acid inhibit melanin production?
Melanin synthesis in the skin requires the enzyme tyrosinase, which relies on copper ions to function. Kojic Acid effectively chelates (binds to) these copper ions at the enzyme's active site. By neutralizing the copper, it deactivates tyrosinase, directly blocking the conversion of tyrosine into melanin and thereby preventing the formation of dark spots.
Do you supply finished cosmetic creams or retail serums?
No. We are strictly an upstream B2B raw material manufacturer and supplier. We provide bulk Kojic Acid 98% powder to empower pharmaceutical companies, cosmetic brands, and laboratories to manufacture their own retail products. We do not sell finished retail formulations.
Can you provide samples and complete test certificates for customs clearance?
Yes, we provide sample testing for quality and formulation verification for qualified B2B buyers. Each commercial bulk order comes with an official Certificate of Analysis (COA) specifying HPLC results, commercial invoice, packing list, and MSDS to ensure smooth global customs clearance and product filing.
