Kojic Acid Powder Supplier

Kojic acid bulk is 5-hydroxy-2-hydroxymethyl-4-pyrone, a strong tyrosinase inhibitor made through controlled aerobic fermentation of Aspergillus oryzae using carbohydrate sources.This pharmaceutical material works by binding to the copper ions in the tyrosinase enzyme, which stops melanin from forming inside cells.Our kojic acid bulk powder is a white or light off-white crystalline powder with a molecular weight of 142.11 g/mol.

Third Test Report

Testing Method: We work with globally recognised third-party laboratories such as SGS and Eurofins to do complete quality verification. Every batch undergoes stringent testing including HPLC to certify purity, Atomic Absorption Spectrophotometry for detection of heavy metals and microbiological testing utilising modern biochemical incubators. We go beyond international requirements to make sure our products are safe and effective.

Pesticide Residue Testing: Every sample is tested for over 200 common pesticide chemicals using gas chromatography-mass spectrometry, and the findings are consistently non-detectable, meeting EU and FDA criteria.

Heavy Metal Testing: Iron concentration is tightly limited to less than 5ppm to prevent colour problems and total heavy metals are less than 10ppm. Lead, arsenic, mercury and cadmium readings are regularly within USP grade standards.

Pure Kojic Acid Powder Advantages

Superior Purity Level: Our fermentation derived product is purified to >99% purity using modern crystallisation procedures providing optimum efficacy and low contaminants that could impact formulation stability.

Enhanced Stability Profile: We have formulated new Packaging protocols with the application of double-layer PE bags within fibre drums, which protects Pure Kojic Acid Powder from light exposure and moisture infiltration hence extending its shelf life significantly to 24 months when stored under appropriate conditions.

Excellent Solubility: Dissolves entirely in water and ethanol at room temperature in its fine crystalline state. This makes the formulation procedures easy and ensures uniform distribution in your final products.

Pure Kojic Acid Powder Application

Skin Brightening Formulations: Used in serums, creams and lotions for hyperpigmentation, age spots, melasma and uneven skin tone at 1-2% concentrations. The chemical is efficient to suppress melanin synthesis upon application to the skin.

Anti-Aging Products: Mixes with antioxidants in advanced anti-aging treatments where it captures free radicals, boosting collagen-supporting chemicals for a complete skin transformation.

Soap & Cleansing Bars: Added at 0.5-1% in melt-and-pour or cold process soaps for gradual skin lightening results with daily cleansing procedures.

Professional Treatment Products:Used at higher doses (2-4%) in professional spa peels and clinical treatments aimed against recalcitrant pigmentation under controlled application settings.

Production Process

Step 1 - Strain Selection and Preparation: We cultivate unique Aspergillus oryzae strains kept in our temperature-controlled culture library.

Step 2 - Fermentation Substrate Preparation: High quality rice substrates are sterilised in autoclave systems at 121°C for 30 minutes, then chilled to suitable inoculation temperature.

Step 3 - Controlled Aerobic Fermentation: The inoculated substrates are incubated for 7-10 days at 28-30°C under strict control of oxygen and humidity.

Step 4 - Extraction and Filtration: Fermentation broth is passed through multi-stage filtration systems eliminating mycelial biomass and solid particles.

Step 5 - Crystallisation and Purification: The pH adjusted extract is subjected to controlled cooling crystallisation. The crystallised material is separated by centrifugation and re-crystallized in cycles.

Step 6 - Drying and Milling: Crystals are vacuum dried at low temperatures to preserve chemical integrity and milled to a consistent particle size.

Step 7 - Quality Testing and Packaging: Each batch is subjected to exhaustive HPLC, heavy metal and microbiological testing prior to being packed in double-layer PE bags in fibre drums.
