Potassium Carbonate 99.5% Min Fine Powder – High-Purity Korean K₂CO₃ for Food Grade E501(i) & Pharmaceuticals (25Kg Bag)

Potassium carbonate 99.5 fine powder (chemical designation: k2co3 powder korea, molecular formula K₂CO₃) is an industrial-strength, ultra-pure alkaline mineral compound directly imported from South Korea (Made in Korea). Certified compliant with prestigious compendial monographs including Food Chemicals Codex IV (FCC IV), European food additive regulation e501i potassium carbonate (INS 501(i)), Halal, and Kosher certifications, it guarantees a total alkali assay of minimum ≥ 99.5% Min. Characterized by a fine crystalline powder morphology with ultra-low chloride (KCl ≤ 0.01%) and trace iron (Fe ≤ 3 ppm), this food grade potassium carbonate dissolves rapidly into a sparkling, water-clear alkaline liquor without sediment. Packaged in moisture-resistant 25.0 Kg Net bags, it is the premier choice for commercial noodle manufacturing (kansui), cocoa Dutching, optical glass strengthening, and pharmaceutical synthesis, making it ideal for facilities looking to buy potassium carbonate 25kg bulk.

Technical Specification Standards – Potassium Carbonate 99.5% Fine Powder (Specifications)

Chemical Dynamics & Key Technological Advantages

• Food & Compendial Purity (≥ 99.5% Assay): Manufactured under strict Korean quality control protocols, this product restricts trace iron (Fe ≤ 3 ppm), chloride (KCl ≤ 0.01%), and heavy metals (As ≤ 0.1 ppm, Pb ≤ 5 ppm) to microscopic limits. When dissolved in water, it yields a crystal-clear, water-white alkaline solution with zero sediment, preserving true flavor profiles and brilliant product aesthetics.
• Fine Powder Particle Morphology (ASTM #270 ≤ 30%): Unlike coarse crystalline granules that dissolve slowly and require extensive heating, the ultra-fine powder profile offers a high surface-area-to-volume ratio. It dissolves rapidly in ambient water and integrates uniformly into dry flour mixes, dough conditioners, and pharmaceutical powder blends without lumping.
• Controlled Alkaline Buffering & Texture Enhancement: Potassium carbonate acts as a stable alkaline buffering agent that provides gentle, controllable pH regulation. In wheat noodle manufacturing, the potassium cations (K⁺) cross-link with gluten proteins, increasing tensile elasticity, imparting an authentic golden-yellow hue, and preventing noodles from becoming soggy or sour.
• Comprehensive International Quality Certifications: Fully certified compliant with Food Chemicals Codex IV (FCC IV), European Regulation E501(i), Halal, and Kosher directives, ensuring legal compliance and market access for commercial food exports worldwide.

Core Practical Applications Across Food, Pharma & Technical Sectors

Engineered for high chemical consistency and exceptional solubility, food grade potassium carbonate serves diverse functional roles:

• Food & Beverage Processing (E501i Food Additive):
  • Instant & Fresh Noodles (Kansui Alkaline Agent): Essential component in lye water formulations, neutralizing natural flour acidity to enhance chewiness, springy bite, and golden coloration.
  • Cocoa & Chocolate Processing (Dutching Process): Neutralizes natural cocoa bean acidity, softens astringent bitterness, deepens rich chocolate aroma, and imparts a lustrous dark brown tone.
  • Bakery Goods & Confectionery: Functions as an efficient leavening agent releasing carbon dioxide gas, an acid regulator, and a textural stabilizer in jellies and puddings.
• Pharmaceuticals & Fine Chemical Synthesis:
  • Used as a high-purity alkaline intermediate in the chemical synthesis of active pharmaceutical ingredients (APIs) and specialty agrochemicals.
  • Serves as a clean potassium reactant for manufacturing specialty reagent-grade potassium salts.
• Optical Glass & Technical Ceramics:
  • Supplies essential K₂O flux to enhance refractive index, optical transmission, mechanical surface hardness, and thermal shock resistance in high-grade display glass and laboratory ware.
  • Acts as a melting flux in ceramic glazes, ensuring a smooth, defect-free vitreous surface finish.
• Industrial Gas Scrubbing & Agriculture:
  • Acid gas absorption agent for removing CO₂ and H₂S from industrial process synthesis gas streams.
  • Soluble alkaline potassium source utilized in specialized soil de-acidification and chloride-free crop nutrition formulations.

Technical Dosing Guidelines, Handling & Storage Protocols

• Food Processing Application Guidelines: Apply strictly in accordance with Good Manufacturing Practice (GMP) principles and national food additive usage standards. Gradually add the fine powder into ambient water under continuous mechanical agitation; the powder dissolves rapidly with slight heat release.
• Personnel Protective Equipment (PPE): Potassium carbonate is mildly alkaline and can cause ocular discomfort, skin dryness, or respiratory irritation if fine powder dust is inhaled. Operators handling bulk bags should wear protective dust masks, safety goggles, and rubber gloves.
• Emergency First Aid Measures: In case of contact with eyes or skin, flush immediately with copious clean water for at least 15 minutes. In case of inhalation of concentrated dust, move the individual to fresh air immediately.
• Warehouse Storage Protocol: Potassium carbonate is intensely hygroscopic and absorbs atmospheric moisture and carbon dioxide if exposed. Store on elevated pallets in a cool, clean, well-ventilated dry warehouse away from direct sunlight. After partial opening, tightly fold, seal, and tape the inner polyethylene liner to prevent air contact and caking.

Frequently Asked Questions (FAQ)

1. Why is Potassium Carbonate (K₂CO₃) preferred over Sodium Carbonate (Na₂CO₃) in ramen noodles?

While both compounds provide alkaline conditions, potassium ions (K⁺) interact with wheat gluten to yield a crisp, springy, and tender bite without the rubbery hardness associated with pure sodium carbonate. Additionally, potassium carbonate imparts a more vibrant, natural golden-yellow color and eliminates harsh soapy aftertastes.

2. What is the role of food grade K₂CO₃ in the cocoa Dutching process?

Natural raw cocoa powder is acidic (pH 5.0 – 5.6) with sharp astringency. Dutching with potassium carbonate neutralizes the natural acidity to pH 6.8 – 7.5. This removes sourness, enhances natural chocolate aromatics, increases powder wettability in milk, and yields an appealing deep brown tone.

3. Why does Potassium Carbonate fine powder tend to cake if bags are left unsealed?

Potassium carbonate is strongly deliquescent and absorbs atmospheric moisture very rapidly. If stored in high relative humidity or left unsealed, surface moisture migration binds powder particles into hard lumps. Although chemical purity remains unaffected, bags must be stored on dry pallets and inner liners kept tightly sealed to maintain a free-flowing powder habit.

4. Does THP Chemical provide batch COAs and VAT invoices for 25kg bag orders?

Yes. THP Chemical supplies batch-specific factory Certificates of Analysis (COA), 16-section MSDS sheets, and legal commercial VAT invoices with every wholesale order to satisfy corporate food safety and regulatory compliance audits[cite: 3].
