Description

Ammonium Carbonate is a versatile inorganic salt known for its unique decomposition properties. This compound is essential in applications requiring a gentle leavening action or a source of ammonia. It is a critical raw material for the food, pharmaceutical, and specialty chemical industries. Global buyers rely on our supply for consistent quality and reliable performance in their formulations.

Application

• Food Industry: Primarily used as a leavening agent in flat baked goods like crackers and cookies, where rapid gas release at low temperatures is required.
• Pharmaceuticals: Serves as an active ingredient in smelling salts and expectorants, and as a pH adjuster in various medicinal preparations.
• Laboratory & Analytical Chemistry: Employed as a buffer component and a source of ammonia in qualitative inorganic analysis.
• Textile & Leather Processing: Used in dyeing and printing processes, and as a neutralizing agent in leather tanning.
• Fire Extinguishers: Acts as a propellant in some older models of fire extinguishers.
• Flavoring Agent: Imparts a distinctive pungent flavor and aroma, historically used in products like saleratus and certain traditional confections.
• Metal Finishing: Finds use in surface treatment and cleaning applications for specific metals.
• Fertilizer & Agriculture: Provides a readily available source of nitrogen for plant nutrition in specific formulations.

Quality Control

Our Ammonium Carbonate is manufactured and tested under strict quality management systems. We offer grades compliant with Food Chemical Codex (FCC) and technical specifications to meet diverse industrial needs. Every batch undergoes rigorous analytical testing to ensure purity, identity, and performance. Certificates of Analysis (COA) are available upon request to guarantee traceability and compliance with your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its highly volatile and hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent decomposition and caking. Isolate from strong acids and excessive heat.
