Still Essential: Ammonium Carbonate Across Industries
Ask a baker who specializes in traditional German Lebkuchen or Belgian Speculoos what makes their cookies crisp and light, and ammonium carbonate will likely come up. Often called baker's ammonia or salt of hartshorn, this white crystalline powder has been used in baking for centuries. Yet its value reaches far beyond the kitchen. Food processing, pharmaceuticals, agriculture, and industrial manufacturing all rely on it in one way or another.
If you're sourcing ammonium carbonate today——whether for a classic recipe or a modern production line——it helps to understand the compound a bit more fully. As a supplier working with customers in over 50 countries, Snowhite Chemical Co., LTD. regularly hears the same practical questions: What grade do I need? How stable is it in storage? Who can deliver consistent quality? The answers start with a clear picture of the material itself.
Chemical Background and Physical Properties
Ammonium carbonate (CAS 506-87-6) is actually a mixture of ammonium bicarbonate and ammonium carbamate. You'll typically receive it as a colorless crystal or a white crystalline powder with a noticeable ammonia smell.
One property that matters most in practice is thermal instability. Around 58 °C, the compound decomposes into ammonia, carbon dioxide, and water vapor——no solid residue left behind. This clean decomposition is why it works so well in certain baked products and as a foaming agent in industrial processes.
A few physical details worth keeping on file:
• Molecular weight: 96.09 g/mol
• Density: approximately 1.5–1.6 g/cm³
• Solubility: dissolves readily in cold water; hot water triggers decomposition
• pH in aqueous solution: roughly 9 at 20 °C (alkaline)
Where Ammonium Carbonate Is Used
The same compound shows up in surprisingly different settings:
Food and beverages
Traditional European holiday baking is the most famous example. Lebkuchen and Speculoos depend on ammonium carbonate to produce a crisp, open crumb and a distinctive taste that modern leavening agents cannot replicate. It works best in low-moisture products where the ammonia gas can escape completely during baking. It also serves as an acidity regulator.
Pharmaceuticals
Ammonium carbonate appears in smelling salts designed to stimulate breathing and revive consciousness. In cough syrups, it acts as an expectorant, helping to clear the respiratory tract. Pharmacopeia-grade quality is non-negotiable here; even small impurities carry clinical risk.
Industrial and agricultural uses
Beyond food and pharma, you will find it used as a nitrogen source in fertilizers, a mordant in textile dyeing, a buffering agent in chemical synthesis, and a foaming agent in the production of rubber and plastic foams.
Safety, Handling, and Storage
Regulatory status is straightforward. The EU recognizes ammonium carbonate as E503; the U.S. FDA considers it Generally Recognized as Safe (GRAS). That said, the material is an irritant——ammonia vapor affects the respiratory tract and mucous membranes. Adequate ventilation and appropriate protective equipment are a must during handling.
For storage, the rule is simple: keep it tightly sealed, cool, and dry, and separate from acids and strong oxidizers. Any moisture or temperature fluctuation risks early decomposition and ammonia release.
Sourcing Ammonium Carbonate: The Snowhite Chemical Approach
Having shipped fine chemicals to more than 50 countries since our formal establishment in 2010 (with roots tracing back to 2006), Snowhite Chemical Co., LTD. has seen how much variability exists in the ammonium carbonate market. That variability is exactly what we work to eliminate for our customers.
Our key areas of focus include:
Product scope and expertise: We specialize in benzene and toluene oxidation derivatives as well as chlorination derivatives of toluene and ethylbenzene. Ammonium carbonate sits within a portfolio backed by nearly two decades of production and supply experience.
Certifications that matter: ISO, Halal, and Kosher certifications cover our manufacturing sites and products, which simplifies market entry for clients across Europe, North and South America, the Middle East, Southeast Asia, and Africa.
Export volume and reliability: Annual exports exceed USD 50 million, and we are recognized as a major Chinese exporter of benzoic acid, sodium benzoate, benzyl benzoate, and related products. This scale brings stability to deliveries.
Packaging and documentation: We supply in standard 25 kg plastic-lined woven bags or fiber drums and provide full technical documentation. Custom packaging specifications are available on request.
A Market That Keeps Growing
Industry figures point to steady growth. The global ammonium carbonate market was valued at approximately USD 650.75 million in 2024, with projections placing it around USD 684.58 million in 2025 and above the one-billion-dollar mark by 2033, growing at a CAGR of about 5.2%. The drivers include widening use in processed foods, pharmaceutical manufacturing, and industrial foaming and cleaning formulations. As regulatory requirements tighten, demand shifts toward certified, consistent suppliers——exactly the kind Snowhite Chemical is positioned to be.
