Sodium Sesquicarbonate, commonly known as Sesquicarbonate, is a white crystalline compound with CAS number 533-96-0. Its molecular formula is Na2CO3·NaHCO3·2H2O, with a molecular weight of 226.03 g/mol. It is a double salt of sodium carbonate and sodium bicarbonate, occurring naturally as the mineral trona or produced synthetically. Our food grade product is manufactured under strict GMP conditions, with full compliance with global food safety standards including FCC, E500(ii) and GB 1886.229.

As a versatile food additive, sodium sesquicarbonate is widely used as a pH regulator, buffer and leavening agent in the food and beverage industry. It provides milder alkalinity than sodium carbonate and more stable pH buffering than sodium bicarbonate, making it ideal for a wide range of food applications. It is also extensively used in personal care products as a gentle exfoliant and pH adjuster, and in industrial applications as a cleaning agent and water softener.

Our food grade sodium sesquicarbonate is produced with advanced purification technology, with full batch traceability and complete supporting quality documents. We can provide customized specifications and packaging to meet specific customer requirements and ensure long-term stable bulk supply for global food and beverage manufacturers.

A1: Sodium sesquicarbonate is a double salt of sodium carbonate (soda ash) and sodium bicarbonate (baking soda). It has a pH of approximately 10.0, which is between sodium bicarbonate (pH 8.3) and sodium carbonate (pH 11.6). It provides more stable pH buffering than sodium bicarbonate and is gentler than sodium carbonate, making it ideal for many food and personal care applications.

A2: The recommended usage level varies by application:

• Baking products: 0.1-1.0%
• Beverages: 0.05-0.5%
• Dairy products: 0.01-0.3%
• Processed meats: 0.05-0.2%
• Canned foods: 0.01-0.1%

The exact concentration depends on the specific formulation and desired pH level. Always follow local food additive regulations.

A3: Yes, sodium sesquicarbonate is generally recognized as safe (GRAS) by the FDA and is approved for use as a food additive in most countries worldwide. It has a long history of safe use in food and personal care products.

A4: We provide all necessary food safety certificates including COA, MSDS, HALAL, KOSHER and FDA compliance documents. Our production facilities are certified under ISO 22000 and HACCP standards.

A5: Natural trona-derived sodium sesquicarbonate is approved for use in organic food products under certain conditions. Please contact us for detailed information on organic certification and compliance.

A6: Sodium sesquicarbonate is hygroscopic and will absorb moisture from the air. It should be stored in tightly sealed original containers in a cool, dry and well-ventilated area away from moisture and incompatible materials. Do not store near acids or strong oxidizing agents.
