What is Sodium Bicarbonate CAS 144-55-8?

Sodium Bicarbonate CAS 144-55-8 is sodium hydrogen carbonate, with the formula NaHCO3 or CHNaO3 and molecular weight 84.01 g/mol. It is commonly known as baking soda or bicarbonate of soda.

How does Sodium Bicarbonate work as a leavening agent?

It reacts with acidic ingredients or heat to release carbon dioxide gas, which creates rise and texture in baked goods and confectionery. The reaction is the same principle behind its use in effervescent products.

What is the difference between food, feed, and industrial grades?

The main differences are assay and allowable impurity levels. Food and feed grades are controlled for limits such as arsenic, heavy metals, chloride, and iron, while industrial grade is specified for technical applications where those limits may be broader.

What pH and buffering properties does Sodium Bicarbonate provide?

In water it forms a mildly alkaline solution, typically around pH 8.3, and can act as a pH regulator or buffer. This makes it useful in foods, beverages, personal care, cleaning products, and water or gas treatment.

What are common non-food uses of Sodium Bicarbonate?

Non-food uses include dry chemical fire suppression, feed buffering, flue-gas treatment, gentle cleaning, rubber or plastics foaming, and laboratory pH adjustment. It is widely used because it is low-cost, non-flammable, and comparatively mild.

Sodium Bicarbonate CAS 144-55-8

Sodium Bicarbonate (CAS 144-55-8) is a versatile alkaline salt utilized as a primary leavening agent in bakery food production and a pH buffering agent in animal feed. Chemically identified as Sodium hydrogen carbonate or Baking soda, this white crystalline powder functions to release carbon dioxide when heated or reacted with acids, creating the porous texture in cakes and breads. As a mild Carbonic acid monosodium salt, it is also extensively utilized in flue gas desulfurization and as a gentle abrasive in industrial cleaning. Where a stronger alkaline carbonate is specified, Sodium Carbonate is a related product to assess against the formulation requirements. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific particle size distribution (e.g., Food Grade vs. Industrial Grade). Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

Applications

Food Industry: Used as a leavening agent for bread, cakes, and biscuits; acts as a carbon dioxide generator in sodas and cold drinks; used as a preservative for butter.
Animal Feed: Added to feed as a buffer to neutralize acidity in the rumen, improve heat stress resistance, and enhance feed efficiency in poultry and dairy cattle.
Industrial Applications:
- Desulfurization: Used in Flue Gas Desulfurization (FGD) to remove sulfur dioxide from exhaust gases.
- Detergents: A filler and buffering agent in washing powders.
- Leather Tanning: Used to neutralize tanning agents.
- Fire Extinguishers: A component of dry chemical fire extinguishers.
Personal Care: Used in bath bombs, toothpaste, and mouthwash formulations.

Storage Conditions

Environment: Store in a cool, dry, and well-ventilated warehouse.
Moisture Protection: Sodium Bicarbonate is sensitive to moisture and can cake (clump) if exposed to humid air. Keep bags tightly closed.
Incompatibility: Store away from acids. Do not store near toxic substances if intended for food use.
Shelf Life: 24 months in original packaging.

Safety Precautions

Handling: Generally considered safe (GRAS). However, industrial handling may generate dust. Use with adequate ventilation.
Reaction: Reacts violently with acids to produce carbon dioxide gas.
Contact:
- Eyes: Dust may cause mild mechanical irritation. Rinse with water.
- Skin: Prolonged contact may cause dryness or irritation. Wash with soap and water.
- Ingestion: Safe in food amounts, but large industrial quantities should not be ingested.
