    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. 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.

    Product Description

    Our Sodium Bicarbonate is manufactured to meet strict international standards. It is non-toxic, non-flammable, and chemically stable under ordinary conditions.

    Key Features:

    1. High Purity: Minimum 99.0% content, meeting FCC (Food Chemicals Codex) and USP standards.
    2. Solubility: Dissolves easily in water to form a slightly alkaline solution (pH ~8.3).
    3. Reactivity: Reacts with acids to release carbon dioxide gas, which is the mechanism for its use in baking and fire suppression.
    4. Appearance: Free-flowing white powder with no clumps.

    Applications

    1. 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.
    2. 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.
    3. 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.
    4. 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.

    FAQ - Technical & Supply Chain

    • Q:

      How is Sodium Bicarbonate CAS 144-55-8 chemically distinguished for industrial and food applications?

      A: Sodium Bicarbonate (CAS 144-55-8) is chemically characterized as an acid salt of carbonic acid, known as Sodium hydrogen carbonate, and is supplied in varying grades of purity (Food, Feed, or Technical) depending on the permissible limit of impurities.
    • Q:

      Is this product effective as a leavening agent in food processing?

      A: Yes, this material is typically applied in baking and confectionery manufacturing, where it reacts with acidic components or thermal energy to release gas bubbles, ensuring the proper rise and texture of the final product.
