di- SODIUM PHOSPHATE DIBASIC ANHYDROUS (DSP ANHYDROUS)

Di-Sodium Phosphate Dibasic Anhydrous (DSP Anhydrous), chemically represented as Na₂HPO₄, is an inorganic compound widely used as a buffering agent, emulsifier, and sequestrant. It is a highly soluble, white, crystalline powder with no odor. Due to its buffering capabilities, DSP Anhydrous is utilized in food, pharmaceuticals, water treatment, and industrial applications.

Applications of DSP Anhydrous

1. Food Industry:

• Buffering Agent: Regulates pH levels in food products such as processed cheese, dairy items, and beverages.
• Emulsifier: Used to stabilize and thicken emulsions in sauces, dressings, and soups.
• Sequestrant: Binds metal ions to prevent discoloration and rancidity in food products, improving shelf life.
• Leavening Agent: Acts as a component in baking powders, enhancing the rising process in baked goods.

2. Pharmaceutical Applications:

• pH Adjustment: Utilized in pharmaceutical formulations to maintain stable pH levels in syrups, tablets, and injectable drugs.
• Electrolyte Replacement: Included in oral rehydration solutions and electrolyte mixtures to restore ion balance.

3. Water Treatment:

• Corrosion Inhibitor: Acts as a corrosion-preventing agent in boiler water and cooling systems.
• Sequestrant: Controls water hardness by binding to calcium and magnesium ions in water treatment processes.

4. Industrial Applications:

• Textile Industry: Used in textile dyeing and finishing processes to maintain an optimal pH for dye uptake and color consistency.
• Cleaning Agents: Incorporated into detergents and cleaning formulations to improve efficiency by softening water.
• Ceramics and Glass Production: Used as a flux in ceramic glazes and glass manufacturing.

5. Laboratory and Analytical Uses:

• Buffer Preparation: Essential in laboratories for preparing buffer solutions in biochemical and analytical experiments.
• Chemical Reactions: Used as a reagent in synthesis and research processes.

6. Agriculture:

• Fertilizers: Provides phosphorus for soil enrichment in agricultural practices, enhancing plant growth.

Safety and Handling of DSP Anhydrous

Hazards:

While generally considered safe, Di-Sodium Phosphate Dibasic Anhydrous can cause irritation to the eyes, skin, and respiratory tract if mishandled. Ingesting large quantities may lead to gastrointestinal irritation.

Precautions:

• Personal Protective Equipment (PPE):
  • Gloves: Use protective gloves to prevent skin contact.
  • Eye Protection: Wear safety goggles to avoid eye irritation.
  • Respiratory Protection: Use a dust mask in areas with inadequate ventilation or where dust is generated.
  • Protective Clothing: Wear appropriate clothing to protect the skin from prolonged exposure.
• Storage:
  • Store in a cool, dry place.
  • Keep the container tightly sealed to prevent moisture absorption.
  • Avoid storing near incompatible materials, such as strong acids.
• Handling:
  • Avoid inhalation of dust and contact with skin or eyes.
  • Use in a well-ventilated area or under a fume hood.

First Aid Measures:

• Inhalation: Move the affected person to fresh air. Seek medical attention if symptoms persist.
• Skin Contact: Wash the affected area with soap and water. If irritation develops, seek medical advice.
• Eye Contact: Rinse the eyes with plenty of water for at least 15 minutes. Seek medical attention if irritation persists.
• Ingestion: Rinse the mouth with water and drink a glass of water. Do not induce vomiting and seek medical attention.

Disposal:

Dispose of DSP Anhydrous in compliance with local, state, and federal regulations. Avoid releasing large quantities into waterways.
