1. Food & Healthcare Ingredients

• Leavening Agent: Ammonium carbonate releases carbon dioxide gas when heated, causing dough to rise and creating a light, airy texture in baked goods. 
• pH Control: It can act as a pH regulator in some food processing, helping to stabilize the acidity of certain products.

2. Pharmaceuticals

• Smelling Salts: Ammonium carbonate is a key component of smelling salts, which are used to revive someone who has fainted or is feeling faint.
• Buffering Agent: Ammonium carbonate is a weak base and salt of a weak acid, making it useful as a buffer in various chemical reactions and pharmaceutical formulations.

3. Performance Chemicals

• Synthesis of other Ammonium Salts: Ammonium carbonate is been used to produce other ammonium salts through metathesis reactions.
• Organic Synthesis: Ammonium carbonate is employed in the synthesis of various organic compounds, including quaternary ammonium compounds, which are often used as surfactants and antimicrobial agents.

4. Fabric Solutions

• Scouring: In cotton processing, ammonium carbonate helps remove natural waxes, oils, and impurities, improving the fabric's absorbency for subsequent treatments like dyeing.
• Wool Treatment: It modifies the scales on wool fibers, making them softer and enhancing their ability to absorb dyes.
• Silk Degumming: Ammonium carbonate helps remove sericin, the gummy protein coating silk fibers, resulting in a softer, drapier, and more lustrous silk.
• Mordanting: It's also used as a mordant, which helps dyes bind to the fabric, making the colors more permanent and vibrant.

5. Personal care

• pH Regulator and Buffer: Ammonium carbonate helps maintain the correct pH balance in cosmetic products, ensuring their stability and effectiveness. 
• Foaming Agent: In shampoos, hair dyes, and bath products, it acts as a foaming agent, creating a bubbly texture.
