1. Pharmaceuticals

• Antacid: Light magnesium carbonate is a common ingredient in over-the-counter medications for indigestion and heartburn. It works by neutralizing excess stomach acid, providing relief from associated symptoms.
• Pharmaceutical Excipient: In tablet formulations, light magnesium carbonate acts as a diluent (bulking agent), a disintegrant (helping the tablet break down), or a stabilizer (improving the tablet's stability).

2. Food & Healthcare Ingredients

• Anti-caking Agent: Light magnesium carbonate is added to powdered foods to prevent them from clumping together. This improves the flowability and ease of use of products like powdered milk, spices, sugar, and baking mixes. 
• Texturizer: In some food products, like cheese or chewing gum, light magnesium carbonate can act as a texturizer, improving mouthfeel and stability. 
• Nutritional Supplement: It's a source of magnesium, an essential mineral, and is added to nutritional and energy drinks to increase their magnesium content.

3. Personal Care

• Absorbent and Mattifying Agent: Light magnesium carbonate is known for its ability to absorb oil and perspiration, making it a popular ingredient in products like face powders, eyeshadows, and talcum powders. It helps create a smooth, matte finish on the skin, preventing shine and oiliness. This makes it suitable for use in products designed for oily or combination skin, as well as in products that need to control shine.
• Anti-Caking Agent: In powder-based products like dusting powders, dry shampoos, and sunscreens, light magnesium carbonate helps prevent clumping and caking, ensuring the product remains easily spreadable and functional. It helps maintain the free-flowing nature of the powder, preventing it from becoming a solid mass.

4. Paints, Coatings & Adhesives

• Pigment Carrier: Light magnesium carbonate acts as a carrier for pigments, helping them disperse evenly and stay suspended in the paint or coating medium. This improves the coloring power and brightness of the final product.
• Drying Agent: In some formulations, light magnesium carbonate can absorb moisture, aiding in the drying process of the paint or coating.

5. Polymers & Resins

• Flame Retardancy: Light magnesium carbonate is added to polymers like PVC and PE to enhance their fire resistance. When exposed to high temperatures, it decomposes, releasing carbon dioxide and water. This process absorbs heat and reduces the amount of flammable gases, making the material less likely to ignite and burn. 
• Smoke Suppression: The release of carbon dioxide during combustion also helps to suppress the amount of smoke produced, further enhancing the safety of materials used in construction, transportation, and electronics. 
• Reinforcing Agent: In some rubber applications, particularly with neoprene, light magnesium carbonate acts as a reinforcing agent, improving the material's tensile strength and overall durability.

6. Cleaning & Disinfectants

• Drying Agent: Light magnesium carbonate acts as a drying agent, absorbing moisture and preventing clumping in powders and other formulations. This is useful in cleaning products where keeping a dry, free-flowing texture is important. 
• Mild Abrasive: In toothpaste, it's used as a mild abrasive to help clean teeth and remove stains.
• Mild Abrasive: Light magnesium carbonate's fine particles provide a gentle scrubbing action, making it useful for cleaning surfaces without causing significant scratching or damage.

7. Pulp & Paper Solutions

• Filler: Light magnesium carbonate is incorporated into the pulp to improve various paper properties. It acts as a filler, replacing some of the cellulose fiber, which can reduce the overall cost of production. 
• Brightness and Whiteness: It enhances the brightness and whiteness of the paper, making it more appealing for printing and writing.
