Magnesium Carbonate CAS 546-93-0

1. Magnesium carbonate is primarily used as an anti-caking agent and drying agent in food products, pharmaceuticals, and cosmetics, where it absorbs moisture and improves powder flowability .
2. Magnesium carbonate CAS 546-93-0 serves as a dietary supplement to provide magnesium, which is essential for bone health, muscle function, and metabolic processes .
3. Magnesium carbonate is employed as a filler and reinforcing agent in rubber, plastics, and coatings, enhancing mechanical properties and surface finish .
4. In personal care products, magnesium carbonate is used as an absorbent, opacifying agent, and as a component in athletic chalk to improve grip and reduce moisture .

1. Magnesium carbonate must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from moisture and carbon dioxide .
2. Magnesium carbonate CAS 546-93-0 is classified as non-hazardous under normal handling conditions according to GHS criteria, but may cause mild skin, eye, and respiratory tract irritation .
3. Personnel should wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, avoiding formation of dust and aerosols .
4. Keep Magnesium carbonate CAS 546-93-0 away from incompatible materials such as strong acids and strong oxidizing agents; magnesium carbonate is stable under recommended storage conditions .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when Magnesium carbonate is released .
2. Collect Magnesium carbonate CAS 546-93-0 by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses .
4. Dispose of collected material according to local, state, and federal environmental regulations; the substance is considered non-hazardous for transport (DOT, IATA, IMDG) .

1. Magnesium carbonate is not classified as highly flammable and does not burn under normal fire conditions; however, it may decompose when heated to high temperatures .
2. Use Magnesium carbonate CAS 546-93-0 water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving surrounding materials .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Magnesium carbonate due to potential exposure to decomposition products .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
