Xanthan Gum CAS 11138-66-2

1. Xanthan gum is a polysaccharide produced by bacterial fermentation, primarily used as a thickening agent, stabilizer, and emulsifier in the food industry for products such as salad dressings, sauces, dairy products, and gluten-free baked goods .
2. Xanthan gum CAS 11138-66-2 serves as a rheology modifier in personal care and cosmetic formulations, including lotions, creams, shampoos, and toothpaste, providing enhanced texture, suspension stability, and controlled flow properties .
3. Xanthan gum is utilized in pharmaceutical formulations as a suspending agent, matrix former for controlled release tablets, and as a stabilizer in liquid oral preparations and topical gels .
4. In industrial applications, Xanthan gum CAS 11138-66-2 is used in oil drilling fluids, agricultural sprays, and as a stabilizer in paints and coatings due to its pseudoplastic rheological properties and stability over a wide range of pH and temperatures .

1. Xanthan gum must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture to prevent caking and degradation .
2. Xanthan gum CAS 11138-66-2 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 away from incompatible materials such as strong oxidizing agents; the compound is hygroscopic and should be stored in a tightly sealed container to prevent moisture absorption .

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 Xanthan gum is released .
2. Collect Xanthan gum CAS 11138-66-2 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. Xanthan gum is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide and carbon dioxide .
2. Use Xanthan gum CAS 11138-66-2 water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Xanthan gum due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
