Polyglutamic Acid CAS 25513-46-6

1. Polyglutamic acid is a biodegradable, water-soluble polymer primarily used in the cosmetic industry as a superior moisturizing agent due to its exceptional water-holding capacity, often outperforming hyaluronic acid .
2. Polyglutamic acid CAS 25513-46-6 serves as a versatile biomaterial in drug delivery systems for the controlled release of therapeutics, particularly in cancer research where its biocompatible and non-immunogenic properties are valued .
3. Polyglutamic acid is utilized in the food industry as a natural preservative, thickening agent, and as a cryoprotectant to improve the texture and shelf life of frozen and processed foods .
4. In agriculture, researchers use Polyglutamic acid CAS 25513-46-6 as a soil conditioner and plant growth promoter to enhance nutrient absorption, water retention, and stress tolerance in crops .

1. Polyglutamic acid must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture .
2. Polyglutamic acid CAS 25513-46-6 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 Polyglutamic acid is released .
2. Collect Polyglutamic acid CAS 25513-46-6 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. Polyglutamic acid is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) .
2. Use Polyglutamic acid CAS 25513-46-6 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 Polyglutamic acid 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 .
