Ventilation:
Provide effective general ventilation during routine transfer and formulation.
Use local exhaust when the material is sprayed, heated, or handled in open high-shear equipment.
Storage:
Store in tightly closed compatible containers in a cool, dry, and well-ventilated area.
Keep away from strong oxidizing agents, excessive heat, flames, sparks, and contamination.
Spill and Leak Procedures:
Stop the leak when this can be done safely and contain the liquid with inert absorbent material.
Prevent uncontrolled entry into drains, soil, and surface water.
Fire Precautions:
Use foam, dry chemical, carbon dioxide, or water fog as appropriate to the surrounding fire and supplier SDS.
Wear suitable respiratory protection where smoke or thermal-decomposition products may be present.
Handling Precautions:
Do not assume that technical, food, pharmaceutical, cosmetic, and analytical grades are interchangeable.
Confirm assay, acidity, water, color, residual alcohols, migration suitability, and regulatory documentation before use.
Follow the current specification, certificate of analysis, regional safety data sheet, and applicable food-contact, pharmaceutical, cosmetic, and chemical regulations.
