Material Safety Data Sheet
Cyclomethicone
Last Revised: 8/02/05
Extinguishing Media: Regular foam, carbon dioxide, dry chemical
Fire Fighting Procedures: Wear a self-contained breathing apparatus
with a full face piece operated in the positive pressure demand mode with
appropriate turn out gear and chemical resistant personal protection
equipment. Refer to the personal protective equipment section of this MSDS.
Fire and Explosion Hazards: Vapors are heavier than air and may
travel along the ground or be moved by ventilation and ignited by heat, pilot
lights, other flames and ignition sources at locations distant from material
handling point. Never use welding or cutting torch on or near drum (even
empty) because product (even just residue) can ignite explosively.
10. Toxicological Information
Acute Oral LD50: No data
Dermal and Eye Irritation Test: No data
Carcinogenicity: No data
Mutagenicity: No data
11. Disposal Considerations
Dispose of in accordance with all applicable local, state, and federal
regulations.
