IV. EMERGENCY AND FIRST AID PROCEDURES EYES: In case of contact, immediately flush with plenty of low pressure water for at least 15 minutes. Remove any contact lenses to assure thorough flushing. Call a physician. Remove to fresh air. Treat any irritation symptomatically. Call a physician. V. FLAMMABILITY INFORMATION Caution: Flammable dust when finely divided and suspended in air. Surfaces subject to spills or dusting can become slippery when wet. Browning temperature: 227 C (440 F) Flammable limits: N/A Autoignition temperature: >370 C (698 F) as dust. Extinguishing media: Water spray, dry chemical, foam or carbon dioxide. Special fire-fighting procedures: None. Unusual fire and/or explosion hazards: Flammable dust when finely divided and suspended in air. Combustion products include: Carbon monoxide, carbon dioxide and smoke. VI. SPILL & LEAK PROCEDURES STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: Sweep up spilled material for use or disposal. Surfaces subject to spills or dusting with this product can become slippery when wet. Waster Disposal Method: Incineration of waste material in a permitted facility in accordance to local, state, and federal regulations is the recommended disposal method. Landfilling in a licensed facility equipped with leachate collection is a suitable alternative. This product is biodegradable. Wastewater containing this product can be considered for treatment in an acclimated biological treatment system of adequate capacity. This product is not listed in federal hazardous waste regulations 40CFR261.33 paragraphs (e) or (f), i.e. chemical products that are considered hazardous if they become wastes. It does not exhibit any of the hazardous characteristics listed in 40CFR261 Subpart C. State or local hazardous waste regulations may apply if different from the federal. VII. HANDLING AND STORAGE PROCEDURES Keep away from heat, sparks and open flame. To protect product quality, store in sealed containers in a dry and well ventilated area, away from heat and sunlight. VIII. EXPOSURE LIMITS / INDIVIDUAL PROTECTION Not established. This material is not expected to cause physiologic impairment at low concentration. Until a specific TLV is adopted by the ACGIH (American Conference of Governmental Industrial Hygienists), or an OSHA (Occupational Safety & Health Administration) standard is issued, Quimica Amtex S.A. suggests that this material be treated as a nuisance dust or particulate in accordance with the recommendations of ACGIH.

Not listed as a carcinogen by NTP (National Toxicology Program); not regulated as a carcinogen by OSHA (Occupational Safety & Health Administration); not evaluated by IARC (International Agency for Research on Cancer). Reported Human Effects: A single case of allergic contact dermatitis reported after repeated long-term (8 years) skin contact with purified sodium CMC. Reported Animal Effects: Eye irritation after exposure to dust of purified sodium CMC. Laboratory studies indicate that SODIUM CARBOXYMETHYLCELLULOSE is not a mutagen, not a teratogen, not a carcinogen and does not cause effects on reproduction. XII. ECOLOGICAL INFORMATION. Eco-toxicological analysis performed with identical chemicals had the following results: Acute toxicity for fish: Clo > 2000 mg / l Species: Brachynadio rerio Acute toxicity for fish: CL100: > 4000 mg / l Species: Brachynadio rerio (OCDE guidelines for chemical tests, N° 203) Acute toxicity for bacteria: CE50: 10,000 mg / l (OCDE guidelines for chemical tests, N° 209) Bio-accumulation: log POW < 0 - not lipophil, with no bio-accumulation potential. Degradability: Biological degradation: < 5% after 28 days.
