Fire/Explosion Hazards: Not flammable, no unusual hazards, may produce toxic fumes when overheated (carbon oxides, nitrogen oxides, hydrogen chloride)
Special Protective Equipment: Firefighters wear self-contained breathing apparatus, protective clothing
Other Advice: Prevent contaminated runoff from entering waterways, cool containers exposed to flames with water spray
Personal Precautions: Wear protective equipment (gloves, goggles), avoid skin and eye contact
Environmental Precautions: Prevent entry into sewers, drains, surface water or soil, report large spills under local regulations
Cleanup Methods: Contain spill with absorbent (sand, soil, commercial absorbent), shovel into containers, wash area with water
Methods for Disposal: Dispose of material according to local regulations being careful to prevent environmental contamination
Handling: Avoid eye/skin contact, ensure ventilation, wear suitable protection
Hygiene Practices: Wash hands after use, no eating, drinking, or smoking near product
Storage Conditions: Store in tightly closed containers, cool, dry, well-ventilated area away from direct sunlight, avoid freezing
Incompatibilities: Strong oxidizers reduce stability, acids or bases may cause destabilization
Special Requirements: Use only containers and equipment resistant to polymer, keep away from foodstuffs
Occupational Exposure Limits: No specific limits established for Polyquaternium-7
Engineering Controls: Use local exhaust/ventilation in case of vapor formation or large scale use
Personal Protection: Protective gloves (PVC, nitrile), safety glasses or goggles, protective work clothing
Respiratory Protection: Not needed under normal conditions, use mask for mist or aerosol
Environmental Exposure: Avoid release to water systems, collect and dispose spills promptly
Appearance: Clear to slightly hazy, colorless to pale yellow viscous liquid
Odor: Slight, non-descript
pH: 5.0 – 7.5 (10% solution)
Melting/Freezing Point: Not applicable/approx. 0°C (solution)

Acute Toxicity: Lowest expected oral LD50 in rats: greater than 2000 mg/kg
Skin Contact: Minimal effects, possible irritation for sensitive individuals
Eye Contact: May cause mild irritation or redness
Repeated Dose Toxicity: Not expected to be toxic, no evidence of chronic exposure risks published
Carcinogenicity: No component listed by IARC, NTP, or OSHA
Mutagenicity: No adverse data available
Reproductive Toxicity: No reproductive risk identified
Additional Information: Not classified as hazardous for health under normal use
Aquatic Toxicity: Low toxicity expected, no acute effects at normal concentrations, large spill may alter water quality
Persistence and Degradability: Polymer backbone not readily biodegradable, may adsorb to sludge
Bioaccumulative Potential: Not expected
Mobility in Soil: Mobile in water, may bind to soil
Other Effects: Commercial grades are environmentally moderate, some components (traces of acrylamide, DMDAAC) require attention for aquatic discharge
