First Aid Measures

Eye Contact: Rinse gently and thoroughly with water for at least 15 minutes; lift eyelids to ensure complete flushing. Remove contact lenses if present and easy to do, continue rinsing. Seek medical attention if redness or irritation develops.
Skin Contact: Remove contaminated clothing and rinse skin with soap and plenty of water. If irritation persists, consult a physician. Wash clothing before reuse.
Inhalation: Move person to fresh air. If symptoms such as headache, dizziness, or respiratory discomfort develop, seek medical attention. Perform artificial respiration if breathing stops.
Ingestion: Rinse mouth, give water to dilute but do not induce vomiting. Contact a medical professional or Poison Control Center immediately.

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry powder, foam, carbon dioxide
Unsuitable Extinguishing Media: Direct water jet on spillage
Hazards from Combustion: May produce toxic fumes of carbon monoxide, carbon dioxide, and organic vapors
Special Equipment: Firefighters should use self-contained breathing apparatus and protective clothing
Fire-Fighting Techniques: Use water spray to cool fire-exposed containers; contain runoff to prevent environmental contamination

Accidental Release Measures

Personal Precautions: Avoid breathing vapors or mist. Wear impervious gloves, safety goggles, and protective clothing. Remove all ignition sources.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not discharge into drains, surface water, or soil.
Methods for Clean-up: Absorb spill with inert material like sand or vermiculite. Collect material in appropriate waste container. Wash area with detergent and water after clean-up.

Handling and Storage

Handling: Keep container tightly closed when not in use. Avoid release to the environment. Use only with adequate ventilation. Do not eat, drink, or smoke while using.
Storage: Store between 5°C and 30°C. Keep away from incompatible materials such as strong oxidizers and acids. Store in original, clearly labeled containers. Avoid freezing or excessive heat.

Exposure Controls and Personal Protection

Exposure Limits: Dipropylene glycol methyl ether OSHA PEL: 100 ppm, ACGIH TLV: 100 ppm
Engineering Controls: Local exhaust ventilation, eye wash stations, safety showers
Personal Protection: Chemical-resistant gloves (nitrile or neoprene), splash-proof safety goggles or face shield, long-sleeved clothing, and apron
Respiratory Protection: Use NIOSH-approved particulate respirator if exposure limits are exceeded or if irritating mists are generated

Toxicological Information

Acute Effects: Contact with eyes causes significant irritation. Prolonged or repeated skin contact may cause dermatitis. Inhalation of mist may irritate upper respiratory tract and cause headache or dizziness.
Chronic Effects: Not classified as carcinogenic, mutagenic, or toxic for reproduction. Skin sensitization may occur for those with existing conditions or allergies.
LD50 Oral (Rat): >5,000 mg/kg (alkoxylated fatty alcohols)
LD50 Dermal (Rabbit): >2,000 mg/kg
Inhalation LC50: Not established for mixture; components above 20 mg/L are not expected to create acute toxicity at workplace concentrations

Ecological Information

Aquatic Toxicity: Fish LC50 (96h): 10-100 mg/L (moderately toxic to aquatic organisms) for primary surfactant components
Persistence and Degradability: Product is biodegradable; surfactants meet OECD criteria for biodegradation; minor ingredients may persist longer
Bioaccumulation: Not expected due to low log Kow values
Mobility in Soil: Product is moderately mobile, with potential leaching if large spills occur
Other Adverse Effects: Do not discharge into surface waters or municipal sewers

Disposal Considerations

Waste Disposal: Dispose of in accordance with local, regional, and national regulations. Consult an approved waste disposal operator for bulk waste.
Container Handling: Triple rinse containers before recycling or disposal. Do not reuse empty packaging.
