Special Remarks on other Toxic Effects on Humans:
Acute Potential Health Effects:
Skin: May cause skin irritation. However, brief contact is not known to be irritating.
Eyes: Causes severe eye irritation and conjunctivitis with possible chemical burns of the eye. Ingestion: may cause abdominal discomfort, nausea, vomiting, and diarrhoea. Aspiration into the lungs may occur during ingestion or vomiting, resulting in lung injury. May affect behaviour (somnolence, tremor), respiratory system (acute pulmonary enema), metabolism and liver.
Inhalation: Mist may cause irritation of the respiratory tract experienced as nasal discomfort and discharge with chest pain and coughing. May affect respiration experienced as audible respiration, and mouth breathing, and distended abdomen. Exposure to high aerosol concentrations for a prolonged period of time may result in suffocation.
Chronic Potential Health Effects: Skin: Prolonged or repeated skin contact may cause irritation and dermatitis. Prolonged or widespread contact may result in absorption of potentially harmful amounts and may cause abdominal discomfort, nausea, vomiting, and diarrhoea. Ingestion: Prolonged or repeated ingestion may affect the liver and metabolism. Animal studies also indicate that continuous exposure to high concentrations may be toxic to the kidneys.
12: Ecological Information
Ecotoxicity: Ecotoxicity in water (LC50): 21.4 mg/l 48 hours [Daphnia]. 6.6 mg/l 96 hours [Daphnia]. 7.7 mg/l 96 hours [Fish (Fathead Minnow)]. 4.8 mg/l 96 hours [Fish (Fathead Minnow)]. 6.6 mg/l 96 hours [Fish (Fathead Minnow)].
BOD5 and COD: Not available.
Products of Biodegradation:
Possibly hazardous short-term degradation products are not likely. However, long term degradation products may arise.
Toxicity of the Products of Biodegradation: The products of degradation are less toxic than the product itself.
Special Remarks on the Products of Biodegradation: Avoid discharge into natural waters. Microbial degradation results in some intermediates that have shown weak estrogen memetic activity. These effects have been observed in laboratory studies only at concentrations of these degradation intermediates greater than those required for eliciting conventional toxicity in the most sensitive aquatic organisms (approx. 5 ppm). Therefore, conventional toxicity remains the more sensitive indicator of environmental exposure to degradation of intermediates of NPES.
13: Disposal Considerations
Waste Disposal: For disposal of aqueous surfactant solutions: Aerobic biological wastewater treatment systems are effective in treating aqueous solutions of surfactants. Removal efficiency will depend upon treatment plant conditions. As with any waste water, consultation with local treatment plant staff is recommended (and required by law). Before disposal, in activated sludge treatment systems, inlet concentrations below 5 mg/l have been treated without foaming problems. For disposal of neat unused surfactant: Incinerate in a furnace where permitted under federal, state and local regulations. Surfactants can cause foaming problems in biological treatment plants and other high shear operations. For disposal of neat, unused surfactant, incinerate in a furnace where permitted under Federal, State, and Local regulations. Dispose in accordance with applicable Federal, State, and Local environmental regulations. Empty containers should be recycled or disposed of through an approved waste management facility.
