Isotridecanol ethoxylate E-1303 (CAS No.: 9043-30-5) is a nonionic surfactant derived from isotridecyl alcohol through ethoxylation. According to GHS classification criteria, this product is classified as Skin irritant Category 2 (H315) and Serious eye damage/eye irritant Category 2A (H319), with a hazard level of "Warning." Acute oral toxicity (rat LD50) is greater than 2000 mg/kg, falling into the low toxicity range, but safe operating procedures must still be strictly followed during use.
This product has excellent chemical stability and remains active in a wide range of acidic, alkaline, and hard water environments. However, contact with strong oxidizers, strong acids, or strong bases may cause dangerous reactions; therefore, mixing with such substances should be avoided during storage and use. The product is not flammable, but thermal decomposition may produce harmful gases, so it should be kept away from fire and heat sources.
From an ecological safety perspective, this product has low toxicity to aquatic organisms (fish LC50, algae EC50, and daphnia EC50 are all greater than 100 mg/L) and is an easily biodegradable surfactant (certified by OECD 301 method, with BOD/COD ≥ 60% or DOC removal rate ≥ 70%). However, direct discharge into sewers, surface water, or soil is still prohibited.
| Protection Area | Protective Measures |
|---|---|
| Eyes | Wear chemical safety goggles; do not wear contact lenses during operation |
| Hands | Wear impervious gloves, recommended nitrile rubber or chloroprene rubber |
| Body | Wear appropriate protective clothing to avoid direct skin contact |
| Respiratory system | Operate in well-ventilated areas; use local exhaust ventilation if necessary to avoid inhaling vapors or mists |
| Operating environment | Use explosion-proof equipment to avoid generation and accumulation of static electricity; eating, drinking, and smoking are prohibited in the workplace |
| Storage Parameter | Requirement |
|---|---|
| Temperature | Recommended 5 °C to 40 °C; avoid freezing or high temperature exposure |
| Environment | Cool, dry, well-ventilated dedicated warehouse, away from fire and heat sources |
| Container | Keep tightly closed to prevent leakage and moisture absorption; reseal immediately after use |
| Segregation requirements | Store separately from strong oxidizers, strong acids, strong bases, and food-grade chemicals; do not mix storage |
| Inspection and maintenance | Regularly check packaging integrity; replace or transfer to intact containers if damage is found |
Skin contact: Immediately remove contaminated clothing and flush thoroughly with plenty of running water and soap for at least 15 minutes. If irritation persists, seek medical attention immediately.
Eye contact: Immediately lift eyelids and flush thoroughly with plenty of running water or saline solution for at least 15 minutes. If contact lenses are present and easily removable, remove them and continue flushing. If eye irritation persists, seek medical attention.
Inhalation: Move quickly to fresh air and maintain an open airway. If breathing is difficult, give oxygen; if breathing or heartbeat stops, perform CPR immediately and seek medical attention.
Ingestion: Rinse mouth with water; do NOT induce vomiting; seek medical attention immediately. Do NOT give anything by mouth to an unconscious person.
Spill response: Isolate the spill area, restrict access, and eliminate all ignition sources. For small spills, absorb with inert absorbent materials (e.g., sand, vermiculite) and collect in a closed container; for large spills, construct dikes or pits for containment and transfer using explosion-proof pumps to dedicated collection containers.
