Question

Is tristyrylphenol polyoxyethylene ether 600-1 harmful to humans? Does it have an impact on the environment?

Answer

Tristyrylphenol polyoxyethylene ether 600-1 is a low-toxicity, low-irritation, readily biodegradable non-hazardous substance, which is relatively friendly to human health and the environment, with high safety under normal use conditions.

Detailed Explanation

Tristyrylphenol polyoxyethylene ether 600-1 (agricultural emulsifier 600#-1) is classified as not a hazardous substance according to GB/T 16483 standard. Under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), this product does not belong to physical hazard, health hazard or environmental hazard categories. Overall, it is a non-ionic surfactant with high safety, and under standard industrial operating conditions, it will not pose significant harm to humans.

In terms of the environment, this product exhibits good ecological compatibility. According to OECD 301B standard testing, the 28-day biodegradation rate is greater than 60%, making it a readily biodegradable substance. Meanwhile, toxicity data for aquatic organisms show that the 96-hour LC50 for zebrafish, 48-hour EC50 for Daphnia magna, and 72-hour ErC50 for algae are all greater than 100 mg/L, indicating low acute toxicity to aquatic ecosystems. Under the premise of following waste disposal regulations, this product will not cause persistent pollution to the environment.

Toxicological and Ecotoxicological Parameters

ItemData/Conclusion
Hazard classificationNon-hazardous
Acute toxicity (rat oral LD50)>5000 mg/kg (low toxicity)
Skin irritation (rabbit)Non-irritating (Primary Irritation Index 0.0)

Skin sensitization (guinea pig)Negative, no sensitization
Zebrafish 96h LC50>100 mg/L
Daphnia magna 48h EC50>100 mg/L
Algae 72h ErC50>100 mg/L
Biodegradability (OECD 301B, 28 days)>60%, readily biodegradable

Safe Use Recommendations

Personal protection: Although skin irritation and sensitization are negative, it is still recommended to wear conventional chemical gloves and protective goggles when handling, and wear long-sleeved work clothes to avoid prolonged and repeated skin contact. This product has no special respiratory protection requirements, but the workplace should be well ventilated.

Eye protection must be emphasized: This product is mildly irritating to the eyes. If accidentally splashed into the eyes, immediately rinse with plenty of running water or saline solution for at least 15 minutes, do not rub the eyes, and remove contact lenses if worn. If irritation persists after rinsing, seek medical attention promptly.

Environmental management: Although this product is a readily biodegradable substance, it is strictly prohibited to discharge directly into sewers, surface water, or soil during waste disposal. It should be collected and handed over to a qualified professional waste treatment facility for incineration or other approved methods, in compliance with national and local environmental regulations.

Precautions

  • Store in a sealed, cool, dry, and well-ventilated place, away from strong oxidizers and strong acids.
  • If accidentally ingested, rinse mouth with clean water immediately, do not induce vomiting, and bring the product label to seek medical attention promptly.
  • In case of large spill, build dikes to prevent spreading, and collect with inert absorbent materials for disposal.
  • Although the product is relatively safe, basic chemical handling procedures should still be followed, and eating or smoking is prohibited during work.
