Does OS-15 (AEO-15) cause harm to humans? Does it have an impact on the environment?

OS-15 (AEO-15) has mild to moderate irritation to humans under normal use conditions, but it has chronic toxicity to aquatic organisms, and emissions must be strictly controlled.

Detailed Description

OS-15 (AEO-15) is a non-ionic surfactant. According to the GHS classification system, its hazards to human health are mainly manifested in skin irritation (Category 2, H315) and serious eye irritation (Category 2, H319) . Toxicological data shows that the acute oral LD50 in rats is >2000 mg/kg, which is classified as low toxicity; the rabbit skin irritation index is <2, indicating mild irritation; the eye irritation score is moderate. Overall, the product is not carcinogenic, not mutagenic, has no reproductive toxicity, and is not explosive or flammable. Under standard operating conditions, its acute hazard to humans is relatively low.

In terms of environmental impact, OS-15 (AEO-15) is classified as Aquatic Chronic Toxicity Category 3 (H412) , meaning it has long-term adverse effects on aquatic organisms. Ecotoxicological data indicates: zebrafish 96h LC50: 1–10 mg/L, algae ErC50: 10–100 mg/L. Therefore, undiluted or large quantities of the product must not be discharged directly into water bodies, sewers, or the environment. Proper treatment must be carried out before discharge.

Application Recommendations

In industrial applications, the safety of OS-15 (AEO-15) is fully controllable, provided the following operating procedures are followed: Operators should receive specialized training, wear impermeable gloves (e.g., nitrile gloves) and chemical safety goggles; ensure good ventilation in the workplace to avoid inhaling vapors or mists; thoroughly wash hands and exposed skin after operation. In end-use consumer products such as cosmetics, ensure the formulation concentration complies with regulatory limits and complete necessary safety assessments.

Precautions

• Skin contact: Immediately remove contaminated clothing, rinse with plenty of running water and soap for at least 15 minutes; seek medical attention if irritation persists.


• Eye contact: Immediately lift eyelids, rinse with plenty of water or saline for 15–20 minutes, and seek immediate medical attention.


• Ingestion: Rinse mouth with water, do not induce vomiting, drink 1–2 glasses of water to dilute and seek medical attention as soon as possible.


• Spill treatment: For small spills, collect with inert materials such as sand; for large spills, construct dikes to contain and prevent entry into sewers or surface water bodies.


• Storage conditions: Cool, dry, well-ventilated, temperature maintained at 5–35°C, avoid freezing and excessive heat.


• Strictly prohibit direct discharge of untreated product into natural water bodies or the environment.
