Pingpingjia O-15 (fatty alcohol polyoxyethylene (15) ether) has low acute toxicity, with an oral LD50 value greater than 2000 mg/kg in rats, classified as a low-toxicity substance according to chemical classification standards. However, this product is not completely harmless — it is classified as a skin irritant (Category 2) and a serious eye irritant (Category 2A). Direct skin contact may cause moderate irritation, redness or discomfort; if splashed into eyes, it can cause severe irritation, requiring immediate continuous rinsing with running water for at least 15 minutes and prompt medical attention.
When handling Pingpingjia O-15, always wear protective gloves, protective clothing and eye protection, and operate in a well-ventilated area. After operation, thoroughly wash exposed skin. In case of accidental contact during use, for skin contact, immediately wash thoroughly with soap and water; for eye contact, separate eyelids, remove contact lenses if present, continue rinsing and seek medical attention. Do not store the product with incompatible materials such as strong oxidizers, strong acids, strong bases, etc.
Pingpingjia O-15 is classified as Aquatic Hazard Category 3 (Chronic) under GHS, with hazard statement H412 — "Harmful to aquatic life with long lasting effects". This means that once released into environmental waters, it may cause chronic harm to aquatic organisms such as fish and daphnia, and is not readily biodegradable, with effects lasting for a long time.
| Ecotoxicity Indicator | Test Organism | Test Duration | Data |
|---|---|---|---|
| LC50 | Fish | 96 hours | ＞100 mg/L |
| EC50 | Daphnia | 48 hours | ＞100 mg/L |
As can be seen from the table above, the acute toxicity of Pingpingjia O-15 to aquatic organisms is relatively low (all greater than 100 mg/L), but its environmental risk mainly comes from the cumulative effect of long-term continuous exposure. Therefore, during use and disposal, strict measures must be taken to prevent the product from entering sewers, surface water or groundwater. Spills should be collected with inert absorbent materials such as sand, vermiculite, placed in dedicated containers and disposed of according to national/local regulations.
When using Pingpingjia O-15 in industries such as textile printing and dyeing, industrial cleaning, daily chemicals, pesticide formulations, etc., it is recommended that enterprises establish a sound environmental management system. Production wastewater should be fully treated by a sewage treatment system to meet standards before discharge. In formulation design, consider compounding with other environmentally friendly surfactants to reduce the overall environmental load while ensuring performance.
