Isooctanol penetrant OE-35 (CAS No: 68439-51-0) is a nonionic surfactant with isomeric alcohol polyoxyethylene ether as the active ingredient. According to its Safety Data Sheet under GHS classification (7th revised edition), this product is not classified as a hazardous substance. Under normal industrial use conditions, as long as basic safe operating practices are followed, this product does not pose a significant threat to human health.
In toxicological assessment, the product shows good safety: the acute oral LD50 in rats is greater than 5,000 mg/kg, indicating low toxicity; the primary skin irritation index is less than 0.5, meaning it is non-irritating to the skin; the guinea pig skin sensitization test shows no sensitization. The only point of caution is that the rabbit eye test shows mild irritation, but this irritation is fully reversible within 72 hours. Therefore, it is recommended to wear chemical safety goggles to prevent accidental splashes during operation.
In terms of the environment, the ecotoxicological data of isooctanol penetrant OE-35 are excellent: the 96-hour LC50 for fish is greater than 100 mg/L, indicating low toxicity to aquatic organisms. The OECD biodegradability test shows that the product has ready biodegradability and is not prone to persistent accumulation in the natural environment, meeting the core requirements of an environmentally friendly product.
| Assessment Item | Test Result | Conclusion |
|---|---|---|
| GHS Hazard Classification | Not classified as hazardous | Safe |
| Acute Oral Toxicity (Rat LD50) | > 5,000 mg/kg | Low toxicity |
| Skin Irritation | Primary Irritation Index < 0.5 | Non-irritating |
| Eye Irritation (Rabbit Eye) | Mild irritation, reversible in 72 h | Requires protection |
| Skin Sensitization (Guinea Pig) | No sensitization reaction | Safe |
| Aquatic Ecotoxicity (Fish 96h LC50) | > 100 mg/L | Low toxicity |
| Biodegradability (OECD) | Readily biodegradable | Environmentally friendly |
Given the low toxicity and low irritation properties of this product, it can be safely used in multiple fields such as textile printing and dyeing, leather chemicals, metal surface treatment, pesticide synergists, papermaking, and household chemical cleaning. When adding it to formulations, operators should still follow basic industrial hygiene practices to minimize any potential risks.
