According to the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), Peregal O-50/100 (fatty alcohol polyoxyethylene ether) does not belong to physical hazard categories and is not classified as a hazardous chemical requiring mandatory warnings. This product is synthesized by addition polymerization of natural fatty alcohols (C₁₆~C₁₈) with ethylene oxide. The raw materials are of natural origin, and the molecular structure determines its excellent performance in safety and environmental protection.
In terms of human health, the acute oral toxicity of Peregal O-50/100 is very low (LD50 > 2000 mg/kg, rat), falling under GHS acute toxicity category 5 or unclassified, roughly equivalent to the toxicity level of daily household cleaning products. This product has no skin corrosion, no serious eye damage, and no respiratory or skin sensitization, posing no significant health risks to humans under normal industrial use conditions. Only prolonged contact at high concentrations may cause slight skin dryness or discomfort, which is related to the defatting properties of the surfactant rather than chemical irritation.
In terms of environmental impact, Peregal O-50/100 has low aquatic toxicity (EC50/LC50 > 100 mg/L) and is not classified as an acute aquatic toxicity category. The ether bonds and linear alkyl groups in its molecular structure are easily degraded by microorganisms in nature, showing excellent biodegradability, and do not persist or accumulate in the environment, meeting the environmental requirements of modern green chemistry and sustainable development.
| Assessment Item | Result | Remarks |
|---|---|---|
| Acute Oral Toxicity | Low toxicity (LD50 > 2000 mg/kg, rat) | GHS Category 5 or unclassified |
| Skin Corrosion/Irritation | None | Prolonged high-concentration contact may cause slight irritation |
| Serious Eye Damage/Irritation | None | May cause slight discomfort |
| Respiratory/Skin Sensitization | None | No reports of sensitization |
| Aquatic Toxicity | Low (EC50/LC50 > 100 mg/L) | Not classified as acute aquatic toxicity category |
| Biodegradability | Excellent | Easily degraded by microorganisms |
| Flammability | Non-flammable | May decompose at high temperatures to produce irritating fumes |
Based on its excellent safety characteristics, Peregal O-50/100 can be safely used in various industrial fields: textile printing and dyeing auxiliaries, cosmetic creams and lotions, pesticide formulations, paper deinking agents, etc. Especially in consumer product formulations with indirect human contact (such as textile softeners, conditioners, and moisturizing creams), it can also be used safely, an advantage not possessed by many industrial surfactants.
Conclusion: Peregal O-50/100 is a well-validated, low-toxicity, low-irritation, eco-friendly non-ionic surfactant. With compliance to basic industrial hygiene practices, the risks to both human health and the environment are at a low level, making it suitable for safe use in modern industrial formulations that emphasize safety and sustainable development.
