MOA-12 (Lauryl alcohol polyoxyethylene ether-12) is a nonionic surfactant widely used in textiles, daily chemicals, pesticides, leather and other fields. According to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), this product is not classified as a hazardous substance, and its overall safety performance is good.
In terms of human safety, the acute oral toxicity (rat LD50 > 2000 mg/kg) and acute dermal toxicity (rabbit LD50 > 2000 mg/kg) are both at low toxicity levels; the Primary Irritation Index (PII) for skin is 0.0, meaning non-irritating to skin; it causes only mild, reversible eye irritation (Category 2B), which typically subsides within 24–48 hours; the skin sensitization test result is non-sensitizing. Therefore, under normal operating conditions, MOA-12 poses a very low health risk to humans, and no special skin protection is required during routine use.
Regarding environmental impact, an objective perspective is needed: MOA-12 is toxic to aquatic organisms (fish 96h LC50 1–10 mg/L), and direct large-scale discharge may cause short-term effects on aquatic ecosystems. However, it has excellent biodegradability (OECD 301 method, >60% degradation within 28 days), is easily and rapidly biodegradable, and has low bioaccumulation potential (Log Pow < 3), making it unlikely to accumulate in the food chain. Overall, as long as it is used and disposed of in strict accordance with regulations, its cumulative risk to the environment is controllable.
| Item | Data | Conclusion |
|---|---|---|
| Acute oral toxicity (rat) | LD50 > 2000 mg/kg | Low toxicity |
| Acute dermal toxicity (rabbit) | LD50 > 2000 mg/kg | Low toxicity |
| Skin irritation (rabbit) | PII = 0.0 | Non-irritating |
| Eye irritation (rabbit) | Mild conjunctival redness, subsides within 24–48 h | Mild reversible irritation |
| Skin sensitization (guinea pig) | Negative | Non-sensitizing |
| GHS Classification | Eye Irrit. 2B (H320) | Non-hazardous substance |
| Aquatic toxicity (fish 96h) | LC50 1–10 mg/L | Toxic to aquatic organisms |
| Biodegradability (OECD 301) | Degradation rate >60% in 28 days | Easily and rapidly biodegradable |
| Bioaccumulation potential | Log Pow < 3 | Low bioaccumulation |
In normal application scenarios such as textiles, daily chemicals, pesticides, and leather processing, the concentration and usage amount of MOA-12 are within safe ranges, and the risk to humans and the environment is controllable. Operators only need to follow basic industrial hygiene practices to ensure safety. This product is especially suitable for formulations with environmental requirements, as its easy biodegradability aligns with the trend of green chemistry and sustainable development.
