According to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), dodecylamine polyoxyethylene ether AC-1205 (CAS: 26635-75-6) is classified as a low acute toxicity substance in terms of human health—the acute oral toxicity LD50 in rats is greater than 2000 mg\/kg, indicating a low acute toxicity risk from a single ingestion. However, this product is classified as Skin Irritation Category 2 (H315) and Serious Eye Damage\/Eye Irritation Category 2 (H319). Direct contact can cause skin redness, pain, and severe eye irritation symptoms. Therefore, personal protective measures must be taken during operation.
In terms of environmental impact, this product is classified as Hazardous to the Aquatic Environment — Long-term Chronic Hazard Category 3 (H412), meaning it is harmful to aquatic organisms with long-lasting effects. Specific ecotoxicity data show: the typical 96-hour LC50 for fish ranges from 1 to 10 mg\/L, and the typical EC50 for daphnia also ranges from 1 to 10 mg\/L. Furthermore, this product is not readily biodegradable in aquatic environments, exhibiting some persistence and potential for bioaccumulation. Therefore, it is strictly prohibited to directly discharge wastewater containing this product into sewers, surface water, or soil.
When handling this product, it is recommended to follow these protective measures:
| Toxicity Indicator | Data | Source |
|---|---|---|
| Acute Oral Toxicity (Rat) LD50 | >2000 mg\/kg | Guoli Chemical Product SDS |
| Skin Irritation\/Corrosion | Category 2 (H315: Causes skin irritation) | GHS Classification |
| Serious Eye Damage\/Eye Irritation | Category 2 (H319: Causes serious eye irritation) | GHS Classification |
| Fish Toxicity (96h LC50) | Typical range 1～10 mg\/L | Guoli Chemical Product SDS |
| Daphnia Toxicity (EC50) | Typical range 1～10 mg\/L | Guoli Chemical Product SDS |
| Biodegradability | Not readily biodegradable, with some persistence | Guoli Chemical Product SDS |
Currently, there is no specific antidote for this product; medical treatment should focus on symptomatic and supportive care. It is recommended to consult the complete Safety Data Sheet (SDS) before use for detailed information on storage, handling, and emergency response. In case of fire, combustion products may include toxic fumes such as carbon monoxide, carbon dioxide, and nitrogen oxides; firefighters must wear self-contained positive-pressure breathing apparatus.
