Cocamide DEA is a nonionic surfactant produced by condensing coconut oil with diethanolamine. Although widely used, its safety cannot be overlooked. Under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), this product is classified as Skin corrosion\/irritation Category 2 (H315: Causes skin irritation), Serious eye damage\/eye irritation Category 2 (H319: Causes serious eye irritation), and Carcinogenicity Category 2 (H351: Suspected of causing cancer). The International Agency for Research on Cancer (IARC) classifies it as Group 2B. The core risk is that residual diethanolamine in the product may form nitrosamine precursors, and nitrosamines are confirmed to have potential carcinogenicity.
During routine operations, the workplace must maintain good ventilation, and local exhaust ventilation should be installed if necessary to prevent vapor accumulation. Operators should receive professional training and be familiar with the product's hazards and protective measures. Full personal protective equipment, including protective gloves, protective clothing, safety goggles, and face shields (P280), must be worn throughout the operation. After operation, thoroughly wash hands and exposed areas (P264). Eating, drinking, and smoking are prohibited during operation. Close the container promptly after use and avoid contact with incompatible substances such as strong oxidizers.
| Hazard Category | GHS Classification | Hazard Code | Description |
|---|---|---|---|
| Skin corrosion\/irritation | Category 2 | H315 | Causes skin irritation |
| Serious eye damage\/eye irritation | Category 2 | H319 | Causes serious eye irritation |
| Carcinogenicity | Category 2 (IARC 2B) | H351 | Suspected of causing cancer; contains residual diethanolamine that may form nitrosamine precursors |
| Storage Temperature | Recommended 10–40°C; avoid high temperatures and freezing to prevent product deterioration or separation | ||
| Flammability | Combustible but not flammable; may release toxic gases such as nitrogen oxides and carbon monoxide when exposed to fire | ||
Skin contact: Immediately remove contaminated clothing and rinse skin thoroughly with plenty of water and soap for at least 15 minutes. If irritation occurs, seek medical attention (P302+P352).
Eye contact: Immediately lift eyelids and rinse gently with plenty of running water or saline solution for at least 15 minutes, keeping eyes open. If irritation persists, seek medical attention immediately (P305+P351+P338).
Inhalation: Move the person to fresh air immediately and keep the airway unobstructed. If breathing is difficult, administer oxygen; if breathing stops, perform artificial respiration immediately and seek medical help.
Ingestion: Do not induce vomiting. Rinse mouth with water and seek medical attention immediately. If any contact is suspected, seek medical attention immediately (P308+P313).
Spill disposal: Quickly evacuate personnel from the spill area to a safe zone and prevent unauthorized personnel from entering. For small spills, use inert absorbent materials (e.g., sand, vermiculite) to collect and place in a dedicated container; for large spills, construct dikes to contain, and transfer using explosion-proof pumps to a dedicated collector. Collect washing water for treatment; do not discharge directly into drains, water bodies, or soil.
Fire disposal: Suitable extinguishing media include alcohol-resistant foam, dry powder, carbon dioxide, and water spray. Firefighters must wear self-contained positive-pressure breathing apparatus and full-body fire and chemical protective clothing. Fight fire from a safe distance and use water spray to cool containers exposed to fire to prevent pressure buildup and explosion.
