Octadecylamine polyoxyethylene ether AC-1820 is classified under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) as skin irritation (Category 2, H315) and serious eye irritation (Category 2, H319), while also having acute toxicity to aquatic life (Category 3, H402). Its signal word is Warning, and the hazard pictogram is GHS07 (exclamation mark). This means that any negligence during operation may lead to discomfort such as redness, swelling, and pain at the contact site, so standardized use is key.
From the physicochemical properties of the product itself, AC-1820 is a non-ionic surfactant derived from octadecyl fatty amine as the starting material, modified by polymerization with ethylene oxide. Under acidic conditions, it can be protonated to exhibit cationic properties. Its good emulsifying and dispersing capabilities make it widely used in formulations, but it also means that if it leaks into water bodies, it may cause long-term harmful effects on the aquatic ecosystem. Therefore, it is strictly prohibited to discharge untreated material directly into water bodies or sewers.
In terms of daily operation management, enterprises should establish a comprehensive chemical management system. Operators must receive special training before starting work and be familiar with the Safety Data Sheet (SDS) of this product. The workplace should be equipped with emergency eyewash stations and safety showers, and ensure good ventilation, away from fire sources and strong oxidizers. Any unauthorized personnel must not enter the storage and usage areas.
| Protection Item | Specific Requirements |
|---|---|
| Hand Protection | Wear certified chemical safety protective gloves (nitrile rubber recommended), check glove integrity before each use |
| Eye/Face Protection | Wear chemical safety goggles or face shield to prevent splashes |
| Body Protection | Wear appropriate chemical protective clothing to avoid exposed skin |
| Respiratory Protection | Generally, no special respiratory protection is required, but ensure good ventilation in the work area; in environments with inadequate ventilation or where aerosols may be generated, use local exhaust ventilation or wear a particulate respirator |
| Operational Behavior | No eating, drinking, or smoking during operation; immediately remove contaminated clothing after operation, thoroughly wash hands and exposed skin |
| Accident Type | Handling Steps |
|---|---|
| Skin Contact | Immediately remove all contaminated clothing and thoroughly wash the affected area with plenty of running water and soap for at least 15 minutes. If skin irritation persists or worsens, seek medical attention immediately. |
| Eye Contact | Immediately rinse gently under eyelids with plenty of water or saline for at least 15 minutes. During rinsing, lift upper and lower eyelids occasionally. If wearing contact lenses and they can be easily removed, remove them and continue rinsing. Seek immediate professional medical treatment. |
| Inhalation | Quickly move the person to fresh air and maintain an open airway. If breathing discomfort occurs, administer oxygen. If breathing stops, immediately perform artificial respiration by trained personnel. Seek medical attention immediately. |
| Ingestion | Rinse mouth cautiously, do NOT induce vomiting to avoid aspiration into the lungs. Immediately call a poison control center or doctor, and show the product container or label. |
| Spill Handling | Personnel must wear appropriate personal protective equipment. Ensure safety first, then immediately contain and control the source of the spill. Cover and collect the spill with chemically inert absorbent materials (such as dry sand, vermiculite, or universal absorbent), and place in a sealed, labeled waste container. Do not flush spills into surface water, drainage systems, or soil. |
Dispose of waste as chemical waste in accordance with local, regional, and national environmental regulations. Recommended disposal methods include incineration in a licensed incinerator or handing over to a qualified professional waste disposal company. Do not discharge untreated material directly into the environment, sewers, or water bodies.
