| Detergency | Excellent soil-removing capacity, especially for oil, grease, and particulate dirt |
| Chemical Reactivity | - Reacts with bases to form salts (e.g., sodium dodecylbenzenesulfonate, SDBS)- Undergoes esterification, amidation reactions- Non-flammable, non-explosive- Compatible with nonionic, amphoteric surfactants; incompatible with cationic surfactants |
| Thermal Stability | Stable at room temperature; decomposes at > 200°C (releases SO? gas) |
Dodecylbenzenesulfonic Acid (LAS) is one of the most widely used anionic surfactants, primarily applied in:
| Item | Requirements |
|---|---|
| Packaging | 200 kg HDPE plastic drums; 1000 kg IBC tanks; bulk tankers (for large orders) |
| Storage Conditions | - Store in cool, dry, well-ventilated area; avoid direct sunlight and extreme temperatures (5–35°C).- Keep sealed tightly to prevent moisture absorption and contamination.- Avoid contact with strong bases, oxidizing agents, and cationic surfactants.- Do not stack drums higher than 3 layers to prevent leakage. |
| Shelf Life | 12 months from production date (when stored properly) |
| Handling Notes | - Use forklift with drum clamp for loading/unloading; avoid dropping or collision.- Wear protective equipment (acid-resistant gloves, goggles, apron, and face shield) during handling (due to acidic corrosivity).- Rinse immediately with water if spilled on skin or eyes. |
| Hazard Classification | Details |
|---|---|
| Physical Hazards | None (non-flammable, non-explosive) |
| Health Hazards | - Skin Corrosion/Irritation (Category 1): Causes severe skin burns and irritation.- Eye Damage (Category 1): Causes irreversible eye damage and corneal burns.- Inhalation Irritation: May cause respiratory tract irritation if exposed to mist/vapor. |
| Environmental Hazards | Low aquatic toxicity; readily biodegradable, no long-term environmental impact. |
