Main application
- Neutralization and preparation of sodium dodecylbenzenesulfonate (SDBS) for daily chemical washing (maximum use): core raw materials for laundry powder, laundry detergent, dishwashing detergent, and industrial cleaning agents;
Can neutralize into ammonium salts and triethanolamine salts, used for shampoo and hard surface cleaning agents.
- Industrial cleaning agents are directly formulated with acidic degreasers, bathroom cleaners, and metal pickling degreasers; Resistant to hard water and has excellent cleaning power in acidic environments.
- Additive industry
Textile: refining agent, leveling agent, penetrating agent;
Coatings/resins: amino baking paint acid curing catalyst;
Pesticides: pesticide emulsion emulsifiers;
Wetting and dispersing agents for electroplating and leather processing.
- Organic synthesis of acidic catalysts and reaction media.
Key points of safety and storage and transportation
- Corrosive liquids can burn the skin, eyes, and respiratory tract. Protective goggles and acid and alkali resistant gloves must be worn during operation;- It is strictly prohibited to mix with strong alkalis and oxidants; Dilution operation: Slowly add acid to water, do not pour water into the original solution to prevent boiling and splashing;
- Packaging: Storage and transportation in 210L plastic drums; Store in a cool, ventilated and sealed manner;
- Hazardous chemical classification: Belongs to corrosive hazardous materials.
Supplementary differentiation
- LABSA (27176-87-0) straight chain: easily biodegradable, mainstream household detergent;
- Old style branched alkylbenzene sulfonic acid (ABS): poor degradation, gradually phased out in China.
