Performance and Applications
- Detergent Industry: Widely used in the preparation of liquid detergents, such as shampoo, shower gel, hand wash, dish - washing liquid, bubble bath, complex soap, etc. It can also be used in washing powder and detergents for heavy - duty dirt. Replacing linear alkylbenzene sulfonic acid (LABSA) with SLES can save or reduce phosphate, and reduce the general dosage of active substances.
- Textile Industry: In textile, printing and dyeing, oil, and leather industries, it can be used as lubricant, dyeing agent, cleaner, foaming agent, and degreasing agent.
- Other Applications: Due to its good cleaning, emulsifying, wetting, thickening, and foaming properties, as well as strong hard - water resistance and high biodegradability, it can also be used in some industrial cleaning agents, such as glass cleaners, car cleaners, etc., and is often used in combination with K12, LAS - Na, 6501, etc.
Packing and Storage
- Packing: Usually packed in 110KG, 160KG, 200KG, 220KG plastic barrels, or 170KG drums. It can also be packed according to customer requirements.
- Storage: Store in a sealed container at room temperature. Keep away from strong oxidizing agents. The shelf - life is generally two years.
