3. Key Applications

(1) Detergents & Surfactants (Primary Use, ~70% Market Share)

• Laundry Detergents: Main anionic surfactant for superior grease/oil removal.

• Dishwashing Liquids: High-foaming and degreasing agent.

• Household Cleaners: Floor/wall cleaners due to emulsifying power.

(2) Personal Care & Cosmetics

• Shampoos/Body Wash: Used as Sodium Salt (LAS) for mild foaming.

• Toothpaste: Foam booster (neutralized form).

(3) Industrial Uses

• Emulsifier: Pesticides, paints, and textile auxiliaries.

• Electroplating: Wetting agent for uniform metal coatings.

• Oilfield Chemicals: Enhanced oil recovery (EOR) by reducing crude viscosity.

(4) Other Niche Uses

• Pharmaceuticals: Intermediate for drug synthesis (high-purity grade).

• Agriculture: Adjuvant in herbicide formulations.

4. Safety & Handling

• Hazards:

  • Corrosive (causes skin/eye burns; wear PPE).

  • Environmental: Biodegradable but toxic to aquatic life at high concentrations.

• Storage: Keep in sealed HDPE containers, away from sunlight/oxidizers.

• Neutralization: Often converted to sodium salt (LAS) for safer handling.

5. Market Overview (2024)

• Top Producers:

  • China 

  • Global

    • Regulations: Complies with REACH, EPA; restricted in some eco-labels due to biodegradability concerns.

    
    

6. Why Choose DDBSA?

✅ Cost-effective vs. other surfactants (e.g., SLES).
✅ High compatibility with nonionic surfactants.
⚠️ Limitation: Requires neutralization for pH-sensitive applications.
