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. For technical specs (e.g., active matter %, free acid content), specify your application!
