Saccharin Sodium CAS 128-44-9 is the water-soluble sodium salt of o-benzosulfimide , chemically defined as 1,2-benzisothiazol-3(2H)-one 1,1-dioxide sodium salt, functioning primarily as a high-intensity non-nutritive sweetener in feed additives and as a primary brightener in industrial nickel electroplating baths. Also known as Soluble Saccharin or Sodium o-benzosulfimide, this crystalline powder is utilized to mask unpleasant tastes in pharmaceutical or animal feed formulations and serves as a stress-reducing agent in metal finishing to improve the ductility and brightness of nickel deposits. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.

2. Multi-Sector Applications
- Food & Beverage: The go-to sweetener for sugar-free sodas, pickles, and confectionery. Its heat stability makes it superior to aspartame for baked goods.
- Electroplating (Industrial Grade): Acts as a primary brightener in nickel plating baths, improving the ductility and luster of the metal finish.
- Oral Care: Essential in toothpaste and mouthwash to mask bitter ingredients without promoting tooth decay.
- Pharmaceuticals: Used as a masking agent in syrups and chewable tablets.
- Animal Feed: Used to increase feed intake in livestock by improving palatability.
3. Storage and Shelf Life
To maintain the integrity of the crystal structure and the purity of the product, proper storage is critical:
- Environmental Control: Store in a cool, dry, and well-ventilated area. Saccharin Sodium is slightly hygroscopic (absorbs moisture), so high humidity can lead to clumping.
- Container Integrity: Keep containers tightly closed when not in use. Original Kraft paper bags with PE liners or plastic drums are recommended.
- Incompatibility: Keep away from strong oxidizing agents and strong acids to prevent chemical degradation.
- Shelf Life: When stored under optimal conditions, the product typically maintains a shelf life of 3 to 5 years.
4. Safety Precautions & Handling
While Saccharin Sodium is non-toxic and GRAS (Generally Recognized As Safe) for consumption, industrial handling requires standard safety protocols:
- Personal Protective Equipment (PPE):
- Respiratory: Use a dust mask (N95 or equivalent) if handling bulk powder to avoid inhalation.
- Eyes: Wear safety goggles to prevent irritation from dust particles.
- Skin: Wear standard industrial gloves and protective clothing to minimize prolonged skin contact.
- First Aid:
- Inhalation: Move to fresh air.
- Skin/Eye Contact: Flush with plenty of water.
- Hygiene: Do not eat, drink, or smoke in the handling area. Wash hands thoroughly after use.
- SDS Availability: We provide a full Safety Data Sheet (SDS) with every shipment to ensure your facility remains compliant with local safety regulations.
5. Quality Control: The “China-Direct” Advantage
Sourcing from China doesn’t mean compromising on quality. We ensure:
- Strict Batch Testing: Every shipment is verified by HPLC for purity and checked for heavy metals (Lead, Arsenic) to ensure they meet BP 2024 / USP 43 standards.
- Traceability: Every bag comes with a batch number that links directly back to the production date and raw material analysis.
6. Customization & Service
Mesh Size Customization: From large “diamond” crystals (4-6 mesh) for visual appeal to ultra-fine powder (100 mesh) for rapid dissolution.
Packaging Solutions: 25kg standard bags, 1kg retail-ready packs, or 1000kg jumbo bags for industrial-scale operations.
Regulatory Documentation: We provide all necessary paperwork for international trade, including REACH, Halal, Kosher, ISO, and Health Certificates.
FAQ - Technical & Supply Chain
-
Q:
How is Saccharin Sodium (CAS 128-44-9) chemically distinguished from acid Saccharin?
A: Saccharin Sodium (CAS 128-44-9) is the sodium salt form, which exhibits high water solubility compared to the insoluble acid form (Saccharin). In industrial verification, it is identified by its sodium content and immediate dissolution in aqueous systems, making it suitable for liquid formulations where the acid form would precipitate. -
Q:
What is the function of Saccharin Sodium in industrial electroplating applications?
A: In the electroplating industry, specifically for nickel plating, this material is intended for use as a Class I brightener. It acts as a stress reliever and grain refiner in the plating bath, allowing for the deposition of ductile, semi-bright nickel layers.
