What is Saccharin Sodium CAS 128-44-9?

Saccharin Sodium CAS 128-44-9 is the water-soluble sodium salt of saccharin, also known as sodium o-benzosulfimide. Its anhydrous molecular formula is C7H4NNaO3S, with molecular weight about 205.17 and EINECS 204-886-1.

How does Saccharin Sodium differ from saccharin acid and saccharin sodium dihydrate?

Saccharin acid is the less water-soluble parent sweetener, while saccharin sodium is the soluble salt form. The anhydrous salt is CAS 128-44-9; the dihydrate is CAS 6155-57-3 and contains two water molecules, so buyers should confirm whether a specification is expressed on an anhydrous or dihydrate basis.

Why is Saccharin Sodium used in nickel electroplating?

Electroplating-grade saccharin sodium acts as a Class I brightener, grain refiner, and stress reliever in nickel baths. At low use levels it improves deposit brightness, ductility, and surface smoothness without introducing calories or sweetness-related function.

Why is Saccharin Sodium suitable for sugar-free foods and baked goods?

It is about 300 to 500 times sweeter than sucrose, non-caloric, and more heat-stable than aspartame, so it can be used in sugar-free beverages, confectionery, and baked products. Its high water solubility also makes it easy to dose in liquid and solid formulations.

What roles does Saccharin Sodium play in oral care, pharmaceuticals, and animal feed?

In toothpaste and mouthwash it masks bitter or unpleasant ingredients without promoting tooth decay. Pharmaceutical syrups and chewable tablets use it as a non-caloric taste-masking agent, while feed formulations use it in controlled amounts to improve palatability and intake.

Saccharin Sodium CAS 128-44-9

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.
