Saccharin Sodium (CAS 128-44-9) is the sodium salt of saccharin with the formula C₇H₄NNaO₃S (anhydrous MW 205.17; dihydrate MW 241.20). It is a high-intensity artificial sweetener approximately 300–500 times sweeter than sucrose. Saccharin sodium is highly water-soluble and is the standard commercial form of saccharin, used in tabletop sweeteners, beverages, canned foods, and pharmaceutical taste-masking.
TCS Industries Limited, a Hong Kong-based trading and sourcing company, supplies Saccharin Sodium in food (FCC) and pharmaceutical (USP-NF) grades for global procurement programs.
> Applications
Sugar-free food and beverage sweetener
Saccharin sodium is used in diet beverages, tabletop sweeteners, canned fruits, salad dressings, and sugar-free confectionery. It is heat-stable (suitable for cooking and baking) and acid-stable (suitable for carbonated beverages). A metallic or bitter aftertaste can occur at high concentrations; blending with other sweeteners (cyclamate, aspartame, acesulfame K) mitigates this. Weihrauch et al. (Ann Oncol, 2004, 15:1460–1465) reviewed the epidemiological evidence on saccharin safety, confirming no association with cancer in humans.
Pharmaceutical and oral care applications
Saccharin sodium (USP-NF) is used as a sweetening agent in oral liquids, chewable tablets, toothpaste, and mouthwash formulations. It is non-cariogenic and provides intense sweetness at very low concentrations (0.02–0.05% in oral care products). Listed in the FDA IID for multiple dosage forms.
> Sourcing & Supply
TCS Industries Limited supports development, qualification and commercial purchasing discussions for Saccharin Sodium with buyers in Germany, France, Italy, Spain, the United Kingdom, the United States, Canada and Australia.
- Evaluation and commercial quantities: 5 kg samples for formulation trials; 25 kg drums for production. Anhydrous and dihydrate forms, food (FCC) and pharmaceutical (USP-NF) grades available.
- Pallet quantities and production campaigns: repeat supply is coordinated against packaging, lead time, annual demand and destination-market import requirements.
> Quality & Documentation
Key specification parameters include assay (≥99.0% on dried basis for USP-NF), water content (dihydrate: 12.0–15.0%), o-toluenesulfonamide (≤25 ppm per EU specification), benzoic acid and p-toluenesulfonamide (related impurities), heavy metals (Pb ≤1 ppm), arsenic, pH, and clarity of solution. White crystalline powder. COA and MSDS are standard.
> Packaging
Saccharin Sodium dihydrate may effloresce in dry conditions. Standard packaging includes 25 kg fibre drums with PE liner. Store at controlled room temperature (15–25 °C). Shelf life is typically 36 months. Labels and documents are checked before dispatch.
> Pricing & MOQ
Pricing is quoted by specification, packaging and destination. Common commercial discussions use 25 kg bag/drum formats, pallet quantities and production-campaign planning; smaller samples may be reviewed for qualified formulation teams.
> Regulatory & Compounding Context
Saccharin is approved as a food additive in the EU (E954, max use levels per food category), US (FDA-approved, removed from carcinogen list in 2000), and globally. ADI: 5 mg/kg bw/day (JECFA). Monographed in USP-NF, FCC, and Ph.Eur. (Saccharinum natricum). The EU specifies maximum levels in food categories (Regulation 1333/2008). No special import permits required.

> FAQ
Is Saccharin safe for consumption?
Yes. Saccharin was removed from the US NTP carcinogen list in 2000 after extensive human epidemiological data showed no cancer association. JECFA, EFSA, and FDA consider saccharin safe at established ADI (5 mg/kg bw/day). The earlier rat bladder cancer finding was species-specific and not relevant to humans.
What documents are available for Saccharin Sodium orders?
COA and MSDS are standard for commercial discussions. COO, packing list, invoice and other import-support documents can be arranged according to order scope.
Do you supply Saccharin Sodium to Germany, France and Spain?
Yes. We support B2B buyers in Germany, France, Italy, Spain, the United Kingdom, the Netherlands, Poland and Switzerland, subject to route and document review.
Do you supply the United States, Canada and Australia?
Yes. We review the United States, Canada, Australia and New Zealand for project supply, import documents, packaging and logistics planning before quotation.
What is the difference between Saccharin and Saccharin Sodium?
Saccharin (acid form, CAS 81-07-2) is poorly water-soluble. Saccharin Sodium (CAS 128-44-9) is the highly water-soluble sodium salt. Saccharin Calcium (CAS 6381-91-5) is used where sodium restriction is needed. All provide the same sweetening intensity. Specify the salt form required.
Is Saccharin heat-stable?
Yes. Saccharin sodium is stable at cooking, baking, and pasteurization temperatures. It does not decompose under normal food processing conditions. This is a key advantage over aspartame (which is not heat-stable). It is also stable across pH 2–10.
Can you arrange samples before commercial purchasing?
Samples or evaluation quantities may be reviewed for qualified buyers after target specification, application and destination-market requirements are clarified.
How is Saccharin Sodium packaged for export?
Packaging is confirmed by quantity and material properties. Typical options include foil bags, HDPE containers, fibre drums, 25 kg bags or palletized export packaging.
Can buyer-defined specifications be reviewed?
Yes. Send the specification, methods, impurity limits and required documents. TCS can review feasibility before confirming quotation and lead time.
What payment terms are normally used?
Standard payment is 100% T/T before dispatch unless a different arrangement has been approved for an established commercial account.
What lead time should buyers expect?
Lead time depends on stock, batch size, document scope and destination. Available stock can move faster; made-to-order or pallet programs require longer planning.
Why is Saccharin often blended with other sweeteners?
Saccharin has a metallic or bitter aftertaste at higher concentrations. Blending with cyclamate (10:1 cyclamate:saccharin), aspartame, acesulfame K, or sucralose masks the aftertaste and provides a more sucrose-like taste profile. Most commercial saccharin products use blended sweetener systems.
