Sodium bicarbonate, CAS 144-55-8 (NaHCO3), is a white, mildly alkaline crystalline powder used as a food-grade leavening agent and acidity regulator (E500), a rumen buffer in animal feed, a dry sorbent for flue-gas acid removal, and a pH/alkalinity adjuster in water treatment and cleaning. PolyBlueChem supplies food-grade sodium bicarbonate to the specification below, with per-batch COA and SDS and competitive pricing on bulk volumes.
Specifications (Food Grade)
| Parameter | Specification |
|---|---|
| Content (as NaHCO3) | 99% min |
| Chloride (Cl) | 0.4% max |
| Arsenic | 0.0001% max |
| Heavy metals (as Pb) | 0.0005% max |
| Loss on drying | 0.20% max |
| pH value | 8.5 max |
| Ammonium salt (NH4) | Pass |
| Clarity | Pass |
| Whiteness | 85 min |
The tight arsenic and heavy-metal limits (0.0001% and 0.0005% max) are what make this a food-grade material; the whiteness and clarity tests cover the appearance expected in food and feed use. A full specification sheet and a certificate of analysis (COA) for each batch are available on request.

Applications
- Food and beverage – leavening agent in baking (releases CO2 on heating or with acid); acidity regulator and leavening base (E500); effervescent and beverage applications.
- Animal feed – rumen buffer in dairy and beef cattle feed to help stabilise rumen pH.
- Flue-gas treatment – dry sorbent injection to neutralise acid gases (SO2, HCl, HF) in flue-gas cleaning.
- Water treatment – pH and alkalinity adjustment, and as a mild alkaline source in process water.
- Chemical and pharmaceutical – mild base and buffering agent; effervescent and tablet formulations.
- Cleaning and personal care – mild abrasive and deodoriser in cleaning products; bath and effervescent personal-care products.
Packaging and documentation
- 25 kg PP/PE bags and 1000 kg jumbo bags; palletised for container shipment.
- Per-batch certificate of analysis (COA) and safety data sheet (SDS).
- Store sealed and dry. Sodium bicarbonate decomposes slowly on heating (above about 50 °C) and releases CO2; keep away from acids (acid contact releases CO2 rapidly).
