Product Introduction: Sodium bicarbonate, commonly known as baking soda, is a widely used basic inorganic chemical raw material, produced through refined soda ash carbonization process with pure and stable quality. Manufactured in strict accordance with national standards GB/T 1606-2025 for industrial grade and GB 1886.2-2015 for food grade, the product is divided into three grades: high-purity refined industrial grade, general industrial grade and food grade. It features high purity, ultra-low impurities, good fluidity, fast solubility and stable physicochemical properties. With the advantages of non-toxicity, mild weak alkalinity and environmental friendliness, it is widely applied in food processing, environmental flue gas desulfurization, industrial washing, fire extinguishing, daily chemical products, aquaculture, pharmaceutical accessories and agricultural improvement, serving as a universal core raw material for industrial production and civil use.
2. Physical and Chemical Properties
The product is white, odorless fine crystalline powder with a slightly salty taste and weak alkalinity. It remains stable in dry environments at room temperature but decomposes gradually and fails in humid air. It is highly soluble in water and dissolves rapidly to form a clear and impurity-free aqueous solution with a pH value ≤8.5 (10g/L), featuring mild alkalinity and extremely low corrosiveness. It is insoluble in organic solvents such as ethanol. The product has good thermal stability; it decomposes slowly above 50℃ and completely decomposes into sodium carbonate, water and carbon dioxide at 270℃, releasing gas uniformly with mild reaction and no violent boiling. With uniform powder texture, good fluidity and low caking tendency, it is highly compatible with automated continuous feeding production lines and adapts to various working conditions.

Custom services including powder particle size screening, personalized packaging and OEM packaging are available to meet diverse procurement and production demands.
5. Main Application Fields
Food Processing Industry: As a compliant food additive, food-grade sodium bicarbonate is mainly used as a baking leavening agent for bread, biscuits, pastries, steamed buns and other pasta products. It also serves as an acidity regulator, food cleaning agent, fruit and vegetable residue remover and feed additive, featuring safety and compatibility with various food production processes.
Environmental Desulfurization & Water Treatment Industry: Widely used for flue gas desulfurization, denitrification and waste gas purification in power plants and factories, it efficiently neutralizes acidic waste gas and reduces sulfur emissions. In industrial and domestic sewage treatment, it adjusts water pH value, neutralizes acidic water, flocculates and settles impurities, and removes heavy metals and harmful pollutants, achieving stable and standard-reaching treatment effects.
Fire Extinguishing Industry: It is the core raw material of BC dry powder fire extinguishing agents. When heated, it rapidly decomposes to release carbon dioxide and water vapor, achieving cooling and smothering fire extinguishing effects with high efficiency, no residue and no pollution, suitable for the production of civil and industrial dry powder fire extinguishers.
Daily Chemical & Washing Industry: Applied as an auxiliary material for toothpaste, facial cleanser and other cleaning products, it provides mild decontamination, whitening and cleaning effects. It can also be made into household and industrial detergents to remove oil stains, scale and peculiar smells without damaging materials.
Pharmaceutical & Beauty Industry: Medical-grade sodium bicarbonate is used as an antacid auxiliary and oral cleaning care material to relieve excessive gastric acid and oral inflammation. Its mild weak alkalinity is suitable for sensitive skin cleaning and beauty formula preparation with no irritation.
Agriculture & Aquaculture Industry: It stabilizes water pH value, purifies water body and inhibits the breeding of harmful bacteria in aquaculture. In agriculture, it acts as a soil conditioner to neutralize acidic soil, supplement trace elements, improve soil structure and promote crop growth.
Other Industrial Fields: Widely used in leather tanning, mineral flotation, ceramic processing, rubber and plastic additives, chemical synthesis, metal cleaning, dust removal and other industrial scenarios with extensive applicability.
6. Packaging, Storage & Transportation
Conventional Packaging: 25kg double-layer sealed woven bags with inner moisture-proof film, featuring moisture-proof, leak-proof and damage-proof performance to prevent caking. 1000kg bulk ton bags are available.
