Soda Ash 99.4% (Sodium Carbonate)
Formula:
Na2CO3
GOST/CAS:
ГОСТ 5100-85 / CAS 497-19-8
Soda Ash 99.4% (anhydrous sodium carbonate) is a highly purified inorganic compound that appears as an odorless, white crystalline powder with excellent water solubility. Due to its alkaline properties, high purity, and superior pH-regulating capacity, this product serves as an indispensable component in the food industry (registered as food additive E500i) as well as in detergent manufacturing, water treatment, and various branches of light and heavy industries.
Applications
Food Industry (E500i): Acts as an acidity regulator, raising agent (leavening agent), and anti-caking agent. It is widely used in baking, confectionery, processed cheese production, milk powder processing, as well as in brewing and cocoa bean processing.
Household & Industrial Detergents: Functions as a core ingredient in formulations for laundry powders, cleaning pastes, and dishwashing detergents. It effectively softens water, saponifies fats, and boosts the performance of surfactants.
Water Treatment & Effluent Neutralization: Utilized to neutralize acidity in industrial wastewater, reduce water hardness (by precipitating calcium and magnesium ions), and balance pH levels at water purification plants.
Glass & Chemical Manufacturing: Used as a flux in glass melting (for optical glass, medical glassware, and crystal) and serves as a primary raw material for synthesizing other sodium compounds (such as monosodium glutamate, sodium phosphates, etc.).
Key Advantages
High Purity (99.4%): Minimal trace impurities and heavy metal content guarantee the stability of technological processes and full compliance with strict food safety standards.
Effective pH Regulation: Rapidly and reliably neutralizes excess acidity, creating an optimal alkaline or neutral environment in solutions and finished products.
Universal Water Softening: Binds hardness salts to prevent scale buildup on equipment, significantly enhancing the washing and cleaning efficiency of detergent systems.
Eco-Friendly & Safe: The product is fully biodegradable, non-toxic at working concentrations, free of volatile organic compounds (VOCs), and completely safe for the environment when standard disposal guidelines are followed.
Storage & Transportation
- Store in dry, cool, and well-ventilated warehouses in tightly sealed original packaging, away from moisture and heat sources.
- Recommended temperature range: No strict limits; however, the product is highly hygroscopic, making strict humidity control essential.
- Avoid direct sunlight and moisture exposure, as the powder is prone to caking and losing its free-flowing properties when in contact with water or steam.
- Transportable by all types of covered vehicles provided weather protection is ensured. The material is classified as non-hazardous for transport. Shelf life is 1 year from the manufacturing date (in airtight packaging).
