Food/Industrial Grade 99% Sodium Benzoate (E211) Preservative CAS 532-32-1 for Food, Pharmaceutical & Cosmetic

Sodium Benzoate (E number E211, CAS:532-32-1, molecular formula C₇H₅O₂Na) is produced by neutralization of benzoic acid with sodium hydroxide, followed by refining, crystallization, centrifugation and drying process. Our goods are available in two specifications: food grade and industrial grade with minimum 99.0% effective content. The product appears as white granular crystal or crystalline powder, odorless or with slight benzoic acid smell, easily soluble in water and moderately soluble in ethanol. It owns outstanding broad-spectrum antibacterial performance against yeast, mold and partial bacteria under acidic environment, being one of the most widely approved low-cost chemical preservative globally. Food-grade products go through deep purification to strictly control heavy metal, chloride and arsenic indexes in accordance with FCC, BP, USP and China GB food additive standards; industrial grade is cost-effective for daily chemical, coating and industrial anti-corrosion usage. With stable antiseptic property and excellent formula compatibility, sodium benzoate is extensively used as preservative raw material in food processing, pharmaceutical preparation, cosmetic production and multiple industrial fields.

Applications
Food Beverage Industry (Core Food Grade Application)
Approved legal food preservative applied in carbonated drinks, fruit juice, jam, candies, pickled vegetables, soy sauce and vinegar. In acidic food system, it effectively restrain mold, yeast and harmful microorganism reproduction to avoid raw material fermentation deterioration and prolong finished food shelf life under permitted legal dosage, becoming the mainstream economical antiseptic for acid food production worldwide.
Pharmaceutical Raw Material & Medicine Preparation
Used as antiseptic and bacteriostatic agent for oral syrup, external ointment, liquid medicinal preparation and traditional Chinese medicine oral liquid. It prevents microbial contamination of liquid medicines during storage, stabilizes medicinal formula system and extends medicine validity period while complying with pharmaceutical raw material inspection specifications.
Cosmetic & Personal Care Products
Important preservative additive for shampoo, body wash, facial lotion, cream and aqueous cosmetics. It inhibits miscellaneous bacteria breeding inside cosmetic formulas, effectively preventing finished products from mildew deterioration during shelf storage, matching well with most surfactant and cosmetic base raw materials without obvious adverse reaction.
Industrial Grade for Daily Chemical & Coating Field
Industrial sodium benzoate works as anti-mold agent for water-based paint, latex coating, printing paste and leather finishing liquid, inhibiting mold growth inside waterborne system to avoid product rottenness and stratification; also used as intermediate raw material for organic synthesis and tobacco anti-corrosion treatment.
Other Industrial Usage
Applied as rust inhibitor for metal cutting fluid and circulating industrial water, restraining microbial reproduction and pipeline mucilage formation in water system to reduce equipment blockage risk.

Product Advantages
