Potassium sorbate, food-grade preservative, prevents mold, yeast, and microbes.
Benzoic Acid, USP, FCC, Kosher, ACS Reagent, >99.5%
Benzoic Acid (C₆H₅COOH) is a high-purity compound (>99.5%) widely used as an antimicrobial preservative in the food and beverage industry. Its potent antibacterial and antifungal properties, particularly effective at pH levels between 2.5 and 4.0, make it ideal for preventing spoilage in carbonated beverages and other acidic foods. Benzoic Acid is USP, FCC, Kosher, and ACS Reagent grade, ensuring its suitability for food-grade, industrial, and laboratory applications. With a molar mass of 122.12 and a melting point of 122.13°C, it is a reliable chemical for both practical and analytical uses. A Certificate of Analysis (COA) can be ordered for detailed specifications.

Potassium Sorbate, FCC, Kosher, Food Grade Preservative
Potassium sorbate (K-sorbate) is a commonly used preservative in foods, wines, the baking industry, and personal care products to prevent mold, yeast, and microbial growth. Typical applications include cakes, icings, beverage syrups, cheese, dried fruits, margarine, pie fillings, and wine. Usage concentrations vary depending on the specific application. Potassium sorbate is water-soluble, with the molecular formula C6H7KO2, and comes in noodle-shaped granules. It is effective at pH levels up to 6 but loses effectiveness rapidly at higher pH levels.
Product Specifications
| Chemical Formula | C6H7KO2 |
| Grade | FCC, Kosher |
| Physical Form | Noodle-shaped granules |
| Effective pH Range | Up to 6 |
| Applications | Foods, wines, baking, personal care products |
Applications and Benefits:
- Preserves food by preventing mold, yeast, and microbial growth
- Widely used in cakes, icings, and syrups
- Ideal for cheese, dried fruits, and margarine
- Used in personal care products to inhibit microbial activity
Caution:
Use concentrations as per specific application requirements. Not effective at pH levels above 6.
Sodium Metabisulfite, 98%
Sodium metabisulfite (SMBS) is commonly used for removal of free chlorine and as a biostatic. Other chemical reducing agents exist (e.g., sulfur dioxide), but they are not as cost-effective as SMBS. When dissolved in water, sodium bisulfite (SBS) is formed from SMBS: Na2S2O5 + H2O → 2 NaHSO3, then reduces hypochlorous acid according to: 2NaHSO3 + 2HOCl → H2SO4 + 2HCl + Na2SO4. In theory, 1.34 mg of sodium metabisulfite will remove 1.0 mg of free chlorine. In practice, however, 3.0 mg of sodium metabisulfite is normally used to remove 1.0 mg of chlorine.
