Description

Potassium Sorbate is the potassium salt of sorbic acid, a highly effective and widely used preservative. It matters because it provides a safe and reliable method to inhibit the growth of molds, yeasts, and select bacteria, thereby extending the shelf life of a vast range of products. This compound is essential for manufacturers in the food and beverage, pharmaceutical, and personal care industries seeking to ensure product safety and stability. Its efficacy at a relatively neutral pH makes it a versatile choice for various formulations.

Application

• Food & Beverage Preservation: Extends shelf life in wines, cheeses, baked goods, dried meats, yogurts, soft drinks, and fruit juices.
• Pharmaceutical & Nutraceutical Products: Used as a preservative in syrups, liquid supplements, and topical formulations to prevent microbial contamination.
• Personal Care & Cosmetics: Incorporated into creams, lotions, shampoos, and other water-based products to maintain stability and safety.
• Animal Feed Additive: Helps prevent spoilage and mycotoxin formation in stored feed, supporting animal health.
• Industrial Applications: Can serve as a preservative in adhesives, latex paints, and other aqueous industrial products.

Quality Control

Our Potassium Sorbate is manufactured under strict quality management systems. It is available in grades compliant with major international standards, including Food Chemicals Codex (FCC) and Kosher certification, ensuring suitability for global food, pharmaceutical, and industrial applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) to verify purity, identity, and conformance to specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
