Description

Potassium Sorbate is the potassium salt of sorbic acid, a highly effective and widely used preservative. Its primary value lies in its ability to inhibit the growth of molds, yeasts, and select bacteria, thereby extending the shelf life of a vast range of products. This makes it an essential ingredient for manufacturers in the food and beverage, personal care, and pharmaceutical industries seeking safe and reliable preservation solutions.

Application

• Food & Beverage Preservation: Extends shelf life in baked goods, dairy products (cheeses, yogurts), wines, fruit juices, dried meats, and salad dressings.
• Personal Care & Cosmetics: Prevents microbial spoilage in creams, lotions, shampoos, and other water-based formulations.
• Pharmaceuticals: Used as a preservative in certain liquid drug formulations, syrups, and topical applications.
• Animal Feed Additive: Helps preserve moisture and prevent mold growth in feed, ensuring nutritional quality and safety.
• Industrial Applications: Finds use in adhesives, latex, and other aqueous industrial products susceptible to microbial degradation.

Quality Control

Our Potassium Sorbate is produced and tested to meet stringent quality standards, including FCC (Food Chemicals Codex) and USP-NF (United States Pharmacopeia) grades where applicable. Every batch undergoes rigorous analytical testing to ensure identity, purity, and performance. A comprehensive Certificate of Analysis (COA) is available for each shipment to guarantee compliance with your 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 each use to prevent caking and maintain product integrity. Recommended storage temperature is between 15°C and 25°C.
