International Numbering System (INS) for Food Additives: 202
Food additives Europe numbers: E202

Potassium sorbate is a substance with a wide range of applications, but in medicine, it primarily functions as a preservative. Here's a breakdown of its key uses:

Main Function: Antimicrobial Preservative

• Prevents Spoilage: Potassium sorbate is most commonly used as a preservative in various medications, foods, and cosmetics. It helps prevent the growth of microorganisms like bacteria, yeasts, and molds that can cause spoilage and contamination.
• Extends Shelf Life: By inhibiting microbial growth, potassium sorbate helps extend the shelf life of products, ensuring their safety and quality for a longer period.

Applications in Medicine:

• Preservative in Medications: Potassium sorbate can be found in some syrups, injections, and other liquid medications to prevent microbial growth and maintain sterility.
• Topical Creams (Limited): In some cases, it might be used as a preservative in topical creams or ointments to prevent contamination during storage and use. However, this use is less common.

Safety Considerations:

• Generally Safe: Potassium sorbate is generally considered safe for most people when used in the approved amounts as a preservative.
• Potential for Skin Irritation: In rare cases, topical application of potassium sorbate might cause mild skin irritation in some individuals.

Important Notes:

• Not a Direct Medication: Potassium sorbate itself is not a medication that treats any medical conditions. It acts as a preservative to maintain the safety and quality of other products.
• Regulation: The use of potassium sorbate as a food additive is strictly regulated by safety authorities like the FDA (Food and Drug Administration) in the US.
