Potassium sorbate

Product Overview

Potassium sorbate (CAS 24634-61-5) is a globally recognized safe food preservative widely used in the food, beverage, cosmetics, pharmaceutical, and feed industries. As a white crystalline powder or crystals, potassium sorbate effectively extends product shelf life by inhibiting the growth of molds, yeasts, and aerobic bacteria.

As the potassium salt form of sorbic acid, potassium sorbate offers significantly higher water solubility (approximately 67g/100mL at 20°C), making it the preferred choice for liquid formulations. It is approved as GRAS (Generally Recognized as Safe) by major global regulatory agencies including FAO/WHO, FDA, and European EFSA, and is one of the most widely used preservatives in the food industry.

Key Applications

• Food Preservation (Largest Segment ~60%): Bakery products (bread, cakes, pastries) for mold prevention; dairy products (cheese, yogurt, cream) to extend shelf life; beverages (juices, carbonated drinks, fruit wines) to inhibit yeast fermentation; condiments (soy sauce, vinegar, salad dressings, ketchup) for preservation; meat products (sausages, ham, jerky) to suppress bacterial growth; candied fruits to prevent mold contamination
• Cosmetics & Personal Care: Shampoos, body washes, skincare products, and cosmetics preservation — mild and non-irritating, suitable for sensitive skin formulations; driven by growing consumer demand for natural and gentle preservatives
• Pharmaceutical Preparations: Oral liquids, syrups, and eye drop preservatives — low toxicity and no interaction with active pharmaceutical ingredients
• Feed Industry: Anti-mold agent for animal feed, particularly high-moisture feeds — high safety profile with no residual toxicity
• Tobacco Processing: Tobacco anti-mold treatment to extend storage life — does not alter tobacco flavor profile

Product Features

• High Safety Profile: GRAS certified with ADI of 0-25mg/kg body weight; over 10 times safer than sodium benzoate
• Broad-Spectrum Antimicrobial: Effective against molds, yeasts, and aerobic bacteria
• High Water Solubility: Potassium salt form offers significantly higher solubility than sorbic acid (67g/100mL)
