Potassium Sorbate is the potassium salt of sorbic acid. Its chemical formula is C₆H₇KO₂ or CH₃CH=CH–CH=CH–COOK. Potassium sorbate works by inhibiting enzymes involved in microbial metabolism, particularly in molds and yeasts. It is most effective at low pH.
Potassium Sorbate is the potassium salt of sorbic acid, with the formula C₆H₇KO₂. This USP/FCC (Food) Grade material has CAS 590-00-1, an assay of 98.0 to 101.0%, and comes as a solid. It works by inhibiting enzymes that molds and yeasts use for metabolism, and it’s most effective at low pH. It’s certified Kosher and Halal, carries a GRAS reference citation of 21CFR 182.3640, and shows a GMO Free badge. Product Manuals include the Safety Data Sheet, Technical Data Sheet, Kosher and Halal certifications, the GRAS document, a GMO Free statement, a Food Grade statement and Certificates of Analysis. Everything’s there before you order.
Most people reach for Potassium Sorbate to slow mold and yeast growth in food, beverage and formulation work, and it’s a regular in lab testing and product development too. The problem? Impurities or missing paperwork can stall a batch before it starts. That’s where we come in. Our SDS, COA and certification documents are available instantly online. You’ll know what you’re getting before it ships. Pick a size from 100g up to 25kg, set up Autoship if you reorder, or request a quote for bulk volumes. On budget, on time, every time.
