Frequently Asked Questions

What is potassium sorbate made from?

Potassium sorbate (CAS 24634-61-5) is the potassium salt of sorbic acid, produced by neutralizing sorbic acid with potassium hydroxide. It is supplied as a free-flowing granule or powder.

What is potassium sorbate used for?

It functions as a preservative and mold and yeast inhibitor in foods, beverages, and wine, and as a preservative in personal-care formulations. In food labeling it is designated E202. It is supplied to manufacturers as granule or powder.

Is potassium sorbate water soluble?

Yes, potassium sorbate is highly water-soluble, which is why it is favored over sorbic acid in aqueous systems where the free acid has limited solubility. Refer to the technical data sheet for solubility figures relevant to your formulation.

What is the chemical formula of potassium sorbate?

The molecular formula is C6H7KO2. Full identity data, including CAS 24634-61-5 and assay, are provided on the Certificate of Analysis per lot.
