Potassium sorbate is synthetically produced by reacting potassium hydroxide with sorbic acid. 
It is also available naturally from some fruit berries but rarely in commercial quantity.

It is effective against yeasts and moulds but only some bacteria and works best with products that have a pH of 5.

Potassium sorbate can be used effectively with water-based products to inhibit mould.

Usually only used in products with a very high water content as in linen sprays. Cannot be used as a preservative in creams, etc. Can be used in conjunction with, but does not take the place of, a broad spectrum preservative such as Geogard 221.

Add to the water phase of formulations at a temperature below 60°C. If adding it after oil and water phases have been combined, predissolving the required potassium sorbate in a portion of the water phase will make it easier to incorporate into the formed emulsion.
