Uses and properties
Sorbic acid, or 2,4-hexadienoic acid, is a white crystalline powder or granule form. It is a natural organic compound used mainly as a food preservative. Sorbic acid and its mineral salts, such as potassium sorbate, are antimicrobial agents characterised by their broad effectiveness to inhibit moulds, yeast, and many bacteria. As a preservative, it is added to foods, pharmaceuticals, personal care products, cosmetics and other industrial products to reduce spoilage that air, fungi, bacteria, or yeast can cause.
Sorbic acid/potassium sorbate has been included in the European Biocides Scheme (Biocidal Products Directive 98/8/EC). Since May 2000, the marketing and use of biocides is regulated in the European Union by the aforementioned directive. To continue the marketing and use of an active substance in a certain product type in the European Union, the substance must be included in the positive list (Annex I) for that use area.
The members of SARG have submitted a full dossier on sorbic acid (CAS Nr 110-44-1; EC 203-768-7) and its salt potassium sorbate (CAS Nr 24634-61-5; EC 246-376-1) as active substances in the framework of the Biocidal Products Directive.
