Chimiquement, c'est un sel de potassium de l'acide sorbique (E200). Il est synthétisé chimiquement et on le retrouve dans de nombreux aliments tels que les yaourts aux fruits, les sauces, les boissons ou encore certains beurres allégés.

Sorbates have a long history of safe use in food, pharmaceutical and personal care applications. They are considered nature identical and are ecolabel compliant. As biocidal products, under the applicable biocidal product Regulation (EU) 528/2012 (BPR), Nutrinova® Potassium Sorbate BFX Granules and Nutrinova® Sorbic Acid BFX DF have now been made available for home care formulations by Celanese, the only western manufacturer of potassium sorbate and sorbic acid. Their efficacy at use levels of 0.1-0.4%, both bactericidal and fungicidal, is demonstrated in a range of home care detergent formulations, such as manual dishwashing liquids, fabric conditioners and all-purpose cleaners. Their viability as a possible efficacious alternative to isothiazolinones in such formulations is thus supported.
