Properties and Applications: Slightly soluble in water. Soluble in fat and glycerin. An unsaturated fatty acid. Naturally found in many plants. Sorbic acid and its salts are used as preservatives for a wide range of food products and their packaging materials, just like in food products. Because they have broad effectiveness in preventing most molds, yeasts, and bacteria. Also used as fungistatic agents in foods. Especially used as a mold preventive in products such as cheese, syrup, jelly, cake, wine and fruit. Low pH values require low amounts of sorbic acid. Also used in cosmetics, pharmaceuticals, tobacco and sweetening products. Used to prevent secondary fermentation of increased sugar in wine. Used to improve brightness in coating and as an intermediate in the production of plasticizers and lubricants. Also used in rubber industry to improve grinding characteristics.
Typical usage concentrations are between 0.2-0.5%. Advantages: mostly effective against fungi and low toxicity. Disadvantages: moderate activity against bacteria, low water solubility, most effective at pH 2-5, incompatible with cationics and some nonionics.
