Product name: Potassium sorbate CBnumber: CB3294185 CAS: 590-00-1 EINECS Number: 611-771-3 Physical characteristics Colorless to white scaly crystals or crystalline powders, odorless or slightly odorous. Unstable in air. It can be colored by oxidation. Molecular weight 150.22. It is hygroscopic. Soluble in water and ethanol. Production method The neutralization method is mainly used. It is obtained by neutralizing sorbic acid with potassium carbonate or potassium hydroxide. Potassium sorbate is made of sorbate and potassium carbonate as raw materials, because the production technology is simple, only one step reaction, can complete the key process, so many small business owners, as long as a little learning, can master this technology, which is also an important reason for the increasing number of small potassium sorbate production enterprises. Due to the simple production facilities of many small enterprises, most of them have only a few houses, a reactor, a blender, several manual sealing machines and other facilities, the lack of purification devices, and manual production, so the production cost is low, but the physical and chemical quality and health quality of the products are often unstable. Scope of use At present, it has been widely used in food, beverage, pickles, tobacco, medicine, cosmetics, agricultural products, feed and other industries, from the development trend, its application scope is still expanding. Sorbate (potassium) is an acidic preservative, and it still has a good preservative effect in foods that are close to neutral (PH6.0-6.5), while the preservative effect of benzoic acid (sodium) is in PH> At 4, the effect has been significantly reduced, and there is bad taste. Cosmetic preservatives. It is an organic acid preservative. The addition amount is generally 0.5%. Can be mixed with sorbic acid. Although potassium sorbate is easily soluble in water and easy to use, the pH value of its 1% aqueous solution is 7-8, which has the tendency to increase the pH value of cosmetics, and should be paid attention to when using.
