Potassium sorbate, also known as potassium 2,4-hexadienoate, is the potassium salt of sorbic acid, with the molecular formula C6H7O2K, white to light yellow scale crystals, crystal particles or crystal powder, odorless or slightly odorous, long-term exposure to air Easy to absorb moisture, be oxidized and decomposed to change color. Soluble in water, soluble in propylene glycol and ethanol. Often used as a preservative.
Potassium sorbate is mainly used as a food preservative, and is also used for cosmetic preservation and feed mildew prevention. It has a strong inhibitory effect on spoilage bacteria and mold, and is easily soluble in water and is widely used. Its antibacterial effect is stronger than its bactericidal effect. The lower the pH value, the stronger the antibacterial effect. Sorbic acid (potassium) can effectively inhibit the activity of molds, yeasts and aerobic bacteria, and can also prevent the growth and reproduction of harmful microorganisms such as Staphylococcus aureus, and Salmonella, but it is almost ineffective against beneficial microorganisms such as anaerobic spore-forming bacteria and Lactobacillus acidophilus. Its growth inhibition effect is stronger than its bactericidal effect, thus effectively extending the shelf life of food and maintaining the original flavor of food. Its preservative effect is 5-10 times that of similar products such as sodium benzoate. As a cosmetic preservative.1. Potassium sorbate is an internationally recognized low-toxic, high-efficiency acid-type preservative, with the same preservative effect as sorbic acid. For the scope of use and dosage (based on sorbic acid), refer to sorbic acid.
2. Used as a food preservative, fruit and vegetable preservation and washing cosmetics and feed preservatives, etc.
3. Cosmetic preservative. It belongs to the organic acid preservative. The addition amount is generally 0.5%. It 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 tends to increase the pH value of cosmetics, so it should be used with caution.
