Other name: 2, 4-Hexadienoic acid potassium salt
Potassium sorbate - colorless to white scaly crystalls or crystal powder, odourless or a slight odor. Instability in the air. Can be oxidation coloring. The molecular weight of 150.22. Has the water absorbability. Soluble in water, ethanol.
The main use The molecular structure The molecular structure As a food preservative belongs to acidic preservative used with organic acid corrosion reaction effect increased. With potassium carbonate or potassium hydroxide and sorbic acid as raw materials was prepared. Sorbic acid (potassium) can effectively restrain the mold, yeast anaerobic-aerobic bacterial activity, so as to effectively prolong food to save time, and keep the original flavor of food.
Cosmetics preservatives. The preservative of organic acids. Adding amount is 0.5% commonly. Can be used mixed with sorbic acid. Potassium sorbate is soluble in water, easy to use, but its 1% aqueous solution ph value of 7 ~ 8, tend to make cosmetics increased ph, when use should be pay attention to.
