LUBON INDUSTRY Co., LTD are specialize in producing Potassium sorbate. Used very broad.
Potassium sorbate is a white to pale yellow crystalline flake, crystalline granule or crystalline powder, odorless or slight odor, hygroscopic long-term exposure to air, oxidation and decomposition and discoloration. Water-soluble potassium sorbate
Has a strong inhibitory effect of spoilage bacteria and fungi, and because of the low toxicity than other preservatives, it has become the world’s leading preservatives. Under acidic conditions, corrosion can give full play the role of a neutral role when low.
Also can be used in Cosmetic preservatives . An organic acid preservatives . Average amount of 0.5% . May be mixed with sorbic acid . Although potassium sorbate soluble in water, easy to use, but its pH 1% solution is 7-8, so there is a tendency to increase the pH of cosmetics, should be taken when using.
Sorbic acid (potassium) in a sealed condition stable, exposed and easy to absorb water, moist air oxidation and discoloration . Potassium sorbate better thermal stability , decomposition temperatures up to 270.
When you use can be added directly, spraying, dipping, powder spray on the packaging material handling and other means.
Potassium sorbate and bases, oxidizing and reducing agents are incompatible. When faced with non-ionic surfactants and plastic sorbic acid antimicrobial activity will be reduced. Heavy metal salt capable of catalyzing the oxidation reaction . Sorbic acid can react with the sulfur-containing amino acids, this reaction may be added Vitamin C, propyl gallate or butyl hydroxy toluene suppressed.
When the solution is kept in a glass container on the pH is very sensitive. Therefore, the use of potassium sorbate as a preservative in the formulation to be stored for a long amount of time after the detection of microorganisms .
If sorbic acid solution stored in polypropylene, polyvinyl chloride or polyethylene containers without added antioxidants, sorbic acid will quickly degrade.
