High Quality Potassium Sorbate with CAS number 24634 - 61 - 5 is a potassium salt of sorbic acid. It is a white to off - white crystalline powder or granular substance with a slight characteristic odor.
Chemical formula: C₆H₇KO₂. Molecular weight: 150.21 g/mol. It is soluble in water, and the solubility at 20°C is about 58.2 g/100 ml. It is also soluble in ethanol and propylene glycol to some extent. The pH value of a 1% aqueous solution is approximately 7 - 9. The product is known for its high purity and low price, which makes it a cost - effective choice for various industries.
Potassium sorbate is widely used as a preservative in the food industry. It inhibits the growth of mold, yeast, and certain bacteria, thereby extending the shelf - life of food products. It can be found in a variety of food items such as cheese, yogurt, bakery products, and beverages.
In the cosmetic industry, it serves as a preservative to prevent the growth of microorganisms in creams, lotions, and other personal care products. This helps maintain the quality and safety of these products during their shelf - life.
It is also used in the pharmaceutical industry to preserve liquid medications, preventing spoilage and ensuring the stability of the active ingredients.
When using potassium sorbate in the food industry, it is usually added during the processing stage. The dosage depends on the type of food and the regulatory requirements. For example, in most cases, the maximum allowable level in food is regulated by national and international food safety standards. It can be dissolved in water first and then added to the food mixture to ensure uniform distribution.
In cosmetics, it can be added to the water phase of the formulation. The recommended concentration range is typically between 0.1% - 0.5%, but this can vary depending on the specific product and its intended use.
In pharmaceuticals, it is added to liquid formulations at an appropriate concentration to meet the stability and safety requirements of the medication.
Case 1: A bakery company was facing issues with mold growth in its bread products, which led to a high rate of product returns. After adding potassium sorbate to the bread dough at a concentration of 0.1%, the shelf - life of the bread increased from 3 days to 7 days. This significantly reduced product waste and improved customer satisfaction.
Case 2: A cosmetic manufacturer was struggling to keep its moisturizing lotion free from microbial contamination. By incorporating 0.2% potassium sorbate into the formulation, the lotion remained stable and free from visible signs of spoilage for over 12 months under normal storage conditions.
Case 3: A pharmaceutical company producing an oral liquid medication had problems with the degradation of the active ingredients due to microbial growth. After adding an appropriate amount of potassium sorbate as a preservative, the stability of the medication was improved, and its shelf - life was extended from 6 months to 18 months.
