Description
Potassium Benzoate in its white crystal form is a compound that results from mixing potassium hydroxide with benzoic acid. As a common food preservative, it possesses a variety of traits and applications. It is particularly useful for no-wash and rinse-off goods, and it has been formulated specifically for application in the cosmetics industry. It has an extensive and well-balanced effect on the growth of fungi and bacteria, making it a desirable preservative for many different products. The Soil Association has approved this preservative system, which may be used in goods that are being certified by the Soil Association. To sum it up, Potassium Benzoate is a multipurpose preservative that has been utilized in a variety of industries with great success.
This product proves to be efficient in eliminating not only viruses but also bacteria, yeast, and mold. It is a static biological solution that possesses the necessary sterilization properties required for practical use. The contact time needed for effective microorganisms destruction in contaminated products is at least 48 hours.
When considering the usage of seriously polluted products, it is crucial to take into account the loss of active ingredients caused by their chemical reaction with microorganisms. Therefore, it is vital to ensure good production hygiene and exercise proper control over raw materials to produce finished products that are free from microbial defects.
