Factors affecting the shelf life of PFS

Shelf life refers to the better service life of the product. The products within the shelf life show that the quality of the products meets the relevant standards and can be used safely. The shelf life is determined by the producer according to the stability of product quality. In addition to the shelf life, there is also the production date. Shelf life is not only defined in food, but also for industrial products, daily necessities and chemical products. The shelf life of PFS can be divided into solid product shelf life and liquid product shelf life.

For the common polyferric sulfate in the market, the shelf life of solid polyferric sulfate is one year, while the shelf life of liquid product is relatively short, generally six months.

Factors affecting the shelf life of PFS

1. Product quality factors. The stability of liquid PFS is mainly affected by the basicity. The lower the basicity, the better the stability. When other conditions are the same, the higher the content of the product, the higher the basicity; however, the content is not the only factor affecting the basicity.

2. Storage environment. The shelf life marked on the product mostly refers to the shelf life in a certain environment. This product should be stored in a dry, cool and ventilated place. Therefore, the changes of storage factors such as sunlight and rain are the major factors affecting the stability of PFS.

In addition, the packaging of the product and the influence of other drugs around may shorten its storage life. For solid products, it is recommended that they be prepared and used now, but not dissolved in water for a long time.
