There has been some research showing that in some rare cases when used in cosmetics or skincare products, potassium sorbate may cause skin allergies for some people. However, Potassium Sorbate is safe for everyday use in small amounts and is safe to eat according to the FDA. For topical application, a concentration of no more than 0.2% is unlikely to constitute a safety hazard.

High consumption of phosphates, including SAPP, may contribute to excessive phosphate levels in the body, which has been associated with various health issues such as cardiovascular disease, kidney problems, and bone density loss. However, these concerns are typically relevant only in the context of consuming large quantities of phosphate additives over an extended period. For most consumers, moderate consumption of food products containing sodium acid pyrophosphate is not considered harmful.

The industrial applications of phosphoric acid are equally vast. It is a critical component in the production of phosphate esters used in detergents and surfactants. In the metal industry, phosphoric acid is utilized in the process of metal treatment and rust removal, often referred to as passivation. This process not only cleans metals but also provides a protective layer that prevents corrosion, thereby prolonging the lifespan of metal products. Additionally, phosphoric acid is integral to the manufacturing of phosphoric acid esters, which are used as plasticizers and flame retardants in various materials.

One of the most common applications of sodium metabisulfite is as a food preservative. It is widely used in the food and beverage industry to prevent spoilage and oxidation, particularly in dried fruits, wines, and certain types of juices. By inhibiting the growth of bacteria, yeast, and molds, sodium metabisulfite helps extend the shelf life of these products. Moreover, it prevents browning reactions in fruits and vegetables, maintaining their appealing appearance. The FDA has recognized sodium metabisulfite as safe for use in limited quantities, although it can cause allergic reactions in some individuals, particularly those with asthma.
