Le lithopone a été découvert dans les années 1870 par DuPont. Il a été produit par la Krebs Pigments and Chemical Company, entre autres1. Il se faisait en différents grades, en fonction de la teneur en sulfure de zinc. Les qualités « bronze » et « or » contenaient 40 à 50 % de sulfure de zinc, ce qui les rendaient particulièrement couvrantes2. Bien que ce pigment ait atteint son pic de popularité autour de 1920, il s'en produisait encore annuellement plus de 220 000 tonnes en 1990. Il est principalement utilisé dans les peintures, les pâtes et les plastiques3.

  • 1. Wet Processing This method involves reacting phosphate rock with sulfuric acid to produce phosphoric acid and gypsum as a byproduct. It is the most common method for producing phosphoric acid due to its cost-effectiveness and efficiency. The resulting phosphoric acid can be used directly in fertilizers or further refined for food-grade applications.


  • Beyond nutrient retention, biochar also enhances soil structure. The porous nature of the material provides habitats for beneficial microorganisms, which play a crucial role in nutrient cycling and improving soil health. The presence of these microorganisms can lead to increased organic matter decomposition, further enriching the soil. Additionally, biochar can improve soil aeration and water infiltration, mitigating issues of compaction and improving water management—critical factors, especially in regions prone to drought.

  • Application and Challenges


  • Calcium propionate, a calcium salt of propionic acid, is a widely used food preservative recognized for its efficacy in extending the shelf life of various baked goods and other perishable items. Its chemical formula is C3H5CaO4, and it is known for its ability to inhibit mold and bacterial growth, making it an essential ingredient in the food processing industry.


  • In addition to recreational water, TCCA 90% is also instrumental in aquaculture. In fish farming operations, maintaining water hygiene is essential for the health of aquatic species. TCCA is used to control harmful pathogens that can thrive in crowded farming environments. By ensuring the water is free from harmful microorganisms, fish farmers can prevent diseases that could lead to significant economic losses.


  • In addition to its leavening properties, ammonium bicarbonate can act as a food preservative. It helps inhibit microbial growth, contributing to the safety and shelf-life of food products. This characteristic is particularly valuable in regions where refrigeration may not be readily available, allowing for longer storage of perishable foods.


  • Cancer: Low risk
  • 4. Household Cleaning Some household cleaning products incorporate TCCA for its disinfectant properties, making it useful in various applications ranging from surface disinfection to laundry sanitization.


  • Health and Safety Implications


  • The mechanism by which E212 functions involves the release of benzoic acid when it is in an acidic environment. The benzoic acid then enters the microbial cells, disrupting their internal processes, ultimately inhibiting their growth and proliferation. This property makes E212 an invaluable tool for food manufacturers to ensure product quality and safety.


  • - Fuel It is often used in portable stoves and as a fuel additive for enhancing the combustion efficiency of certain products.
  • In the pharmaceutical industry, sodium metabisulfite is utilized as an antioxidant. It helps preserve the stability of certain medications by preventing oxidative degradation. Additionally, it is used in the formulation of injectable drugs as a stabilizer, ensuring that the active ingredients remain effective over their shelf life. Its antimicrobial properties also aid in inhibiting the growth of harmful bacteria in pharmaceutical formulations.
