It is also a common ingredient in toothpaste, acting as a gentle abrasive to help remove plaque and surface stains. This process, known as freezing point depression, prevents ice from forming or helps melt existing ice and snow, reducing the risk of accidents.
These products are the building blocks for countless other chemicals. Chlorine is used to produce PVC plastics, disinfectants, and solvents, while sodium hydroxide is essential in the production of paper, soap, and textiles.
