What is Caustic Soda?

An inorganic compound, Caustic Soda, is a compound of sodium and hydroxide. This combination also results in being known as Sodium Hydroxide. The Soap Making Industry also calls it Lye.

The manufacture of Caustic Soda occurs as a solution. Electrolytic processes on sodium chloride solutions create both Caustic Soda and Chlorine Gas. Another production method includes treating Sodium Carbonate and Calcium Hydroxide, which also supplies Calcium Carbonate.

Following the reactions, manufacturers evaporate the solution into solid forms. These forms include flakes, prills, powders, grains and even cast blocks.

There is one Primary Application of Caustic Soda: a strong base in countless reactions in the personal care and industrial industries. However, it is very hazardous to handle. When in contact with living tissue, it will digest what it touches. Accidental contact can lead to Chemical burns if not immediately and thoroughly washed for several minutes, resulting in issues affecting the person affected.

Most commonly, soap and detergent manufacturers use Caustic in their creation. In more concentrated volumes, drain cleaners use it as an active unblocker and cleaning agent. Beyond these, it can be a component in artificial textiles, paper manufacture, purifying metals, a degreasing agent, and dyes or bleaches.

Less common applications include baking. Whether German Pretzels, Bagels or Chinese Moon Cakes, they use Lye Water to contribute to their unique crusts. Beyond this, olives, fruits and vegetables use it for softening, peeling and washing their goods.
