5 and 25 Kilo Bag Option for Caustic Soda Pearl

Overview: What is Caustic Soda Pearl?

An inorganic compound, Caustic Soda, is a white solid that is also commonly known as Lye in some industries. As the name suggests, it is a caustic product created from sodium cations and hydroxide anions (hence also being known as Sodium Hydroxide).

The manufacture of Caustic Soda occurs as a solution. Electrolytic processes on sodium chloride solutions create both Caustic Soda and Chlorine Gas. This reaction is then evaporated to provide Caustic Soda as its solid form. Milling and cleaning created the many different forms that are sold. These forms include flakes, prills, powders, grains and cast blocks. With these final forms, some companies convert them back into solutions of varying concentrations for a more straightforward application and use.

Another production method used historically more often occurs through treating Sodium Carbonate with Calcium Hydroxide. The process was called causticizing. This process created Sodium Hydroxide and Calcium Carbonate as a result. Following the process, you could then separate them both by creating a solution. As Calcium Carbonate is not soluble, it could be filtered out easily.

With Caustic Soda Pearl, it has one primary application: a very strong base in countless reactions throughout the personal care and industrial industries. However, it is very hazardous to handle with it being so strong of a base; contact with living tissue will cause it to digest what it touches. Chemical burns from mishandling can occur if not immediately and thoroughly washed for several minutes, resulting in issues affecting the person affected.

Caustic is most commonly found in the manufacture of soaps and detergents to create cleaning agents. In more concentrated volumes, it can be added as an active aspect in drain cleaners. Beyond these, many industrial manufacturers use Sodium Hydroxide as a component in artificial textiles, paper manufacture, purifying metals, as a degreasing agent and also in both dyes and bleaches.

Less common, but some specific food applications also use Sodium Hydroxide in both the cleaning, processing and even as a component in their manufacture. German Pretzels, Bagels and Chinese Moon Cakes both use Lye Water to contribute to their unique crusts. Additionally, olives use it to soften them for consumption, whilst many fruits and vegetables use it for peeling and washing. The concentrations in these are significantly different in comparison to the cosmetic and industrial applications, however.
