Sodium hydroxide, white crystalline, is also known in other terms such as Lye, caustic soda, white caustic, lye soda, and sodium hydrate. The chemical formula is NaOH, and it is known to be corrosive as well as soluble in water, alcohol, and glycerin.
Chemicals can sound foreign to you but can be found in household products such as oven cleaners and drain cleaners. The thing about cleaners that contain the substance is that they tend to turn fats into soap, making them efficient in removing clogs from pipes which are usually a mixture of fats and grease.
Its value does not end on these household product. It is valuable in many other ways the same as its role in the paper industry where it used to break lignin on wood. Lignin brings together cellulose fibers in wood, and the removal is responsible for having the released cellulose fiber formed into paper. So now you can imagine how important this substance is in the paper industry.
In addition to being a contributor to paper production, this substance is also valuable for the food industry. It plays an important role in processing of chocolate and cocoa, caramel coloring production, peelers of fruits and vegetables, and poultry water.
