Sodium Hydroxide:
Also called lye and caustic soda, sodium hydroxide is a chemical building block and is the primary base used to make sodium salts and other bases.

Market Dynamics:
Sodium hydroxide is a co-product of chlorine gas manufacturing, with chlorine being the economic driver. The key market for chlorine is PVC/construction; when the construction market is down, chlorine (and sodium hydroxide) production is reduced. Therefore, sodium hydroxide availability is dependent upon the construction market. 

Up Stream Materials/Building Blocks:
Sodium Chloride

Chlorine Gas (co-product

Down Stream Materials Consuming Sodium Hydroxide:

​Detergents

pH regulation

Aluminium production

Oil&Gas bentonite mud systems

Oil&Gas caustic washing to remove sulfur
