I'm not sure if you want the raw material is which NaOH is USED or in which NaOH is made. NaCl is something used to make NaOH. That may sound weird but look up the electrolysis of brine. It makes H2, Cl2, and NaOH. Made by PPG in plants around the U.S. One such plant is in Lake Charles, LA.
One raw material from which sodium hydroxide is manufactured is sodium chloride, also known as common table salt.
