Here are two products that are made using sodium hydroxide (NaOH), also known as lye or caustic soda:

1. Soap: Sodium hydroxide is a key ingredient in the saponification process, which is the chemical reaction that turns fats and oils into soap.

2. Paper: Sodium hydroxide is used in the pulping process, which separates the fibers from wood to create paper. It helps to dissolve lignin, a substance that binds the fibers together.

Sodium hydroxide is a versatile chemical with numerous applications in various industries.
