To avoid any wasted soap, make sure to keep your lye tightly sealed in a cool, dry place. We like to mark all of our bottles in the Soap Lab with the date it is opened.
How do you store caustic soda?
Caustic soda crystallizes at low temperatures. Keep storage temperatures controlled in the range 85 F to 100 F (29 C to 38 C). If the temperature drops below 65 F (16 C), the viscosity of the product increases, which may affect its performance.

- Add 2.56N Sulfuric Acid, drop by drop, mixing after each addition and counting the number of drops until the color changes from pink to colorless.
What is the difference between lye and caustic soda?
Caustic soda is sodium hydroxide which is lye – they are the exact same thing; just different names. The reason behind the different names is mainly to do with the chemical name being “sodium hydrate” and the chemical itself is “caustic or corrosive”, leading to being known as caustic soda.
Can you still buy caustic soda?
