Caustic soda 10-50%

Caustic soda 10-50% solutions (10%, 20%, 31.5%, 40%, and 50%) are diluted aqueous solutions of sodium hydroxide, commonly used in various industrial and cleaning applications. This colorless, highly alkaline solution is effective in saponification and as a pH adjuster, but requires careful handling due to its corrosive nature.

What is Caustic Soda?

Caustic Soda, also known as Sodium Hydroxide or NaOH, is a strong alkaline compound. When dissolved in water, it becomes a clear, odourless liquid. It’s used for pH control, cleaning, and chemical reactions in a wide range of industries.

Other names:

  • Sodium Hydroxide

  • NaOH

  • Lye (used in some cleaning products)

Because it’s highly alkaline, it’s useful for neutralising acids, adjusting pH, and making other chemicals.
