Sodium Hydroxide: LYE - for Soap Making. Sodium Hydroxide, or Lye, is the chemical that induces saponification with fats and oils to create that magnificent thing called soap! Our lye is now in flake form! This is a huge improvement because they don't cling to you and your tools due to static electricity like the pellets do. The flakes are a little less pure (97% instead of 99%) but this small variation does not make a difference in soap recipes and saponification rates.Please be sure to educate yourself on the safety precautions and proper handling of Lye before using this ingredient. Our Lye is 32 oz. by volume and 27 oz. by weight.
