Lye is a crucial part of hot and cold process soap making. When combined with a fat and water, the magic of saponification occurs and soap is created. Using the correct type and amount of lye is correct.
To work out how much to use in our recipe use our free online Soap Calculator.

Sodium hydroxide or Caustic soda is used to convert fats and oils to soap. Sodium hydroxide is traditionally used to make harder soaps that dissolve less easily than those made using Potassium hydroxide. Despite both being called 'Lye' Sodium Hydroxide and Potassium Hydroxide are not interchangeable in soap recipes.

Sodium hydroxide is a highly corrosive dangerous good. This means it requires special handling by our shipper which can cause a delay in the delivery of your order.

As Sodium hydroxide is a dangerous good, it also incurs a $10.00 delivery surcharge from our shipper, this will be added to your freight bill at checkout.

Unfortunately, this charge is unavoidable by us and so will be passed on even if you spend over the freight free threshold. However, should your order total exceed $120.00, our standard courier charge of $7.95 will still be waived.
