The main difference between liquid soap and bar soap is the lye. Bar soap uses Sodium Hydroxide and liquid soap uses Potassium Hydroxide. Otherwise, the warming-blending-sitting process is identical to bar soap. But after the night of rest in the “mould,” instead of cutting the bars, we add water and stir.

Liquid Soap

3.375 oz Potassium Hydroxide (KOH)
8 oz water
5 oz coconut oil
1 oz castor oil
11 oz vegetable shortening

1. Warm your oils until liquefied and sprinkle the lye into your water.

2. When they’re cool enough to touch, slowly pour lye water into fats.

3. Blend.
