Help with my Castile Soap

ShareThis

I've made many successful Castile soap recipes before without problems however, this last batch is still soft to the touch after 24-hours. Here's the recipe:

48-oz Pomace Olive Oil
24-oz Soybean OIl
5.0-oz. Coconut Fractionated OIl
25.4-oz. Filtered water
9.8-oz. Lye
1-3/4-oz fragrance

Anybody have any idea why my soap is still too soft to slice after 24-hrs.? Usually it only takes overnight, about 12-hours. Do I need to be more patient and just wait longer or have I goofed with my recipe?
