In cold process soap making, some soapers prefer using pomace oil instead of Grade A olive oil . Pomace oil is solvent extracted from previous pressings of olives using the skins and pits (pomace). Pomace oil has a high percentage of unsaponifiables, and it tends to draw the oils into a quick saponification. Use caution when using pomace oil with fragrance oils or GSE as both speed up the saponification process.
