Shortening (Vegetable Shortening)
All-vegetable shortening can substitute for palm oil, though recipes need adjustment as formulations vary by brand. Shortening creates hard bars with decent lather. Using vegetable shortening for Cold Process soap is difficult because the proportions of oils can vary which may change the SAP value. Without an accurate SAP value, creating a successful Cold Process soap recipe is difficult.
