SAP values for common oils and fats

The following chart will give you the saponification values for the most common oils, fats and butters used in soap making, as well as some important properties of the oils to help you create your own soap recipe.

A typical soap recipe will have a selection of hard and soft oils, a 5-8% superfat ratio (the percentage of oils that do not saponify), and around 1/3 water content (roughly 350 ml of water per 1000 g of oils). This will ensure a solid, long lasting bar of soap with a good lather and isn’t too drying on the skin.

To find out more about making your own recipes, you can visit one of my workshops or follow my blog for soap making tips and tricks.
