If you want to make luxurious hydrating homemade soap you have to Superfat your recipe and this is achieved by creating a lye discount in your recipe. Whilst this may seem confusing at first there is an easy chart with which you can work so you know in the first instance how much Lye it takes to turn 1oz of oils and fats into the soap in the saponification process.<\/p>\n\n\n\n
This chart provides a list of fats and oils commonly used in soap making at 1oz values.<\/p>\n\n\n\n
That is in the value in the lye column is how much lye is required to turn 1oz of oil into soap. You will need to calculate this value based on the amount of fat or fats used.<\/p>\n\n\n\n
This chart must be used as a guide only and the specific and Current Saponification value [See below] gained from the specific oil that will be used<\/p>\n\n\n\n Whilst the chart above has some definite figures for the saponification formula, they are based on only a single source or average of the value across a range of saponification values for each oil.<\/p>\n\n\n\n In this I mean that two different batches of oil may have come from different crops and therefore will differ slightly in their make, slightly adjusting the exact saponification value of one batch against another, even from the same manufacturer.<\/p>\n\n\n\n You can find the SAP value of your desired oil as it should be on the packaging of the product you are buying. if it is not present then choose an alternative brand or product so you know the exact value.<\/p>\n\n\n\n How to use the SAP chart for Superfatting<\/p>\n\n\n\n I have a complete article on the full process for superfatting your homemade soap and the steps and calculations to carry out<\/p>\n\n\n\nOil or Fat<\/th> Lye <\/th><\/tr><\/thead> Almond Oil<\/td> 0.1367<\/td><\/tr> Aloe Vera Butter<\/td> 0.1788<\/td><\/tr> Aloe Vera Oil<\/td> 0.1421<\/td><\/tr> Avacado Butter<\/td> 0.1339<\/td><\/tr> Avacado Oil<\/td> 0.1337<\/td><\/tr> Babassu Nut Oil<\/td> 0.1749<\/td><\/tr> Beeswax<\/td> 0.0689<\/td><\/tr> Canola Oil<\/td> 0.1328<\/td><\/tr> Castor Bean Oil<\/td> 0.1286<\/td><\/tr> Cocoa Butter<\/td> 0.1378<\/td><\/tr> Coconut Oil [Refined]<\/td> 0.1910<\/td><\/tr> Coconut Oil [Hydrogenated]<\/td> 0.1910<\/td><\/tr> Coconut Oil [Fractionated]<\/td> 0.2321<\/td><\/tr> Corn Oil<\/td> 0.1368<\/td><\/tr> Evening Primrose Oil<\/td> 0.1362<\/td><\/tr> Flaxseed Oil<\/td> 0.1358<\/td><\/tr> Goose Fat<\/td> 0.1349<\/td><\/tr> Grapeseed Oil<\/td> 0.1321<\/td><\/tr> Hazelnut Oil<\/td> 0.1369<\/td><\/tr> Hempseed Oil<\/td> 0.1359<\/td><\/tr> Lanolin<\/td> 0.0748<\/td><\/tr> Lard<\/td> 0.1399<\/td><\/tr> Linseed Oil<\/td> 0.1358<\/td><\/tr> Olive Oil<\/td> 0.1353<\/td><\/tr> Palm Oil<\/td> 0.1420<\/td><\/tr> Peanut Oil<\/td> 0.1367<\/td><\/tr> Pumpkin Seed Oil<\/td> 0.1389<\/td><\/tr> Rapeseed Oil<\/td> 0.1328<\/td><\/tr> Sesame Seed Oil<\/td> 0.1336<\/td><\/tr> Shea Butter<\/td> 0.1296<\/td><\/tr> Sunflower Seed Oil<\/td> 0.1358<\/td><\/tr> Beef Tallow<\/td> 0.1419<\/td><\/tr> Sheep Tallow<\/td> 0.1384<\/td><\/tr> Walnut Oil<\/td> 0.1349<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n How to find the Current Saponification Value<\/h2>\n\n\n\n
