Disclaimer: The Handcrafted Soap & Cosmetic Guild is providing this lye calculator to soapmakers free of charge. Every effort has been made to ensure that the SAP values used herein are accurate. However, even in the best case, the SAP values provided by reputable sources are only acceptable ranges for each oil. The actual SAP value being used in the calculations is the average of the highest and the lowest acceptable level for an oil and is generally considered the norm for calculating the lye necessary for soap. However, the actual SAP value of any batch of a particular oil may be somewhat higher or lower than the value used in the calculations here (even if it falls within the acceptable range).
