Resources for Soapmakers

The HSMG provides various resources for soapmakers, to assist in their soapmaking endeavors. These resources are provided as a service to the industry and are available to all soapmakers, whether they are members of the HSMG or not.

Lye Calculator

The HSMG Lye Calculator is unique among the lye calculators that are available online. All lye calculators base the calculations for the amount of lye on the typical SAP (saponification) value for the oils. Since oils are defined as a range, knowing the actual SAP value being used in the calculations can help in understanding the results. The HSMG lye caluclator provides this information. (Members using the advanced lye calculator can also set the SAP value used in the calculation.)

The water necessary for a soap batch is variable, based on the formulation of oils used, the needs of the batch (i.e. will it be used for swirling, embeds, etc.) and the preferences of the soapmaker. The HSMG lye calculator gives ranges for the amount of water, based on research done by Kevin Dunn and published in his book, Scientific Soapmaking.
