New Lye Calculator offered by the Soap Guild

The Handcrafted Soap Makers Guild now has their our own Lye Calculator!

Unlike other lye calculators on the web, the HSMG Lye Calculator allows you calculate by the total amount of oils used OR by the percentage of oils within a specified batch size. You can also calculate sodium hydroxide (NaOH) or potassium hydroxide (KOH) or a combination of both.
The Guild has licensed with the American Oil Chemist's Society to use the SAP values they have determined as standards for the oils. Since all oils vary from location to location and year to year, the AOCS provides a range of of acceptable values for each oil. In the HSMG Lye Calculator, you will see what those ranges are and what number is being used in the calculations. You will have the option to change the SAP value being used if you know the actual SAP value of the oil you have.

While there have been lye calculators available, there's never one like the new HSMG Lye Calculator when it comes to providing you with all the information and calculations you need to make the best possible batch of soap.

If you are not already a member of the Soap Guild, I encourage you to join! The Guild offers many valuable services designed specifically for those in the soap making industry. If you are already a member of the Guild, you can check out the Lye Calculator by logging in to the member area and you'll see a link in the top left menu bar.

There is also a non-member version of the HSMG Lye Calculator available in the "Industry" section of the website. It doesn't allow for specification of an exact SAP value and a few other things, but it's still a great lye calculator. This is an incredible tool for those of you making Cold Process or Hot Process soaps. I hope you take advantage of this FREE tool.
