As little as an ounce of rosin in a 5 lb batch boosts lather.Can 'Pine Rosin' be used in soap making?
No. Think of Pine Tar as an additive. Although it is listed, it has no FA (Fatty Acids) so it looks like this on the print out.Can it replace 'Pine Tar'?
This is true. To make it easier to work with, I buy rosin powder or grind the rock type to a fine powder in a dedicated food processor. It is sticky (think tree sap) and has a high melting point. Once melted, it's difficult to get it out of the container once it cools. So, I melt it down with an equal amount of coconut oil, pour into individual round cavity molds; freeze for an hour; pop the disks out and freeze them in a ZipLoc bag until I need one.Rosin is really tricky to include as an ingredient -- even more so than pine tar
It is worth the time and trouble if you want to design your own soap. MMS (Majestic Mountain Sage) is good for making a "tried and true" soap recipe. If you want to formulate your own recipe you will want to use one of the others. Here's a link for a brief explanation on how I go about it. I always caution Newbies to take a cuppa with them to play -- the hours pass quickly! You can learn a lot there by using your mouse to hover over each number and the various subjects on the page.obsidian, thank you, I have been using Majestic Mountain, I do not know how to use Soapcalc yet, I guess I need to sit down and figure that one out.
