I love the idea of a 15% superfat for a facial bar!

The project is providing superfast broadband to areas without commercial rollouts. These are areas that telecoms companies have decided aren’t economical to rollout to. This covers over half of all premises in Wales.

To figure out a superfat, you can do it a few different ways. My favorite is to let the figure it out for you (!) or you can take the amount of lye that you are supposed to use and multiply it with the following equation (1 – % superfat you want). So, if you wanted to superfat your Olive Oil soap in the above example by 4%, you would do the following (.134 oz. lye) x (1 – .04) = .1286 oz. lye. Or you can do the rough ‘n’ easy way; for a one pound batch of soap, a 5% superfat works out roughly to .8 oz. of extra oils per pound of soap.

Let’s calculate the superfat of my soap under these two scenarios:

  1. By superfatting you can sometimes control which oils will saponify and which not
  2. There is an important and non-trivial difference in the calculation of the superfat percentage between the two methods

3) The final superfat is calculated as 1 – B/A

When I superfat my cold process soap I normally keep my superfat to 5% or less. I find that much more than that and my soaps are a wee bit soft, don’t lather quite as much as I like and also tend to go rancid more quickly. That said, superfat is a totally personal thing. I know some soapmakers that go up to 15% and swear by it. I’d recommend experimenting a bit until you find the amount you love. Soapmakers, I’d love to get your opinion on what your favorite superfatting range is.
