What is superfat or discount, and why is a minimum 5% discount recommended?

If you use all the lye necessary to exactly saponify all of the fatty acids in the oils, the soap would have no excess lye or excess oil (next to impossible without a chemistry lab). It would have a zero discount and there would be no superfat. If you discounted the lye, let's say by 5%, 5% of the soap would contain oils that have not chemically reacted with the lye. i.e. all the lye was used up in reacting with 95% of the oils. The soap would have a 5% superfat. These unspecified oils are good for conditioning the skin. A soap with no discount or superfat will clean better. However, other than conditioning the skin, there are other important reasons to discount the lye (or superfat the soap). Please see the next question.

The SAP values used to calculate the amount of lye - in this calculator and in others - is an average. If you purchase oils/fats that have been assayed by a chemical lab, you will know the exact SAP value of the oils/fats. (Your wallet will be a little thinner too). If you weigh these oils and the lye on very precise laboratory scales, you can confidently make a true zero discount soap.

One of my references gives the Potassium Hydroxide (chemical symbol KOH) SAP value for coconut oil as 250-264. The SAP for other oils is specified similarly as a range of values. Why? There are many variables that contribute to the chemical qualities of a carrier oil. Here are a few to give you the general idea:

Species of the botanical used to make the oil.
Geographical location of the source botanical. i.e. variable climate.
Varying types of processes used to create the oil.
Seasonal differences in when the botanical was harvested.
Maturity of the botanical when it was harvested.

The minimum 5% discount/superfat is recommended to allow for these variances so you do not end up with soap that contains unused lye.

Column Swirl Tutorial

I was on You Tube looking at videos for bath bomb machines that I was considering buying, and found this by accident. All I could say is WOW. Hill Country Haiku does an amazing job with her column swirl. I think I'm going to try this method this week, and keep you guys posted. Now all I need to do if find these wooden dowels so I can do the same. Wish me luck.

It's been forever since I last posted, but this is worth he wait. For all of you soapmakers out there, that want to take there business to the next level. This is made for you.

I love to look for other handmade or natural soaps on the market and I stumbled across True Body Products. I went through her website, and was very impressed that she only sold one kind of soap, and she was thriving in her business. I was even more amazed at how The New York Times wrote many articles on her. This is a great read for any one who wants to learn how to turn there business into something big, especially us soapmakers.
