Yes, I own just about every soap making book on the market today. No, none of them tell you how to titrate your oils. This book does. It also tells you how to measure properly, how to test your bars for various qualities, what to do to avoid the dreaded orange spots, and why it's a waste of time adding "superfatted" oils to your soap last.
There is so much more in here but it is definitely for the chemistry lover. If you just want to make a bar of soap, you can do that with almost any soap making book. If you want to standardize your bars so that you know exactly what you are getting each and every time, this is the book you would buy.
The last half explains a few experiments he did to test various qualities in soap like whether there is a difference in a lye discount and superfatting. I found the explanation of soap curd vs neat soap to be very interesting and the experiment on melted soap vs unmelted in water was enlightening. This is a book I recommend you read if you want to know more about making soap than what you'd find in a youtube video.
The book starts with basic protocols on weighing, chemical handling, and supplies for your soapmaking lab. And then follows with in-depth information on oils and their structures, acid and bases, saponification stoichiometry, and analytical techniques to test your starting materials and soap. These are all tools for you to bring into play when addressing an issue in the soap pot, formulating a recipe with new oils or additives, or troubleshooting finished soap issues.
The last section, research and development, leads you through five research projects conducted by Dr. Dunn and his students at Hampden-Sydney College to answer long-standing questions asked in the cold-process handcrafted soap community: causes of the dreaded orange spot, effect of time and temperature on saponification, effects of lye and water discounts, and factors that affect trace. This last section is what makes this book so unique and valuable for a cold-process handcrafted soapmaker - the problem is defined, a scientific approach is composed, tests are run, and the data is analyzed and discussed.
"Scientific Soapmaking" fills a knowledge gap for the cold-process handcrafted soap community and I recommend it as a great resource for all handcrafted soapmakers.
