The Big Book of Homemade Products is the combined edition: it carries the whole soap book and the nine face formulas from the skin care book in one volume, for $59.99 instead of the $39.99 + $39.99 the two cost separately.
Only want one formula? Single chapters are $9.99 each.
INCI names, not marketing names, with the function of each one spelled out — so you can buy the right raw material and know what it is doing in the formula.
Each formula is a phase table with weight percentages for a stated yield, the order of addition, and the temperature every step happens at.
A target pH, the acid used to reach it, a named broad-spectrum preservative and a shelf life. The parts most recipe blogs leave out are the parts that decide whether a product is safe.
Why soap seizes, why a cream separates, why a candle tunnels, why a shampoo goes thin. Each book explains the failure as well as the method.
