Turning a recipe into a product
Updated
The step between making soap you like and having something you can sell repeatedly.
A recipe is not a product
A recipe says what goes in. A product says what comes out, every time, at a stated weight, with a stated name and a settled category.
Which is why the bar you made and loved is usually several months from being a line.
The work between them is standardization, not creativity.
Fix the recipe
Lock the oil percentages, the superfat, the water ratio and the fragrance rate, by weight.
Run it by percentage rather than by absolute quantity, so it scales without recalculating from scratch.
Recheck the lye quantity against the specific oils you buy rather than a generic table, and recheck it when a supplier changes.
Then leave it alone for several batches, because a recipe changed every batch is never characterized.
Fix the process
The same temperatures, the same trace, the same insulation decision, the same mold, the same cut.
Write the process down as steps with numbers in them, because "when it looks right" does not transfer to another day or another person.
That written process is what makes batch 80 match batch 1, and it is the thing wholesale buyers are actually buying.
Fix the record
Batch number, date, recipe version, lots for oils, lye and fragrance, cure start, cured weight, and how many bars were sellable.
That last figure is your real yield and it is usually lower than you assume.
And the cured weight is what goes on the label, which is the point where this page and the labeling requirement meet.
