Toilet bars
Toilet soap on hardened fish oil, I
This one names a fat the database does not carry yet, so the numbers below are not computed. The fats a recipe wants and we lack are what decides which ones get added next.
The oils
| Oil | As the source prints it | Share |
|---|---|---|
| Edible Tallow (beef/mutton dripping) | Tallow · 45 parts | 45.0 % |
| Talgol · not in the database yet | 40 parts | 40.0 % |
| Coconut Oil | Cocoanut Oil · 15 parts | 15.0 % |
How it is made
| Process | Full-boiled |
| Alkali | Not stated |
| Superfat | Not stated |
| Water | as the source states it |
This is a boiled soap. A kettle soap has its excess alkali salted out and drawn off before framing, so the recipe states the alkali charged, never the alkali the bar keeps. Read as a modern cold-process recipe it would be lye-heavy.
What the numbers say
This one cannot be computed yet: it names Talgol, which the ingredient database does not carry.
The source
Talgol is a trade name the book itself glosses as "undoubtedly hardened fish oil" — a reminder that a 1920s trade name is not a specification.
