The soap qualities are derived from the fatty-acid profile, which is below. They are shown here only for records the calculator can use.
How much lye
| Oil | NaOH | KOH |
|---|---|---|
| 500 g | 63.5 g(59.3–67.7) | 89.1 g(83.1–95.0) |
| 1 kg | 127.0 g(118.5–135.4) | 178.1 g(166.3–190.0) |
| 1 lb (454 g) | 57.6 g(53.8–61.4) | 80.8 g(75.4–86.2) |
| 2 lb (907 g) | 115.2 g(107.5–122.9) | 161.6 g(150.8–172.4) |
For this oil alone at 5 % superfat, with pure sodium hydroxide (NaOH) or pure potassium hydroxide (KOH); in brackets, across the published range of its saponification value. KOH is usually sold at 90 %: divide by 0.9. For a whole recipe, open the calculator.

Where these numbers come from
Mirror site hosting the USP 29-NF 24 text; values transcribed from that page. Newer USP editions may differ.
JP XVIII 'Hydrogenated Oil': fat obtained by hydrogenation of fish oil or other animal/vegetable oils; acid value NMT 2.0.
USP 29-NF 24 'Hydrogenated Vegetable Oil': a mixture of triglycerides of fatty acids; Type I: melting range 57-85 C, iodine value 0-5, saponification value 175-200; Type II: melting range 20-50 C, iodine value 55-80, saponification value 175-200; acid value NMT 4.0; unsaponifiable NMT 0.8 %. The the iodine value and the melting point fields span both types (Type I: IV 0-5, m.p. 57-85 C; Type II: IV 55-80, m.p. 20-50 C). Source oil is not specified, so no fatty-acid ranges. JP XVIII 'Hydrogenated Oil' (fish or animal/vegetable origin): acid value NMT 2.0 (other JP limits not transcribed).
