Olive-Pomace Oil (refined / blended)
Also: Refined olive-pomace oil, Olive pomace oil, Sansa oil, Sulphur olive oil.
Published values
| Saponification value | 182–193 mg KOH/g |
| Used by the calculator | 187.5 mg KOH/g (midpoint) |
| SAP for NaOH | 0.1337 g/g |
| Iodine value | 75–92 g I₂/100 g |
| INS (SAP − IV) | 104 |
| Melting point | — |
| Unsaponifiable matter | ≤ 3 % |
Soapmaking books print about 0.134 g NaOH per g (median of 2 books), which agrees with ours to within 2 %.
A bar made of 100 % Olive-Pomace Oil
Conventional qualities summed from the fatty-acid groups; a single-oil bar is a reference point, not a recipe.

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.

Compared with other oils
Where these numbers come from
Section 3 fatty-acid composition (GC, % total FA) is mandatory. Appendix 3 'Chemical and physical characteristics' (relative density 0.910-0.916, saponification value, iodine value (Wijs), unsaponifiable matter) is ADVISORY. C18:3 limit left open in this print (footnote 3: national limits may remain pending IOOC survey).
Fatty acids: CXS 33 Section 3 table, olive-pomace oil column (same as olive oil except C22:0 0.0-0.3 %). SAP 182-193, IV 75-92 and unsaponifiable <= 30 g/kg from the ADVISORY Appendix. Solvent-extracted from pomace; not an olive oil for labelling purposes (Section 7.1).
