A bar made of 100 % Palm Kernel Olein
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.

Where these numbers come from
Verbatim mirror of the FAO file CXS_210e.pdf; the official FAO link was Cloudflare-gated at retrieval. Table 1 (Section 3.1) = mandatory GLC fatty-acid ranges, % of total fatty acids, ND = not detectable (<=0.05%). Table 2 (Appendix 'Other quality and composition factors') gives saponification value, iodine value (Wijs) and unsaponifiable matter of CRUDE oils; the Appendix is explicitly ADVISORY (a product not meeting it may still conform). This print predates the 2021-2025 amendments; the 2024 additions (avocado, camellia seed, sacha inchi, high-oleic soya bean) are not included.
Fatty acids from CXS 210 Table 1 (mandatory GLC ranges, % of total fatty acids; 'ND' = not detectable, <=0.05%, entries that are ND-only are omitted; C17:0, C17:1, C20:2, C22:2 and C24:1 columns omitted because they are outside the acids this database records). The saponification value, the iodine value and the unsaponifiable share from Appendix Table 2 (crude oils; ADVISORY, not mandatory; unsaponifiable converted from g/kg). No 'typical' values are printed in the standard, so none are given. Section 3.2 slip point: between 21 and 26 C (mandatory). Unsaponifiable printed '<15' g/kg.
