Hazelnut Oil
INCI Corylus Avellana Seed Oil. CAS 84012-21-5, 185630-72-2; EC 281-667-7, as CosIng gives them. Also: Corylus avellana kernel oil, Filbert oil.
Published values
| Saponification value | 188–198 mg KOH/g |
| Used by the calculator | 193.0 mg KOH/g (midpoint) |
| SAP for NaOH | 0.1376 g/g |
| Iodine value | 81–95 g I₂/100 g |
| INS (SAP − IV) | 105 |
| Melting point | — |
| Unsaponifiable matter | ≤ 1.5 % |
Soapmaking books print about 0.136 g NaOH per g (median of 7 books), which agrees with ours to within 2 %.

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. Hazelnut oil was added to CXS 210 in the 2019 revision.
