Arachis Oil - High Oleic (High-Oleic Peanut Oil)

INCI Arachis Hypogaea Oil. Saponified with NaOH it is listed as Sodium Peanutate, with KOH as Potassium Peanutate. Also: High oleic peanut oil, High-oleic groundnut oil, High oleic arachis oil.

Calculate a 100 % Arachis Oil - High Oleic (High-Oleic Peanut Oil) bar

The saponification value here is derived, not published. No primary document we could use gives one for Arachis Oil - High Oleic (High-Oleic Peanut Oil), so it is calculated from this record's own fatty-acid composition: chain lengths fix the molar mass, which fixes how much hydroxide a gram of fat consumes. That gives 188.6 mg KOH/g, ±3 %.

That is stoichiometry on a measured composition rather than a guess, and it is about as well determined as a published figure: checked against the 35 Codex oils where both fields come from the same standard, the method's median error is 0.90 % and its 90th percentile 2.74 %, with no meaningful bias. The formula page shows the working. If you have a certificate of analysis for your lot, enter its measured value in the calculator and this estimate is set aside.

Table 3, fatty acid compositions (%) of the fat of oil bodies from nine high-oleic peanut cultivars (National and Local Joint Engineering Laboratory for Peanut Genetic Improvement).

Codex CXS 210 has no separate high-oleic arachis column: its single arachis oil column (current print) is wide, C18:1 35.0-80 and C18:2 4.0-43.0, and the existing arachis-oil record carries it. This record gives the narrower composition of high-oleic cultivars, from two open-access analyses from China. Typicals: Li et al. 2023 (Ultrasonics Sonochemistry 100:106604), Table 4, control oil CK (cold-pressed high-oleic peanut oil from cultivar Ji Hua 18, Xinjiang), fatty acids %: C14:0 0.01, C16:0 6.19, C16:1 n-7 0.07, C17:0 0.05, C18:0 2.25, C18:1 n-9 74.55, C18:2 n-6 9.01, C20:0 1.29, C20:1 1.83, C18:3 n-3 0.05, C21:0 0.01, C20:2 0.00, C22:0 2.95, C22:1 n-9 0.15, C23:0 0.03, C24:0 1.59; SFA 14.37, UFA 85.63 %. C17:0, C21:0 and C23:0 have no key. Min/max add Zhang et al. 2026 (Foods 15:177), Table 3, fat Soxhlet-extracted from the oil bodies of nine high-oleic cultivars (Y37, Y65, J16, J572, J6, Z215, G37, H985, K1715), %: C16:0 6.15-7.54, C18:0 1.43-4.37, C18:1 77.14-82.03, C18:2 1.04-4.13, C20:0 0.94-1.95, C20:1 1.30-2.41, C22:0 2.30-3.19, C24:0 1.11-1.77 (no 16:1, 18:3 or 22:1 reported). So oleic acid runs about 75-82 % by cultivar and linoleic falls correspondingly; the most oleic cultivars (above 80 % oleic, linoleic below 4 %) fall outside the Codex arachis column. NO SAPONIFICATION OR IODINE VALUE is published in either paper, so both are null; the build derives the saponification value from the profile. Codex's Appendix values for arachis oil (saponification value 187-196, iodine value 77-107) are not transferred, because they belong to the whole arachis column and the most oleic cultivars here fall outside it. A Korean analysis with physicochemical data (Applied Biological Chemistry 2017, 60:653, cultivar K-Ol, 80.63 % oleic) was read through a subscription and is not cited as a source because it is not open access. The INCI name, CAS, EC and saponified names are those CosIng gives for peanut oil generally (Arachis Hypogaea Oil does not distinguish the high-oleic type).
