Sunflower Seed Oil - High Stearic, High Oleic
INCI Helianthus Annuus Seed Oil. Saponified with NaOH it is listed as Sodium Sunflowerseedate, with KOH as Potassium Sunflowerseedate. CAS 84776-03-4, 8001-21-6, 164250-88-8; EC 232-273-9, as CosIng gives them. Also: High stearic high oleic sunflower oil, HSHO sunflower oil, High-oleic high-stearic sunflower oil.
Calculate a 100 % Sunflower Seed Oil - High Stearic, High Oleic bar
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 36 Codex oils where both fields come from the same standard, the method's median error is 0.84 % and its 90th percentile 2.44 %, and it runs slightly high, by 0.55 % on average. 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.

Where these numbers come from
Table 2, oil HO20 before interesterification: fatty acids (% w/w) and iodine value.
High-stearic high-oleic (HSHO) sunflower oil comes from sunflower lines that accumulate stearic acid as well as oleic acid. Figures: Salas, Martinez-Force, Bootello and Venegas-Caleron 2026, Foods 15:1784, Table 2 'Composition of the fatty acid, iodine value (IV) and triacylglycerol (TAG) classes of the high-stearic-high-oleic oils used in this work', oil HO20 (native, before enzymatic interesterification), % w/w: 16:0 5.9, 18:0 19.5, 18:1 67.0, 18:2 4.7, 20:0 1.3, 22:0 1.6, iodine value 65.8; TAG classes SUS 16.4, SUU 53.6, UUU 30.0 %, trisaturated 0.0 %. The table's header prints '20:0' twice; the second is 22:0, as the same paper's Tables 5 and 6 label that column. Means of three technical replicates. The paper's second oil, ML22, is a mid-oleic high-stearic line (16:0 6.0, 18:0 22.1, 18:1 54.0, 18:2 13.9, 20:0 1.8, 22:0 2.2, IV 70.5) and is not merged: it is a different oil type. This is one analysed oil, not a trade range; commercial HSHO lots vary with genotype and growing temperature. NO SAPONIFICATION VALUE is published for HSHO oil in any document opened, so the saponification value is blank and the build derives one from the profile (all C16-C22, close to ordinary sunflower). No melting point was measured on the whole oil (the paper's DSC data are for fractionated stearins), so the melting point is blank. The INCI name and identifiers are those CosIng gives for sunflower seed oil, which do not distinguish varieties.
