Ouricuri Oil

INCI Syagrus Coronata Seed Oil. Also: Licuri oil, Ouricury oil, Licuri kernel oil, Syagrus coronata seed oil, Syagrus coronata kernel oil.

Calculate a 100 % Ouricuri Oil bar

The saponification value here is derived, not published. No primary document we could use gives one for Ouricuri 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 247.0 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.

A lauric kernel oil, close to coconut and babassu. Antoniassi, Miranda, Ferreira, Vieira, Freitas & Matsuura 2022 (Food Sci. Technol. 42:e69720; led by Embrapa Agroindustria de Alimentos): kernels from four places in the Sisal Territory, Bahia (Valente, Sao Domingos, Santa Luz, Milagres). Table 3, average +/- SD: C6:0 <=0.36, C8:0 9.2 +/- 2.6, C10:0 6.6 +/- 0.7, C12:0 46.1 +/- 1.1, C14:0 14.6 +/- 1.0, C16:0 6.5 +/- 0.7, C18:0 3.5 +/- 0.6, C18:1 10.3 +/- 1.1, C18:2 2.8 +/- 0.2, C20:0 <=0.06; the text gives the ranges across the samples: lauric 45.5-47.7, myristic 13.7-15.9, oleic 9.1-11.7, caprylic 6.7-11.4, capric 5.7-9.7, linoleic 2.6-2.9. Typical values are the table averages; ranges are the text ranges; palmitic and stearic have no printed range. The same table prints saponification value 247.3 +/- 4.7 mg KOH/g (text: 242-252) and iodine value 13.7 +/- 1.2 (text: 13-15), but the methods state that 'the iodine and saponification indexes were calculated based on the fatty acid composition'. A figure calculated from the composition is not a measurement, so both fields are null and the build derives the value from the same profile, which should land near 247. Corroboration, not merged: Gomes et al. 2026 (Inflammopharmacology 34(7):4721-4731), cold-pressed kernel oil from Capim Grosso, Bahia: caprylic 11.18, capric 6.94, lauric 45.80, myristic 13.60, palmitic 6.30, linoleic 1.40, oleic 13.24, stearic 1.54; PlantFAdb (a 1971 German deacidification paper): C8:0 10.0, C10:0 9.0, C12:0 46.0, C14:0 9.0, C16:0 8.0, C18:2 3.0, C18:1 13.0, C18:0 2.0. Bauer et al. 2013 (Acta Sci. Technol. 35(4):771-776) state lauric 43.4/44.2, myristic 13.89/14.45, oleic 12.83/12.08 and palmitic 6.87/6.92 % for refined and pressed licuri oil, but print the full table in mg/g with misaligned rows; it was not transcribed. Ouricury wax is a leaf wax with its own INCI name and is a different product.
