Avocado Oil

INCI Persea Gratissima Oil. Saponified with NaOH it is listed as Sodium Avocadoate, with KOH as Potassium Avocadoate. Also: Persea americana fruit oil, Persea gratissima oil.

Calculate a 100 % Avocado Oil bar

The saponification value here is derived, not published. No primary document we could use gives one for Avocado 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 194.0 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.

Avocado oil was added to Codex CXS 210 in 2024 (CAC47) but the current FAO print could not be retrieved (Cloudflare-gated), so the Codex ranges are not used. Values are the DAC (Deutscher Arzneimittel-Codex) 'Avocado oil, refined' limits as transcribed on the Gustav Heess specification sheet: iodine value 75.0-95.0; unsaponifiable max 2.0 %; acid value max 1.0; <C16 max 2.0, palmitic 5.0-25.0, palmitoleic 1.0-12.0, stearic max 3.0, oleic (+isomer) 50.0-74.0, linoleic 6.0-20.0, linolenic max 3.0, other FA max 1.0 %. sapKohMgPerG is NULL: no saponification value is printed on the sheet or in any other primary document I could open. The cold-pressed sheet (Sp204020b) gives the same FA ranges (palmitoleic 1.0-13.0) and no SAP/IV.
