Inajá Kernel Oil
INCI Attalea Maripa Seed Butter. Also: Inaja kernel oil, Inaja butter, Inaja kernel fat, Attalea maripa seed butter, Maximiliana maripa kernel oil, Maripa fat.
Calculate a 100 % Inajá Kernel Oil 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.

One soapmaking book prints 0.184 g NaOH per g. No soapmaking book we read gives inajá kernel oil a figure, and the measurements that exist disagree with each other and with the oil's fatty acids. We work it out from those fatty acids, which make it a lauric fat like babassu, at 244 mg KOH/g (0.174); one 1903 analysis found 260, so if anything this errs toward superfat.

For this oil alone at 5 % superfat, with pure sodium hydroxide (NaOH) or pure potassium hydroxide (KOH); in brackets, across the published range of its saponification value. KOH is usually sold at 90 %: divide by 0.9. For a whole recipe, open the calculator.

Where these numbers come from
Dataset #14303, kernel oil (SOFA TAB_014601).
The kernel fat of the inaja palm, a lauric fat like babassu from the same genus; CosIng's only inaja ingredient is this one, Attalea Maripa Seed Butter. The pulp oil is a different, oleic product (inaja-oil). ONE ANALYSIS ONLY: Bereau et al. via PlantFAdb ('Maximiliana maripa Drude mesocarp and kernel oils: fatty acid and total tocopherol compositions', 2001; SOFA TAB_014601; French Guiana), kernel oil, oil content 31.3 %: C6:0 0.0, C8:0 3.8, C10:0 4.0, C12:0 40.5, C14:0 25.4, C16:1 0.0, C16:0 9.0, C18:2 2.4, C18:1 10.8, C18:0 2.4 (98.3 %). No saponification value, iodine value or melting point was found in an allowed document; the build derives the saponification value from this profile (it implies about 239 mg KOH/g). The category follows palm kernel and babassu oil in this dataset; CosIng calls the material a butter, and whether it is solid at room temperature was not established from a document.
