A bar made of 100 % Cohune Oil
Conventional qualities summed from the fatty-acid groups; a single-oil bar is a reference point, not a recipe.

A lauric kernel oil from the Central American cohune palm, in composition close to babassu (same genus). No modern journal paper with a full analysis could be opened, so the record rests on PlantFAdb's transcriptions of four older sources: Attalea cohune (plant 11576): 'Fette und Lipoide (Lipids)' (Springer, 1969; SOFA TAB_003197): C6:0 0.0, C8:0 7.5, C10:0 6.5, C12:0 46.5, C14:0 16.0, C16:0 9.5, C18:2 1.0, C18:1 10.0, C18:0 3.0; 'Some new oil-seeds derived from American palms' (1916; TAB_003194): C8:0 8.0, C10:0 7.0, C12:0 46.0, C14:0 16.0, C16:0 9.0, C18:2 1.0, C18:1 10.0, C18:0 3.0. Attalea cohune (plant 14271; TAB_008357 and TAB_009872, kernel oil, oil content 65.8 %, remarks 'vide Orbygnia cohune' and 'Nigeria', publication listed as 'Development of Tucum pulp oil fractions for possible edible and industrial use' (1988)): iodine value 18.9, saponification value 241.2, C8:0 4.0, C10:0 6.0, C12:0 42.4, C14:0 18.7, C16:0 8.3, C18:2 3.6, C18:1 14.9, C18:0 2.1. Orbignya cohune (plant 12322): 'Seed lipids of the palm family' (1979; TAB_006540): C8:0 7.0, C10:0 5.9, C12:0 50.8, C14:0 18.4, C16:0 9.0, C18:2 0.0, C18:1 5.6, C18:0 3.2; oil content 52.2 % ('Analyses of seed samples from 113 plant families', 1962). The only saponification/iodine pair comes from the 1988 entry, whose metadata suggest the cohune figures were quoted in a paper about another palm; the pair agrees with its own composition (which implies about 238 mg KOH/g and about 19 g I2/100 g), so it is used, with that caveat. PlantFAdb labels every value 'GLC-Area-%', including the 1916 figures, which must predate gas chromatography. The ranges are min/max over the four compositions; no typical is given.
