Algal Oil - High Oleic (Prototheca moriformis)
INCI Prototheca Moriformis Oil. Also: High oleic algal oil, High-oleic algae oil, HO algal oil, High oleic microalgae oil.
Calculate a 100 % Algal Oil - High Oleic (Prototheca moriformis) 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 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 bar made of 100 % Algal Oil - High Oleic (Prototheca moriformis)
Conventional qualities summed from the fatty-acid groups; a single-oil bar is a reference point, not a recipe.

Where these numbers come from
Producer's specification (Table 2, notice page 6 of 51) and three-lot fatty acid composition (Table 3, page 8 of 51), read from the page images of the scanned PDF.
FDA summary: strain S6697 produces approximately 3 % palmitic, 2 % stearic and 90 % oleic acid; FDA had no questions about the GRAS conclusion.
A triglyceride oil made by fermentation: the microalga Prototheca moriformis (strain S6697, 'modified via classical mutagenesis and targeted genetic modification' in the notice's words) grown in culture on sugar; the oil is refined, bleached and deodorised. Figures are the producer's own, from the GRAS notice TerraVia Holdings (now Corbion) filed with the US FDA as GRN 754 (FDA letter of no questions, 2018). Table 3, fatty acid composition, % of total fatty acids (area %), three lots RBD750 / RBD850 / RBD854 / mean: C10:0 0.01 / 0.02 / ND / 0.02; C12:0 0.02 / 0.03 / 0.03 / 0.03; C14:0 0.38 / 0.37 / 0.42 / 0.39; C15:0 0.01 / 0.01 / ND / 0.01; C16:0 3.87 / 3.02 / 3.72 / 3.54; C16:1 0.18 / 0.14 / 0.13 / 0.15; C17:0 0.04 / 0.04 / 0.05 / 0.04; C17:1 ND / 0.03 / 0.05 / 0.04; C18:0 3.73 / 3.99 / 3.27 / 3.67; C18:1 88.70 / 87.89 / 88.22 / 88.27; C18:2 0.99 / 1.68 / 1.93 / 1.53; C18:3 alpha 0.17 / 0.16 / 0.27 / 0.22; C20:0 0.25 / 0.34 / 0.26 / 0.28; C20:1 0.28 / 1.07 / 0.73 / 0.84; C22:0 0.05 / 0.07 / 0.06 / 0.06; C22:1 ND; C24:0 0.02 / 0.05 / 0.04 / 0.04; total identified 98.70 / 98.91 / 99.18 / 99.08. Min/max are the three lots and typical is the printed mean; C15:0, C17:0 and C17:1 have no schema key. Two printed means do not equal the average of the printed lots - C18:3 (lots average 0.20, and the notice's own Table 2 prints 0.20 as the average) and C20:1 (lots average 0.69) - they are transcribed as printed. Table 2 specification (with the three-lot range and average): oleic >= 80 area % (87.89-88.70, avg 88.27), linoleic <= 10 (0.99-1.93, 1.53), alpha-linolenic <= 0.8 (0.16-0.27, 0.20), total saturated fat <= 15 (7.85-8.38, 8.06), free fatty acids <= 0.1 % (0.03), moisture <= 0.1 %, unsaponifiable matter <= 1.0 % (0.20-0.70 %, avg 0.37 %, AOCS Ca 6a-40; stored), peroxide value <= 5 meq/kg, p-anisidine <= 10. The same table also carries the earlier strain S2532 oil of GRN 527 (mean: palmitic 8.11, stearic 1.55, oleic 86.66 %), a different, higher-palmitic product, not merged. NO SAPONIFICATION OR IODINE VALUE appears anywhere in the 139-page notice, so both are null and the build derives the saponification value from the profile. At about 88 % oleic acid its composition sits inside the range CXS 210 sets for high-oleic sunflower seed oil (C18:1 75-90.7 % in the current print). INCI: CosIng's 'Prototheca Moriformis Oil' ('the oil derived from the alga, Prototheca moriformis, grown in culture') names this organism and process; CosIng gives no CAS or EC number for it. Note that the personal-care grade of Corbion's high-oleic algal oil (AlgaPur HSHO, distributed by Lubrizol) is sold under the INCI name Triolein, a separate CosIng entry; that product is a different grade and this record does not describe it.
