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

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.
Fatty-acid profile
Saturated : unsaturated 12 : 88
| Fatty acid | Published range, % | Used | |
|---|---|---|---|
| Palmitic acid | C16:0 · saturated | 5.45–7.41 (typical 6.37) | 6.4 |
| Palmitoleic acid | C16:1 | 0.23–0.35 (typical 0.29) | 0.3 |
| Stearic acid | C18:0 · saturated | 2.49–3.17 (typical 2.81) | 2.8 |
| Oleic acid | C18:1 | 25.4–41 (typical 36.7) | 36.7 |
| Linoleic acid | C18:2 | 39.1–46.2 (typical 42.5) | 42.5 |
| α-Linolenic acid | C18:3 n-3 | 0.09–0.43 (typical 0.19) | 0.2 |
| Arachidic acid | C20:0 · saturated | 1.12–1.34 (typical 1.24) | 1.2 |
| Gadoleic acid | C20:1 | 0.34–0.6 (typical 0.48) | 0.5 |
Where these numbers come from
Table 2 (saponification value 184 mg KOH/g, range 180-191; iodine value 120 g I2/100 g, range 118-123; acid value 1.20 mg KOH/g; peroxide value 1.49 mEq O2/kg). Table 3 fatty-acid composition, mean and range across the eight cultivars.
Species: SOUR cherry, Prunus cerasus L. All values are from one open-access study of cold-pressed kernel oil from eight Polish sour cherry cultivars ('Koral', 'Lucyna', 'Montmorency', 'Naumburger', 'Wanda', 'Wigor', 'Wolynska', 'Wroble'); min/max are the across-cultivar range and 'typical' is the eight-cultivar mean as printed (Table 2 for saponification/iodine values, Table 3 for fatty acids). Cherry kernel oil is characterised by a conjugated trienoic acid, alpha-eleostearic acid (C18:3 conjugated, 9,11,13), reported at mean 9.27 % (range 8.00-15.62 %) in the same table; it is NOT included under 'linolenic' (which is alpha-linolenic C18:3 n-3 only, mean 0.19 %). The fatty-acid percentages therefore do not sum to 100 without adding eleostearic acid. Sweet cherry (Prunus avium) kernel oil was not sourced in this session (the open-access OCL 2020 paper on Moroccan P. avium varieties returned HTTP 403 to the fetch tool), so no P. avium values are included. INCI name from CosIng. Unsaponifiable matter and melting point were not reported by the source, left blank.
