A bar made of 100 % Myristic Acid
Conventional qualities summed from the fatty-acid groups; a single-oil bar is a reference point, not a recipe.
How much lye
| Oil | NaOH | KOH |
|---|---|---|
| 500 g | 83.6 g(83.0–84.3) | 117.3 g(116.4–118.3) |
| 1 kg | 167.3 g(165.9–168.6) | 234.7 g(232.8–236.6) |
| 1 lb (454 g) | 75.9 g(75.3–76.5) | 106.4 g(105.6–107.3) |
| 2 lb (907 g) | 151.8 g(150.5–153.0) | 212.9 g(211.2–214.6) |
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 100 : 0
| Fatty acid | Published range, % | Used | |
|---|---|---|---|
| Lauric acid | C12:0 · saturated | ≤ 2 | 2.0 |
| Myristic acid | C14:0 · saturated | ≥ 98 | 98.0 |
| Palmitic acid | C16:0 · saturated | ≤ 2 | 2.0 |

Producer specification for Wilmar WILFARIN MA-1498 (Myristic Acid 98%): acid value 244-248 mg KOH/g, saponification value 245-249 mg KOH/g, iodine value 0.5 max (% I2 absorbed = g/100 g), titre 53-55 C, colour 0.2/2 max (Lovibond R/Y), composition C12 2 % max, C14 98 % min, C16 2 % max, others 1 % max. Free fatty acid: SAP is essentially the acid value; use directly for lye calculation. Titre 53-55 C is a solidification point, not a melting point, so the melting point is blank. Wilmar's brochure lists the same limits for MA-1498 and the 99 % grade MA-1499. INCI and salt names are the standard CosIng entries, not re-verified on CosIng in this session.
