Soapmaking books print about 0.139 g NaOH per g (median of 7 books), which agrees with ours to within 2 %.
A bar made of 100 % Macadamia Nut 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.

Where these numbers come from
Full-text PDF. Table 2 = PV, free acidity, iodine value, saponification value, oxidative stability for treatments SP/HP/MSP/OSP/MHP/OHP; Table 3 = fatty-acid profile (%).
Table 4 (raw nuts, M. tetraphylla, China): source of arachidic, behenic and lignoceric values; Table 2 acid/peroxide values.
Primary source (Ribeiro et al. 2020, Emirates J. Food Agric.) pressed commercial Macadamia integrifolia nuts bought in Lavras (MG, Brazil) six ways (screw or hydraulic press, with/without microwave or oven pre-treatment). Table 2: iodine value 77.7-82.7 g I2/100 g and saponification value 194.3-195.8 mg KOH/g across the six oils (no mean printed); peroxide value 0.81-6.33 meq O2/kg; free acidity 0.36-0.67 % oleic. Table 3 fatty-acid profile (%) gives the min/max used here for myristic, palmitic, palmitoleic (C16:1n7), stearic, oleic, linoleic, gondoic/gadoleic (C20:1n9) and alpha-linolenic (0.13-0.15 % in screw-press oils but 2.29-2.38 % in hydraulic-press oils; transcribed as printed, the spread is unexplained in the paper). The paper itself quotes Moodley et al. 2007 (SAP 193.7 mg KOH/g, IV 78.3) and Navarro & Rodrigues 2016 (IV 72-78) as literature comparisons. Arachidic (2.25-2.93 %), behenic (0.61-0.73 %) and lignoceric (0.35 % in one variety, ND in the other, so only a max is given) are NOT in the primary paper; they come from the additional source Tu et al. 2021 (Food Sci. Nutr., Table 4, raw Macadamia tetraphylla varieties 'Guire 1' and 'Own Choice' grown in China), whose other values fall within or close to the primary ranges (myristic 0.34-0.57, palmitic 8.16-8.86, palmitoleic 18.73-19.76, stearic 3.13-3.43, oleic 59.65-61.18, linoleic 2.26-2.87, gondoic 2.02-2.17 %). Tu et al. report acid value 0.64-0.76 mg KOH/g and PV 0.19-0.34 meq/kg but no SAP or IV. Melting point and unsaponifiable matter: not reported by either source. INCI name from CosIng. INCI: CosIng carries three names a supplier may use for macadamia oil: Macadamia Integrifolia Seed Oil, Macadamia Integrifolia/Tetraphylla Seed Oil, and Macadamia Ternifolia Seed Oil. Use the one on your supplier’s documents.
