Mango seed oil (liquid fraction): SAP value and fatty acids
Mango seed oil (liquid fraction) has a saponification value of 191.5 mg KOH/g. One gram needs 0.137 g of sodium hydroxide (NaOH) for bar soap or 0.192 g of potassium hydroxide (KOH) for liquid soap to turn fully into soap, before any superfat.
Key numbers
- SAP, NaOH
- 0.136517 g per g oil
- SAP, KOH
- 0.1915 g per g oil
- Saponification value
- 191.5 mg KOH/g
- INCI name
- Mangifera Indica Seed Oil
Example: 100 g of Mango seed oil (liquid fraction) with no superfat needs 13.7 g of 100% NaOH, or 19.2 g of 100% KOH. A 5% superfat uses 5% less.
In soap
We don't have a sourced fatty-acid profile for it yet, so Soap Ledger shows no soap-quality scores for recipes that use it. The lye calculation still works.
Soap suppliers sell the softer, liquid fraction of mango kernel fat as 'mango seed oil'. No source specific to the liquid fraction was found; the figures are for whole mango kernel fat, which has similar chain lengths. Use the supplier COA.
Sources
SAP value: 191.5 mg KOH/g (FSSAI range midpoint (mango kernel fat)), from Mango oil (Wikipedia article, citing SEA Hand Book 2009, Solvent Extractors' Association of India), Wikipedia. Printed value: 190.1–195.1 mg KOH/g.
Published values we checked:
- 185-198 mg KOH/g — Food Safety and Standards Authority of India (FSSAI)
- 190.1–195.1 mg KOH/g — Wikipedia
NaOH and KOH values are converted from mg KOH/g with the molar masses 39.997 and 56.106 and rounded to 6 decimals, exactly as in the Soap Ledger app. Real oils vary by origin, grade and lot: check your supplier's certificate of analysis. Verify every weight before you make this, and follow lye safety. Not a safety or compliance certification.
