Yangu oil (cape chestnut): SAP value and fatty acids
Yangu oil (cape chestnut) has a saponification value of 192.5 mg KOH/g. One gram needs 0.137 g of sodium hydroxide (NaOH) for bar soap or 0.193 g of potassium hydroxide (KOH) for liquid soap to turn fully into soap, before any superfat.
Key numbers
- SAP, NaOH
- 0.13723 g per g oil
- SAP, KOH
- 0.1925 g per g oil
- Saponification value
- 192.5 mg KOH/g
- INCI name
- Calodendrum Capense Nut Oil
Example: 100 g of Yangu oil (cape chestnut) 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.
Only one numeric source found. Check your supplier's COA. Only one published source was found for this value; confirm it against your supplier's certificate of analysis.
Sources
SAP value: 192.5 mg KOH/g (Median of sources' mgKoh_mid (no Codex/pharmacopoeia standard found)), from Saponification Chart, From Nature With Love (soap/cosmetic supplier). Printed value: 185 - 200 mg KOH/g.
Published values we checked:
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.
