Aloe butter (coconut oil + aloe blend): SAP value and fatty acids
Aloe butter (coconut oil + aloe blend) has a saponification value of 245.4 mg KOH/g. One gram needs 0.175 g of sodium hydroxide (NaOH) for bar soap or 0.245 g of potassium hydroxide (KOH) for liquid soap to turn fully into soap, before any superfat.
Key numbers
- SAP, NaOH
- 0.174941 g per g oil
- SAP, KOH
- 0.2454 g per g oil
- Saponification value
- 245.4 mg KOH/g
- INCI name
- Cocos Nucifera Oil + Aloe Barbadensis Leaf Extract
Example: 100 g of Aloe butter (coconut oil + aloe blend) with no superfat needs 17.5 g of 100% NaOH, or 24.5 g of 100% KOH. A 5% superfat uses 5% less.
In soap
Aloe butter (coconut oil + aloe blend) is left out of the soap-quality scores in Soap Ledger: it is mostly not ordinary oil (a wax, resin, blend or an oil with unusual fatty acids), so those scores would not describe it. It still counts fully in the lye calculation.
Usually coconut oil (sometimes hydrogenated) with aloe extract, so it behaves like coconut oil. Base varies by maker; check the COA. Published sources for this oil differ by more than 3%, so checking your supplier's certificate of analysis matters more than usual.
Sources
SAP value: 245.4 mg KOH/g (Median of sources), from Saponification Chart, From Nature With Love (soap/cosmetic supplier). Printed value: 220 - 260 mg KOH/g.
Published values we checked:
- 220 - 260 mg KOH/g — From Nature With Love (soap/cosmetic supplier)
- NaOH 0.1788 / KOH 0.2518 g alkali per g oil — Certified Lye
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.
