While the base (ash in this case) can be locally produced, africa as a continent isn't a big edible oil producer/exporter, and that's usually the expensive part in soapmaking.

And one could argue that plant ash isn't the most sustainable source of base in making soap.

West Africa is the home of the oil palm, and doesn't need to go full Borneo to produce adequate amounts of fat for saponification.

Maybe the home, but that doesn't mean productive. They're not producing enough to export, and seem to even be net importing it:

But maybe not being well represented here indicates a healthy domestic market.

(and this data can be suspect: Netherlands aren't growing any, but might do some processing of some kind or re-export)

https://www.indexmundi.com/agriculture/?commodity=palm-oil shows 84% of production being from Indonesia and Malaysia.

Why would you consider exports a useful metric here? Soap can be manufactured with oil for domestic consumption.
