Black Magic (soap)

Currently in France and my father introduced my to this new kind of soap that destroys oil based substances. It's called Black Soap (savon noir) see pics attached.
An example of its amazing-ness... I was working on my dads bike to try to clean it up, front sprocket area and of course i got a bunch of oil on my hands.
Added a bit of this soap and a bit of a rub and done. Similar effects as if i was washing with kerosene, but not as bad on the hands.

Seems this soap is 100% natural, based on olives or something, has anybody heard of it?

None the less I'll give the bike a scrub down with a tooth brush and this oil and then rinse it all off, see what happens...

Not sure, some quick searches didn't really produce much.

For those who know a bit of chemistry:
"Le savon est un produit liquide ou solide composé de molécules amphiphiles obtenues par réaction chimique entre un corps gras et une base forte, spécifiquement l'hydroxyde de sodium pour le savon ou l'hydroxyde de potassium pour le savon noir, c'est donc le sel d'un corps gras"
in English:
Soap is a liquid or solid product composed of amphiphilic molecules obtained by chemical reaction between a fatty substance and a strong base, specifically sodium hydroxide for soap or potassium hydroxide for black soap.

I highlighted in red, it seems it's based on potassium hydrooxide:
Potassium hydroxide is an inorganic compound with the formula KOH, and is commonly called caustic potash.
Along with sodium hydroxide (NaOH), this colorless solid is a prototypical strong base. It has many industrial and niche applications, most of which exploit its corrosive nature and its reactivity toward acids.

Here in France, it seems the uses for the black soap:
- clean conrete, ground etc
- around the kitchen, washing and shining
- clean glass, leather, oil stains on any surface
- interiour and exteriour car wash
- can be used to clean tools

Seems like a general purpose oil remover type soap, ok for metal applications, but I haven't found anywhere uses on rubber/effects on rubbers/plastics...

I guess we'll see....
