French term or phrase: Acide de soude
I am not sure of the correct translation. It is in a context of an artisan soap brand that only use natural (vegetal) products.
Context: Je mélange les huiles avec de l'acide de soude. Ça crée la pâte à savon que je vais verser dans 2 gros moules.

Thank you for your suggestions.

Asker: Thank you very much, DLyons! (to my disappointment, it's impossible to make soap otherwise:) )

agree  Charles Davis: True. I was going to post caustic soda but took a bit too long to assemble some evidence. It is odd to call a strong base an acid, but there we are.
5 mins
  -> Thanks Charles. I imagine it's the fact that it burns the skin like an acid would.// As you say in your note :-)

agree  Philippa Smith: bit more research, and I can see it is indeed - not bicarb (seems to be a minor/possible ingredient)

  -> Thanks Philippa.

agree  Tony M: I can confirm that over here in France, caustic soda is often inaccurately referred to as 'acid' in several fields

Asker: Thank you Kashew and Philippa. I'm out at sea, so please post the answer. I was astonished not to find it exactly anywhere...

Asker: Sorrry, more context: Et au bout de 4-6 semaines, le PH redescend, le savon n'est plus caustique et il devient utilisable et vendable.

Asker: I am wondering if (with all the almost 100% natural ingredients) we have caustic soda there...

agree  Philippa Smith: sounds likely given the context (a usual natural soap ingredient), you should post bicarb as an answer / Me too - along with maths, biology, geography...lucky there are languages!

  -> I pass - having failed chemistry hopelessly at school.
neutral  B D Finch: Bicarb + vinegar is very useful for cleaning sink wastes, but I don't think you can make soap from it.

Reference: caustic soda

Reference information:
By the time I had my answer ready DLyons had already posted his, but here it is, with some evidence to back it up:

If this is right then of course "acide" is a misnomer, because caustic soda is a strong base, the very opposite of an acid, but I think it's a popular non-scientific meaning of "acide" meaning simply something that burns.

Two points lead me to this conclusion. First, here's a page on how to make olives from the tree edible:

"Comment tranformer les olives de mon arbre pour les rendres comestibles ?
Il faut les faire tremper dans de l'acide de soude pendant un nuit, un litre de soude pour 10 litres d'eau, rincez trois fois de suite à limite de 12 heures minimum d'espace entre chaque rinçage, ensuite vous mettez les herbes que vous voulez dedans !!"
http://www.explic.com/10375-olives.htm

Traditionally, olives are soaked in caustic soda.

Second, here is a news report on an accident involving a tanker:

"Un camion transportant de l'acide de soude renversé sur la rocade
Ce jeudi 17 juin, vers 6 h 50, un camion transportant de la soude caustique s'est renversé sur la rocade de Rennes, à hauteur de la porte de Normandie, sur la commune de Thorigné-Fouillard."
http://www.rennes.lemensuel.com/actualite/article/2010/06/17...

NOT bicarbonate: no reason why that should be called "acide" and no connection with soap-making that I know of.

I think caustic soda is accepted in "natural" soapmaking. It's pretty well indispensable, really. See the quotation I've just posted in the discussion area.

Asker: Thank you, I'm thinking along the same lines. It's only that I could not find the term explained AND the maker says almost 100% of the products are natural (vegetal)!
