Tetenal C41 and E6 stabilizer the same

From this site, it looks like Tetenal C41 and E6 stabilizer are the same.

In the US all tetenal and Fuji hunt E6 kits are back ordered, and it can’t be shipped from the EU.

I do have a lot of unicolor C41 stabilizer from a recent batch.

Other E6 kits like Arista, unicolor, Edwal, FPP don’t come with E6 stab.

do you think it’s okay and the same if I just use Unicolor C41 stabilizer with like an Edwal E6 kit?

Stabilizer from all sources, either Tetanal, Fuji, Kodak and other will be probably a similar formula and with the same purpose so I would think if you use it there will be no adverse affects or if it doesn't work, then no damage will be done.

As a suggestion, why not try it out on a slide that you already have and see if it causes any damage.

The problem with stabilizers is that you'll only know if they are effective 10 years down the line. This would in particular be of concern with e6 film as contemporary c41 films don't need a stabilizer for dye stability, only for eg antifungal purposes.
There's a really useful sticky thread on it that many people seem to overlook: https://www.photrio.com/forum/threads/the-definitive-word-i-hope-on-color-stabilzers.89149/
