Don’t add lye or caustic soda
.What exactly are you making? -

A body lotion @Benz3ne and the ph was too acidic and to reduce it, I divided the cream into two, added caustic soda in one and lye in the other and ended up foaming and overflowing out

I am scared to imagine what pH it has… Post the formula.
-
caustic soda IS lye.
-
If it foams, it’s likely sodium carbonate, a no-go these days .You don’t ‘reduce’ too acidic pH, you neutralise it. Reducing pH usually means lowering it and that means making it even more acidic.Sodium hydroxide, TEA or free base arginine should work without foam.

I’m curious as to why the pH was so low also. If adding sodium hydroxide (as a solution rather than pellets, right?) caused foaming/overflowing then something is reacting to create gas… doesn’t sound right to me.
Sodium hydroxide = lye = caustic soda, so we’ll need clarification on this point as to what exactly you’ve added, or differed between the two trials you’ve conducted.
Try TEA as @Pharma has suggested above.
Read up on pH as well, it’ll give you a good idea of which direction to go and how to do that. Also be worth looking into soap making, as if you’ve free oils in your mixture (body lotion) then you have a potential to saponify them by adding caustic soda/lye/sodium hydroxide/potassium hydroxide/potash creating soap.
