I've read on this forum several times that adding borax to soap will nuetralize some of the lye. I did some experiments testing nuetralizing lye and borax does not make it easier. Borax is alkili itself and if anything could shift PH further alkili from nuetral, though not by much.
Borax, though weak, is still alkili enough to change phenolpthalein. No amout added to lye will cause phenolpthalein to "turn off".
So it is my conclusion that adding it to your soaps will not require you to add more lye. Furthermore, it's sodium content will also add hardness to your soap.
