Which part caused the inflamation? The soap you used or the stuff in the rinse? I kinda make my own detergent – I use a 1/2 borax, 1/2 washing soda mix, I fill my detergent scoop about 1/2 full, then add 1/4th reg powdered detergent.
I don’t fill the scoop entirely. Then I use downy for the rinse. That is quite a concoction for the softener. Why did you use baking soda in it?
