This explanation sounds interesting.Another brain storm. I know, I have nothing for months and then I lay it all down in one morning. That's me.
"Google" does not know everything. You won't find anything regarding the aromaticity of complexes containing oxazine rings.
And you won't find the right answer as to why softened water feels slippery/slimy as if the soap is not washing off completely and/or it takes a lot of extra time to rinse the soap off. I have softened well water. I noticed some things.
They say the slippery feeling is just your natural body oils you're feeling. Well I disagree. Yes, if your hands are oily to start with then it will take much longer for the "squeaky clean" feeling to occur, or, conversely, if you have been making hamburger with vinegar on your hands then you will get the squeaky clean feeling right off the bat real quickly.
Here's the thing. Say you wash your hands and it takes a long time to get to the squeaky clean feeling. OK, the "natural oils" should be all gone right? So that if you go right back and wash them again, they should reach the squeaky state much much sooner, but they don't. It's the same thing over again.
Also, when washing palms together it's much different than washing other body parts; palms take longer to get squeaky.
Personally, I think it is a surface phenomenon and I think it does involve soap and not body oils. I think that it involves a very very very thin layer of soap, but soap nontheless.
If you keep one hand away from the dishsoap, using the other to wash with, you'll see that once you rinse the soap off the plate the kept hand will be squeaky against the plate and the other will not (after rinsing the hand equally as much as the plate).
So, obviously the soap is rinsing off the plate in short order but not off the hands. It has to be the soap.
I was told by a conscious force in my dreams that the world would end if that problem was not solved immediately. Don't thank me, it was my duty to save the world, how could I live with myself if I had ignored the voice?

I always thought Soft Water caused *better* rinsing. Apparently not so in the case of soap.
