Is there soap inside this juice?!

[Triple7]

I have a "Blue Hawaiian" brand Polynesian Punch flavored juice and right off the bat it taste funky. like soap. And the color of the juice is clear but with a purplish-shine/tint to it just like how dish soap is.

I usually keep my juice in a certain bottle and the last juice i had in it was the Polynesian Punch.

As i was washing out the bottle to fill a new juice, soap bubbles started to form inside (i dont use soap to rinse the bottle only warm water)
the bubbles were very clustered and small and had a mutlicolored tint to it, just like dish soap.

Can anyone elaborate on what this is? I noticed the juice gave me a weird head feeling as well. not pain or anything but it was just strange..

Also please dont put emphasis on the soap flavor. The soap bubbles is what REALLY made me confused

I would imagine the pg and vg could foam like that. I have gotten a few liquids that have that soap/perfume smell and taste. They say steeping and airing will get rid of it.
