Sounds like a Patentable formula...
I remember reading about an “environmentally friendly” paint that was milk based. Envros were getting it from somewhere and painting interior walls with it. It didn’t exactly age well, lets be frank it rotted and smelled like spoiled rotting milk!
So latex here for the ice cream!
maybe lead-based so one gets their necessary vitamins, minerals, etc
and yes patentable!
Its amazing what I have seen patented!
