I ordered a pint of this stuff to try, seems pretty cool but a little bit stiffer than what I'm used to. My question is if you are adding softener to this "phthalate free" plastic, doesn't that eliminate the purpose of it being P-free? I saw that DOIT has P-free softener, but I've still got gallons of other softener. Can I assume that my existing stuff isn't P-free?
Thanks
