I just called the 1-800# and never expected to get thru, thinking that it would just be for USA use.
I was told that it's a synthetic spray starch and number one used by quilters!
It was easy for me to talk to him as I told him the stuff is like gold here (price is ^^^) so he had to convince me why it's so great.
The MSDS is on it's way to me.
Not that it will make much of a difference!
