As a result of a guilty conscience about my wastebasket full of paint rags and their possible environmental impact, I started reading labels, with the same results I get when reading the fat content of a bag of anything from the candy machine at work. I cleaned up my act.
I quit using W&N Titanium White and started using Weber's Permalba because it had a non-toxic label, but found it had the consistency of Marshmellow Fluff. It also came in a puffy plastic tube, which may be why I found disturbing bits of dried paint when squeezing out the last inch of the tube. I just found a better alternative in Gamblin Titanium White. It has the same consistency as W&N, a sturdy metal tube and a health label I can live with.
