no they dont use animal products in chocolates.. It was a really big deal a while back cos the Vegetarian Society (or summat like that) announced that Masterfoods was now gonna start using animal material because it was cheaper, so the chocolates were no longer suitable for vegetarians. I tell you when I found out I was sooo upset, I love maltesars and galaxy!!
But alhamdulillah, Masterfoods changed their minds because they received an enormous amount of complaints and said something about valuing customers opinions so they're still halal yay!!!
