I've been having some problems with a couple of my scents changing colors after they are packaged in shrink wrap. I'm only having this problem with my votive (IGI 1284) and pillar (IGI 1239) waxes. I add 1 teaspoon of vybar and 3 tablespoons of stearic per pound of wax. I also add 1/2 teaspoon of UV Inhibitor (from Peak's) per pound of wax. I use between 6% and 9% fo. Do I need to add more vybar or does anyone know if it has something to do with the shrinkwrapping? This happens mainly with my Lilac, Lily of the Valley, Green Aloe and Clover and my Blueberry Muffin scents. Thanks! Tracey
