This is a private label and they have had two other suppliers make these for them. They have the 80/20 advertised in their brochure. We got them to switch to 100% soy because the C-1 would not adhere,but we are having issues with the 100% soy adhering to the jar now. Am about ready to pull my hair out. Pour one weekend and they come out fine, next weekend adhesion is hit or miss. Pouring @ 115-120 with room temp of 75 and humidity about 50%. Have any of you noticed if humidity makes a difference on how your candles come out? We are not having any problems with the tops, just the adhesion around the wall of the jar.
