Thank you for the insight, definitely a lot of variables with candle making that makes it fun but also frustrating. In your opinion, which retailer has the best FO for quality as far as concentration/throw go (goal is strong throw without requiring enormous amount of oil (reasonable to me is 6-8%)? I feel like CandleScience and The Flaming Candle seem like ones I can trust most so far.
I'm also interested in understanding additives and their effect on the wax and scent throw. For example, my understanding with Vybar is that consists of several sized branched poly alpha olefins with numerous structural conformations that decrease intermolecular interaction, with the purpose of inhibiting crystallization seen with natural waxes. Themes appear to be that the more amorphous a wax, the more likely it will not frost, produce sink holes, have bumpy, have increased glass adherence, etc. Along with that, I've read a patent that aims to increase scent throw by decreasing surface tension of the wax and allow for aromas to escape more easily into the atmosphere ("antifoam agent").
Is there any data compilation of different candle additives and their effects on candles with some reference to what is happening on a molecular level? I just want to know what to expect with additives otherwise this blind experimentation is enough to make most people go crazy I feel like.
