I'm going to go back and read BUT I have had great success with soy waxes. I think I started about 2003 or so. I used 100% soy from TN Celestial, Bluegrass, KY, Golden Foods 415. I don't particularly care for GF 464. I didn't like the soywax from Candlewic. I could never get the wicking solved. Then I tried the soy/cottonseed soy wax from KY. Stuck with that for some years. Then I moved to Enchanted Lites because I could pour hot and the scent throw was out of this world. I preferred the regular over their millenium blend. I used their regular soy until they went out of business.
I have never had a problem with scent throw (cold nor hot). I test, test, test, test fragrances in my own wax blends. I keep other wax reviewers results in the back of my head but my own testing supersedes all other testing. My scent blend is usually 8% max. If a fragrance oil doesn't perform at that percentage, it's not worth my money. I test my scents at 3 day cures and 7 day cures. I'm not waiting a 14 day cure for my candles. People might not agree with my fragrance evaluations timeline but it has worked for me.
My preference is straight cotton wicks: 44c, 51c, 60c, 62c (depending on the jar). I've tried other types of wicks and nothing has compared to straight cotton for ME.
I made my own parasoy blend with KY soy/cottonseed and 4627 (comfort blend). I didn't stick with it because I had to test every fragrance oil again and that was too time consuming for me when I already had a tried and true that worked. The fragrances I did test were fantastic as well. I also tested some fragrances that didn't work great in my 100% soy but worked much better in the parasoy blend.
My daughter gave me a great compliment the other day. She's away in another state going to school. She said mom, I need you to send me some candles. She said I bought some from the store but they don't compare to your candles. She said I can still smell your candle scent in my apartment even if I haven't burned for 2 days. She said with these new candles, I still smell the boiled eggs I made the other day. LOL
If it hasn't been said already, I would buy small increments of different waxes and test that way.
