Used in 444 Soy with good results on hot throw, but not the strongest I've ever seen. It's definitely a good general "baking cookies" scent for your candle line that will be popular over the holidays for sure. The cinnamon is not too prevalent so it might be a good companion to the stronger cinnamon scents (for people who don't like strong cinnamon) while still having that "Christmas cookie" feel.
I got 4oz bottles of Cinnamon Buns, Gingerbread, Hansel & Gretel's House, and Creme Brule, and I have to say they are all so similar that I can hardly tell the difference between them in a finished candle, with Creme Brule being the most different. If I were trying to come up with a selection of food scents for a candle line, I might only pick one of these four to include. They all have slightly different notes, but after a while you realize they all have a very similar overall tone. I would suggest trying smaller bottles of these to see which has the undertone you prefer, or try mixing them with other scents that compliment their specific undertones to bring out a wider variety of custom scents.
