I was using 8 % in ez soy. The other gragrances that I had a very weak scent throw was cinn. roll with van. cream frosting, van. buttercream was ok in a small room. Js told me that these all had excellent scent throws. The biggest problem that I had with just scent was that I wanted to try a soy/para blend so I tried there blend. I made a pine forest candle and the whole jar started on fire. 4 inch diameter flame. Js told me that it probably was my cd wicks burning hot. I have probably made about 15000 candles before including parafin and soy and never had a problem like this.
