I just purchased Christmas Pine FO from Mikes fragrances and I'm really shocked bc it smells great (almost exactly like BB Christmas forest, and to me a real pine tree) and I soaped with it at 0.8 oz ppo and it was extremely strong.
I was able to pipe it into little Christmas tree shapes. I don't think there was much acceleration. I didn't like how they ended up looking so I re-batched them and even after the re batch they are so strong. If I put another soap next to it, it starts picking up the pine smell. For me, that's a winning fragrance. Next time I will do 0.5 oz ppo.
