Fresh Cut Roses from Nature's Garden is another rose fragrance to consider. It's a light, true "tea rose" scent -- it doesn't smell sour or artificial like "old lady" perfume.
I use it at 6% based on weight of oils. It doesn't discolor the soap. It has average scent retention. Like many floral fragrances, it causes light to moderate acceleration.
When using this FO, I soap on the cooler side -- maybe 90-100 F / 30-35 C -- and I add this fragrance as late in the soap making process as possible. I've had enough time to do a hanger swirl if I move right along, but I don't think the FO would allow me to do a more time-consuming pattern.
Whether it's the best rose fragrance or not is up to your nose -- everyone's different!
