I have PA's Sandalwood accord. It smells toxic, just like the strong vinyl smell when you unwrap a new shower curtain. In fairness, that is my impression of it smelled alone. Maybe it would be better used in small doses in a blend. I've had success using Ebanol and Javanol, along with a little New Caladonia sandalwood oil.
It's too bad that you say their rose key accord isn't so good because I have some on the way.
