Can I mix my npa with grape seed

I want to add an oil to my New Pheromone Additive but I am concerned about the fact that it is in alcohol. Will this just make a thinner oil or will it somehow not blend correctly. I use grapeseed oil for
My beard and skin and it is nice and thin I just don't want to ruin my bottle of New Pheromone Additive.

I was gonna do a 50/50 mix at first. Should I even attempt this or will this lead to inevitable failure.
