I received a package of menthol crystals today and I want to mentholate some witch hazel, it's a full bottle and I'm shooting for something near Alcolado/Osage Rub in chilliness. I understand I should add a little, try it out and add more until I reach my desired level but, I want to know is this stuff potent where a little goes a long way or should I just add a teaspoon to start out?
When I add the crystals to anything I typically end up with more than a teaspoon for a bottle. That being said, I would definitely recommend starting small and add a little at a time until it feels just right to you. You can always add more.
I did this the other day to some citrus WH and love it. I used a Micky D desert spoon amount of menthol crystals to 100ml of the WH. It took a few days for all the crystals to be azorbed and turned the WH white like milk.
