This will (hopefully) be a quick question, I've tried looking through the forums and searching online but I can't find this answer anywhere. I love the B&M Terror aftershave, it's one of my favorites, and that's partly in due to the synthetic menthol they add into it. It's much longer lasting than any other mentholated product I've used, so I'm wanting to harness that power for other products. Firstly though, I need to figure out what it actually is. I don't understand much about the ingredients label to identify which type of menthol is used, and there seem to be many types out there so I don't want to guess. Sooo, does anyone out there know already what ingredient they're using? And also, I know you can buy normal menthol crystals and other types of additives online, so I'm also wanting to know if there's anywhere I can purchase this synthetic menthol so I can add it to other aftershaves. Thank you in advance for any help!
