Hey guys, I was wondering if anyone, here, could suggest (and even offer some substantiation, either through literature, for example) via tried-and-true methods for thickening up an alcohol-based liniment, like one finds Purell? When my Lemon Balm has matured this summer (it SHOULD be mature by May sometime, though it seems to be growing very slowly, albeit's in a pot outside during the day, and I pull it inside when evening falls) I was planning on making it into a liniment (as well as a cheesecake, etc.!) for my leg muscles, because I walk and job to stay fit (well, I'm trying, anyway). So, I'd like to produce a liniment that has a body and structure, so that when I pour it into my hands it wont run through my fingers and get on everything, etc. Ya' know what I mean? Sadly, Purell doesn't list what they use to thicken up their wonderful product!
