I put it on my guy once and he had no problem with it, but my skin burned horribly from it, so I quit using it then and there. I always use Sore No More, happened that the tack shop was out of it so I bought the Vetrolin since it was all that they had. Ordered some Sore No More online later that night.
My (part-leased) OTTB gelding gets a mix of Bigeloil (I believe that's how its spelled?) and rubbing alcohol sprayed and rubbed into his legs after he works. I've seen how he can stock up without it (he's a little older, had a 3 year race career) and I'd say it does a nice job
The alcohol evaporates quickly and cools the legs. He gets it up to and on his knees and hocks for flat, and to his stifles when we jump.
We also use Sore No More liniment if we can't find the Bigeloil. It works well too
I burned my horse with Bigeloil gel once. It was an older bottle, and apparently in some cases the water in gel liniments can evaporate and leave the gel more concentrated. I stick to using the menthol-based liniments mixed with water as a brace and go for a SNM/alcohol blend for vigorous rub-downs.

What's strange to me, is that it seems to slowly burn...when I first put it on him, he didn't react at all - same with the second time I put it on. Poor thing! I can't imagine how it must've felt to sloooowwwwly start burning his skin
