Hydrex is 4% chlorhexidine gluconate and so is Hibiscrub. They both also contain emollients, although I think they are different ones. I dilute either to about 1 in 8 with water before use on an animal.
The hydrex i have is 2.5% and the hibiscrub is 4% so maybe theres different versions of it
Has anyone tried Videne 7.5% surgical scrub if so how did you get on?
