A few months ago I started using Ecover but am finding it very very drying, to the point of cracked bleeding knuckles at times! I've switched from Ecover washing up liquid to supermarket's own brand eco, which seems to have helped a bit, but Ecover soap isn't cheap so I'd prefer to use something a bit nicer once I know what that something is!
I only use bars of soap now (usually from the Simply Soaps range at Love Your Skin). It's the only thing that doesn't leave me with cracked bleeding hands.
We use Carex Anti-bac liquid soap. DH is a bit on the paranoid side about handwashing and so insists on this stuff. It's not too bad on the hands, but I am a bit anal about moisturising my hands on a nightly basis.
I know what you mean about ecover, I only use it for washing Jaden's hands (partly because its so expensive!) and he doesn't have any problems with dryness but I have quite bad excema so usually just use a supermarket own brand with moisturisers. I find lavender anti bac's take all the skin off my palms though!!
