Read this on Caroline Hirons' blog that is quite interesting :
As a rule - stay clear of 'foaming' on the bottle (there is the odd exception, but they are few and far between) - to get foam you need to use a surfactant - and a surfactant turns your skin alkaline. Alkaline skin is like a petri dish for bacteria. The irony being that so many cleansers pushed on to acne/combination skins are foaming. Naughty, nasty companies should know better.
