Now this is one I find odd. Ok, no heavy make up (you don't want mascara flaking into your product), no perfume and no nail varnish but really? What is the point in banning a bit of concealer or lipstick? I see no point to be honest and I'd rather fight the battles I feel are important and just say "no heavy make up" with specifics on no false eyelashes, perfume, nail varnish etc but then make sure people wash their hands! For a lot of women working in industry "no make up" is a really difficult thing for them to accept and in my opinion without good reason.
I say concentrate on the things that really matter rather than fighting this battle for the sake of it.
I agree. Fight the battles you can definitively show with evidence to be a 'risk' after all that's the whole point. False fingernails - easy to demonstrate the risk - I've actually received some labels from a supplier with a false nail in it! - Lipstick - not so much. It should be all about the risk containment, and a little make up (agree excessive make up can be vetoed) isn't in my experience a high risk item.
