I know it's a stupid question, but I'm a bit desperate in terms of getting soil right now...
Can I use eyeshadow in soil or compost? When I dropped it, I noticed it behaved a lot like (very powdery) sand. Y'know?

nicodiangel_no,

The question would have to be, what is the eye shadow made of? My knee jerk response is NO. But it could be some type of organic eye shadow I suppose than would be harmless. But unless you had a unusually large amount of it, I would not see it doing any good at best.

I don't see it doing any harm or good. Eyeshadows are mostly made up of talc, or clay, with an added binder and some pigment. I would think if it were safe to apply directly to the skin it would do little if any harm in compost. Even if there was something in it that was borderline harmful, the volume would be so little that it would be rendered harmless. Of course I'm not a scientist or doctor so I could be wrong, but I doubt it.

Thanks, Larry! I read the ingredients ((sadly, none of them were even vaguely recognizable)) and decided to just clean it up. It stuck to my fingers quite a bit, and I had an awful time getting it off- even if they were harmless minerals, it would be a waste of water to use it anyway.
