Claim: Bat guano is used in the manufacture of mascara.
our shampoo causes cancer, our scrubbing sponges contain formaldehyde, and our lipsticks are loaded with lead (and even go so far as to worry about how much lip goo women swallow in their lifetimes). We also fret (needlessly, it turns out) that our mascara contains bat poop.

Upon getting ready for school this morning, my 12 year old daughter informed me that her mascara was made with monkey eyeballs.
Rumors about icky or even dangerous substances lurking in ordinary household and personal products are our way of voicing that sense of disquiet, thus we fret that
Origins: One of the less appetizing aspects of modern life is having to entrust our personal safety and wellbeing to those responsible for churning out household and personal care items. Precious little of the process of bringing these items to market is transparent, and the products that end up in our hands arrive emblazoned with lengthy lists of polysyllabic ingredients that make the task of working out exactly what went into them almost impossible. Ultimately, we have to cross our fingers and hope that the manufacturers have done right by us. But even so, there is always that little nagging sense that all might not be entirely well with many of the items we use on a daily basis.
I was told that all waterproof mascaras have tar.
Bat guano has commercial uses, but not in the cosmetics industry. Instead, highly regarded fertilizer is made from bat droppings because this type of excrement is incredibly rich in nitrogen. (Thanks to its nitrogen richness, bat guano was at one time used in the manufacture of explosives.)
