If mascara was made of Bat Poop, can you imagine the lawsuits? The PETA Magazine cover spread? The Dateline special narrated by Keith Morrison? The endless reel of jokes on Saturday Night Live? The smarmy, smirky commentary on MSNBC?
So then why do people even ask the question, “Is Mascara Made of Bat Poop?” The confusion arises because bat poop is also known as “guano,” and guano is actually used in a lot of products. Thankfully, one of those products is not mascara.
It is actually guanine, not guano, that is used as a color additive for cosmetics. Guanine is authorized by the FDA, and it must be extracted from fish scales, not bat guano. The guanine in mascara does not come from bat guano (poop). However, it does still come from an animal, so if your concern is that an animal product is being used in your makeup, then you need to hunt for animal-friendly products.
Cosmetic companies use synthetic ingredients in their mascaras. If you want to be completely sure, read the label to see the ingredients. If there are any terms you don’t know, Google them to put your mind at ease. No company is sneaking bat guano into your eye makeup—it’s not happening.
Trust me, if this were true, you would know about it, really know about it. The idea that mascara is made of bat guano is nothing more than a myth, no matter what anyone, especially a cosmetics sales rep trying to diss another company, tells you. There are some companies, especially a certain multi-level-marketing company, that tells its sales reps to inform customers that their competition uses bat guano in its cosmetics. This is not true, it is merely propaganda.
Again, when in doubt, do your own research. Check the labels on your cosmetics, or call the companies directly.
