It\u2019s well known that many widely used cosmetics throughout history turn out to contain harmful chemicals and sketchy ingredients. Queen Elizabeth famously wore a heavy foundation made of lead<\/a> as was typical of facial cosmetics at that time. Given the reputation of cosmetics to contain such questionable ingredients, it\u2019s normal to question exactly what\u2019s in makeup and other toiletries.<\/p>\n

One commonly held belief is that mascara is made from bat poop. But is it true that mascara is made from bat poop? Thankfully, no, it is not true that mascara is made from bat poop. However, there is a perfectly reasonable explanation for why people believe mascara is made from bat poop. Furthermore, exactly what\u2019s in mascara may still have many questioning using this particular cosmetic.<\/p>\n

Is mascara made from bat poop?<\/h2>\n

No, mascara is not made from bat poop! So what is mascara made from exactly? According to WebMd<\/a> \u201cmascara’s ingredients typically include a carbon black or iron oxide pigment to darken lashes; a polymer to form a film that coats lashes; a preservative; and thickening waxes or oils such as lanolin, mineral oil, paraffin, petrolatum, castor oil, carnauba wax, and candelilla wax.\u201d<\/p>\n

Consumers should still be wary and \u201cbe on the lookout for thimerosal, a preservative that can cause conjunctivitis and eyelid dermatitis (a rash). Thimerosal is still used in some mascaras.\u201d So while people can use mascara without worrying about any bat poop in their eyes but perhaps remain skeptical of what they use on their faces.<\/p>\n

Why do people think mascara is made from bat poop?<\/h2>\n

If it\u2019s not true that mascara is made from bat poop, how would such a rumor develop and take hold? The reputable fact-checking site Snopes.com<\/a> explains how this misconception originates due to\u00a0 \u201ca similarity between two words that causes them to be confused for one another: guano and guanine. Mascara contains the crystalline form of guanine, a word that derives from the Spanish word guano, meaning \u2018dung.\u2019…. The crystalline guanine used in beauty products doesn\u2019t derive from excrement, though, either from bats or from any other critter.\u201d<\/p>\n

\u201cYet there is a bit of a \u201cyuck!\u201d factor to that ingredient, as guanine is manufactured from fish scales.\u201d That means mascara is technically not a vegan or vegetarian product as fish scales are an animal product.<\/p>\n

It\u2019s also worth noting that \u201cguanine is used extensively in the cosmetics industry, where it functions as a colorant and as an opacifying (shimmering or light diffusing) agent. It\u2019s found in bath products, cleansing products, fragrances, hair conditioners, lipsticks, nail products, shampoos and skin care products.\u201d<\/p>\n

Nor is guanine the only less than appetizing\u00a0 yet FDA approved ingredient frequently found in cosmetics<\/a>. Lipsticks often contain crushed insects as a coloring agent unbeknownst to most consumers. Vegan lipsticks are specially formulated to use synthetic colorants instead.<\/p>\n

Meanwhile, some strange ingredients are advertised as an innovative selling point of a product. Many people now buy moisturizers and face masks containing snail ooze and bull semen \u2013 but not mascara that is made from bat poop!<\/p>\n","protected":false},"excerpt":{"rendered":"
