Sometimes you might notice your coffee beans become oily. Oily coffee bean doesn’t definitely mean whether good or bad. It is just a chemical reaction within. After roasting coffee beans, the beans would crack up, emission carbon dioxide #CO2 and do some oxidized reaction. As a result, the oil of coffee bean comes onto the surface.
However, coffee bean oil is not just some sort of ordinary oil. It can be #sunscreen!
In 1988, a mega French cosmetic company, L'Oréal, (yes, that L'Oréal) had applied the patent about how to make sunscreen by coffee in the U.S.* (off patent now)
They discovered coffee bean oil extracted from coffee ground could filter the sunlight selectively in the wavelength range from 280 to 320 nm, a.k.a. #UVB. Therefore, putting it on the skin could avoid tanning and burning while sunbathing. Additionally, it is natural, not irritating and hard to be washed away by sea and sweat. The ingredient is also merely coffee ground!
Consequently, they made a big fortune…
The story is not finished yet. Seeker’s gonna do seek. The scientists would not stop here and never be satisfied!
Brazilians who love suntan and bikini will not allow French doing all the work alone. In 2011, a bunch of Brazilian scientists from different fields, like biology, botany and etc., took 13 different coffee species and experimented their Sun Protection Factor, #SPF.*
In conclusion, #Arabica coffee, which is the most popular coffee in the world (about 70%) has SPF1.5. the highest SPF is about 2.59 by C. eugenioides from east Africa, like Congo, and the lowest SPF is about 0.35 by #Canephora, which is the second popular coffee in the world (30%).
Hence, next time you spill some coffee on your face or shirt accidentally, just keep cool and tell your friends:” no worries, I just need some #SPF1point5 sunscreen on my face/shirt.”
