That got me thinking: Why is something "worth gold" sold for so little when there are many expensive, high-end sunscreens selling well? Surely there is something wrong with mine. I began to investigate the ingredients: The particular bottle I bought was paraben-free (though not all Coppertone sunscreens are).
I decided to dwell deeper and look up all of the ingredients on ewg.org. If you are unfamiliar with EWG's Skin Deep, it is a cosmetics database that lists the health risks, toxicity, and safety of many common cosmetics ingredients.
EWG's Hazard Score Key
Looking through the database, I noticed that my particular sunscreen lotion is listed with an overall rating of 4, which would make it fall under moderate hazard. (To put things in perspective, Aussie Shampoo also has a rating of 4.) The most hazard of ingredients listed is oxybenzone, which scores a 7 on the EWG hazard scale. Benzyl alcohol and triethanolamine respectively scored 6 and 5, which the rest of the ingredients scoring from 0-4.
As it seems, there is nothing especially wrong with my lotion. The most dangerous ingredient turns out to be the sunscreen itself. Accumulation of what seems like innate chemicals can lead to serious health issues - but that is a risk we take to avoid sun damage, aging and cancer.
Ingredients: Homosalate, Oxybenzone, Octisalate, Octocrylene, Avobenzone, Water, Styrene Acrylates Copolymer, Propylene Glycol, Neopentyl Glycol Diheptanoate, Bis Stearyl Ethylenediamine, Stearyl Hydrogenated Dimer Dilionleate Copolymer, Benzyl Alcohol, Acrylates/C10 30 Alkyl Acrylate, Crosspolymer, Oleth 3, Tocopherol (Natural Vitamin E), Triethanolamine, Chlorphenesin, Disodium EDTA
In the end, I am still a fan of my Coppertone SPF 50 Oil-Free Sunscreen Lotion. It isn't obviously more toxic than the food I eat or lifestyle I live. Looking through the cosmetics database though, there seems to be a lot of sunscreen lotions that are less hazardous because they contain physical sunscreen such as titanium dioxide instead of chemical sunscreens. (Read about physical vs. chemical sunscreens.) I will try some of them after I am through with my Coppertone.
I hate looking up ingredients and studying their toxicity. It is troublesome and possibly unnecessary as many ingredients can't be avoided entirely. But it is scary that there are too many toxins to avoid. Most chemicals pose some threat or another - and that is only based on small studies of some ingredients. Can you imagine the dangers brewing behind the chemicals we have not had time or resources to thoroughly research?
