I'm a Irish man getting lots of sun working on the roads

I am wondering if i should be worried about the chemical ingredients in my work supplied sunblock specifically. Homosalate, Octocrylrne, Octisalate, Oxybenzone and Avobenzone. I've read most of these ingredients are worrisome to humans and would like to know if i should continue applying or just cover up the best i can and face the sun raw. Thank you
