@Group 5 minus 1 I understand you feel squeamish but the reality is you have no way of knowing if any ingredient in any item you use was not sourced from off shore facilities. Assembled in USA does not necessarily mean some of the ingredients were not imported from China, Taiwan, Vietnam, etc. Brand is not always indicative of better or safer. Even with a waving Stars and Stripes on the label.
My dad, before he retired, worked at Lever Brothers which is now Unilever. Back then, they were pretty much a soap company only. He would bring home cases of brand name brand stuff, like Whisk laundry soap, Dove bar soap, Lifebouy bar soap, etc. Sometimes, he would bring home an off brand...same exact bottle or package but with different labeling. My mom would turn her nose up and say why did you bring that cheap stuff. He would tell her that stuff in the off brand box or bottle is actually the name brand stuff packaged in the vendors packaging. He would watch the machines fill up the name brand bottles and then would come the row of off brand. Exact same stuff. When she realized he was right, that ended that! He would ask her do actually think Two Guys brand (a back then local dept store) or Tops Dept store brand has a soap manufacturer? Nope...they use already established companies and slap their label on it.
Now I do realize that's not all off brand products but again, you have no way of knowing.
