Not if they're all getting a key component from the same supplier. Every niche brand and even someone like CVS isn't going to run it's own chemical refineries for each ingredient in the sunscreen. They're going to use a relatively small group of suppliers. It only takes one of them selling to dozens of manufacturers to taint both mainstream and obscure brands.
- devman0 5y agoQA can be a big differentiator between competing companies that share upstream suppliers. It could be that one sunscreen maker is testing for crap/contaminated precursors and another isn't.
- ineedasername 5y agoGood point. The difference between quality products sometimes just comes down to specified mechanical tolerances and purity levels of chemicals/ingredients. Though price usually increases much faster than quality at higher levels. Going from 95% to 97% pure might cost $X, but 97% to 99% will be $X * 5.
