Cosmetic Testing Labs - how to know if they are legit?
Hi. We need to test Bath Salts for a Microbiological limits and Toxic Element/Heavy metals. We got quotes from several Labs and the coblarlabs.com/faq/ provided the best price quote. When I wanted to find out more about this Lab - there is no other information online besides their own website. The question: what one should look for when hire the Lab (certification, etc)? what questions should I ask them? how do i know if they are legit? Has anyone heard/worked with that particular Lab? Thank you very much in advance.
