What testing is necessary for a hair gel formula before releasing to the public?
Hello. I understand that a USP 51 test and a microbiology test is necessary but are there any other test needed? Also any testing facilities in Tennessee? Thanks!

One USP 51 by itself is not enough - you should ensure the preservative system is stable.
“Safety” by whatever tests or rational must be established. It can not be presumed, one must have an affirmative justification.
Per 21 CFR
A cosmetic is considered misbranded if its safety has not adequately been substantiated, and it does not bear the following conspicuous statement on the PDP:Warning - The safety of this product has not been determined.
