Transdermal Caffein Patch COA Testing - Amazon Requirements

Project Description

MULTIPLE TESTING

We're looking for an ISO/IEC 17025 accredited laboratory for claim verification and composition analysis of a transdermal caffeine patch product we wish to sell under Amazon’s Health & Personal Care category. The patch is marketed as a general wellness product and not a dietary supplement or drug. 

1. We will need to verify that caffeine and potential markers of green tea extract (i.e., EGCG or total polyphenols) exist in this patch. We would need this confirmed via HPLC or LC-MS; We would need the amounts of these ingredients verified as well.
2. We would need a safety panel conducted on the patch. Specifically, test for heavy metals such as lead, arsenic, cadmium, and mercury using ICP-MS or an equivalent sensitive method. Ensure the levels of these heavy metals are below the acceptable limit per Amazon standards.
3. We need to perform microbial testing per USP or validated protocols, including but not limited to aerobic plate, yeast, and mold counts, as well as, verification that there is no pathogenic bacteria (e.g., Escherichia coli and Salmonella).
4. We need to confirm if any solvents & pesticides exist. Specifically, conduct a residual solvent screen for common solvents (e.g., GC analysis) and a pesticide residue screen (multi-residue scan).
   
5. Testing of the Henkel Gel. Specifically, a statement whether the lab can run a general toxicology or skin contact safety screen on the gel layer testing for things like skin irritation potential.

Please let me know if this could be done with the patch or separately – either way works.

Please confirm you are an. We would need a certificate of analysis for all of this as well. Additionally, please provide the results in a PDF format with a signature and the testing methods listed.
