A Certificate of Analysis, or COA, is a document that establishes that a product was analytically tested and meets specifications of safety and quality. Retailers require a COA from suppliers to ensure that the supplier has done their due-diligence to ensure the product remains safe for consumers, and the quality is as expected. To obtain a COA, samples may be sent to AEMTEK for analysis, where we will perform the standard cosmetic testing panel. Results will be issued in the form of a Certificate of Analysis for each individual product. The standard panel includes the most common tests used to determine product safety and quality for cosmetics.
