Topicals Testing


ACS is rated in the top 5% in the U.S. for hemp and cannabis testing. Our methods are proven and we guarantee precision. Before testing topicals for potency, we meticulously extract the delicate cannabinoids from the product. Then we determine potency through High-Performance Liquid Chromatography (HPLC) using a UV wavelength detector to identify various forms of cannabinoids. This method provides consistent, reliable results that you can only find with a top-rated lab like ACS. 

In the last two years, we have received 42 badges for excellence from the Emerald Test, a nationwide Inter-Laboratory Comparison test.

Topicals Contaminant Testing:

ACS tests topicals for pesticides and contaminants that could be dangerous through contact with the skin. We know the most common toxins and the maximum levels that are safe for human use. We accurately test all topicals, from skin salves and beauty creams, to balms, oils and patches. Cannabis companies can be sure their products are retail-ready and safe to use. 

Am I required by law to test for all of the above contaminants?

According to the FDA, topicals must be safe for use. That’s why we test topicals for contaminants including residual solvents, pesticides, microbial matter, mycotoxins and heavy metals.

Compliance & Beyond:

Safety & Compliance Testing

At ACS, we test hemp and cannabis topicals according to federal and state guidelines, and to identify potential sources of contamination that can compromise human health. But we don’t stop there.

Beyond Compliance

At ACS Laboratory, we tailor our testing approach to the particular product on hand. In addition to cannabinoid potency and safety testing, we also recommend the following tests for topicals:

Terpenes are aromatic organic compounds that work with cannabinoids to produce the overall therapeutic effect. When brands know what terpenes their product contains along with the corresponding concentration levels, they can educate consumers on the product’s unique benefits and aroma. 

Flavonoids are responsible for bright, non-green pigments in cannabis that also synergistically produce an array of therapeutic benefits. ACS is one of the only laboratories capable of testing these compounds, giving brands a key advantage in marketing their products.

Shelf life & stability determines the ideal number of days the product remains stable based on recommended storage conditions. While shelf life testing is not legally required, customers look at product labels to determine best usage instructions. This includes how long their products can maintain optimal potency before degrading.

ACS Advanced Testing Services:

ACS Laboratory is a leading provider of cannabis testing, panels and methodologies. ACS customers receive a print and digital Certificate of Analysis (COA) containing a photo of the product and a QR code for every product tested, as proof that the results are final and accurate.
