2021 Sep 24: Our experts have identified both of the substances in this sample and our lab has confirmed these identifications with certified reference standards from Sigma-Millipore-Aldrich / Cerilliant.
Unidentified #1 was a clear match for Octocrylene (CAS 6197-30-4).
Unidentified #2 was a slightly less clear match to Bis(2-ethylhexyl) isophthalate. We received the standard for this and ran it several times. It matches, nearly perfectly, the unidentified#2. On a technical note, this chemical GCs so efficiently and clearly changes in the GC column that we ran it through at several dilutions, trying to match the amount in the original sample, and saw that the mass ion m/z heights moved around a little based on the exact run parameters. We now consider this a resolved identification.
DrugsData has no explanation for the combination of these two chemicals in this 'Mystery' sample. They are ingredients in sunscreens and plasticizers. No psychoactive drugs detected.
Send in a sample for testing
DrugsData tests all psychoactive drugs including ecstasy tablets, powders, research chemicals, novel pschoactive substances, and other drugs through our DEA-licensed laboratory. Ecstasy/Molly tablets cost $100. Recreational drug powder/crystal/blotter costs $100. Pharmaceuticals, supplements and all others cost $150 per analysis.
Should the public have access to independent analysis of the products they consume?
The vast majority of analyses of over-the-counter, prescription, and recreational drugs are performed in secret with no independent oversite or review. No other historical record, free from politically-controlled agencies, is currently available in North America nor most other parts of the world.
DrugsData, a project of Erowid Center, needs the support of professionals, students, parents, individuals with means, and small foundations for a total yearly budget of around $120,000 USD. Erowid Center's general budget and the co-pays we require fund most of this cost.
