Director- Sorry to hear about your missing stocks. Per your inquiry I forwarded it on to the VP of Scientific & Technical Affairs for the Consumer Specialty Products Association, Inc. His reply is below:
“Gum of mastic is sticky resin, not volatile. Methyl salicylate is oil of wintergreen—strong smell, but no high, toxic in large amounts by ingestion by not (as far as I know) by inhalation. SDA is specially denatured ethanol, same alcohol as vodka but with bitterants no it can’t be ingested. So I’m not seeing any abuse potential.”
I hope this helps initially. As I am not familiar with the product, so if you have any further questions you may want to contact the manufacturer directly. Please note, I have also emailed this information to you.
