SWIM knows of an OTC product with the following ingredients:
Butyl Acetate, Ethyl Acetate, Isopropyl Alcohol, Butyrolactone, Dibutyl Adipate, Citrus Dulcis, Cl 26100 (D&C #17).
He thinks it would be possible to simply add NaOHÂ to turn the GBL into NaGHB salt, then boil off the rest of the stuff. Does anyone have any comments?
