A/B extraction of lactone

[18294]

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 NaOH  to turn the GBL into NaGHB salt, then boil off the rest of the stuff. Does anyone have any comments?

[hypo]

ethyl acetate and butyl acetate will become ethanol resp. butanol and NaOAc.
chemistry 101.

Where do I get info on citrus dilcis and D&C 17 so it can be pulled off of butyrolactone.
