Benzyl benzoate

I'm not sure, but there are plenty of places to get it that ais USP grade and in sealed viles. It's cheap, so no need to mess around.
 
Isnt USP grade a standard for US products? If its manufactured outside of the US or for use in another country would the same standards for strength amd purity apply?
 
Do you know how good BB is for treatment in lice in other countries? Just throwing that out there because it is the main ingredient in a shampoo issued by social medicine systems in Latin America.
