2012 Collaborative Study on Humectants

STS Technical Report

February 2015

A collaborative study was conducted in 2012 to evaluate the suitability of the CORESTA Recommended Methods (CRMs) Nos. 60 and 61 for the determination of 1,2-propylene glycol and glycerol in smokeless tobacco products. The study results demonstrated that the methods are fit for use and that the scopes of both CRMs should be updated to include smokeless tobacco products.
