SCENTED ANTIPERSPIRANT EMULSIONS Table III compares the responses generated by the tube method at BM with those obtained by direct sniffing. The Table and Figures 5 to 8 indicated that all laboratories found some odor reduction with the placebo. This reduction was much more pro- nounced at all times with direct sniffing in two of the contract laboratories.

BM and Laboratory #3 scored odor similarly at 3 and 6 hours but the contract labo- ratory again found pre-application odor levels at 24 hours (Figure 7).
