THE SUN NEVER SETS
The sun never sets oirthe work of the true researcher. From the inquisitiveness of a youngster with his first chemistry set, through to the trained, calculating research chemist, the mind that searches into the unknown and produces new things works around the clock. Dow Chemical Research has produced another new product that should serve industry well. Dipropylene Glycol—a clear, almost colorless, somewhat viscous liquid, is now available in commercial quantities up to carload lots. It may be used as a solvent, a chemical intermediate, a humectant or a plasticizer. In fact its many and varied uses have yet to be fully explored. Perhaps this may suggest your investigation—write to Dow and freely consult with their technicians. Your confidence will be' respected.
