ASTM D937 Cone Penetration of Petrolatum
When formulators of lubricants, cosmetics and many other products need a low toxicity base ingredient that melts around body temperature, they often choose petrolatum. The consistency of the chosen petrolatum will help determine the firmness of the final formulation. This test measures petrolatum consistency.
The petrolatum sample is melted and slowly cooled to 25ºC. The penetration value is determined by allowing a standard cone to fall into the sample as per the method. The depth to which the cone sinks is reported in tenths of a millimeter.
