Slip melting point

Slip melting point

The Slip melting point (SMP) or "slip point" is one conventional definition of the melting point of a waxy solid. It is determined by casting a 10 mm column of the solid in a glass tube with an internal diameter of about 1 mm and a length of about 80 mm, and thenimmersing it in a temperature-controlled water bath. The slip point isthe temperature at which the column of the solid begins to rise in the tubedue to buoyancy, and because the outside surface of the solid is molten. [European Pharmacopoeia method 2.2.14]

This is a popular method for fats and waxes, because they tend to be mixtures of compounds with a range of molecular masses, without well-defined melting points. [ [http://www.americanpalmoil.com/glossary.html#28 America Palm Oil Council glossary] ]
