Correct and accurate slip melting point and dropping point measurements depend on reliable instruments. Learn how to achieve compliant lip balm measurements according to AOCS standards. |
Importance of the Slip Melting Point and Dropping Point of Lip Balm
Lip balm is a very commonly used cosmetic product for the moisturization and hydration of lips. The main ingredients used in lip balm are different types of wax including paraffin and natural waxes like beeswax or carnauba wax. In addition to flavors, dyes and fragrances are added. Slip Melting Point and Dropping Point are reliable and easy accessible quality control parameters to characterize such complex mixtures.
Slip Melting Point Measurement Principle
The slip melting point is also known as Open Tube or Open Capillary Melting Point. In a glass capillary tube open at both ends, 10 mm of a lip balm sample is introduced and then placed into an outer capillary filled with water. The latter is acting as a temperature-controlled water bath. The slip melting point is the temperature at which the substance begins to rise in the capillary due to the effect of the increasing temperature and buoyancy.
In this application note, you will learn about the sample preparation steps and slip melting point measurement according to the AOCS Cc 3-25 standard using the METTLER TOLEDO’s Melting Point Excellence instruments MP55 and MP80.
Dropping Point Measurement Principle
The dropping point measurement principle is based on the detection of the first droplet of molten substance that escapes from a standardized cup under a controlled temperature program. In this application note, you will learn about the sample preparation steps and dropping point measurement according to the AOCS Cc 18-80 standard using METTLER TOLEDO’s Dropping Point Excellence instrument.
