Explore the most common questions related to slip melting point and dropping point analysis, along with their answers. |
The dropping point and slip melting point are key thermal parameters frequently utilized to assess the quality of raw materials as well as the waxy properties of final cosmetic products. In cosmetics such as lipstick, foundation, and mascara, these measurements provide crucial information about the thermal behaviour and consistency of the products, ensuring that quality always remains consistent.
Slip Melting Point
Also referred to as the open capillary method, this technique allows for the determination of the slip melting point of non-crystalline samples. Video analysis ensures accurate identification of the endpoint, and the ability to conduct two replicates provides reassurance that the sample is consistent.
Dropping Point
Alternatively, the dropping point technique can be utilized instead of the slip melting point. In this method, the sample is placed in a cup made of aluminium or chromium plating, and the temperature at which the first drop of the sample is observed to fall during heating. This detection process also relies on video analysis.
