ASTM D127 drop melting point test is a standardized method for determining the drop melting point of petroleum wax, including petrolatum. The drop melting point is the temperature at which the wax becomes fluid enough to drop from the thermometer used in the test under specific conditions. This test is particularly used for petrolatums and other microcrystalline waxes, which are high viscosity petroleum waxes.

Here's a summary of the test procedure:

  1. Test Method A: Involves using a mercury-in-glass thermometer. The wax sample is applied to the bulb of the thermometer, and the thermometer is then heated in a water bath. The temperature at which the first drop of wax falls is recorded. This method requires caution due to the use of mercury, which is recognized as a hazardous substance.

  2. Test Method B: This is an alternative method that uses an electronic instrument to detect the drop and measure the temperature with a platinum thermometer, eliminating the use of mercury for safety reasons. The wax is placed in a dropping point cup, and as it is heated, the temperature at which it drops is recorded.

The test is significant because the melting point of wax is an important property for consumers and can indicate the performance characteristics of the wax. The results from the ASTM D127 test are often used to assess the melting characteristics of the waxes in question.

The values stated in the standard are in SI units and are considered the standard values, with any values in parentheses provided for information only. The standard also emphasizes the responsibility of the user to establish appropriate safety, health, and environmental practices and to determine the applicability of regulatory limitations prior to use.

 

The drop melting point of wax is a critical parameter that has significant implications for various wax applications. Here's why it's important:

  1. Quality Control: The drop melting point serves as a quality control measure, ensuring that the wax meets the specifications required for its intended use. Consistency in melting point is essential for maintaining product quality and performance.

  2. Performance Characteristics: The melting point can indicate the performance properties of the wax. For instance, a higher melting point may suggest better heat resistance, which is important for applications where the wax is exposed to high temperatures.

  3. Manufacturing Processes: In manufacturing, the melting point of wax can affect the processing temperature, which is crucial for operations such as coating, laminating, or molding. Knowing the melting point helps in optimizing the process conditions for better efficiency and product quality.

  4. Product Formulation: In the formulation of products like cosmetics, pharmaceuticals, or candles, the melting point of the wax determines how the product will behave under different temperature conditions. It influences the choice of wax and other ingredients to achieve the desired texture, consistency, and melting profile.

  5. Safety and Regulatory Compliance: Certain applications may have regulatory requirements regarding the melting point of the wax used, especially in industries like food packaging or pharmaceuticals, where the safety of the end product is paramount.

  6. Storage and Transportation: Knowing the melting point helps in determining the appropriate storage and transportation conditions to prevent the wax from melting, which could lead to leakage or damage to the product.

  7. End-Use Performance: The melting point affects how a wax product will perform in its end-use environment. For example, in candles, a lower melting point wax may provide a better burn, while in hot-melt adhesives, a higher melting point ensures the adhesive remains stable at higher temperatures.

  8. Environmental Impact: The melting point can influence the wax's behavior in different environmental conditions, such as varying ambient temperatures, which is important for outdoor applications or products exposed to temperature fluctuations.

In summary, the drop melting point is a key property that influences the selection, performance, safety, and regulatory compliance of waxes in a wide range of applications, from industrial manufacturing to consumer products.
