This limits the use of paraffin wax emulsions in applications requiring long-term durability.

However, paraffin wax emulsions are still widely used in short-term applications, such as polishes and basic protective coatings, where immediate performance is more important than long-term stability.

4. Factors Influencing Emulsion Stability

The stability of wax emulsions is influenced by several key factors, including particle size, emulsifier concentration, and environmental conditions such as temperature and humidity.

• Particle Size: Smaller wax particles in an emulsion generally lead to greater stability. In microcrystalline wax emulsions, the branched structure allows for the formation of smaller particles, enhancing stability. Paraffin wax emulsions, with their larger and more crystalline structure, are more prone to coalescence, which can lead to phase separation.
• Emulsifier Concentration: The concentration and type of emulsifiers used are critical to maintaining the stability of both wax emulsions. Non-ionic surfactants are often preferred for their ability to stabilize wax particles without reacting with other components. In paraffin wax emulsions, a higher concentration of emulsifiers is often required to compensate for the wax’s lower viscosity.
• Environmental Conditions: Stability can also be affected by changes in temperature, pH, and mechanical stress. Microcrystalline wax emulsions are more resilient to temperature fluctuations, while paraffin wax emulsions may separate at higher temperatures due to their lower melting point.
