1. **Appearance and form**
- **Color and transparency**: Emulsified wax is usually white or milky white, which is caused by the scattering of light by wax droplets in the emulsion. Its transparency is low, and it is generally translucent or opaque. However, some emulsified waxes that have been specially treated or contain specific additives may have a different appearance. For example, some high-purity emulsified waxes may be slightly light yellow, or appear in other colors when pigments are added.
- **State and fluidity**: It is a liquid substance with a certain fluidity. Its fluidity depends on factors such as the wax content, the type and amount of emulsifier, and the temperature of the emulsion. Generally speaking, when the wax content is low, the amount of emulsifier is high, and the temperature is high, the fluidity of the emulsified wax is better; otherwise, the fluidity will deteriorate. For example, in a low temperature environment, the emulsified wax may become more viscous or even partially solidify.

2. **Dispersibility**
- **Particle size**: The wax phase in the emulsified wax is dispersed in the water phase in the form of tiny particles. The particle size of these particles is usually between 0.1 and 10 μm, and the specific size varies depending on factors such as the emulsification process, the type of wax, and the performance of the emulsifier. Smaller particle size helps improve the stability and appearance quality of the emulsion. For example, emulsified wax with a particle size of less than 1 μm tends to have better transparency and stability.

3. **Density and specific gravity**
- The density of emulsified wax is generally between 0.9 and 1.0 g/cm³, which is slightly less than or similar to the density of water. Its specific density value will be affected by factors such as the type of wax, the wax content, and whether other ingredients are added. For example, an emulsified wax with a higher proportion of paraffin may have a density closer to 0.9 g/cm³, while if some denser additives are added, the density may increase.

4. **Viscosity**
- Viscosity is an important physical property of emulsified wax. Its viscosity range is wide, ranging from a few centipoise (cP) to thousands of centipoise. Emulsified wax has a higher viscosity when the wax content is high, the emulsifier content is low, or the temperature is low.

5. **Melting point and freezing point**
- Since emulsified wax is an emulsion of wax, the concepts of its melting point and freezing point are different from those of pure wax. Generally speaking, the melting point of emulsified wax is slightly lower than the melting point of the wax it contains, because the wax in the emulsified wax is in a dispersed state and is affected by the emulsifier. Its freezing point will also be lowered accordingly, and during the solidification process, the emulsion may stratify or demulsify.
