When oil and water are liquids at the same time, they can be stirred at room temperature to achieve the emulsification effect. It can be seen that there is no strict limit on the temperature during the emulsification process. In general, the temperature of emulsification is determined by the melting point of the high melting point material contained in the two phases, the type of emulsifier, the solubility of the oil phase and the water phase, and other factors. But we can not ignore the emulsification temperature has a great influence on the result of emulsification. The temperature of the two phases should be kept close to the same state, especially for wax and fatty oil phase components with higher melting point, I .e. temperature above 70 ℃, when they are emulsified, low-temperature aqueous phase cannot be added to prevent milk

   When oil and water are liquids at the same time, they can be stirred at room temperature to achieve the emulsification effect. It can be seen that there is no strict limit on the temperature during the emulsification process. In general, the temperature of emulsification is determined by the melting point of the high melting point material contained in the two phases, the type of emulsifier, the solubility of the oil phase and the water phase, and other factors. But we can not ignore the emulsification temperature has a great influence on the result of emulsification.

The temperature of the two phases needs to be kept close to the same state, especially for those containing higher melting points, I .e.Above 70 ℃ like wax, fat and oil phase components, when they are emulsified, the low temperature water phase cannot be added to prevent the wax and fat from crystallizing out before emulsification, resulting in lumpy or rough uneven emulsion.

Generally speaking, when emulsifying, the temperature of oil and water can be controlled75 ℃ to 85 ℃, such as the oil phase has a high melting point of wax and other components, then the emulsification temperature will be higher. In addition, if the viscosity increases during the emulsification process, it will also affect the stirring, so it is necessary to appropriately increase the emulsification temperature. If the emulsifier used has a certain phase inversion temperature, then the laboratory vacuumCosmetic EquipmentThe emulsification temperature is also selected around the phase inversion temperature.

Emulsification temperature on the emulsion particle size will sometimes have an impact, such as the general use of fatty acid soap anionic emulsifier, with the primary soap method for emulsification, emulsification temperature control in.At 80°C, the emulsion particle size is about 1.8-2.0 μm. If emulsification is carried out at 60°C, the particle size is about 6 μm. In the case of emulsification with a nonionic emulsifier, the effect of the emulsification temperature on the particle size is relatively weak.

To get a better emulsification effect, in the whole.Cosmetic EquipmentDuring the emulsification process, attention must be paid to each operation detail to avoid being affected by uncertain factors.
