Adding Method of Emulsifier in Homogeneous Emulsifier


Release time:

2019-07-22

There are several ways to add emulsifiers: 1. Agent in the water phase method: the emulsifier is dissolved directly in water, and the oil is added under intense stirring. 2. Agent in oil phase method: add emulsifier to oil phase, add water to directly prepare W/O emulsion. If you want to obtain O/W type, continue to add water until deformation occurs, and transfer from internal phase to external phase, so that hydrophilicity-lipophilicity can reach proper balance and then emulsify, which is often better than direct emulsification effect. 3. Natural emulsification and dispersion method: add the required O/W emulsifier to the oil to make a solution. When in use, put the solution directly into a certain proportion of water, and stir a little to form O

There are several ways to add emulsifiers:
1. Agent in the water phase method: the emulsifier is directly dissolved in water, and the oil is added under intense stirring.
2. Agent in oil phase method: add emulsifier to oil phase, add water to directly prepare W/O emulsion. If you want to obtain O/W type, continue to add water until deformation occurs, and transfer from internal phase to external phase, so that hydrophilicity-lipophilicity can reach proper balance and then emulsify, which is often better than direct emulsification effect.
3. Natural emulsification dispersion method: add the required O/W emulsifier to the oil to make a solution. When in use, put the solution directly into a certain proportion of water, and stir slightly to form an O/W emulsion.
4. Take turns adding method: water and oil are added to the emulsifier in turn, adding only a small amount at a time.
5. The primary soap method: the fat is dissolved in wax, the alkali is dissolved in water, the two phase contact in the interface that soap is generated.
6.O-D emulsification method: emulsifier is dissolved in alcohol aqueous solution to form uniform and transparent intermediate phase D, added oil and solubilized to form lamellar liquid crystal, continued to add oil to form O-D emulsion, added water to form gel emulsion, continued to add water to gradually turn over to form O/W type micro emulsion. Because the solubility of emulsifier in oil is limited, compared with other methods, the choice of D a O emulsification method is helpful to the synergistic effect between the emulsifier and the emulsification effect.
