When using High Shear Emulsifier to make carbomer, you need to pay attention to the following key points to ensure product quality and process efficiency:

1. Material preparation and pretreatment
Choose the appropriate carbomer model: Different models of carbomer have different viscosities and stabilities. The appropriate carbomer model should be selected according to the specific application requirements.
Material quality: Ensure that the deionized water, neutralizer and other auxiliary materials used are of high quality, and avoid using materials containing impurities or unqualified materials.
2. Dissolution and mixing
Dissolution process: Add carbomer to deionized water without stirring immediately, allowing the carbomer to absorb water naturally until no white powder or agglomerates are visible. This
process can be performed every other day to ensure full dissolution.
Adjust pH value: Add neutralizer to adjust pH value, generally controlled at around 7 to achieve thickening state. The proportion of neutralizer needs to be adjusted according to the model of carbomer and specific process requirements.
3. Vacuum emulsifier operation
Stir evenly: Use a round tool or disperser to stir evenly at low speed to ensure that there is no white mass in the solution.
Vacuum emulsification: Add the solution to the homogenizer and use a vacuum emulsifier for emulsification. This process requires sufficient vacuum to effectively remove the air in the gel.
Control the stirring speed and time: The speed and time during the stirring process will affect the stability of the carbomer gel. The stirring speed and time should be adjusted according to the specific situation to avoid too fast or too long stirring to cause the gel structure to be destroyed.
IV. Subsequent processing and quality control
Filtration: After emulsification is completed, undissolved carbomer and other impurities are removed by filtration to ensure the purity of the product.
Packaging and storage: Choose appropriate packaging materials to prevent the carbomer gel from being affected by external factors (such as light, moisture, etc.). When storing, follow the recommendations on the product manual and store it in a dry and cool place.
Stability test: The prepared carbomer gel is tested for stability, including pH stability, viscosity stability, etc., to ensure that the product quality meets the requirements.
V. Safety and environmental protection
Operation safety: When operating a vacuum emulsifier, it is necessary to follow safe operating procedures to ensure the safety of personnel and equipment.
Environmental protection measures: Waste generated during the preparation process must be properly handled in accordance with environmental protection requirements.
In summary, when using a vacuum emulsifier to make carbomer, attention should be paid to material preparation, dissolution and mixing, vacuum emulsifier operation, subsequent processing and quality control, as well as safety and environmental protection.

Through fine process control and strict quality management, high-quality and stable carbomer gel products can be prepared.
