What are the key elements in viscous and liquid mixing for cosmetics?

• Raw material introduction – Raw materials can be integrated from the top of the mixer, directly through the emulsifier, or via automated or manual feeding, depending on the process setup and the characteristics of the raw materials.
• Mixing operations – emulsification, dispersion, dilution, or homogenization with the right tool , speed, and process parameters to achieve the right viscosity and texture for your products.
• Vacuum or pressure processing – optional use of vacuum or pressure for texture control, reduced mixing time, air removal, and handling delicate formulations.
• Reproducibility – strict control of temperature, shear, mixing time, and pressure for consistent quality, texture, and performance across batches.

Key features to look for when purchasing a viscous/liquid mixer

Here are key features to look for when selecting a viscous/liquid mixer in the cosmetics or pharmaceutical industry:

• Mixing tools
  Turbines, propellers, or emulsifiers, choose the right mixing tool for your product, and determine the number and type of agitation needed for your product (bottom, peripheral, central axial-flow)
• Process control
  Use smart interfaces to automate recipes, monitor batches, reduce human error and enable full tracetability.
• Capacity and scalability
  From lab-scale to full industrial production.
• Cleaning and sterilization
  Easy cleaning and CIP/SIP processes to prevent contamination.
• Safety and reliability
  Robust design for safe and long-lasting operation.
• Versatility
  Handle different products and formulations in the same mixer.
