Dow Corning Recommends Homogenizer for Silicone Emulsions

Home/Homogenizer, Process Systems/Dow Corning Recommends Homogenizer for Silicone Emulsions

Dow Corning, a major producer of silicone for the chemical industry and personal care industry, recommends the Sonolator homogenizer for creating silicone emulsions. Below is an example of one of Dow’s “Beauty & Personal Care Solutions” brochure. The Sonolator is called out (see yellow highlight) by name in this brochure discussing formulation tips for Dow Corning 9040 Silicone Elastomer Blend.

Sonic has been custom designing Sonolator homogenizers for silicone emulsion products for over 50 years. So, it should not be a surprise that the leading manufacturers of silicone recommend the Sonolator. However, it is still cool to see the Sonic’s system mentioned by name in Dow Corning’s literature. Sonic is very proud to have our equipment endorsed by Dow Corning and other great manufacturers.

Below is another piece of Dow Corning’s literature outlining specific instructions “Making Oil-In-Water Emulsions of Dow Corning Polysiloxanes.” Again, I have highlighted the pertinent areas of the literature. Note that not only does Dow recommend the Sonolator, but they also give specifics on operating pressure (80-100 bar) and resulting particle size of less than 1 micron. Additionally, if you will notice in the next section using a generic homogenizer the recommended operating pressure is “…maximum pressure (800 bar).” This is a great example of what Sonic always advises, the efficiency of the Sonolator as compared to standard homogenizer is much greater. In this case, it is very clear that significantly lower operating pressures mean less HP and therefore less electricity used over the life of the Sonolator system operation.

Another major difference between the Sonolator homogenizer and a generic homogenizer is Sonic’s commitment to custom designed mixing solutions. Sonic does not ask its customers to live with or fit their applicaiton into an off-the-shelf design. The Sonolator system is custom designed to meet not only the application needs, but also the needs of the engineers and plant manager. For example, if the plant is standardized on Allen Bradley control components or E&H or Micromotion flow meters Sonic custom build a system to meet all of the necessary requirements.

Below is an example of a custom designed Lexan box covering the high pressure portion of a Sonolator system. This box was designed to protect operators from a hazardous process chemical. In case an o-ring burst on one of the high pressure fittings this box will contain the hazardous chemical while the operators shut down the system, clean up the material, repair the o-ring and restart the processs. The Lexan box allows for easy access to the unit via thumb screws. The customer is very happy with this custom design. While this treatment will not be necessary for silicone emulsions it provides a good example of Sonic’s ability to provide custom solutions to any mixing application.

In closing, it is always great to see that Sonic’s experience and designs are recognized by other leading manufacturers. Sonic is happy to support Dow Corning’s customers and their operations creating silicone emulsions.
