The manufacture of lotion emulsions can be rather complex. The oils and waxes commonly found in hand and body lotions are hydrophobic and don’t stay in suspension for very long. Emulsifying agents and other additives are used to help form stable emulsions, but these can be costly and manufacturers want to use them sparingly.
There are 3 main target grease applications where Sonic’s Colloid Mills are used quite effectively.

Using a High Pressure Homogenizer for silicone emulsions is commonplace. Silicones and silicone fluids are so universally used that we come across them in everyday life without even knowing it. We see them in sealants, caulks, adhesives, lubricants, medicines, cleaning and shining products, electrical insulation and so on.
Using high pressure Homogenizers for titanium dioxide or zinc oxides is instrumental in the development of personal care products such as sunscreen and sunblock as well as in the chemical industry for paints, coatings and adhesives.
Mixing adhesives or, more specifically, emulsifying epoxies and resins is a key part of making adhesives with long shelf life, improved stability and performance.
