Velocys’ Smooth Emulsification Technology is Ready for Paint Application Testing

Published on 2011-03-21. Author : SpecialChem

A new emulsification technology based on the use of microchannel technology is now ready for testing in the commercial environment.

Emulsions and formulated products can be found in products for applications ranging from personal care and cosmetics to food and household chemicals to paints and adhesives. But many promising formulations do not make to the market because of the limitations of traditional mixing equipment used to create the necessary emulsions. A new emulsification technology based on the use of microchannel technology is now ready for testing in the commercial environment.

The technology, known as Smooth, and developed by Velocys, Inc. the US-based member of the UK-based Oxford Catalysts Group, has already been successfully tested in at the lab and pilot scale in devices that produce at rates of up to 5 litres per minute.

Traditionally, emulsions are formed in batches under high shear conditions using static mixers, ultrasound devises, homogenisers, or rotor/stator mixers. Ensuring consistent product quality using traditional methods can be problematic high speed mixers the high speed mixing process is difficult to control, leading to over shearing of sensitive materials and the need to use expensive surfactants. Microchannel emulsification takes advantage of a process known as laminar shearing - also known as laminar flow emulsification - to produce stable and uniform emulsified mixtures in a continuous stream, often without the need for surfactants.

Mark Grace, Product Manager, Smooth says: "The Smooth technology has produced excellent results in pilot scale trials carried out by a number of major players in the cosmetic and personal care industries. Now we're hoping to move on to the next stage, and run trials on the commercial scale."
