October 8, 2008: Particle Sciences has sold T-COTE, its proprietary line of microfine titanium dioxide, to Sensient, which assumes all marketing and sales responsibilities and acquires the associated trademarks and existing business. Particle Sciences will remain involved during the transition for technical support. The sale does not result in any change to the product, its specifications, or method and location of manufacture.
Particle Sciences has been a pioneer in nanotechnology. Its staff invented, among other things, Z-COTE, a microfine zinc oxide product sold to BASF in 1999. These pigments are primarily used as sunscreens; Particle Sciences also developed several surface treatments for these and other particles.
“Particle Sciences has been at the cutting edge of fine particle technology for some time. We have a history of developing commercially successful products for ourselves and others,” said Garry Gwozdz, director of formulation services at the company.
The sale is in keeping with Particle Sciences growth plan as it focuses on its pharmaceutical development services, according to Robert Lee, VP pharmaceutical development.
