have been applied to marine oil spills for at least a half-century.
Workers who were likely exposed to dispersants
while cleaning up the 2010 Deepwater Horizon oil spill experienced a range of health symptoms including cough and wheeze, and skin and eye irritation, according to scientists at the National Institutes of Health (NIH).
are typically used to reduce the interfacial tension between crude oil and water and facilitate the breakup of oil slicks into small droplets that are thought to be more easily dispersed by natural processes such as wind and wave action (Chapman et al.
Structured polymers/non-ionic dispersants
(such as block copolymers) are frequently used for steric stabilization of nanoparticle dispersions.
such as Corexit 9500A were used to disperse oil both at the well-head and at the surface.
Air Products Materials Technologies segment introduced ZetaSperse 3800, its latest addition to its portfolio of polymeric dispersants
Our first-rate functional expertise with anti-scaling dispersants
, anti-soiling technologies, rheology modifiers, conditioning polymers, UV boosters and light management helps us develop new applications for our technologies in adjacent spaces.
Pigments are not readily dispersible in liquid vehicles and require dispersants
Included are rheology modifiers, foam control agents, wetting agents, dispersants
, and slip and rub materials.
Elaborating on the new aerial dispersant
delivery system platform, Lee says: After an offshore oil spill, dispersants
are sprayed on the affected area which help to break down the oil on a molecular level.
are the stabilizing agents in a pigment dispersion and are commonly based on polymeric, and often complex, structures.
ADM will begin distributing its proven range of dispersants
products in the EU, with the appointment of Hamburg-based chemical distribution company, Lehmann & Voss & Co.
