  • the 4 silicones were formulated in each of the 6 formulations (A-F). Samples from each formulation were taken and added to a 1 cm cuvette and measured by UV-Vis, with readings taken at 500nm. This UV-Vis measurement gives the level of the haze of the product. A lower reading indicates less haze.
  • anionic silicone (silicone 1 ) that is functionalised by mid chain anionic substituents, and moreover doesn't contain a terminal anionic silicone group shows the best stability in terms of reduced haze, in comparison to a non-anionic silicone (silicone X) and anionic silicones that have a terminal anionic group (silicones Y and Z).
