[Topic] Human exposure [Comment] More information should be provided in the screening assessment with regards to the precise use-pattern of silica encapsulated pigments. [Response] 
Since silica encapsulation of pigments increases their heat stability and chemical resistance in plastics, they would likely be used in plastic processing requiring high temperatures. As noted in the screening assessment, these pigments, silica encapsulated or otherwise, are not used for the manufacture of products for use by the general population.
