Synthetically manufactured amorphous performance silica display the typical spectrum of an x-ray amorphous substance under x-ray analysis thus they do not contain any crystalline parts.
In Experiments on acute oral toxicity with rats showed an LD50 of 10.000 mg/kg.
No sensitization was apparent after Evonik performance silica were applied to the skin and mucous membranes of a rabbit. Concentrations for acute toxicity to fish (LC50, 96 h) and daphnia (EC50, 24 h) were above 10.000 mg/l, respectively.
Advice on safe handling
Working with performance silica may result in an electrostatic charge. For this reason, equipment and facilities employed must be grounded and/or rendered inert.
Based on currently applicable standards of Chemical Substance Legislation, the Hazardous Substance Advisory and Transportation Regulations, Evonik performance silica are not classified as dangerous substances or goods.
