Nomination Summary for Nanoscale Cellulose (N21304)
Nominated Substances: Microcrystalline cellulose
Nomination Date: 08/04/2010
Rationale: Anticipated increase in production due to natural abundance and functional properties that make it useful for a wide range of industrial applications; suspicion of toxicity based on known hazard of other respirable crystalline particles, high aspect ratio and large surface area of nanoscale form; very limited toxicological data available for nanoscale cellulose particularly via inhalation, the exposure route of greatest concern in industrial settings.
NTP Principles: not specified
