Health
Joinway cellulose ether products resemble the naturally occurring plant and seaweed gums in many of their chemical, physical, and functional properties. All these materials possess a basic carbohydrate structure.
Joinway products have had extensive evaluation and testing in both acute and long-term feeding studies in a number of species, including humans. Although dust from cellulose ether products could conceivably cause temporary mechanical irritation to the skin and eyes under extreme conditions and may be considered a nuisance dust if inhaled, the products are considered to present no significant health hazard in handling.
Please review the handling precautions within the Material Safety Data Sheet for more information.
Flammability
Cellulose ether products are organic polymers that will burn when exposed to heat and sufficient oxygen supply.
Fires can be extinguished by conventional means, avoiding any raising of dust by strong water jets. We recommends the use of water spray, carbon dioxide, or powder extinguisher.
