【Fire Potential】
FIRE HAZARD: MODERATE, WHEN EXPOSED TO HEAT OR FLAME OR BY CHEMICAL REACTION WITH OXIDIZING AGENTS. FLAMMABILITY VARIES WITH DEGREE OF REPLACEMENT OF OH- RADICAL OF CELLULOSE BY ETHYL RADICALS.
PRECAUTIONS FOR MODERATE FIRE HAZARD SHOULD BE ADOPTED FOR SOLID MATERIAL. IT IS FREQUENTLY HANDLED AS PASTE OR A SOLN IN FLAMMABLE SOLVENT, WHEN PRECAUTIONS FOR FLAMMABLE LIQUIDS & VAPORS MAY HAVE TO BE OBSERVED.
【Formulations/Preparations】
To avoid brittleness, ethyl cellulose formulations usually include an antioxidant such as hydroquinone monobenzyl ether, 4-hexylpyrocatechol, or diphenylamine.
Grades: Technical; NF; FCC
Commercial product has ethoxy content of 43-50%
Most frequently used in solvent mixtures containing 60 to 80 percent aromatic hydrocarbon and 20 to 40 percent alcohol; this percentage of alcohol results in minimum viscosity. /Ethyl cellulose resins/
【Exposure Standards and Regulations】
Substances migrating to food from paper and paperboard products used in food packaging that are generally recognized as safe for their intended use, within section 409 of the Act. Ethyl cellulose is included on this list.
Ethyl cellulose is a food additive permitted for direct addition to food for human consumption, as long as 1) the quantity of the substance added to food does not exceed the amount reasonably required to accomplish its intended physical, nutritive, or other technical effect in food, and 2) any substance intended for use in or on food is of appropriate food grade and is prepared and handled as a food ingredient.
Ethyl cellulose is a food additive permitted in feed and drinking water of animals.
Certification of this color additive when used as a diluent in color additive mixtures for marking food is not necessary for the protection of the public health, and therefore batches thereof are exempt from the certification pursuant to section 721(c) of the act.
【Report】

Reported in EPA TSCA Inventory.

【Disposal Methods】
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
