DESCRIPTION

Cellulose, Powdered, occurs as a white substance and consists of fibrous particles that may be compressed into self-binding tablets that disintegrate rapidly in water. It exists in various grades, exhibiting degrees of fineness ranging from a dense, free-flowing powder to a coarse, fluffy, nonflowing material. It is purified, mechanically disintegrated cellulose prepared by processing bleached cellulose obtained as a pulp from such fibrous materials as wood or cotton. It is insoluble in water, in dilute acids, and in nearly all organic solvents. It is slightly soluble in 1 N sodium hydroxide.
