The viscosity of the ink added a thickening agent increases, can improve the physical and chemical stability of the ink; due to the increased viscosity, rheology of the ink can be controlled at the time of printing; the pigment and filler in ink is not easy to precipitate, increasing the storage stability of the water-based ink.
Thickening agent is a cellulose-based material and (or) polyvinyl alcohol substances. Cellulose substances may be methyl cellulose, ethyl cellulose, hydroxymethyl cellulose, carboxymethyl cellulose, hydroxypropyl cellulose, Hydroxyethyl cellulose and hydroxypropylmethyl cellulose; polyvinyl alcohol material may be an or several species of polyethylene 400, 600, 800, 1000, 1600, 2000, 4000, 6000.

Production Methods
A purified form of cellulose is reacted with sodium hydroxide to produce a swollen alkali cellulose, which is chemically more reactive than untreated cellulose.
The alkali cellulose is then reacted with ethylene oxide to produce a series of hydroxyethyl cellulose ethers.
The manner in which ethylene oxide is added to cellulose can be described by two terms, the degree of substitution (DS) and the molar substitution (MS).
The DS designates the average number of hydroxyl positions on the anhydroglucose unit that have been reacted with ethylene oxide.
Since each anhydroglucose unit of the cellulose molecule has three hydroxyl groups, the maximum value for DS is 3.
TYLOSE H 300 P2 is defined as the average number of ethylene oxide molecules that have reacted with each anhydroglucose unit.
Once a hydroxyethyl group is attached to each unit, TYLOSE H 300 P2 can further react with additional groups in an end-to-end formation.
This reaction can continue and there is no theoretical limit for TYLOSE H 300 P2.
