TABLE 9.6 Effect of ethoxyl content and viscosity on selected solid state
properties of ethylcellulose CHAPTER 1010 Applied Statistics in Product
Development William R. Porter. Ethoxyl (wt %) Viscosity (cps) Crystallinity (%)
Melting point (°C).
Yihong Qiu, Yisheng Chen, Geoff G.Z. Zhang, 2009
The completely etherified material with a degree of substitution of 3 has an
ethoxyl content of 54.88%. This material has little strength and flexibility, is not
thermoplastic, has limited compatibility and solubility and is of no commercial
value.

The hydrophilic head group of AOES surfactants contains both the anionic sulfate
moiety and nonionic ethoxyl chain. Commercially available AOES surfactants are
often sold as a blend of surfactants with varying alkyl and ethoxyl chain ...
It is practically insoluble in water, in glycerin, and in propylene glycol, but is
soluble in varying proportions in certain organic solvents, depending on the
ethoxyl content. Ethyl Cellulose containing less than 46% to 48% of ethoxyl

Polymeric Materials Encyclopedia, Twelve Volume Set
Also from Table 1, it is clear that an increase of the percentage of ethoxyl groups
accompanied the increase in sodium hydroxide content (liquor ratio). This may
be explained as follows. Increasing the sodium hydroxide content from 1 to 5 ...

Soon after, Moore, Epstein, Brown, and Tidswell2 determined X values from
osmotic pressures of solutions of ethyl cellulose (48.2% ethoxyl, M„ = 58,000)
and estimated Hildebrand parameters from observation of the initial phase
separation (x ...

This latter is determined in a solvent consisting of a 4 : I ratio, by weight, of
toluene/ethanol, using ethyl cellulose samples dried for 30 min at l00'C. Table

Encyclopedia of Food and Color Additives
Ethyl cellulose is the ethyl ether of cellulose. It is synthesized from wood pulp or
cotton linters by treatment with alkali and ethyl chloride. The degree of
substitution of ethoxyl groups is 2.6, representing from 44 to 50% of the dry
weight.
