Methyl and hydroxyalkylmethylcelluloses are nonionic polymers soluble in cool water. Methylcellulose (MC), hydroxyethylmethylcellulose (HEMC), and hydroxypropylmethylcel-lulose (HPMC) do not interact with cations forming insoluble salts, but electrolytes that compete with MC for water can cause precipitation. 

Figure 2 illustrates the temperature dependence of the swelling degree as a function of precursor polymer type. Methylcellulose (MC), hydroxypropyl-methylcellulose, type E (HPMC-E) and hydroxypropylmethylcellulose, type K (HPMC-K) gels have comparable effective crosslink densities of about 2 x 10 5 mol/cm3 (as determined from uniaxial compression testing), while the crosslink density of the hydroxypropylcellulose (HPC) gel is about half this [52]. The transition temperature for each gel is within several degrees of the precursor polymer lower critical solution temperature (LCST), except for the MC gel, which has a transition temperature 9 °C higher than the LCST. The sharpness of the transition was about 3%/°C, except for the HPC gel transition, which was much sharper - about 8%/°C. 

It has been known for sometime(See Ref la) that NG will migrate from proplnts (double- or triple-base) into the combustible case and be absorbed by the NC, thus gelatinizing it. As this migration affects the physical props of the cartridge case, it should be prevented as much as possible. One of the methods to stop such migration is to coat the inside of cartridges with a barrier material. Axelrod found that a mixture of Methylcellulose (MC Std 15cps) 5.0,...

Substituted Cellulose Ethers. Since their introduction for ophthalmic use, MC and other substituted cellulose ethers such as hydroxyethylcellulose, hydroxypropylcel-lulose, hydroxypropyl methylcellulose (HPMC), and carboxymethylcellulose (CMC) have been used in artificial tear formulations.These colloids dissolve in water to produce colorless solutions of varying viscosity. They have the proper optical clarity, a refractive index similar to the cornea, and are nearly inert chemically. Their relative lack of toxicity, their viscous properties, and their beneficial effects on tear film stability have made cellulose ethers useful components of artificial tear preparations. Historically, the most frequently used representative of this group was MC.
