These include ethyl cellulose, hydroxy ethyl cellulose, methyl cellulose, sodium carboxy methyl cellulose, and benzyl cellulose. Ethyl and benzyl cellulose can be used as hot-melt adhesives. Methyl cellulose is a tough material, completely non-toxic, tasteless, and odorless, which makes it a suitable adhesive for food packages. It is capable of forming high-viscosity solutions at very low concentrations, so it is useful as a thickening agent in water-soluble adhesives. Hydroxy ethyl cellulose and sodium carboxy methyl cellulose can also be used as thickeners. The cellulose ethers have fair to good resistance to dry heat. Water resistance varies from excellent for benzyl cellulose to poor for methyl cellulose. ... [Pg.73]

The zirconium chelates work with latexes containing sodium carboxy-methyl cellulose or cellulose ethers or polyvinyl alcohol, but in each case the pH of the paint must be carefully controlled. [Pg.143]

Cellulosic membranes are developed as a novel dmg delivery system, which is expressed to use on the skin and used as a mucus membrane of stomach, ear, nose, eye, rectum, and vagina. The goal excipients of these preparations are adhesive and film-former polymers. Modified cellulose, especially cellulose ethers, are extensively applied in bio-adhesives such as nasal, vaginal, ocular, buccal, and transdermal inventions only or by blend with additional polymers. Further newly applied ethers of cellulose in bio-adhesives contain anionic ether derivatives such as sodium carboxy-methyl cellulose (NaCMC) and non-ionic cellulose ethers such as hydoxypropyl cellulose (HPC), carboxymethyl cellulose (CMC), hydroxyethyl cellulose, ethyl cellulose (EC), hydroxylpropylmethyl cellulose (HPMC), or methyl cellulose (MC). Capability of polymer to absorb water from mucus and pH of objective area are main features defining the adhesive power of polymers. One benefit of cellulose ethers, such as HPC and NaCMC, is smaller dependence of adhesion period and their adhesion strength to pH of medium than thiolated bio-adhesive polymers and polyacrylate...

In drilling fluid applications, several types of viscosity modifiers can be used to enhance foam stablity. These include partially hydrolyzed polyacrylamide (PHPA) clays, such as bentonite xanthan gum guar gums starches cellulosic polymers, such as hydroxy ethyl cellulose (HEG) and sodium carboxy methyl cellulose (SCMC). In Table 8, base fluid viscosities and drainage times for one-half and four-fifths of the base fluids are recorded in a foam system consisting of an anionic foamer, sodium lauryl sulfate (SLS) and a nonionic foamer, TXlOO - ethoxylated octyl phenol. It can be seen that in these systems base fluid viscosity alone... [Pg.311]

In an investigation of various pol5miers, it was found that sodium carboxy methyl cellulose and versicol acted as strong retarders. For example, with the reference portland cement pastes, the peak in the conduction calorimetry occurred at 11 hours, and with versicol, the peak shifted to 20, 29, and 34 hours at dosages of 0.25, 0.50, and 0.75% respectively,...
