In 1959 Dodge s thesis under the supervision of Metzner was published at the same time as Shaver s findings under the supervision of Merrill. Both noticed unusually low friction factors for certain non-Newtonian solutions like those of sodium carboxy-methylcellulose in water. At around the same time, industrial researchers made similar observations with certain additives, the most prominent being guar gum, which is a polysaccharide derived from a plant. The gums were used to suspend sand in the sand-water mixtures utilized in oil-well fracturing operations. 

Their membrane consisted of sodium carboxy methylcellulose incorporated in viscose. 

A large number of papers on the effectiveness of sodium carboxy-methylcellulose as a washing agent have been published since 1947. The more pertinent studies are summarized in Table I, which indicates the type of detergent or soap used in each case. 

Sodium Carboxymethylcellulose Use sodium carboxy-methylcellulose (Hercules, Inc., CMC Type 7HF). 

Tablets for vaginal use have included hydroxypropylcellulose or sodium carboxy-methylcellulose and poly(acrylic acid) (such as Carbopol 934) as excipients. Micropatches in the size range fO-fOO,am in diameter prepared from starch, gelatin, albumin, collagen...

Nevertheless, simpler suspending and flavouring agents can also be prepared at the dispensary (e.g. methylcellulose 1%, or other celluloses such as hypromellose, microcrystalline cellulose, sodium carboxy-methylcellulose at 1-2%, xanthan gels, pharmacopoeial syrups, or mixtures of the above). In some formulations suspending agents may not be required, for example, when it is known that the drug is soluble... 

Viscosity versus shear stress for a 5.5% sodium carboxy-methylcellulose in water solution. Solid points are for bob-in-cup geometry, open points are vane-in-cup. From Barnes and Camali (1990). 

Many reports have appeared regarding complex formation for a variety of systems, such as nonionic and anionic surfactants with sodium carboxy-methylcellulose, anionic and cationic surfactants with nonionic poly-mers, SDS with methylcellulose and polyvinyl alcohol, and SDS with gelatin. Reports have also dealt with such topics as the effect of ionic surfactant counterions on complex formation,the dependence of folding and unfolding of polymers on the extent of binding, and the photochemistry of the complex. ...
