Stable gel compositions comprising a water-soluble salt of carboxymethyl cellulose wetted by or dispersed in a hydrophilic organic liquid such as glycerol, methanol acetone or the like and an aqueous solution of a water-soluble polyvalent metal salt such as potassium alum, ferric chloride, cupric chloride or the like, which are useful as bases for many preparations of medicines, cosmetics and the like.

Stable gel composition containing a carboxymethyl cellulose salt and a

Water is effectively removed out of an organic liquid by filtering the organic liquid with a highly water-absorptive sheet which has been prepared from an alkali metal salt of fibrous carboxymethylcellulose.

Dehydrating method

A cellulose nitrate having a degree of nitration of from 12.2% to 14.1% in terms of the nitrogen content and a degree of polymerization of from 100 to 1,000 is suitable to prepare a low-melting glass paste.

Low-melting glass paste and cellulose nitrate therefor

A process for producing sodium carboxymethylcellulose having an excellent dispersibility in water by heat-treating sodium carboxymethylcellulose to crosslink the same. The starting sodium carboxymethylcellulose has an equivalent ratio of the free carboxylic acid group to the sodium carboxylate of at least 0.01 to 100 and a viscosity of at least 100 cP (as a 1% aqueous solution).
