Japanese Patent JP2016222868
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a water-insoluble carboxymethyl cellulose cation salt that has an excellent use feeling and washability when used in a cosmetic or the like.SOLUTION: Provided is a method for producing water-insoluble carboxymethyl cellulose cation salt comprising a step (I) of mixing a carboxymethyl cellulose alkali metal salt (A) and a multivalent cation-containing solution (B). The carboxymethyl cellulose alkali metal salt (A) is preferably solid. The cation contained in the multivalent cation-containing solution (B) is preferably 0.3 to 10 molar equivalents with respect to the carboxymethyl group in the carboxymethyl cellulose alkali metal salt (A).SELECTED DRAWING: None
