(57) [Summary] [Problems] Glycerin, fatty acid esters, paraffins, quaternary ammonium salts, etc. are used as softening agents for paper such as toilet paper and tissue paper, but they are not used in large amounts. However, there were problems such as the inability to impart flexibility and the water absorption of papers and the high skin irritation, and none of these were satisfactory. SOLUTION: The paper treating agent of the present invention is characterized by containing a sulfosuccinic acid diester salt represented by the following formula (1). In the paper treating agent of the present invention, R 1 O and R 2 O in the formula (1) are alcohol residues having 12 to 24 carbon atoms, and ethylene oxide is added to an alcohol having 12 to 24 carbon atoms on average of 1 to 20 mol addition polymerization. It is preferable that the composition contains a sulfosuccinic acid diester salt which is any of the ethylene oxide adduct residues of alcohol. Embedded image |
