Provided is a process for preparing a sulfuric acid amine salt (I) represented by the formula (I), which is a neutralization compound between a sulfated compound having a long chain alkyl or alkenyl group and an amine having a long chain alkyl or alkenyl group, useful as softener. wherein R<SUP>31 </SUP>is a linear or branched C<SUB>18-36 </SUB>alkyl or alkenyl group, or a group represented by the formula R<SUP>36</SUP>-(OA)<SUB>n</SUB>- (wherein R<SUP>36 </SUP>is a linear or branched C<SUB>12-36 </SUB>alkyl or alkenyl group, OA is an oxyalkylene group having 2 to 4 carbon atoms and n is a number of from 0.1 to 10 on average), R<SUP>32 </SUP>is a is a linear or branched C<SUB>10-36</SUB>alkyl or alkenyl group, X is -CONH-, -NHCO-, -COO- or -OCO-, R<SUP>33 </SUP>is a linear or branched C<SUB>1-6 </SUB>alkylene group, R<SUP>34 </SUP>is a linear or branched C<SUB>1-6 </SUB>alkyl or hydroxyalkyl group, or a group represented by R<SUP>5</SUP>-[B-R<SUP>6</SUP>]<SUB>b</SUB>-, R<SUP>35 </SUP>is a linear or branched C<SUB>1-6 </SUB>alkyl or hydroxyalkyl group, wherein R<SUP>5 </SUP>is a linear or branched C<SUB>10-36 </SUB>alkyl or alkenyl group, R<SUP>6 </SUP>is a linear or branched C<SUB>1-6 </SUB>alkylene group, B is a group selected from the group consisting of -COO-, -OCO-, -CCNH- and -NHCO-, b is a number of 0 or 1 and m is a number of 0 or 1. A sulfonic acid amine salt may be obtained.
