The cleansing agent is composed of a phosphate ester surfactant obtained by mixing two alkylphosphate salts a weight ratio of from 70:30 to 20:80. The first alkylphosphate salt is represented by: ##STR1## wherein R.sub.1 means a C.sub.12-14 hydrocarbon group, X denotes a specific cation, n1 is 0-10, A is R.sub.2 O--CH.sub.2 CH.sub.2 O).sub.n2 or --OY, R.sub.2 having the same meaning as R.sub.1, Y denoting a specific cation, and n2 being a value of 0-10. The second alkylphosphate salt is represented by: ##STR2## wherein R.sub.3 is similar to R.sub.1 and R.sub.2 except for inclusion of more carbon atoms, m1 is 0-10, B denotes R.sub.4 O-- --CH.sub.2 CH.sub.2 O).sub.m2 or --OY, R.sub.4 having the same meaning as R.sub.3, m2 being 0-10 and Y having the same meaning as defined above, X has the same meaning as defined above.
