ABSTRACT:
Cystamine is produced by a method which comprises reacting a 2,2-dialkyl thiazolidine represented by the general formula (1): ##STR1## wherein R.sup.1 and R.sup.2 independently are alkyl groups of 1 to 5 carbon atoms, with a peroxide in the presence of water. An alkylene oxide adduct of cystamine is produced by a method which comprises reacting the reaction mixture obtained as described above further with an alkylene oxide. These cystamine and alkylene oxide adduct of cystamine are useful as an additive for an aqueous lubricant.
