ABSTRACT:
A method for making methylolated hydantoins by reacting a hydantoin, a formaldehyde such as paraformaldehyde and an alkaline catalyst at conditions of temperature and pressure sufficient to induce reaction to obtain a product in essentially 100% active form. Dry methylolated hydantoin product made by this process may be stored or shipped more economically than an aqueous solution containing a methylolated hydantoin.
