DMDM hydantoin bụ ihe nchekwa na ihe ịchọ mma na ngwaahịa nlekọta onwe onye. Ọ na-arụ ọrụ site n'ibelata na igbochi mmebi na ngwaahịa dịka shampoos na ihe mkpuchi ntutu isi, na ngwaahịa nlekọta akpụkpọ ahụ dịka ihe na-eme ka akpụkpọ ahụ dị nro na ntọala etemeete. DMDM hydantoin bụkwa ihe na-egbochi nje bacteria eji eme ihe ịchọ mma na ngwaahịa nlekọta onwe onye.
