Hydantoin
Hydantoin, or glycolylurea, is a heterocyclic organic compound with the formula CH2C(O)NHC(O)NH. It is a colorless solid that arises from the reaction of glycolic acid and urea. It is an oxidized derivative of imidazolidine. In a more general sense, hydantoins can refer to groups or a class of compounds with the same ring structure as the parent compound. For example, phenytoin (mentioned below) has two phenyl groups substituted onto the number 5 carbon in a hydantoin molecule.

1. Your bubble bath is likely to contain potentially irritating detergents like sodium laureth sulphate and cocami–dopropyl betaine (the latter is also a penetration enhancer, allowing other chemicals to be more easily absorbed); preservatives such as tetrasodium EDTA, a potential irritant; and methylchloroisothiazolinone (both potential mutagens — substances that speed up gene mutation). If it contains cocamide EDTA (or similar compounds ending with DEA, TEA or MEA) along with formaldehyde–forming substances such as bronopol, DMDM hydantoin, diazo–lidinyl urea, imidazolidinyl urea and quaternium–15, it is likely to contain cancer–causing nitrosamines.
