Description and Uses
imidazolidinyl urea is one of the most commonly used anti-bacterial preservatives given its low sensitizing potential. In 2010, it was the tenth most frequently used preservative in the united States (parabens ranged from first to sixth place). generally, imidazolidinyl urea is not used alone but as a copreservative with parabens for broad-spectrum activity. Although it may yield low levels of formaldehyde when subjected to destructive methods-such as exposure to high temperatures-under normal use conditions, there is no detection of free formaldehyde release. of all the formaldehydereleasing preservatives, imidazolidinyl urea is the one least likely to cause skin sensitization and allergic reactions.
