imidazolidinyl urea

Rating:
Average
Categories:
Preservatives

Preservative considered weaker than its “cousin” diazolidinyl urea. Most often used with parabens because they work well together. Imidazolidinyl urea is considered a formaldehyde-releasing preservative. Although that sounds scary, the amount of formaldehyde released is well below the limits for safe exposure.
