Imidazolidinyl Urea
What is Imidazolidinyl Urea?
Imidazolidinyl Urea is a preservative commonly used in cosmetics and personal care products. It is synthesized through the reaction of allantoin and formaldehyde, leading to the formation of a compound that releases small amounts of formaldehyde over time to prevent microbial growth.
It is primarily used to extend the shelf life of products by preventing bacterial, yeast, and fungal contamination. Health concerns are primarily centered around its formaldehyde-releasing capability, however, regulatory bodies have set limits on use to ensure safety.
When you see this ingredient on a label, it's typically used to preserve the product's integrity and safety over time.
