Diazolidinyl Urea

Diazolidinyl urea is a common preservative used in many cosmetic and personal care products. It works by slowly releasing formaldehyde, which prevents the growth of bacteria, yeast, and mold. This helps to extend the shelf life of products and protect consumers from contamination.
