Diazolidinyl Urea

Description

Diazolidinyl urea is a preservative which forms formaldehyde in cosmetic products. The formed formaldehyde protects the cosmetic composition from microbial influence. It is a preservative mainly used in cosmetic products, protecting them from bacteria, fungi and molds, which are known to cause spoilage. At concentrations usually used in cosmetic preparations, diazolidinyl urea is generally considered safe for use on skin. However, some people may experience problems due to sensitivity to formaldehyde released from the action of diazolidinyl urea as a preservative.
