Diazolidinyl Urea

Description

Diazolidinyl Urea is a widely used antimicrobial preservative in cosmetic and personal care products. This synthetic compound is derived from allantoin and acts as a formaldehyde releaser, effectively inhibiting the growth of bacteria and fungi in various formulations. Its broad-spectrum antimicrobial activity makes it particularly useful in water-based products, where microbial contamination is a common concern.

Typically used at concentrations between 0.1% to 0.5%, Diazolidinyl Urea helps extend the shelf life of products by preventing microbial growth. It is often combined with other preservatives like parabens for enhanced efficacy. While generally considered safe for use in cosmetics by regulatory bodies, some individuals may experience skin sensitization or allergic reactions.

Diazolidinyl Urea is soluble in water and compatible with most cosmetic ingredients, making it versatile for use in lotions, creams, shampoos, and other personal care items. Its effectiveness in acidic to neutral pH ranges (2-9) further contributes to its widespread application. However, formulators should be aware of potential formaldehyde release and consider alternative preservatives for products marketed as "formaldehyde-free" or for consumers with specific sensitivities.
