IMIDAZOLIDINYL UREA

Description

Imidazolidinyl urea is a widely used preservative in cosmetic and personal care products. This synthetic compound, derived from allantoin, plays a crucial role in preventing microbial growth and extending product shelf life. Its effectiveness against a broad spectrum of bacteria and fungi makes it a valuable ingredient in formulations ranging from moisturizers to shampoos.

Typically used at concentrations between 0.1% and 0.6%, imidazolidinyl urea is particularly effective when combined with other preservatives like parabens. It functions by releasing formaldehyde in small amounts over time, which inhibits microbial proliferation. This preservative is water-soluble and performs well in acidic to neutral pH environments.

While generally considered safe for use in cosmetics by regulatory bodies, some individuals may experience skin sensitization. It's important to note that imidazolidinyl urea is not recommended for use in products containing nitrosating agents, as this can lead to the formation of nitrosamines. As with any preservative, proper formulation and testing are essential to ensure product safety and efficacy. Manufacturers often choose imidazolidinyl urea for its stability, compatibility with other ingredients, and ability to maintain product integrity in various formulations.
