Imidazolidinyl Urea is a multi-functional ingredient that serves as a preservative, stabilizer, and humectant in cosmetic and personal care formulations. It is highly effective against bacteria, yeast, and mold and prevents their growth in cosmetics - extending the shelf life of products. It also stabilizes formulations and prevents the degradation of active ingredients. Further, this ingredient has moisture-retaining properties that help keep the skin hydrated. In its raw form, Imidazolidinyl Urea appears as a white to off-white crystalline powder and can be easily incorporated into a wide variety of cosmetic products. It is commonly found in products like moisturizers, sunscreens, shampoos/conditioners, and makeup.

What is IMIDAZOLIDINYL UREA used for?
Imidazolidinyl Urea is widely utilized in cosmetics and personal care products primarily as a preservative. It helps prevent microbial growth, extending the shelf life of formulations. Additionally, it acts as a stabilizer, maintaining the integrity of products by preventing the degradation of active ingredients. Its humectant properties allow it to retain moisture, benefiting formulations aimed at hydrating the skin. Overall, Imidazolidinyl Urea enhances product texture and longevity while ensuring safety and efficacy.
Origin
Imidazolidinyl Urea is synthesized through a chemical reaction between urea and imidazolidine. The process involves heating urea with imidazolidine under controlled conditions to facilitate the formation of the imidazolidinyl structure. The reaction typically occurs in an aqueous or solvent medium to ensure proper mixing and reaction efficiency. After the reaction, the product is purified to remove any unreacted materials and impurities.

SKIN CONDITIONINGSafety Profile
Imidazolidinyl Urea has a favorable safety profile in cosmetics, and it has been approved by regulatory bodies like the FDA and the European Commission for use in concentrations up to 0.6-1.0%. While it is effective as a preservative, some individuals with sensitive skin may experience mild irritation or allergic reactions. It is known to release small amounts of formaldehyde, a potential irritant, but typically within safe limits. Patch testing is recommended for those with sensitivities.
