Imidurea (also known as imidazolidinyl urea) is used as an antimicrobial agent and preservative in cosmetics and toiletries. It is very active against gram-positive and gramnegative bacteria as a synergist in combination with parabens. Imidazolidinyl urea is more active against bacteria than fungi and is often combined with parabens to provide a broadspectrum preservative system. This preservative is one of the most widely used preservative systems in the world. The United States (US) Food and Drug Administration (FDA) considers imidazolidinyl urea as one of the most common antimicrobial agents used in cosmetics. Due to its high water solubility, imidazolidinyl urea can be incorporated into almost all waterbased cosmetics, toiletries, and cold-mix formulations. It is present in a wide range of liquid and powder products such as baby lotion, skin cream, sunscreens, shampoos, eyeliners, blush, perfumes, deodorants, hair dyes, shaving cream, and face masks. Imidazolidinyl urea is permitted for use in personal care products in the European Union at a maximum concentration of 0.6%. In Japan, imidazolidinyl urea is allowed in rinse-off cosmetics such as shampoo, body wash, and facial cleanser at a maximum concentration of 0.3%. Imidurea is an ingredient in ketoconazole 2% shampoo, indicated for the treatment of tinea (pityriasis) versicolor caused by or presumed to be caused by Pityrosporum orbiculare (also known as Malassezia furfur or M. orbiculare).
