IMIDAZOLIDINONE

Description

Imidazolidinone is a versatile compound widely used in cosmetic and personal care formulations. This synthetic ingredient serves primarily as a preservative, helping to extend the shelf life of products by inhibiting microbial growth. Its chemical structure, consisting of a five-membered ring containing two nitrogen atoms, enables it to effectively combat a broad spectrum of bacteria and fungi.

In skincare products, imidazolidinone is typically found in concentrations ranging from 0.1% to 0.6%. It is particularly valued for its stability across a wide pH range and its compatibility with various other cosmetic ingredients. This preservative is often used in water-based formulations such as lotions, creams, and liquid foundations.

While effective, imidazolidinone has been the subject of some controversy due to its potential to release formaldehyde, a known irritant and carcinogen, under certain conditions. As a result, some regulatory bodies have imposed restrictions on its use, and many formulators are exploring alternative preservation systems. Despite these concerns, when used within approved concentrations, imidazolidinone remains an important tool in maintaining product safety and integrity in the cosmetics industry.
