Imidazolidinyl Urea

Overview

Imidazolidinyl urea is a fine, white, free-flowing powder that is highly hygroscopic, or water-loving, in nature.

This ingredient functions as a broad spectrum preservative, in that it protects skincare products against the growth of gram-negative bacteria, gram-positive bacteria, yeast and molds.

Imidazolidinyl urea is stable in a wide pH range and can be utilized in leave-on products, like lotions and creams, or rinse-off cleansing products. It is a very widely used preserving agent due to its efficacy and low cost.
