What It Is Diazolidinyl Urea is used as a safe and effective preservative in a variety of cosmetic products.

Why It's Included This ingredient is used as a preservative in a variety of Arbonne's products. Preservatives are essential in maintaining the integrity of cosmetic formulations as they help inhibit the growth of yeast, mold and bacteria. Arbonne follows all CIR (Cosmetic Ingredient Review Board) recommended usage and concentration guidelines.

The Facts Reports have suggested that Diazolidinyl Urea is a formaldehyde releaser but there is no indication that the use of Diazolidinyl Urea as used in cosmetic products would release formaldehyde at concentrations that would exceed the limits recommended for formaldehyde. On the basis of clinical data, the CIR expert panel concluded that Diazolidinyl Urea is safe as a cosmetic ingredient up to a maximum concentration of 0.5%. In fact, RIPT (Repeat Insult Patch Tests) sensitization studies using cosmetic products at concentrations up to 0.4% on normal subjects were essentially negative.
