N-[l,3-Bis(Hydroxymethyl)-2,5-Dioxo-4-Imidazolidinyl]-N,N'-Bis (Hydroxymethyl)-Urea. Acts as a preservative. It has a good bacteriostatic and bactericidal activity against a broad spectrum of gram-positive and gram-negative bacteria. It is compatible with most cosmetic formulations and ingredients; it's not inactivated by non-ionic emulsifiers and proteins. Acts synergically with other preservatives, resulting in a preservative system which gives not only a wide range of protection, but also greater preservative capacity. Used in cosmetics products.

Hansen Solubility Parameters

[18.3, 22.3, 19.5]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Custom® D-Urea. A practical determination of these HSP values would provide higher certainty. Learn More.
