Description
Imidazolidinyl Urea is a heterocyclic organic compound belonging to the family of substituted ureas. Its declared technical function is PRESERVATIVE, a category that encompasses substances incorporated into cosmetic products with the main purpose of inhibiting the growth of microorganisms such as bacteria, yeasts and molds during the shelf life of the product. In international nomenclature it is also identified as imidurea.
Under Regulation (EC) No 1223/2009 on cosmetic products, this ingredient is included in Annex V, reference 27, corresponding to the list of preservatives authorized for use in cosmetic products marketed in the European Union. The quantitative restriction established sets a maximum authorized concentration in the ready-for-use product of "0.6%". No specific restrictions relating to the type of cosmetic product are established, so its authorization applies generally within the framework of Annex V. No additional mandatory labelling warnings are provided in association with this regulatory entry, nor supplementary conditions of use beyond the concentration limit indicated. The ingredient does not appear with a harmonized classification as a CMR substance (carcinogenic, mutagenic or toxic for reproduction) under the CLP Regulation.
