Abstract
Abstract Monomeric, dimeric and polymeric allantoinformal- dehyde condensation products, especially imidazolidinyl urea and diazolidinyl urea, have been found to be therapeutically effective in the treatment of humans and animals, especially in the treatment of diseases and malconditions of the skin and other membranes. The compounds have the advantages of water-solubility, low toxicity, low irritancy and broad action, which is a combination of properties not found in many drugs. The compounds may be used in a wide variety of compositions and formulations.
