Abstract
Compounds of allantoin with basic amino acids have a solubility which is from about 25 to 50 times greater than that of pure allantoin. The compounds have almost the same pharmacological effects as allantoin and the basic amino acids and they are harmless. The compounds can be used in medicines, cosmetics, creams and ointments.
