Abstract

An allantoin-containing skin cream composition can comprise allantoin and at least one anionic or nonionic emulsifier that is substantially hydrophilic and is soluble in water. The composition is in the form of an oil-in-water emulsion. The pH of the composition is in a range of from about 3.0 to about 6.0; preferably, the pH of the composition is from about 5.0 to about 6.0. The composition can further comprise an acidic anionic polymer. A preferred acidic anionic polymer is a carboxypolymethylene polymer. The composition can further comprise a carbohydrate polymer such as galactoarabinan, polygalactose or polyarabinose. The composition can additionally comprise other ingredients such as herbal extracts, an antioxidant component, an emollient component, a chelator, a solvent component, or a preservative component. The composition is useful as a skin protectant.
