Abstract
A skin cream composition containing allantoin and an emulsifier has improved stability coming from the adjustment of the pH to a range of 4.5 to 5.8. The lower pH preserves the stability of the allantoin and the functionality of the emulsifier system is maintained. The emulsifier system can be a nonionic emulsifier or an anionic emulsifier plus beeswax. The acid used to adjust the pH can be an organic acid or an inorganic acid. The composition can further comprise other ingredients such as herbal extracts, chelating agents, preservatives, emollients, solvents, and fragrance.
