    摘要: A cosmetic composition for skin use which comprises urea and a buffer comprising disodium hydrogenphosphate and citric acid or a buffer comprising potassium dihydrogenphosphate and disodium hydrogenphosphate, or both, and a cosmetic composition further comprising allantoin. Notwithstanding inclusion of urea which is useful for preventing rough dry skin and maintaining moisturization, the cosmetic composition does not have problems such as an increase in pH and an odor from ammonia produced by urea during storage for a long period of time.
