A humectant containing as the active ingredient a fraction of the parotid secretion of a mammal which precipitates from a water-miscible organic solvent at a concentration of 60 % (v/v) or higher; a method of moisturizing the skin, hair, and scalp by applying this humectant thereto; a cosmetic preparation comprising a cosmetic base and the above fraction; and a medicine comprising a base for medicinal external preparations and the above fraction. The humectant fraction derived from the parotid secretion of a mammal, used in the humectant, cosmetic preparation, and medicine, can perform its moisturizing function even in an extremely small amount to not only enhance the moisture-retaining function of the skin but improve the slip properties of the hair. Furthermore, it is safe for the human body.
