NOVELTY - Use of loess as a cosmetic material and raw material for soap, where the loess is prepared by: (a) pulverizing completely sun-dried natural loess; (b) introducing the pulverized loess in an earthenware container together with pine tree charcoal, paulownia wood material, alum and ginkgo leaves; (c) sealing the earthenware container; and (d) aging the materials at -5 - 40 degreesC for 1 - 6 months.    USE - As a cosmetic material and raw material for soap useful in facial pack and bathing composition (claimed); in prevention of arteriosclerosis and fat accumulation in human bodies; for the treatment of maturating diseases such as dermatophytosis, skin irritation, dermatitis and facial skin diseases and for stimulating metabolism and blood circulation system of the human body; and for prevention of aging and adult disease.    ADVANTAGE - The loess provides skin health-aid and cosmetic effects. The bathing composition makes a user feel refreshed, prevents arteriosclerosis and fat accumulation in human bodies; stimulates metabolism and blood circulation system of the human body; and is an environmental-friendly composition because the loess-containing water discharged after bathing flows into a draining path, thereby purifying a contaminated river and recovering contaminated soil. The facial pack includes loess having a fine particle size sufficient to avoid skin irritation and thus does not adversely affect the skin even if the user uses the pack everyday; has excellent moisturizing effect, generates less skin irritation and can removes sebaceous matters from the user's facial skin, thereby maintaining skin in a clean state, irrespective of oily and dry skin.
