摘要： This invention relates to a coated powder material containing a powder material having a surface layer that has been chemically immobilized with one or more surface-active agents and coated with an oil. The surface-active agents are present in an amount of at least about 0.1% by weight, based on the powder material; the oil is present in an amount ranging from about 0.1 to 180% by weight, based on the powder material; and the combined weight percentage of the surface-active agents and oil is at least about 4.0% by weight, based on the powder material. The oil-absorption rate of the powder material ranges from about 0.01 to about 0.70 gram of oil per gram of dry powder. The coated powder material is useful as a cosmetic.
