Description of the Related Art Conventionally, it has been known to blend an inorganic pigment such as zinc oxide, aluminum silicate, titanium oxide, talc or the like into a lotion for the purpose of anti-inflammatory, astringent and skin conditioning effects. Is being done. Further, in order to make the cosmetic look beautiful, a multi-layer type lotion in which a colored pigment such as iron oxide or an aluminum lake of a tar pigment is mixed with an inorganic pigment portion is provided. However, when a colored pigment is mixed, there arises a problem that long-term storage stability and heat history are deteriorated due to a difference in specific gravity and electrification, and the pigment becomes uneven due to sunlight.

しまうという問題があった。[0003] On the other hand, it has long been known that when gold fine particles are adsorbed on the surface of an individual, the surface is colored reddish purple, and this has been used variously for coloring glass and ceramics. Japanese Patent Application Laid-Open No. 1-215865 discloses a cosmetic containing a purple pigment having a carrier surface coated with gold, and Japanese Patent Application Laid-Open No. 2-104512 discloses a cosmetic containing an oxide immobilizing ultrafine gold particles. ing. However, these are all treated in the same manner as the red inorganic pigment, and when this is applied to a multilayer type lotion,
There is a problem that the density becomes non-uniform due to a difference in specific gravity between the pigment and the extender.
