Packing agent which changes its color on skin

Abstract

Abstract PURPOSE:To prepare a packing agent which changes its color to violet, etc. on the skin, by adding a specific amount of ferrous ion or ferric ion to the foundation coating liquid, and phenolic hydroxyl groups such as salicylic acid, pyridoxine hydrochloride, etc. to the packing material. CONSTITUTION:The foundation coating liquid for packing is compounded with 20-2,000ppm of ferrous ion (Fe<2+>) or ferric ion (Fe<3+>), and the packing materrial is compounded with a compound having phenolic hydroxyl groups such as salicylic acid, phyridoxine hydrochloride, etc. The additives for the above compositions may be reversed. When the packing material is applied to the skin coated with the foundation coating liquid, the color change of the packing material takes place. The color of the packing material on the skin can be controlled to reddish yellow or violet by the proper control or combination of the pH, and concentration of the contaminant iron ions, added iron ions, phenolic hydroxyl groups, etc.
