Temporary hair dyes containing a dispersant, titanium black, pigments and an alcoholic solvent, and processes of producing temporary hair dyes |
摘要 |
The present invention provides a temporary hairdye which is excellent in dispersion stability of a pigment even after storage over a long period of time by dispersing titanium black, which is safe to a human body, in alcohol having 4 or less carbon atoms, primarily ethanol by using an N-methacryloylethyl-N,N-dimethylammonium. alpha -N-methylcarboxybetain.butyl methacrylate copolymer. Further, there can be prepared a temporary hairdye which increases dispersion stability of the pigments and provides a different hue by subjecting titanium black and other pigments, particularly iron oxide type pigments such as iron oxide red, black iron oxide and yellow iron oxide to dispersion treatment together.
