PURPOSE:A beauty pack agent showing properly the releasing period of a pack agent by change in color and providing beautiful feeling by chage in color, obtained by blending a beauty pack agent with a compound analogous to indolium type styryl compounds in acidic state with a hydrophilic base. CONSTITUTION:A pack agent which will be dried and solidified by evaporation of water is blended with a compound analogous to indolenium type styryl compounds shown by the formula I (R1 is alkoxycarbonyl, alkylsulfonyl, etc.; R2 is H or alkyl; R3 is H, alkyl, alkoxy, etc.; R4 and R5 are alkyl, hydroxyalkyl, etc.; X is anion) dissolved in a hydrophilic base (e.g., ethyl alcohol, etc.) in pH3.0-7.5 (preferably pH4.0-6.5), to give a color varnishing beauty pack agent. The compound analogous to indolium type styryl compounds shown by the formula I is obtained by blending a compound analogous to indolin type styryl compounds shown by the formula II with an acidic substance. |
