TWO-PART HAIR DYE OR BLEACH COMPOSITION

摘要

The invention relates to an improvement in the foam quality and ejectabil ity in ejecting a mixed lotion composed of the first and second lotions cons tituting a two-pack type hair-dyeing or -bleaching preparation in the form o f foam by the use of a squeeze container. The two-pack type hair-dyeing or - bleaching preparation (1) of the invention comprises the first lotion (A1) c ontaining an alkali agent, the second lotion (A2) containing hydrogen peroxi de, and a squeeze container (6) for ejecting a mixed lotion (A3) composed of the first and second lotions (A1, A2) in the form of foam. The first lotion (A1) or the second lotion (A2) contains a foaming agent and the mixed lotio n (A3) exhibits a viscosity (at 25°C) of 1 to 100mPa s. The squeeze foamer ( 5) of the squeeze container (6) comprises a gas-liquid mixing chamber (12), a foam homogenizing means (14) for homogenizing the foam of the mixed lotion formed in the chamber (12), and an ejection opening (17) for ejecting the h omogenized foam and the ratio of the total volume of the first and second lo tions to the capacity of the container body is 0.30 to 0.60. In the body-par t cross section of the container body, the ratio of the mixer axis to the ma jor axis is adjusted to 0.50 to 1.0 with the area adjusted to 12 to 30cm2.
