PROBLEM TO BE SOLVED: To make a color tone and a smell enjoyable while a bath agent dissolves by making a foaming bath agent be composed of a two-layer structure including an internal component and an external component, and making the two layers be different from each other in colors and smells.SOLUTION: A foaming bath agent is constituted of an internal component 1 and an external component 2 covering the internal component 1, the external component 2 is composed of a main bath ingredient 3 and an auxiliary bath ingredient 4 wherein carbonates and organic acids are compounded with each other as the main bath ingredient 3, and the internal component 1 has a color different from that of the external component 2 by compounding a colorant 5 (colors in the white range and in the bright color range, or a first pigment 5A is compounded with the internal component 1 and a second pigment 5B is compounded with the external component 2 wherein the color of the first pigment 5A and the color of the second pigment 5B are different from each other). In the foaming bath agent, a perfume 6 is added to at least one of the internal component 1 and the external component 2, and when perfumes are added to both components, a first perfume 6A is added to the internal component 1, and a second perfume 6B different from the first perfume 6A is added to the external component 2.COPYRIGHT: (C)2014,JPO&INPIT【課題】 発泡性浴用剤を内部構成物と外部構成物から成る二層構造とし、両層が異色で、且つ香りも異なるようにし、入浴剤が溶解する間に色調と香りを楽しめるようにした。【解決手段】 内部構成物1と、内部構成物1を被覆する外部構成物2とから構成され、外部構成物1は主浴用成分3と補助浴用成分4とから成り、主浴用成分3として炭酸塩類と有機酸類を配合し、内部構成物1は着色剤5の配合により外部構成物2と異色(白色系と有色系、或いは内部構成物1に第一色素5Aを、外部構成物1に第二色素5Bを配合し、第一色素5Aと第二色素5Bが異色である)であることを特徴とする。上記発泡性浴用剤において、内部構成物1と外部構成物2の少なくとも一方に香料6を添加し、両方に添加する場合、内部構成物1に第一香料6Aを、外部構成物2に第一香料6Aと異なる第二香料6Bを添加していることを特徴とする。【選択図】 図1
