Liquid bleaching agent composition
 A transparent liquid bleaching agent composition having a transparent appearance and excellent storage stability and bleaching power, characterized by comprising hydrogen peroxide (a), a surfactant (b) and a bleach activator (c) capable of yielding an organic peracid when reacted with hydrogen peroxide and having a parameter .beta. of a mixed system consisting of the surfactant (b) and the bleach activator (c) as calculated according to the following equation of smaller than -2: ##EQU1## wherein C.sub.1 : the critical micelle concentration of the surfactant; PA1 C.sub.2 : the critical micelle concentration of the bleach activator; PA1 .alpha..sub.1 : the molar fraction of the surfactant in the whole mixed solute (molar fraction of added surfactant); PA1 .alpha..sub.2 : the molar fraction of the bleach activator in the whole mixed solute (molar fraction of added activator); PA1 C*: the critical micelle concentration of the PA1 X.sub.1 : the molar fraction of the surfactant in the mixed micelle; and PA1 X.sub.2 : the molar fraction of the bleach activator in the mixed micelle.
