Abstract (en)

[origin: EP2277985A1] A method for producing particles for supporting a surfactant having a bulk density of 550 g/l or less, including the following steps 1(a) and 2: Step 1(a): mixing a clay mineral powder and a powder raw material excluding the clay mineral, the powder raw material having an oil-absorbing ability of 0.4 ml/g or more; and Step 2: adding water or an aqueous binder solution to a mixed powder obtained in the step 1(a), and forming particles with a low-shearing granulator. According to the present invention, particles for supporting a surfactant having excellent supporting capacity/supporting ability/absorbing rate of a liquid surfactant composition can be obtained by a method without employing spray-drying.
