Problems solved by technology

However, in these technologies, in order to achieve the above-mentioned purpose, substances that are not necessary for the detergency performance are added. Although restrictions on the composition are necessary, there is concern that the detergency performance will be reduced while the loading capacity is increased.

Embodiment 1

[0129] Particles 1 were continuously charged into a Flexo Mix (manufactured by Powrex Corp., Model 160) at a rate of 300 kg / hour to obtain surfactant carrier particles 1 . At this time, the rotation speed of the stirring blade of the Flexo Mix was set at 3000 rpm, and no water-soluble medium was added.

Embodiment 2

[0131] Granules 1 were continuously fed into Flexo Mix (manufactured by Powrex Corp., Model 160) at a rate of 300 kg / hr. Water was sprayed at a rate of 3 kg / hour with the spray nozzle provided in the mixing cylinder of the Flexo Mix and mixed continuously to obtain surfactant carrier particles 2. At this time, the rotating speed of the stirring blade of Flexo Mix is ​​set at 3000rpm. Observing the surface of the surfactant carrier particle 2 with SEM, it can be seen that the coating film containing the water-soluble component is partially dissolved from the particle surface, exposing the pores ( figure 2 ).

Embodiment 3

[0133] Continuously feed pellets 1 into the Flexo Mix at a rate of 300 kg / h. Water was sprayed at a rate of 9 kg / hour with a spray nozzle provided in the mixing cylinder. 10 kg of the obtained granules were sent to an airflow dryer, and dried with hot air at 100° C. for 30 minutes to obtain surfactant carrier granules 3 with a water content of 5% by weight.

Abstract

A process for producing granules for supporting a surfactant thereon which comprises a step in which granules having on the surface thereof a coating film containing a water-soluble ingredient are treated so as to have a coating film deficiency; and a process for producing detergent particles which comprises the step of mixing a surfactant composition with the granules obtained by the above process, under such conditions that the surfactant composition is in a liquid state. By the former process, surfactant-supporting granules having improved supporting ability can be obtained without lowering the detergency. Use of these granules can give detergent particles having excellent detergency.

Description

technical field [0001] The present invention relates to a method for producing surfactant carrier granules for producing liquid surfactant-added detergent granules. And the present invention also relates to the method of using such surfactant carrier particles to manufacture detergent particles. technical background [0002] As a surfactant used in detergents, it is often used in a liquid state. For example, nonionic surfactants excellent in sebum removal ability are liquid or pasty at room temperature. Although most anionic surfactants are solid, they are always used in aqueous solution for convenience. [0003] As a method of using such a liquid surfactant in detergent powder, there is a method of supporting a composition containing the surfactant on the particles. In order to suppress the bleed-out of the surfactant, the granules used for this purpose preferably have a large absorption amount (carrying capacity) of the surfactant. When the surfactant cannot be fully l...
