The at least one particulate phase being brought into direct contact with at least one liquid composition, and to corresponding preparation methods.
Claims14
A washing and/or cleaning agent portion which comprises at least one chamber and a water-soluble wrapping, characterized in that the washing and/or cleaning agent portion comprises
- at least one particulate phase,
- at least one solid gel phase directly adjacent to the at least one particulate phase, the gel phase comprising as % wt of the gel phase:
- 8-26 wt. % polyethylene glycol having an average molecular weight of from 200-600 g/mol, 10-50 wt. % glycerol, 8-22 wt. % polyvinyl alcohol, and 10-50 wt. % C3-C5 alkanediol;
- wherein the at least one solid gel phase penetrates a maximum of 1 mm into interstices of the at least one particulate phase during a storage period of 4 weeks at 25° C.;
- and
- wherein at least one particulate phase is completely impregnated with at least one liquid composition.
A method for preparing washing and/or cleaning agent portions that contain a product comprising at least one particulate phase, comprising:
- a) providing a mold having at least one mold cavity, optionally containing at least one partition for dividing the base of the mold cavity;
- b) adding a water-soluble film to the mold cavity;
- c) forming at least one open chamber in the mold cavity by deforming the water-soluble film;
- d) adding to the open chamber at least one solid gel phase comprising as % wt of the gel phase:
- 8-26 wt. % polyethylene glycol having an average molecular weight of from 200-600 g/mol, 10-50 wt. % glycerol, 8-22 wt. % polyvinyl alcohol, and 10-50 wt. % C3-C5 alkanediol;
- e) adding to the open chamber at least one particulate phase so that the at least one particulate phase is directly adjacent to the at least one solid gel phase, wherein the at least one solid gel phase penetrates a maximum of 1 mm into the interstices of the directly adjacent particulate phase during a storage period of 4 weeks at 25° C.;
- f) adding to the open chamber at least one liquid composition, wherein the at least one particulate phase is completely impregnated with the at least one liquid composition;
- g) providing a second water-soluble film as a cover;
- h) superimposing the open chamber and the cover in order to seal the portion pack at a sealing region;
- and
- i) sealing the cover with the open chamber.
