Claims
- 1. A method for treating material with a treatment composition which is comprised in a water-soluble pouch, involving the steps of:a) opening at least a part of the pouch and dispensing part of the treatment composition onto the material; b) adding the material of step a) and the remaining of the pouched treatment composition to an aqueous bath, thereby dispensing the remaining of the pouched treatment composition.
- 2. A method of claim 1 whereby the material is fabric and the aqueous bath is a washing machine.
- 3. A method as in claim 1 whereby the part of the treatment composition dispensed in step a) is liquid.
- 4. A method according to claim 3, wherein the liquid is a thixotropic liquid.
- 5. A method according to claim 1 whereby the in step a) the pouch is partially opened by means selected from cutting means, piercing means, or combinations thereof.
- 6. A method according to claim 1 whereby the pouch has at least two compartments, whereby in step a) at least one compartment, but not all compartments, is opened and whereby the compartment(s) opened in step a) comprises a liquid composition, whereby the compartment(s) not opened in step a) comprises a solid composition.
- 7. A method according to claim 1 whereby in step a) the part of the treatment composition is dispensed onto stains on the material and rubbed onto the stains.
- 8. A method according claim 1 whereby the pouch is made of a water-soluble film which is stretched.
- 9. A method according to claim 8 wherein the water soluble film is selected from the group consisting of polyvinyl alcohol films, derivatives of polyvinyl alcohol films, and mixtures thereof.
- 10. A method as in claim 3 whereby the pouched treatment composition is a unit-dose treatment composition, having at least a first compartment comprising a liquid composition to be opened is step a) and at least a second compartment which is not opened in step a), whereby the top wall of the second compartment is the bottom wall of the first compartment and the second compartment has side wall or side walls connected to the top with an internal angle of 60° to 120°, preferably 80° to 100°, or even preferably about 90°.
- 11. A method as in claim 10 whereby the pouched treatment composition is a laundry detergent and the second compartment has side wall or side walls connected to the top wall with an internal angle of about 90°.
- 12. A method as in claim 1 whereby the pouched treatment composition is a unit-dose treatment composition, and the treatment composition is divided over at least a first and a second compartment in the pouch, whereby the first compartment comprises a liquid composition to be opened in step a) and the first compartment is visibly different to the second compartment.
- 13. A method according to claim 12 wherein the first compartment is visibly different to the second compartment selected from the group consisting of having a different size, having a different shape, having a different color, and combinations thereof, than the second compartment.
- 14. A unit-dose pouched treatment composition, having at least a first compartment comprising a liquid composition and a second compartment comprising a solid composition, whereby the top wall of the second compartment is the bottom wall of the first compartment and the second compartment has side wall or side walls of a height of at least 1 cm wherein the side wall or side walls connect the top and bottom of said second compartment and the side wall or side walls are connected to the top wall with an internal angle of from 60°to 120°.
- 15. A unit-dose pouched treatment composition according to claim 14, whereby the liquid composition is thixotropic and contains a solvent and at least 20% by weight of said liquid composition, of surfactant.
- 16. A unit-dose pouched treatment composition according to claim 15 wherein the liquid composition has a pH of from 3 to 7.5.
- 17. A unit-dose pouched treatment composition as in claim 14, whereby the pouch comprises two compartments attached to one another, the first compartment having less than half the volume of the second compartment.
- 18. A unit-dose pouched treatment composition according to claim 14 having a skirt extending from at least one of the sides of the pouch.
