Abstract
The present invention relates to a method for preparing liquid surfactant-containing compositions in a sequential, continuous process which makes it possible to fill multi-chamber containers simultaneously with different compositions.
Claims19
A method for the continuous preparation of at least two different liquid, surfactant-containing compositions, in which method a flow of a master batch which has at least one surfactant and at least one solvent is continuously provided and this master batch cyclically goes through at least the following steps:
- a. adding at least one first additive to the flow of the master batch for a first length of time in order to obtain a first composition,
- and
- b. adding at least one second additive to the flow of the master batch for a second length of time in order to obtain a second composition,
- wherein the at least one first additive and the at least one second additive are different from one another and the first and second compositions are stored separately.
