  • Water-soluble detergent products in the format of a disposable portion pack for textile treatment in particular in the form of foil bags, so-called pouches, are known.
  • a portion pack is used for a one-time textile treatment application, usually within a textile washing machine.
  • the detergent product has a foil bag with one or more bag chambers.
  • Consumer surveys and market research show that consumers generally prefer products with multiple chambers over products with only one or fewer chambers. In general, the popularity of such multi-chamber products in a unit dose format has increased significantly in recent years and now accounts for a significant market share in many European countries.
  • Each bag compartment of such detergent products contains a detergent preparation which contains detergent-active substances for textile treatment, in particular for textile laundry.
  • the use of several bag chambers opens up the possibility of separately storing different detergent preparations, which may react chemically with one another or are not stable in storage when mixed for other reasons.
  • the use of several, different detergent preparations within one washing process allows the release of several, functionally different detergent and/or additive substances, such as bleach, fabric softeners or fragrances.
  • the individual detergent preparations within the bag chambers can have the same or different consistency and are preferably of a liquid consistency, for example liquid, gel-like, pasty, wax-like, or of a solid consistency, for example powdery, granular-like, free-flowing or solid-like.
