|Anionic surfactant (linear alkylbenzene sulphonate) is preferred
|Flexible porous housing containing detergent composition (interior of the housing is coated with a bleach ingredient, an enzyme, a perfume, a fluorescer or mixtures thereof, preferably an enzyme)
|Housing helps to generate more foam, so less detergent composition is used and its cost performance is increased.
