Abstract

A carrier strip in the form of a nonwoven, woven or knitted fabric made from natural and/or synthetic fibres, for use with foaming detergents, is loaded with antifoam active chemical substances. As a result of its compact packaging and ease of handling, no antifoam substances are released prior to use, prior to contact between the carrier and detergents. To this end, the folded carrier is packed in a sealed water soluble film and deploys its total surface only on contact with the detergents.
