Abstract

Articles for limiting the foaming of detergent compsns. in washing machines comprise (a) a water-insol., non-divided support capable of physically absorbing an antifoam agent and (b) an amt. of absorbed antifoam agent of 1-200 wt. % on the support. Pref. the support is a (nonwoven) fabric made from natural, artificial or synthetic fibres such as cellulosic fibres, vinyl fibres, cotton, etc., impregnated with 20-80% of an antifoam agent such as an organopolysiloxane with R-SiO-R' units in which R and R' are 7C hydrocarbon groups, esp. dimethylsiloxane. The antifoam article is generally added in a quantity sufficient to give an amt. of antifoam agent of 0.05-5 wt. % on wt. of detergent compsn. present.
