Abstract: The invention provides an odor removal composition characterized by:(a) a complexing agent selected from a biguanide polymer of the formula (1) ##STR1## in which R, R.sup.2, R.sup.2 and R.sup.3 are each a substituted or unsubstituted alkylene group having up to 12 carbon atoms in the main chain, HX is an acid; and n has a value of 2 to 20.(b) a carrier capable of assisting wetting of odor forming compositions; and(c) a cationic moiety; said moiety being part of a chemically independent compound, or chemically associated with a complexing agent or the carrier.
