between 0 1 and 25 preferably between 0 2 and 15 by weight the superabsorbent compositions of the invention gel upon contact with water aqueous saline solutions or body fluids as the superabsorbents of the prior art and the gels thus formed behave essentially identically thus one can use them instead of the ordinary superabsorbents in the manufacture of hygiene articles such as disposable diapers or disposable pants for babies children adults or the elderly of both sexes not suffering from any contraindication the zeolites exchanged with the metal ions ag cu 2 and zn 2 be justly considered as being harmless on the one hand because these ions are strongly attached to the inside of the zeolite structure and on the other hand because these ions are traditionally and widely used in antiseptic compositions for the skin flanamazinc u00ae and sicazine u00ae 1 1 silver sulfadiazine with a silver content of 0 3 dermocuivre u00ae copper sulfate at 0 2 zinc oxide at 10 the hygiene articles such as disposable diapers and disposable pants for babies and young children adults or elderly of both sexes containing these compositions are also the objects of the present invention the evaluation of the real efficacy of the antiodor products is a delicate matter however in a context of bacterial inhibitors to prevent the decomposition of urea into ammonia one can estimate the efficacy of the products of the invention on the one hand by their ability to limit or even eliminate bacterial development and on the other hand by the evolution of ammonia in the presence of various substances with which they are associated in the production of diapers and other sanitary articles in particular superabsorbent polymers the efficacy of these products is quantified here by counting the microorganism colonies per unit.
