SANITARY AID WITH ANTIBACTERIAL EFFECT FOR STABILIZATION OF PHYSIOLOGICAL BALANCE IN VAGINAL ENVIRONMENT AND/OR EXTERNAL GENITALIA

Abstract

A sanitary aid with antibacterial effect for stabilization of physiological balance in vaginal environment and/or external genitalia is made by a backsheet impermeable layer, absorbent core formed by a mixture of absorbent and/or superabsorbent and a topsheet layer from woven or non-woven textile or from cellulose. The sanitary aid contains an effective component on the basis of at least one reactive form of oxygen, which is encapsulated by an encapsulation agent, where the effective substance is arranged on the topsheet layer of the sanitary aid designated for the contact with body and/or in the absorbent core. The sanitary aid is adapted for gradual release of reactive forms of oxygen, particularly hydrogen peroxide after contact with liquid from the sanitary aid, which causes the prolongation of the effect of reactive forms of oxygen with substantial disinfection ability.
