<p>The present invention relates to chemical compositions capable of blood detection which provide a visual signal in form of a color change. The compositions comprise an oxidisable color indicator and a peroxide or a per-acid and a stabilizer which is selected from cyclo-dextrin, nitrone or combinations thereof. These compositions are useful as ingredients of sanitary articles for the prediction of the approach of menstruation by providing a visual signal due to the detection of blood prior to the blood being contained in these articles in visually discernible quantities.</p> |
