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.

Elles contiennent un indicateur de couleur oxydable et un peroxyde ou per-acide, ainsi qu'un stabilisateur pris dans la cyclodextrine, la nitrone ou des combinaisons des deux. Ces combinaisons servent d'ingrédients d'articles d'hygiène permettant de prédire l'approche de la menstruation. Elles produisent un signal visuel du fait de la détection du sang avant son apparition dans ces articles en quantités visibles.
