Zusammenfassung: | The invention relates to a biofilm-marking composition characterised in that it comprises: between 0.1 wt. % and 1 wt.%, inclusive of both limits, in relation to the total weight of the composition, of at least one tincture agent, preferably Rhodamine; at least one non-ionic surfactant; at least one anionic surfactant; at least one chelating agent; and water; mixed in different concentrations. The invention also relates to a biofilm-marking spray or aerosol containing said composition, in any of the variants thereof, and to a method for visually identifying said biofilms on surfaces, said method involving bringing the biofilm-marking composition according to the invention into contact with a surface to be analysed, and lightening the surface with a polar solvent. The dye remains adhered to the biofilm and the presence of the biofilm on the surface can be visually identified.
La presente invención se refiere a una composición marcadora de biofilms caracterizada por que comprende: al menos un agente de tinción, que preferiblemente es Rodamina, en un porcentaje en peso respecto al peso total de la composición comprendido entre 0,1% y 1% incluidos ambos límites; al menos un tensioactivo no iónico; al menos un tensioactivo aniónico; al menos un agente quelante, y agua mezclados en diferentes concentraciones. Asimismo, la presente invención engloba un spray o aerosol marcador de biofilms en superficies que contiene la composición referida, en cualquiera de sus variantes, y un procedimiento para identificar visualmente dichos biofilms en superficies que comprende contactar la composición marcadora de biofilms objeto de la invención con una superficie a analizar, y aclarar la superficie con un solvente polar. El tinte queda adherido al biofilm, pudiendo identificar visualmente su presencia en la superficie. |
