1. The purpose of this proposal is to propose a fluid composition that can form a lining, which is characterized by at least one effective amount of insecticide from natural sources selected from lactic acid and Monoclone in the solvent environment, 2. Latovrina and base oil containing an antiviral activity and / or its precursor, the viscosity of which is between 30 MPa and 40 PA / S；At temperature and pressure, environmental requirement 15: an effective procedure for providing bactericidal properties to all or part of the surface of a flexible or larger scaffold including at least one stage of the composition defined in claims 1 to 14. 18. Claim 18: a procedure developed in accordance with the above requirements, including at least the following stages: (a) flexible or larger scaffolds with a treatment area of at least one catalyst and / or one reactant capable of stimulating the interaction between uric acid and glycerin；(b) In accordance with claim 1, a surface is associated with a composition containing at least lactic acid and glycerin； and (c) a surface treated in accordance with claim B is heat treated in stages (b) and (c) continuously or simultaneously to facilitate the synthesis of a single Laurine.La presente tiene como objetivo proponer una composición fluida apta para formar un revestimiento, caracterizada porque contiene al menos en un medio disolvente una cantidad eficaz de al menos un viricida de origen natural seleccionado entre el ácido láurico, la monolaurina, la lactoferrina y los aceites esenciales que presentan una actividad antivírica y/o uno de sus precursores, poseyendo dicha composición una viscosidad comprendida entre 30 mPa.s y 40 Pa.s, a temperatura y presión ambiente.Reivindicación 15: Procedimiento útil para conferir una propiedades viricidas a todo o parte de la superficie de un soporte flexible o másico que comprende al menos la etapa que consiste en aplicar una composición tal como se define en las reivindicaciones 1 a 14.
