A storage-stable biocidal aerated gel composition comprises from 30 to 97 % by weight of water, from 0.2 to 5 % by weight of a gelling agent selected from xanthan gum, sodium alginate and neutralised carboxyvinyl polymer from 2 to 5% by weight of a fine particulate, hydrophobic silicone-treated silica having a surface area of from 80 to 300 m2/g and from 0.004 to 20 % by weight of a biocide which said composition is in the form of fine particles of an aqueous gel containing the water, gelling agent and the biocide, the surfaces of which fine particles are coated with a coating of the finely particulate hydrophobic silica. The biocidal aerated gel composition can be used to control pests using one or more appropriate biocides in the composition.
L'invention concerne une composition d'aérogel biocide stable au stockage, comprenant entre 30 et 97 % en poids d'eau, enter 0,2 et 5 % en poids d'agent gélifiant sélectionné parmi gomme de xanthane, alginate de sodium et polymère carboxyvinylique neutralisé, entre 2 et 5 % en poids d'un silice hydrophobe traité par silicone, à fines particules, ayant une surface active allant de 80 à 300 m?2¿/g et entre 0,004 et 20 % en poids d'un biocide. Ladite composition se présente sous forme de gel aqueux à fines particules contenant de l'eau, l'agent gélifiant et le biocide, dont les surfaces des fines particules sont munies d'un revêtement de silice hydrophobe à fines particules. La composition d'aérogel biocide peut s'utiliser pour lutter contre les parasites, au moyen d'un ou de plusieurs biocides appropriés de ladite composition.
