ELECTROSTATIC AEROSOL COMPOSITIONS

An electrically neutral composition in the form of a water-in-oil or an oil-in-water emulsion is imparted with a unipolar electrostatic charge on spraying from an aerosol spray device by incorporating into the composition at least one polar or ionic or aromatic or linearly conjugated compound.

More Information
Summary:An electrically neutral composition in the form of a water-in-oil or an oil-in-water emulsion is imparted with a unipolar electrostatic charge on spraying from an aerosol spray device by incorporating into the composition at least one polar or ionic or aromatic or linearly conjugated compound. The amount of the polar or ionic or aromatic or linearly conjugated compound included in the composition is from 0.01 to 80% w/w based on a non-ionic surfactant also included in the composition, but is such that the theoretical conductivity of the emulsion is less than the bulk conductivity of the emulsion. Selon l'invention, on dote une composition, neutre sur le plan électrique et se présentant sous la forme d'une émulsion eau dans huile ou huile dans eau, d'une charge électrostatique unipolaire, lors de l'atomisation de celle-ci à partir d'un dispositif atomiseur, en incorporant dans la composition au moins un composé polaire ou ionique ou aromatique ou conjugué linéairement. La quantité de composé polaire ou ionique ou aromatique ou conjugué linéairement, incluse dans la composition, représente en pourcentage pondéral entre 0,01 et 80 % du poids d'un tensioactif non ionique également compris dans la composition, mais elle est telle que la conductivité théorique de l'émulsion est inférieure à la conductivité volumique de celle-ci.
