Low concentration surfactant emulsions and methods of making and using the same are disclosed herein. The emulsions have the benefit of employing less surfactant than conventional emulsions. Further, the emulsions are dilutable and retain their stability upon dilution. A benefit of the emulsions is that they leave a low residue, preferably no residue, on a surface after contact.

[EN] The invention provides inter alia a liquid electrostatic spray composition consisting of: (i) a non-aqueous component which is substantially free of propellants and ethanol; and (ii) 0.1-25% w/w water component being water as adjuvant to modify the viscosity and/or resistivity and/or surface tension of the composition optionally together with additional electrolytes; the composition containing one or more active ingredients; and the composition having at 20°C a resistivity in the range 1 x 103 to 1 x 106 Om, a viscosity in the range 1 to 5 cP and a surface tension in the range 20-40 mN/m. [FR] L'invention concerne entre autres une composition de pulvérisation électrostatique liquide contenant (i) un constituant non aqueux pratiquement exempt d'agents de propulsion et d'éthanol et (ii) entre 0,1 et 25% en poids d'un constituant aqueux, à savoir de l'eau, en tant qu'adjuvant afin de modifier la viscosité et/ou la résistivité et/ou la tension superficielle de la composition, facultativement au moyen d'électrolytes supplémentaires. Cette composition renferme au moins un ingrédient actif et présente à 20°C une résistivité comprise dans une fourchette de 1 x 103 à 1 x 106 Om, une viscosité allant de 1 à 5 cP, et une tension superficielle se situant entre 20 et 40 mN/m.
