A microemulsion for use in personnel care products, home care products and fabric care products which is clear and has particle sizes that are less than the wavelength of light, said microemulsion comprising, as essential components; (a) a substantially water insoluble quaternary ammonium salt containing at least one long-chain aliphatic C8-24 hydrocarbon group; (b) an oil or hydrophobic organic compound that is not dispersible in water on its own; and (c) a dispersant capable of preventing component (b) from coalescing into particle sizes that are above the wavelength of light, wherein the weight ratio of component (a) to component (b) to component (c) is from 2:0.5:0.4 to about 0.5:2:0.8. A clear, indefinitely dilutable microemulsion is obtained by quenching the same in water. |
