Abstract

The invention pertains to enhancing the dispersion on the surface of a polar liquid, such as water, of particles of a powder of the composition essentially comprising a mono-layer forming constituent, such as hexadecanol or octadecanol or a blend thereof, together with a high proportion of a soluble or sparingly soluble alkaline earth metal hydroxide, more particularly about five times the mono-layer forming constituents weight when the hydroxide constituent is -as preferred for potable water evaporation reduction -calcium hydroxide procured as inexpensive, pre-powdered agricu ltural hydrated lime. A melt processing manner of producing the composition is described. When particles of the composition contact the body of water, so long as lime remains present in any floating particles, they will be positively charged, resulting in their repulsion from one another. This enhanced dispersal effect is due to the ionization of the calcium hydroxide.
