A new class of water dispersions has been obtained through encapsulation by silica nanoparticles with polyvinyl alcohol. This form is more stable than the previous ones against freeze-thaw cycles. The new systems are advantageous over dry water in stability and contents of liquid water, being similar to the latter in the degree of liquid phase dispersion.
