Abstract
The present invention provides a method and kit for the treatment of surfaces, such as the skin surface of a user, to impart hydrophobic characteristics upon the surface. The treatment of surfaces to impart hydrophobicity protects equipment, personnel, and animals from the effects of aqueous solutions such as water, toxic slurries, concrete, acids and bases.
Claims20
A silica silylate skin treatment kit comprising:
- a first plurality of silica silylate particles of a first average size;
- a second plurality of silica silylate particles of a second average size;
- and
- a third plurality of silica silylate particles of a third average size;
- wherein the first average size is greater than the second average size;
- wherein the second average size is greater than the third average size;
- wherein the first plurality of silica silylate particles represent at least about 20% of the volume of silica silylate particles in the kit;
- wherein the silica silylate particles of the kit are not in a liquid composition;
- wherein the silica silylate has been rendered hydrophobic by reaction with a hydrophobe;
- and
- wherein the silica silylate particles are contained within a container comprising a plurality of apertures.
