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.
Claims16
A silica silylate skin treatment kit comprising:
- at least two pluralities of silica silylate particles, each having an average maximum cross-sectional dimension;
- wherein the average maximum cross-sectional dimension of a first plurality of the at least two pluralities of silica silylate particles is about 0.5 mm to 1.5 mm;
- wherein the first plurality of the at least two pluralities of silica silylate particles represents at least about 99% of the volume of silica silylate particles in the container;
- 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.
