Abstract
Abstract A grip-improving gel, primarily for application to the skin, is disclosed. The gel includes a fine particle size silica, a compatible gelling agent for improving the adherence of the gel to the skin, and an aqueous solution of a C 1 to C 4 alcohol. In a highly preferred embodiment, the gelling agent comprises an organoclay compound or an organic derivative of a hydrous magnesium and/or aluminum silicate, and the fine particle size silica is hydrophobic, preferably being prepared by the reaction of a fumed silica with a silane.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
132 words
A grip-improving gel which comprises a fine particle size hydrophobic silica, said hydrophobic silica being formed from a reaction of silica with a silane, said silane having the general formula of SiR n X 4-n , wherein R comprises a lower alkyl, X comprises a halogen, and n is from 1 to 3, a minor amount of a compatible gelling agent for improving the adherence of said gel, said compatible gelling agent being selected from the group consisting of cellulose gums, hydrous magnesium and aluminum silicates, organic derivatives of the hydrous magnesium and the aluminum silicates, and mixtures thereof, and a major amount of an aqueous solution of a C 1 through C 4 alcohol, so that upon the application of said gel a thin, non-tacky, strongly adhering dry film is formed.
Claim 2
Dependent Claim
132 words
