Topical hydrophobic composition and method
First Claim
Patent Images
1. A method of reducing drag of a swimmer relative to water comprising the steps of:
- before swimming, topically applying to body surfaces of a swimmer a dispersion of particles of hydrophobic metal oxide in a pharmacologically acceptable fluid carrier; and
removing the carrier to form a film of hydrophobic metal oxide particles on said surfaces.

Abstract
Drag is reduced during swimming by topically applying a film of rough particles of hydrophobic metal oxide such as organo silicon modified silicon oxide particles to certain skin surfaces of the swimmer. A uniform suspension of a long acting composition is formed by a mixture of 2 hydrophobic metal oxides in vaporizable liquid carrier such as ethanol containing a vaporizable plasticizer such as propylene glycol in which the amount of the larger hydrophobic metal oxide particles in the mixture predominates over the amount of smaller particles of hydrophobic metal oxide.
