1. A composition for rendering a keratin fiber water-repellant comprising:
(a) a first hydrophobic particulate material consisting of octylsilyl-functionalized fumed alumina; (b) a second hydrophobic particulate material comprising substantially spherical particles of a polymer, said second hydrophobic particulate material having a coefficient of dynamic friction less than 0.5 and selected from the group consisting of polyethylene, polypropylene, polytetrafluoroethylene (PTFE), polyvinylchloride (PVC), polyvinyledenefluoride (PVDF), polyamide-imide, polymethylmethacrylate (PMMA), polyetheretherketone (PEEK), polyethylene terephthalate polyester (PETP), polystyrene, polydimethylsiloxanes polymethylsilsesquioxane, polyamide powder, Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer, silicone elastomer, Polysilicones, and combinations thereof; (c) optionally, a film former, (d) optionally, at least one other active or inactive agent, and (e) a volatile solvent; wherein said first and second hydrophobic particulate materials are collectively from about 0.01% to about 10% by weight, based on the entire weight of the composition; wherein the weight ratio of said first hydrophobic particulate material to said second hydrophobic particulate material is from about 1:10 to about 10:1; and wherein the aggregate weight percentage of all non-volatile liquid constituents in said composition is less than 10%, based on the entire weight of the composition. |
