The sunscreen composition of claim 6, wherein the at least one hydrophilic gelling agent is ammonium acryloyldimethyltaurate/steareth-25 methacrylate crosspolymer. 8. The sunscreen composition of claim 6, wherein the at least one hydrophilic gelling agent is present in an amount of from about 0.05 to about 1.5% by weight, based on the total weight of the composition. 9. The sunscreen composition of claim 6, wherein the at least one hydrophilic gelling agent is present in an amount of from about 0.1 to about 0.5% by weight, based on the total weight of the composition. 10. A method of protecting a keratinous substrate from UV radiation comprising applying onto a surface of the keratinous substrate a composition containing: (a) at least one oil- and water repellent emulsifier chosen from polyperfluoroethoxymethoxy difluoroethyl PEG phosphate;(b) at least one hydrophobically-modified emulsifier chosen from inulin lauryl carbamate; and(c) at least one hydrophilic gelling agent, and (d) sunscreen actives, and wherein the composition is water-resistant, while not requiring the use of a hydrophobic film-former, and is a stable emulsion. 11. The method of claim 10, wherein the at least one oil- and water repellent emulsifier of (a) is present in an amount of from about 0.05 to about 1.0% by weight, based on the total weight of the composition. 12. The method of claim 10, wherein the at least one hydrophobically-modified emulsifier of (b) is present in an amount of from about 0.1 to about 2.0% by weight, based on the total weight of the composition. 13. The sunscreen composition of claim 10, wherein the at least one hydrophilic gelling agent of (c) is chosen from carboxyvinyl polymers, polyacrylamides, 2-acrylamido-2-methylpropanesulfonic polymers and copolymers, cellulose-based derivatives, polysaccharides, gums, and mixtures thereof. 14. The method of claim 13, wherein the at least one hydrophilic gelling agent of (c) is present in an amount of from about 0.05 to about 1.5% by weight, based on the total weight of the composition.
