What is claimed is: 1. A personal care composition in the form of an aqueous gel, comprising an effective amount of at least one active personal care ingredient in a vehicle, wherein the vehicle comprises from about 0.1 to 100% by weight, based on the weight of the vehicle, of polytrimethylene ether glycol, said composition being free from gelling agents other than polytrimethylene ether glycol. 2. The personal care composition of claim 1, wherein the vehicle comprises a solvent and from about 0.1 to about 99% by weight, based on the weight of the composition, of polytrimethylene ether glycol. 3. The personal care composition of claim 1, selected from the group consisting of skin care products, cosmetics, tooth pastes, deodorants, anti-perspirants, insect re-pellants, anesthetics, shampoos, hair conditioners, sun care products, shower gels, soaps, hair styling gels, hair anti-dandruff compositions, hair growth promoter compositions, hair colorant compositions, hair bleaching agent compositions, hair anti-frizzing agent compositions, hair relaxer compositions, shaving product compositions, lubricating gel compositions, spermicidal gel compositions, and skin cleaning compositions. 4. The personal care composition of claim 1, wherein the polytrimethylene ether glycol is formed from biologically-derived 1,3-propanediol. 5. A gel comprising at least about 10 wt % water and from about 10 to about 90% by weight of polytrimethylene ether glycol, based on the total weight of the gel, wherein the polytrimethylene ether glycol has a number average molecular weight of less than about 1000, and wherein at least 90% of the repeating units of the polytrimethylene glycol are trimethylene ether units, said gel being free from gelling agents other than polytrimethylene ether glycol. 6. The gel of claim 5, further comprising an active personal care ingredient. 7. The gel of claim 6, that is free from a gelling agent other than polytrimethylene ether glycol. 8. The gel of claim 5, which is non-flowable at about 25° C. or below. 9. The gel of claim 5, which is a flowable liquid at about 35° C. or higher. 10. The gel of claim 8, which is a flowable liquid at about 35° C. or higher. 11. The gel of claim 5, which becomes a liquid upon contact with human or animal skin. 12. The gel of claim 6, which is non-flowable at about 25° C. or below. 13. The gel of claim 6, which is a flowable liquid at about 35° C. or higher. 14. The gel of claim 13, which is a flowable liquid at about 35° C. or higher. 15. The gel of claim 6, which becomes a liquid upon contact with human or animal skin. 16. The gel of claim 5, selected from the group consisting of skin care products, cosmetics, tooth pastes, deodorants, antiperspirants, insect repellants, anesthetics, medicinal agents, shampoos, hair conditioners, sun care products, shower gels, soaps, hair styling gels, hair anti-dandruff compositions, hair growth promoter compositions, hair colorant compositions, hair bleaching agent compositions, hair anti-frizzing agent compositions, hair relaxer compositions, shaving product compositions, lubricating gel compositions, spermicide gel compositions, and skin cleaning compositions. 17. The gel of claim 5 wherein the polytrimethylene ether glycol is formed from biologically-derived 1,3-propanediol. 18. The gel of claim 6 wherein the polytrimethylene ether glycol is formed from biologically-derived 1,3-propanediol. 19. The gel of claim 11, wherein the polytrimethylene ether glycol is formed from biologically-derived 1,3-propanediol. 20. The gel of claim 15 wherein the polytrimethylene ether glycol is formed from biologically-derived 1,3-propanediol.
