Patent Claims:	1. A topical composition for administration to skin, comprising the following ingredients: (a) a compound having the formula: said compound having the R stereoisomeric configuration at the 2 position and the R, S or RS stereoisomeric configuration at the 1′ and 3′ positions, or being a mixture thereof; (b) anhydrous ethanol; and (c) isopropyl myristate; wherein the compound of formula (2) is present in the composition in an anticholinergic effective amount; provided that said topical composition is anhydrous and comprises from about 1% to about 25% w/w of the compound of formula (2), said composition having greater storage stability after 7 days at 40° C. compared to a composition comprising an aqueous solvent or aqueous buffer, with the proviso that said ingredients are present in amounts such that the product of any transesterification is the same as the compound of formula (2), and with the proviso that said anhydrous ethanol is present in an amount sufficient to act as a non-aqueous solvent for the compound of formula (2). 2. The composition of claim 1, wherein the composition is formulated as a gel, cream, lotion, foam, patch, wipe, or emulsion. 3. The composition of claim 1, wherein the composition is formulated as a gel, cream, lotion, foam, or emulsion. 4. The composition of claim 1, wherein the composition is a topical anhydrous gel composition. 5. The composition of claim 1, comprising at least about 70% w/w anhydrous ethanol. 6. The composition of claim 1, comprising from about 70% to about 99.99% w/w anhydrous ethanol. 7. The composition of claim 1, comprising from about 70% to about 85% w/w anhydrous ethanol. 8. The composition of claim 1, wherein the compound of formula (2) is selected from the group consisting of: (ii) (2R) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (iii) (2R,3′R) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (iv) (2R,3′S) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (v) (2R, 1′R,3′S) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (vi) (2R, 1′S,3′S) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; (vii) (2R, 1′R,3′R) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; and (viii) (2R, 1′S,3′R) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide. 9. The composition of claim 1, wherein the compound of formula (2) is (2R, 3′R) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide. 10. The composition of claim 1, wherein the compound of formula (2) is at a concentration of from about 1% w/v or w/w to about 20% w/v or w/w of the composition. 11. The composition of claim 10, wherein the compound of formula (2) is at a concentration of from about 2% w/v or w/w to about 10% w/v or w/w of the composition. 12. The composition of claim 1, further comprising citric acid. 13. The composition of claim 1, further comprising hexylene glycol. 14. The composition of claim 1, further comprising citric acid and hexylene glycol. 15. The composition of claim 14, wherein the composition is a topical anhydrous gel composition. 16. A method of treating hyperhidrosis in a subject, said method comprising topically administering a composition as claimed in claim 1 to skin of an area of a subject suffering from hyperhidrosis. 17. The method of claim 16, wherein the compound is delivered to sweat glands in the skin of an anatomic area selected from a hand palm area, a foot plantar area, a groin area, an axilla area, and a facial area of the subject. 18. The method of claim 16, wherein: (a) the composition is a topical anhydrous gel composition; (b) the composition comprises at least about 70% w/w anhydrous ethanol; and (c) the composition comprises at least one gelling or viscosity-controlling ingredient. 19. The method of claim 18, wherein the compound is delivered to sweat glands in the skin of an anatomic area selected from a hand palm area, a foot plantar area, a groin area, an axilla area, and a facial area of the subject. 20. The method of claim 16, wherein said composition is a topical anhydrous gel composition comprising citric acid, hexylene glycol and at least one gelling or viscosity-controlling ingredient. 21. The method of claim 20, wherein the compound is delivered to sweat glands in the skin of an anatomic area selected from a hand palm area, a foot plantar area, a groin area, an axilla area, and a facial area of the subject. 22. The method of claim 21, wherein the gelling or viscosity-controlling ingredient comprises hydroxypropyl cellulose.
