Patent Claims: 1. A topical composition, in the form of an emulsion, consisting essentially of an immunosupressant effective amount of 33-epi-chloro-33-desoxyascomycin, an alkanediol, ether diol, or diether alcohol containing up to 8 carbon atoms as solvent for the 33-epi-chloro-33-desoxyascomycin, a C.sub.8 -C.sub.22 unsaturated fatty alcohol, water, a liquid oil, a thickening agent, an emulsifier and a preservative.

2. A topical composition according to claim 1 in which the solvent is hexylene glycol or propylene glycol.

3. A topical composition according to claim 1 wherein the unsaturated fatty alcohol is oleyl alcohol or elaidic alcohol.

4. A topical composition according to claim 1 wherein the unsaturated fatty alcohol contains one, two or three double bonds.

5. A topical composition according to claim 1 wherein the unsaturated fatty alcohol contains one double bond.

6. A topical composition according to claim 1 wherein the double bond has a cis configuration.

7. A topical composition, in the form of an emulsion, consisting essentially of 33-epi-chloro-33-desoxyascomycin; an alkanediol, ether diol, or diether alcohol containing up to 8 carbon atoms as solvent for the 33-epi-chloro-33-desoxyascomycin; a C.sub.8 -C.sub.22 unsaturated fatty alcohol; water; a liquid oil; a thickening agent; an emulsifier; and a preservative, wherein the 33-epi-chloro-33-desoxyascomycin is present in the emulsion in an amount of about 0.01 to about 10% w/w.

8. A topical composition according to claim 7 wherein the 33-epi-chloro-33-desoxyascomycin is present in the emulsion in an amount of about 0.1 to about 1% w/w.

9. A topical composition according to claim 1 wherein the alkanediol solvent is selected from propylene glycol, butylene glycol, 2-ethyl-1,3-hexanediol and 2-methyl-2,4-pentanediol.

10. A topical composition according to claim 1 wherein the ether diol is selected from dipropylene glycol and diethylene glycol.

11. A topical composition according to claim 1 wherein the diether alcohol is diethylene glycol monoethyl ether.

12. A topical composition according to claim 1 wherein the unsaturated fatty alcohol is a lanolin alcohol or a C.sub.16 -C.sub.18 fatty alcohol.
