Application Number:	12/948,593
Patent Claims:	1. A method for treating a person with a skin disorder, comprising topically applying to the affected skin a non-aqueous composition comprising: (a) bis-(2-chloroethyl) methylamine or a pharmaceutically acceptable salt thereof; and (b) a pharmaceutically acceptable excipient, wherein: the bis-(2-chloroethyl)methylamine or pharmaceutically acceptable salt thereof is present in an amount of about 0.001% to about 2.0% by weight of the composition; the pharmaceutically acceptable excipient is a compound of the formula HOCH.sub.2CH.sub.2OCH.sub.2CH.sub.2OR.sub.79, wherein R.sub.79 is a linear alkyl group having 1-6 carbon atoms; and the skin disorder is psoriasis, mycosis fungoides, or alopecia. 2. The method of claim 1, wherein the bis-(2-chloroethyl)methylamine is in the form of an acid-addition or base-addition salt. 3. The method of claim 2, wherein the acid-addition salt is an HCl, HBr, HI, H.sub.2SO.sub.4, or HNO.sub.3 salt. 4. The method of claim 1, wherein the pharmaceutically acceptable excipient is a compound of the formula HOCH.sub.2CH.sub.2OCH.sub.2CH.sub.2OR.sub.79, wherein R.sub.79 is a linear alkyl group having 2 carbon atoms (ethoxy diglycol reagent). 5. The method of claim 1, wherein the bis-(2-chloroethyl)methylamine or pharmaceutically acceptable salt thereof is present in an amount of about 0.01% to about 0.04% by weight of the composition. 6. The method of claim 2, wherein the acid-addition salt is an HCl salt. 7. The method of claim 6, wherein the pharmaceutically acceptable excipient is a compound of the formula HOCH.sub.2CH.sub.2OCH.sub.2CH.sub.2OR.sub.79, wherein R.sub.79 is a linear alkyl group having 2 carbon atoms (ethoxy diglycol reagent). 8. The method of claim 1, wherein the skin disorder is mycosis fungoides. 9. The method of claim 1, wherein the skin disorder is psoriasis. 10. The method of claim 1, wherein the skin disorder is alopecia.
