Abstract

Abstract A waving lotion for cold waving comprising: (i) a mercapto compound and (ii) an aqueous mixture obtained by heating (a) at least one compound selected from the group consisting of the compounds having the general formulae (I) to (XX), <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> wherein R1 is hydrogen or an electron attractive group, R2 is hydrogen or an alkyl group having 1 to 4 carbon atoms, and R3 is hydrogen, a hydroxyl group, or a methyl group and (b) at least one cyclodextrin selected from the group consisting of alpha , beta , gamma , and delta -cyclodextrins in an aqueous phase at a mole ratio of (a):(b)=1:9-1:1 at a temperature of 50 DEG C. to 100 DEG C. This waving lotion has no substantial mercaptan odor and generates no substantial or less of a mercaptan odor when applied to the hair.
