Abstract
Abstract A hair-waving composition which comprises (A) at least one main waving agent selected from sulfites and bisulfites and (B) at least one wave accelerating agent selected from alkylene carbonates of the general formula: R1R3 ANGLE C--C ANGLE (I) R2¦¦R4 ¦¦ OO ANGLE C PARALLEL O wherein R1, R2, R3 and R4 each stand independently for hydrogen atom, methyl group, ethyl group, hydroxyethyl group or hydroxy methyl group, alkyl carbamates of the general formula: R1 ANGLE N-COOR3 (II) R2 wherein R1, R2 and R3 each stand independently for hydrogen atom, methyl group, ethyl group or propyl group, and gamma - or delta -lactones of the general formula: (CH2)n ANGLE R1-CHCH-R2 ¦¦ (III) OCH-R3 ANGLE C PARALLEL O wherein R1, R2 and R3 each stand for hydrogen atom or methyl group, and n for an integer of 0 or 1. This composition can set strong permanent waves with greater safety within the pH range of human skin at a low temperature without any unpleasant odor.
