An agent for permanent hair processing is disclosed that can shape the hair even in a neutral to slightly acidic pH region. The agent contains one or more compounds represented by the following formula (1) and/or formula (2): (1) wherein R1 is a hydrogen atom or an alkyl group of 1 to 5 carbon atoms, R2 is an alkoxyalkyl group having a total of 3 to 15 carbon atoms, and the alkylene portion of R2 may contain an ether bond(s); (2) wherein R3 is an alkoxyalkyl group having a total of 3 to 15 carbon atoms, and the alkylene portion of R3 may contain an ether bond(s).
A hair relaxer includes at least one specific mercapto compound such as 2-methoxyethyl 3-mercaptopropionate, 2-mercapto-4-butanolide and 2-mercapto-4-butyrolactam. The hair relaxer can achieve an excellent effect of shaping and relaxing hair over a wide range of pH values from weak acidity to weak alkalinity. In particular, the hair relaxer displays a more superior hair shaping and relaxing performance in a weakly acidic to neutral pH range. Consequently, the hair relaxer can drastically reduce the damage to the hair and skin and can reliably perform straightening, uncurling, curling and other hair processing.

The present invention relates to the field of perfumery. More particularly, it concerns compounds comprising at least one β-thio carbonyl or nitrile moiety capable of liberating an active molecule selected from an α,β-unsaturated ketone, aldehyde or nitrile. The present invention concerns also the use of said compounds in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds. (I) wherein: a) m represents an integer from 1 to 6; b) Pro represents a hydrogen atom or a group susceptible of generating an odoriferous α,β-unsaturated ketone, aldehyde or nitrile and is represented by the formulae (II) or (II′) in which the wavy line indicates the location of the bond between said Pro and the sulfur atom S; and at least one of the Pro groups is of the formula (II) or (II′).
