The invention relates to aqueous compositions for hair treatment, comprising polyorganosiloxanes A) or organic compounds B) having certain functional groups, in particular aldehyde and unsaturated dicarboxylic acid moieties, hair treatment or hair care compositions comprising the aqueous compositions, a process for the treatment of hair which comprises the steps of providing the aqueous compositions and applying said aqueous compositions to the hair, and the use of the aqueous compositions for the treatment of hair.
Surfactants capable of releasing and/or dissolving polymers to form water-soluble or water-dispersible polymer solutions are disclosed. In addition, polymer compositions containing a water-in-oil emulsion comprising the surfactant are provided and can be used, for example, in methods of dissolving a polymer. Also disclosed are detergent compositions and methods of cleaning articles and/or membranes using the surfactants herein. These surfactants and polymer compositions can be used in various industries including for water clarification, papermaking, sewage and industrial water treatment, drilling mud stabilizers, and enhanced oil recovery.

Formation of borane complexes of N, N-dimethylbenzylamine, N,N-dimethyl(1-naphthyl)methylamine, N,N-dimethyl(2-naphthyl)methylamine, N-methyltetrahydroisoquinoline and N-methylisoindoline facilitates regioselective metallation of these systems using BuLi, giving intermediate benzylic anions which react with a range of electrophiles to give products in good yield.
