| Abstract | ||||
| A new concept of colouring human hair fibres by coating them with a dyestuff coupled to a carrier (a positively charged polymer) is introduced and evaluated. The complex dyestuff-charged polymer is synthesised and applied on hair under normal conditions. The polymer-carrier, used in this work, is the branched poly(ethylene imine) (PEI), whose primary amine groups were modified at different ratio with quaternary ammonium groups and synthesised reactive dyestuff to give polymer-dye conjugates. The adsorption of charged substances from external aqueous media to hair has been investigated under neutral pH. The colour covers evenly the hair fibre and proves to be fast to shampooing, although the polymer-dyestuff complex is confined to cuticle region only. Compared to reference, the coating of hair yields higher colour intensity than the infiltration of the fibre. | ||||
