Abstract
An aqueous single phase composition, particularly for use in the treatment of keratinous fibres, comprises a cationic polymer or mixtures thereof, an anionic monomer or mixtures thereof, and a solubilizing agent chosen from amphoteric detergent active compounds, inorganic electrolytes and mixtures thereof. The composition should have an anionic to cationic charge ratio of from 0.2 to 1.0. When the monomer is an anionic dye, the composition can be employed in the dyeing of hair.
