Abstract
A nitrophenylenediamine dye composition includes a long chain alkyl (8 to 18 carbon chain length) sulfate detergent, such as sodium lauryl sulfate or ammonium lauryl sulfate together with a sultaine (sulfobetaine) surfactant in a ratio of sulfate/sultaine in the range of 1:1 to 10:1, and particularly in the range of 6:1 to 9:1 to achieve unexpectedly increased deposition of specific nitrophenylenediamine dyes onto human hair.
