  • Patent number: 4168144
    Abstract: This specification is concerned with a hair colorant composition in which the dyestuffs are basic dyes. The composition is made high foaming by the incorporation of an anionic:cationic detergent complex. A typical example of such a composition has the following formulation:______________________________________ % by weight ______________________________________ Basic dyestuff 2.8 Potassium laurate 2.3 Lauryl trimethyl ammonium 5.4 bromide Targitol NP 35 (a nonionic 6.0 surfactant) Isopropanol 10.0 Thickener 3.2 Water to 100 ______________________________________Such a composition when formulated as described has been found to give high foaming with good intensity dyeing even in the darker shades, even dyeing and good coverage of hair containing as much as 15 to 25% grey.
