A special process for producing a novel and improved coal tar shampoo which makes possible the consistent replication of a preselected pH and makes the shampoo able to retain its clarity, colour and preselected viscosity over an extended period. The process is based on a ratio between fatty acid diethanolamide and cocamidopropylbetain (fatty acid DEA:CAPB) in the interval from 1.3 to 2.6:1, deliberately premixing fatty acid DEA with preservative and aromatic principle without heat before introducing into the master proportion, and neutralising to a pH of approx. 7.6 early in the cycle.
