ABSTRACT OF THE DISCLOSURE A novel process for producing a new and improved coal tar shampoo which permits consistent replication at a preselected pH and is capable of retaining its clarity, color and preselected viscosity for an extended time period. The process is predicated upon a fatty acid diethanolamide to cocamidopropyl betaine (Fatty Acid DEA:CAPB) ratio of the range of 1.3-2.6:1, deliberate preblending of Fatty Acid DEA with preservative and fragrance without heat before introduction into the master batch, and early cycle neutralization to a pH of circa 7.6.
