Abstract
A method for preparing an aqueous fluid personal care composition having an anionic surfactant and a cationic surfactant and/or polymer therein which comprises: PA1 a. contacting at least about 0.2 mole % of the anionic surfactant with a charge neutralizing amount of a cationic surfactant and/or polymer in a reactor and forming an essentially chargeless complex in the reactor which is essentially free of other components of the said composition, and PA1 b. thereafter mixing the preformed complex with the remainder of the composition components.
