Shampoo Production Process

Shampoo is a low-to-medium viscosity surfactant system comprising primary surfactants (e.g., sodium lauryl ether sulphate), co-surfactants, conditioning agents, thickeners, and functional additives such as anti-dandruff agents or pearlising concentrates. The primary challenge is to dissolve and hydrate thickening polymers (often sodium chloride or cellulose ethers) without forming lumps, while incorporating pearlising agents and silicone emulsions uniformly.

Role of High Shear Mixing

PVA Systems process units handle shampoo manufacture by first preparing the surfactant base at 40–50 °C under gentle agitation. The high shear homogenizer is then engaged to disperse thickeners, pearlising wax, and actives without excessive foam generation — aided by vacuum processing which suppresses air entrainment. The result is a clear or pearlescent product with consistent viscosity (typically 3 000–8 000 cP) and homogeneous distribution of suspended particulates. Batch processing times are reduced by up to 50 % compared to traditional propeller-and-paddle methods.
