A process for the manufacture of a structured liquid detergent composition comprising: a) at least 0.00005%wt, preferably 0.05-10%wt, of a disperse-phase benefit agent, b) 0.025- 0.2%wt, of micro-fibrous cellulose, c) less than l%vol incorporated air, and, d) at least 5%wt of anionic surfactant and 25 to 55%wt surfactant, the process comprising the steps of (i) preparation of a micro-fibrous cellulose premix, at a concentration of 0.1-2.5%wt, preferably 0.1- 2%wt, using high shear mixing, preferably under conditions which generate a liquid velocity of greater than 3 m.s -1 , (ii) separate preparation of an aqueous surfactant mix comprising less than l%wt of incorporated air, and the bulk of the water in the composition, (iii) combination of the micro-fibrous cellulose premix and the surfactant mix using high shear mixing, preferably under conditions which generate a liquid velocity of greater than 3 m.s -1 and maintaining the air content below l%vol at least during gel formation. |
