The present invention relates to a process for preparing a solid free-flowing particulate laundry detergent composition, wherein the process includes the steps of: (a) forming a mixture by contacting: (i) molten fatty acid; (ii) liquid alkaline ingredient, and (iii) non-ionic surfactant, to obtain a mixture, wherein the mixture includes: (i) partially neutralized fatty acid component; (ii) non-ionic surfactant; and (iii) water, wherein the molar ratio of fatty acid to liquid alkaline ingredient contacted together in step (a) is above 1:1; (b) contacting the mixture obtained in step (a) to a detergent powder to form a solid free-flowing particulate laundry detergent composition, wherein in step (b) the mixture is contacted to the detergent powder by spraying the mixture at a temperature of greater than 50° C. onto the detergent powder, wherein the detergent powder includes a detergent ingredient.

Process for making a laundry detergent composition

A device for dosing a detergent ingredient into the drum of an automatic washing machine which can include a reservoir, a one-way valve, an inlet, and a dosing manifold.

Device for dosing a detergent ingredient into the drum of an automatic washing machine

A solid free-flowing particulate laundry detergent composition including: (a) from 0.1 wt % to 5 wt % hueing agent particle comprising: (i) from 2 wt % to 10 wt % hueing agent; and (ii) from 60 wt % to 98 wt % clay; and (b) from 0.5 wt % to 20 wt % ethoxylated alkyl sulphate particle including: (i) from 40 wt % to 60 wt % partially ethoxylated alkyl sulphate anionic detersive surfactant; (ii) from 20 wt % to 50 wt % salt; and (iii) from 10 wt % to 30 wt % silica.

Solid free-flowing particulate laundry detergent composition

A solid free-flowing particulate laundry detergent composition including: (a) from 0.1 wt % to 5 wt % polymer particle comprising: (i) from 70 wt % to 90 wt % co-polymer and (ii) from 10 wt % to 30 wt % salt; and (b) from 35 wt % to 80 wt % spray-dried particle including: (i) from 8 wt % to 24 wt % alkyl benzene sulphonate anionic detersive surfactant; (ii) from 5 w % to 18 wt % silicate salt; (iii) from 0 wt % to 10 wt % sodium carbonate; and (iv) from 0 wt % to 5 wt % carboxylate polymer.

A solid free-flowing particulate laundry detergent composition comprising: (a) from 0.1 wt % to 5 wt % hueing agent particle comprising: (i) from 2 wt % to 10 wt % hueing agent, wherein the hueing agent has the following structure: wherein:

A solid free-flowing particulate laundry detergent composition including: (a) from 0.5 wt % to 20 wt % ethoxylated alkyl sulphate particle including: (i) from 40 wt % to 60 wt % partially ethoxylated alkyl sulphate anionic detersive surfactant; (ii) from 20 wt % to 50 wt % salt; and (iii) from 10 wt % to 30 wt % silica; and (b) from 0.01 wt % to 2 wt % perfume.

A solid free-flowing particulate laundry detergent composition comprising: (a) from 0.1 wt % to 5 wt % hueing agent particle comprising: (i) from 2 wt % to 10 wt % hueing agent, wherein the hueing agent has the following structure: 

Process for manufacturing particles, the process comprising the steps of: feeding a feed material comprising from 40 to 70% of alkyl sulfate surfactant(s) and from 12 to 30% of water to an extruder comprising an extrusion head, mechanically working and cooling the feed material within the extruder to form an extrudable mass, extruding the extrudable mass through the extrusion head to form strand(s), and forming particles from the strand(s), wherein the alkyl sulfate surfactant(s) comprise at least 50% of C-Calkyl sulfate surfactant(s).

Process for manufacturing extruded alkyl sulfate particles

A detergent additive extrudate containing from about 0.5% to about 20% an alkyl benzene sulphonate, from about 0.5% to about 15% a water soluble carboxylate-containing polymer, from about 20% to about 80% water soluble inorganic salt and a moisture level of 2% to 10%; process for making the detergent additive extrudate and granular laundry detergent containing the same. The detergent additive extrudates have an improved physical stability, dissolution property and ease of process property.
