Definitions
- the present invention is directed to methods of making granular detergent compositions containing perfume.
- Granular laundry detergent compositions are well known.
- Granular laundry detergent compositions comprise one or more surfactants which can provide a good fabric-cleaning performance.
- Genearlly, granular laundry detergent compositions can be prepared by using different processes including spray-drying and agglomerate.
- Spray-drying is the standard method for manufacturing laundry detergent base powder.
- detergent ingredients are mixed together to form an aqueous detergent slurry in a mixer, such as a crutcher mixer. This slurry is then transferred along a pipe through a first low pressure pump and then through a second high pressure pump to a spray nozzle, and the slurry is sprayed into a spray-drying tower, and spray-dried to form a spray-dried powder.
- a suitable agglomeration process comprises the step of contacting a detersive ingredient, such as a detersive surfactant, e.g. linear alkyl benzene sulphonate (LAS) and/or alkyl alkoxylated sulphate, with an inorganic material, such as sodium carbonate and/or silica, in a mixer.
- a detersive ingredient such as a detersive surfactant, e.g. linear alkyl benzene sulphonate (LAS) and/or alkyl alkoxylated sulphate

- perfume is generally added by spraying onto base detergent particles, such as spray-dried base detergent particles and/or agglomerated base detergent particles.
- base detergent particles such as spray-dried base detergent particles and/or agglomerated base detergent particles.
- this spray-on step is carried out in a tumbling drum mixer.
- the inventors of the present invention notice that the spray-on perfume is not sufficiently stable due to various causes, e.g. evaporation and/or degradation during the making and storage.
- one of the solutions is to increase perfume level so as to secure superiority of the final products to consumers, which apparently results in a higher cost.
- the inventors of the present invention have surprisingly found that if perfume is pre-mixed with a liquid protective agent before spraying onto the detergent particles, the stability is significantly improved. As such, the total amount of perfume needed for the making of granular detergent products can be reduced, resulting in cost saving.
- the present invention addresses the aforementioned needs by providing the following method of making a granular detergent composition.
