Definitions
- the present invention concerns a process for the preparation of a granular detergent component and also concerns granular detergent components comprising cationic surfactant, in particular hydrolysable cationic surfactants such as choline ester.
- choline esters are readily hydrolised, especially in alkaline conditions. Consequently such powders are unsuitable for use by dry mixing directly into commercial granular detergent compositions which are usually alkaline.
- the object of the invention is to provide a granular detergent components which comprise hydrolysable cationic surfactant and which are stable in commercial detergent compositions.
- this object is achieved by a process for the preparation of a granular detergent component comprising the steps of : (i) drying an aqueous solution of a cationic surfactant to form a powder ; (ii) optionally, densifying the powder ;

- Citric acid was added to aqueous solution of choline ester during its synthesis. Powdered zeolite was then added to the solution and this product was then dried in an oven to remove all the free water and then ground up in a Moulinex coffee grinder. This powder was then compacted in the same manner as in example 3
- the resulting granular detergent component had a reserve alkalinity of 2.3g HCl/100g.
- Polycarboxylic acid in this example was a co-polymer of maleic and acrylic acid with a molecular weight of about
- Citric acid was added to aqueous solution of choline ester during its synthesis. Powdered zeolite and additional powdered citric acid were then added to the solution. This product was then dried in an oven to remove all the free water and then ground up in a Moulinex coffee grinder. This powder was then treated by the same agglomeration process as in example 1.
- the resulting granular detergent component had a reserve alkalinity of 9.1 g HCl/100g.
