Abstract

A structured detergent particle with mid-level surfactant activity, which contains 35-50 wt% of a C 10-C 20 linear alkyl benzene sulphonate, 0.5-8 wt% of a hydrophilic silica, 40-60 wt% of a water-soluble alkaline metal carbonate, 0-5 wt% of a phosphate builder. Such structured detergent particles are free flowing with little or no moisture content, and are formed by a dry neutralization process without any subsequent drying.

Description

technical field

[0001] The present invention relates to granular detergent compositions. In particular, it relates to granular detergent compositions comprising free-flowing structured detergent particles having a moderate level of surfactant activity (e.g., 35% to 50% by weight) and relatively high Low water content (eg, 0% to 3% by weight), it can be easily formed by dry neutralization method without any subsequent drying. Background technique

[0002] Anionic surfactants comprising linear alkylbenzene sulfonates ("LAS") are among the most commonly used cleaning actives in powder detergent formulations. Detergent particles comprising LAS can be readily formed by a variety of different agglomeration processes.

[0003] For example, a liquid LAS acid precursor (i.e., linear alkylbenzene sulfonic acid and commonly referred to as "HLAS") can be mixed with an aqueous solution of sodium hydroxide (i.e., caustic) to form a substantially neutralized LAS paste , which are then m...
