Abstract: A process for producing free flowing spray dried base builder beads comprising inorganic detergent builders. The builder beads comprise alkali metal phosphate, alkali metal silicate and water. The alkali metal phosphate component includes a hydrated and an anhydrous portion. Relatively large amounts of liquid or liquifiable detergent ingredients such as surface active agents etc. can be applied to the base beads after spray drying, without destroying their free flowing properties.

Abstract: A bottled particulate detergent is of certain particle sizes, bulk density and flowability and is contained in a necked bottle in which the neck opening is sufficiently small as to allow ready sealing with screw caps conventionally employed to close bottles while also allowing pouring from the bottle of the particulate detergent of the described characteristics. The bottle also includes a relatively narrow, hollow handle section through which the particulate detergent will flow. Also disclosed is a method of easily filling such bottles with free flowing particulate detergent. In both dispensing and filling operations, due to the characteristic of the detergent composition and the bottle, flow surprisingly like that of a liquid is obtained.
