    摘要： A particulate detergent composition having a bulk density of 700 g/l or less and containing at least 10 wt % (preferably at least 15 wt %) of organic detergent surfactant comprises a base powder composed of at least two granular components. Less than 80% by weight, preferably less than 66% by weight, of the base powder has a compressibility (measured at 20-25° C. and about 40% relative humidity) of 17% or more. Preferably one of the components of the base powder is a granule containing a high level (at least 60 wt %) of anionic surfactant.

    摘要： A detergent block of compressed granular material is provided, said block having a weight of 0.2-10 kg, being substantially free of phoshate builder material, and comprising a granulated builder material, an alkaline agent and a compressing aid. A process is also provided for preparing a block of compressed granular material being substantially free of a phosphate builder and having a weight of 0.2 to 10 kg, said process involving the steps of (i) granulating a non-phosphate builder material, with 0.1-10% by weight based on the weight of the builder of a co-ingredient selected from polycarboxylic polymer solutions, alkali metal silicate solutions, and mixtures thereof;and (ii) compressing a particulate mixture of said granulated builder material and other components of the block, including a compressing aid, in a mould under a pressure of 3-30 kN/cm.sup.2.
