A process for producing a granular detergent composition containing a surface active agent, a zeolite, an alkali metal silicate, and other detergent builder is described. This granular detergent composition is produced by either (1)

Process for producing granular detergent composition

A granular detergent composition is described containing an .alpha.-sulfo fatty acid ester salt and having good granular or powder properties, without containing any phosphate, and also having a less decomposable property of an .alpha.-sulfo fatty acid ester salt contained therein. This granular detergent composition comprises

Granular detergent composition

Non-phosphate laundry detergents in granular form having good detergency, good granular strength and little tendency to deposit zeolite on fabrics are obtained by using a combination of olefin sulfonate, linear alkylbenzene sulfonate, sodium silicate and type A zeolite detergent builder.

Granular detergent containing zeolite, silicate, LAS and olefin sulfonate

A granular detergent composition comprising .alpha.-olefin sulfonate and poly(oxyethylene)-poly(oxypropylene) alkyl ether at the weight ratio in the range of from 4:1 to 1:1 and further comprising an inorganic builder possesses satisfactory powder properties and is sufficiently easy to rinse out after being used for washing.

Free-flowing granular detergent compositions containing olefin sulfonates

A granular detergent composition contains substantially no phosphate builder component but has excellent powdery characteristics. The granular detergent composition comprises (a) 20 to 35 wt.% of a surfactant comprising an .alpha.-olefinsulfonate and an alkyl ether sulfate at a ratio of the .alpha.-olefinsulfonate to the alkyl ether sulfate of 1 : 1 to 5 : 1 by weight; and (b) 40 to 70 wt.% of a builder comprising a carbonate and a silicate at a ratio of the carbonate to the silicate of 2 : 1 to 5 : 1 by weight.
