Parçacikli bir deterjan bilesimine dahil etmek için uygun bir granül bilesimi olup, sunlari ihtiva etmektedir: (a) renklendirilmis veya floresan bir içerik madde, örnegin çinko veya alüminyum ftalosiyanin sülfonat gibi bir foto-agartici; (b) renklendirilmis veya floresan içerik madde için bir tasima malzemesi, ki bu bir alfa-hidroksi organik asit, tercihen sitrik asittir; (c) suda çözülebilen veya suda dagitilabilen bir bariyer malzemesi, tercihen suda çözülebilen bir nisasta veya polivinil alkol; ve (d) inorganik bir akis degistiricisi, örnegin sili ve/veya kaolin. Granüllü malzeme parçacikli deterjan bilesimlerine eklenebilmektedir ve yikanan kumaslar üzerinde leke birakma egilimi azdir. A granular composition suitable for incorporation into a particulate detergent composition comprises: (a) a coloured or fluorescent ingredient, for example, a photobleach such as zinc or aluminium phthalocyanine sulphonate; (b) a carrier material for the coloured or fluorescent ingredient which is an alpha -hydroxy organic acid, preferably citric acid; (c) a water-soluble or water-dispersible barrier material, preferably a water-soluble starch or polyvinyl alcohol; and (d) an inorganic flow modifier, for example, silica and/or china clay. Preferably, the coloured or fluorescent ingredient is dispersed onto the alpha -hydroxyacid which is mixed with part or all of the inorganic flow modifier and the whole treated with the barrier material, then granulated with any remaining inorganic flow modifier. The granular material can be incorporated into particulate detergent compositions, where it shows a reduced tendency to leave stains on washed fabrics.
