MICRO-POROUS CRYSTALLINE MATERIAL, PROCESS OF ITS PREPARATION AND USE IN DETERGENT COMPOSITIONS

摘要

A microporous crystalline material named zeolite A-LSX having, in its anhydrous form,an oxides molar composition corresponding to formula (I): $in\; which:\; M\; and\; M\text{'},\; identical\; or\; different,\; represent\; a\; cation\; of\; an\; alkaline\; or\; alkaline\; earth\; metal\; of\; valency\; n;\; z\; is\; a\; number\; between\; 2.1\; and\; 2.6,\; extremes\; included.\; Said\; microporous\; crystalline\; material\; can\; be\; used\; as\; a\; builder\; in\; detergent\; systems.$
