Abstract

Patente de Invenção:<B>"BUILDER DE CARBONATO DE CáLCIO CRISTALINO SELECIONADO PARA USO EM, COMPOSIçõES DETERGENTES"<D>. Uma composição detergente contendo um builder de detergente barato na forma de um carbonato de cálcio cristalino selecionado é provida. Especificamente, o carbonato de cálcio cristalino tem uma estrutura de cristal substancialmente romboédrica com índices cristalográficos {1,0-1,1}. O carbonato de cálcio cristalino pode ser calcita que foi especialmente modificada para uma estrutura de cristal romboédrica com índices {1,1,-1,1}. O carboneto de cálcio cristalino da presente invenção é extremamente barato porque pode ser facilmente fornado a partir de calcita de ocorrência natural barata, e ele desempenha bem mesmo quando usado em grande tamanhos médios de partículas.Invention Patent: <B> "CRYSTALLINE CALCIUM CARBONATE BUILDER SELECTED FOR USE IN, DETERGENT COMPOSITIONS" <D>. A detergent composition containing an inexpensive detergent builder in the form of a selected crystalline calcium carbonate is provided. Specifically, crystalline calcium carbonate has a substantially rhombohedral crystal structure with {1.0-1.1} crystallographic indices. Crystalline calcium carbonate can be calcite which has been specially modified for a rhombohedral crystal structure with indices {1,1, -1,1}. The crystalline calcium carbide of the present invention is extremely inexpensive because it can be easily supplied from inexpensive naturally occurring calcite, and it performs well even when used on large medium particle sizes.
