Summary: | A novel adsorbate (A) comprises a soluble zinc compound (I) of a polycarboxylic acid (PCA), adsorbed on a crystalline alkali metal layered silicate (II). Independent claims are included for the following: (a) the preparation of (I); and (b) detergent or cleansing compositions comprising (by weight) (a) 10-90 (preferably 20-50)% builder and cobuilder, 1-90 (preferably 10-50)% pH regulators, 0.1-20 (preferably 1-20)% bleach, 0-10% surfactants and 0.01-10 (preferably 0.1-10)% (A), (b) 10-90% builder and cobuilder, 1-9% pH regulators, 1-10% bleach, 0.1-50% surfactants and 0.1-10% (A) or (c) 10-90% builder and cobuilder, 1-9% pH regulators, 0.1-50% surfactants and 0.1-10% (A).
Die Erfindung betrifft ein Adsorbat, dadurch gekennzeichnet, dass es eine an kristallines Alkalischichtsilicat adsorbierte lösliche Zink-Verbindung einer Polycarbonsäure enthält und seine Verwendung. |
