Abstract (en)

Washing and cleansing agents in solid or liquid form, containing (a) 1 to 50 wt. % of at least one anionic or cationic tenside, (b) 1 to 90 wt. % of at least one compound from the class of builder salts and sequestering agents and (c) a quantity of other usual constituents of washing and cleansing agents sufficient to make up to 100 wt. %. The component (a) consists wholly or partly of a secondary dialkyl ether sulphate of general formula (I) in which the symbols have the following meaning: M = Na, K, Mg, ammonium or an organic ammonium cation, R<1> = a linear C1-C16 alkyl residue, R<2> = hydrogen or a linear C1-C16 alkyl residue, R<3> = a linear or branched C1-22 alkyl residue, provided that the sum of the C atoms in (R1 + R2) = 1 to 18 and in (R1 + R2 + R3) = 8 to 22, R<4> = hydrogen or CH3 and n is a number between 0 and 15.

Abstract (de)

Es werden Wasch- und Reinigungsmittel in fester oder flüssiger Form mit einem Gehalt an (a) 1 bis 50 Gew.-% mindestens eines anionischen oder kationischen Tensids, (b) 1 bis 90 Gew.-% mindestens einer Verbindung aus der Klasse der Buildersalze und Sequestrierungsmittel und (c) Differenz bis 100 Gew.-% an sonstigen üblichen Wasch- und Reinigungsbestandteilen beschrieben, in denen die Komponente (a) ganz oder teilweise aus einem sekundären Dialkylethersulfat der allgemeinen Formel I besteht: <IMAGE> in der die Symbole die folgende Bedeutung haben: M = Na, K, Mg, Ammonium oder ein organisches Ammonium-Kation, R¹ = linearer C1-C16-Alkylrest, R² = Wasserstoff oder linearer C1-16-Alkylrest, R³ = linearer oder verzweigter C1-22-Alkylrest mit der Maßgabe, daß die Summe der C-Atome in (R1 + R2) = 1 bis 18 und in (R1 + R2 + R3) = 8 bis 22 beträgt, R<4> = Wasserstoff oder CH3 und n = Zahlen von 0 bis 15.
