Description

BACKGROUND OF THE INVENTION Active (LAS) products have quaternary products

Detergent compositions used for cleaning purposes, such as textile washing, typically contain a plurality of surfactants.

The ability of surfactants to clean many types of dirt and stains on textiles present in a typical load of laundry is of great importance in evaluating detergency performance. However, the relative ability of the individual surfactants to meet various performance criteria depends, among other things, on the presence of other surfactants or de1 (co-de1).

Recent trends in the partial or total replacement of linear alkyl benzene sulphonate surfactants have required detergent manufacturers to reassess their various and surface ammonium salts are the grease removal efficiencies in Nil-LAS compositions.

There is a need for efficacy and flexibility in obtainable surfactant systems that provide optimum detergency performance equal to that of LAS-containing detergents.

The above-mentioned requirement satisfies the surfactant system with the active ingredients. For example, less effective in enhancing anionic surfactants selected from the group consisting of alkoxylated alkyl sulfates and alkyl sulfates, said surfactant system further comprising an additional surfactant (co-agent) selected from the group of primary or tertiary amines.

It has surprisingly been found that detergent compositions comprising said surfactant system have a cleaning performance equivalent to that of a LAS-containing detergent.

In addition, it has been found that a small amount of certain primary or secondary amines of the present invention provides an efficient and compatible suds suppressor system. This additional advantage makes it possible to use amines in a dual function, eg as surfactants and suds suppressors, thereby facilitating the formulation of concentrated liquid detergents.

Liquid detergent formulations formulated with said surfactant system are very useful when liquid detergent compositions are in direct contact with fabrics, such as in prewash.

Amines in liquid detergent compositions have been described. EP 160 762, EP 137 615 and EP 137 616 disclose liquid detergents containing cyclohexylamine.
