DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to detergent mixtures containing alkyl and/or alkenyl oligoglycosides, selected fatty alcohol polyglycol ethers and, optionally, amphoteric or zwitterionic surfactants and also water, to manual dishwashing detergents containing these mixtures and to the use of the mixtures for the production of surface-active preparations.
2. Statement of Related Art
Alkyl oligoglycosides and, in particular, alkyl oligoglucosides are nonionic surfactants which, by virtue of their native raw material base (fatty alcohol and sugar), are acquiring increasing significance and are used, for example, in manual dishwashing detergents or cosmetic products results, there is still a need for detergent mixtures based on alkyl glucosides of which the performance level synergistically exceeds that of the individual components.
There has hitherto been no shortage of attempts to develop detergent mixtures based on alkyl oligoglucosides which have advantageous properties.
EP-B-0 070 074, EP-B-0 070 075, EP-B-0 070 076 and BP-B-0 070 077 (Procter & Gamble), for example, describe high-foaming combinations of alkyl oligoglucosides with anionic surfactants, such as soaps, alkylbenzene sulfonates, fatty alcohol sulfates, conventional fatty alcohol ether sulfates, .alpha.-olefin sulfonates and alkane sulfonates and, optionally, betaine surfactants.
According to the teaching of EP-B1 0 075 996 (Procter & Gamble), aqueous cleaning preparations may contain alkyl polyglucosides, fatty alcohol polyglycol ethers and detergent builders. A similar composition is also claimed in DE-A1 40 39 223 (Huls).
In addition, DE-A1 35 34 082 proposes skin-friendly dishwashing detergents containing a combination of anionic sulfate or sulfonate surfactants, alkyl oligoglucosides and fatty acid alkanolamides.
However, where these known detergent mixtures are used in surface-active preparations, reductions in performance and ecotoxicological compatibility have hitherto had to be accepted in some cases.
Accordingly, the problem addressed by the present invention was to develop detergent mixtures based on alkyl and/or alkenyl oligoglycosides which would have further improved properties.
Above all, a particular concern was to provide concentrates which concentrated form and
DESCRIPTION OF THE INVENTION
The present invention relates to detergent mixtures containing atoms, G is a sugar unit containing 5 or 6 carbon atoms and p is a number of 1 to 10; ##STR2## in which R.sup.2 represents alkyl radicals containing 6 to 14 carbon atoms, n is a number of 0.5 to 2 and m is a number of 2 to 10 and, optionally,
It has surprisingly been found that the detergent mixtures according to the invention have a washing, dishwashing, foaming and cleaning power and skin-cosmetic compatibility which exceed those of the individual constituents through synergistic enhancement. At the same time, the mixtures are liquid or flowable, even in highly concentrated form, and have cold cloud points below -3.degree. C. Although mixtures of alkyl oligoglucosides, fatty alcohol polyglycol ethers and betaines are also known in principle from the prior art for the claimed application, the detergent mixtures according to the invention still cannot be regarded as obvious because the claimed combination effect of particular skin-cosmetic compatibility, good cleaning performance and advantageous rheology can only be found in a very small number of the broad range of commercially available fatty alcohol polyglycol ethers; the choice made in accordance with the invention is documented by Comparison Examples.
Alkyl and/or alkenyl oligoglycosides (APG) are known substances which may be obtained by the relevant methods of preparative organic chemistry. EP-A1-0 301 298 and WO 90/3977 are cited as representative of the extensive literature available on the subject.
The alkyl and/or alkenyl oligoglycosides may be derived from aldoses or ketoses containing 5 or 6 carbon atoms, preferably from glucose. Accordingly, the preferred alkyl and/o
