BRIEF SUMMARY
This application is a 371 of PCT/EP94/03354, filed Oct. 12, 1994.


BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to the use of endgroup-capped fatty amide alkoxylates of the general formula I compositions, as surface-active substances for industrial applications in electroplating, in the photographic industry, in petroleum production, in the pharmaceutical industry, in plant feeding and in crop protection formulations, and as surface-active substances in the production of emulsions and pigment and plastic dispersions.
The invention furthermore relates to detergents, cleaners and body care compositions which contain the compounds I. Since some of the compounds I are novel substances, the invention also relates to these novel substances. The invention furthermore relates to a process for preparing these novel substances.
2. Discussion of the Background
Washing and cleaning processes in industry, commercial operations and domestically nowadays increasingly demand surface-active substances which are distinguished in particular by good alkali stability, a large reduction in surface tension and good wetting and foaming capacity, and for mechanical cleaning processes there is a need in particular for low foaming and efficient foam suppression. Furthermore, these surface-active substances ought to be substantially biodegradable and not entail any potential health risk.
DE-A 24 23 893 (1) describes a deicing and antiicing composition for aircraft which contains an addition of a water-dispersible compound of the formula .alpha. radical, X is, inter alia, the group --CO--NH--, n is a number from 1 to 30 and Y is, inter alia, a C.sub.1 -C.sub.20 -alkyl group. Another possible addition to this composition is a water-insoluble compound of the formula .beta. which may contain a hydroxyl group, A is, inter alia, the group --CO--NH--, R.sup.1 is hydrogen or methyl, m is a number from 1 to 3 and B is, inter alia, a C.sub.1 -C.sub.5 -alkyl radical.
U.S. Pat. No. 3,746,644 (2) discloses oleic acid derivatives of the formula --O--CH.sub.2 CH.sub.3 --O--CH.sub.2 CH.sub.2 --O--CH.sub.2 CH.sub.3. and are stable to bases.
EP-B 211 493 (3) relates to a liquid cleaner composition which comprises a mixture of an ionic surfactant and a polyalkoxy nonionic surfactant of the general formula RVEW. In this, R is an (ar)aliphatic hydrocarbon moiety, V is, inter alia, the group --CO--NH--, E is polyethoxy and/or polypropoxy (no general statement is made about the degree of alkoxylation, but it is 14 or 20 in the examples) and W is a nonionic endgroup, eg. OH or CH.sub.3.


SUMMARY OF THE INVENTION

Said prior art fatty amide alkoxylates are, however, still in need of improvement in respect of their washing and cleaning properties. It is an object of the present invention to provide surfactants or emulsifiers for use in detergents, cleaners and body care compositions with an improved profile of properties.
We have found that this object is achieved by using the endgroup-capped fatty amide alkoxylates I defined at the outset for this purpose.


DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The radical R.sup.1 is C.sub.5 -C.sub.21 -alkyl or -alkenyl, preferably C.sub.7 -C.sub.19 -alkyl or -alkenyl, in particular C.sub.9 -C.sub.17 -alkyl or -alkenyl. R.sup.1 is preferably the residue of a long-chain carboxylic acid, in particular of a naturally occurring fatty acid such as lauric acid, myristic acid, palmitic acid, stearic acid or oleic acid or of a carboxylic acid which has been synthesized by the oxo or Ziegler method. Mixtures of various R.sup.1 radicals may also occur.
The radical R.sup.2 is C.sub.1 -C.sub.4 -alkyl such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl or tert-butyl, preferably methyl, ethyl and n-butyl.
The variable A is, in particular, 1,2-alkylene groups, especially 1,2-ethylene, but also 1,2-propylene, 1,2-butylene or 2,3-butylene.
The degree of alkoxylation x has a value from 1 to 6, preferably from 2.2 to 4.5, in particular from 2.5 to 4, where x can be a
