DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to detergent mixtures containing esterquats and soil-repelling polymers, to formulations containing these mixtures and to the use of the mixtures for the production of surface-active formulations.
2. Discussion of Related Art
Depending on their structure, cationic surfactants have the ability to attach themselves to negatively charged surfaces, for example textile fibers or hair strands. In doing so, they reduce electrostatic charging and impart a pleasant soft feel. This effect is utilized in practice, for example in the formulation of fabric softeners or hair treatment formulations.
Whereas, until a few years ago, quaternary ammonium compounds, for example dimethyl distearyl ammonium chloride, were almost exclusively used as cationic ingredients, quaternized fatty acid triethanolamine ester salts, so-called "esterquats", which combine improved ecotoxicological compatibility with a comparable softening effect, are now being used to an increasing extent in modern fabric softeners. Reviews of this subject have been published, for example, by O. Ponsati in C.R. CED Congress, Barcelona, 167 (1992) and by R. Puchta in C.R. CED Congress, Sitges, 59 (1993).
Nevertheless, there is a market need for fabric softeners which provide fabrics with improved softness or with which the required softness can be obtained with a smaller quantity of softener.
It is also known that oily soil is very much easier to remove from hydrophilic fabrics, for example of cotton, than from hydrophobic polyester fabrics which is a result of the greater affinity of cotton for water and surfactants. This difference in behavior is explained by the chemical structure of the fibers. Polyester fibers are copolymers of terephthalic acid and ethylene glycol which contain only very few free hydroxyl or carboxyl groups onto which water can be added. By contrast, cotton consists of a cellulose material which, conversely, has a large number of hydrophilic groups. Accordingly, there is a further need on the part of the consumer for new fabric softeners which soften polyester fabrics in particular in such a way that their tendency towards soiling is reduced or oil-containing soils in particular can be readily removed in the subsequent washing process.
It would be appropriate in this connection to mention U.S. Pat. No. 3,712,873 from which the use of polyester terpolymers with a molecular weight of 1,000 to 100,000 in conjunction with quaternary ammonium compounds as fabric treatment compositions is known. The compositions are applied to the fabrics by spraying or padding and are intended to improve the soil-repelling properties of the fabrics. As comparison tests have shown, a slight improvement in the removability of oil-containing soils by washing is indeed obtained, but unfortunately softness and hydrophilicity tend to be adversely affected.
Accordingly, the problem addressed by the present invention was to provide new fabric softeners which would not be attended by any of the disadvantages mentioned above.
DESCRIPTION OF THE INVENTION
The present invention relates to detergent mixtures containing quaternary ammonium compounds (QUATS) and soil-repelling polymers containing ethylene terephthalate and/or polyethylene glycol terephthalate groups which are characterized in that they contain as QUATS quaternized fatty acid ester salts (esterquats) corresponding to formulae (I), (II) or (III): ##STR2## in which R.sup.1 CO is an acyl radical containing 6 to 22 carbon atoms, R.sup.2 and R.sup.3 independently of one another represent hydrogen or have the same meaning as R.sup.1 CO, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 independently of one another represent an alkyl group containing 1 to 4 carbon atoms or a (CH.sub.2 CH.sub.2 O).sub.q H group, R.sup.5 is an alkyl radical containing 1 to 4 carbon atoms, m, n and p together are 0 or numbers of 1 to 12, q is a number of 1 to 12 and X stands for halide, alkyl sulfate or alkyl phosphate.
