Definitions

• the present invention relates to a fabric softening agent for treating textiles in a tumble dryer with a rotating drum.
• fabric softening agents for use in automatic household tumble dryers with a rotating drum have become known.
• Such fabric softening agents often consist of a more or less absorbent substrate impregnated with fabric softeners and optionally auxiliaries and additives, which substrate is generally present as a sheet.
• fabric softening agents of this type are described in DE-A-19 65 470 or in DE-A-30 03 249.
• the impregnated fabrics are placed together with the still damp, freshly washed laundry in the drum of the tumble dryer, where they release a more or less large proportion of their softening active ingredients and auxiliaries under the conditions of laundry drying and through contact with them transferred washed textiles to this.
• a problem with this type of softening of textiles is the often unsatisfactory rate of release of the active substance.
• the reason for this is the fact that the softening active substances naturally have an affinity for their substrates as well as for the textiles to which they are to be transferred. Therefore, when using the impregnated substrates, there is a balance between the loading of the substrates with active substances on the one hand and the loading of the washed textiles these active ingredients on the other hand.
• Known solutions to this problem are, for example, the application of a separating layer between the substrate and the active substance support or the use of dispersing or emulsifying substances when impregnating the substrates with the active substances.
• the materials of the separating layer or the dispersants or emulsifiers in turn either have no or only a slight softening effect, as a result of which the absorption capacity of the substrates for the actual softening active ingredients is reduced. Also for economic reasons, the above proposals are not a satisfactory solution.
• the fabric softening agents intended for use in the tumble dryer are very popular with consumers, especially in the area of private households, because of their easy handling, it is still very popular desirable to reduce or eliminate these disadvantages. It is therefore an object of the present invention to provide a fabric softening agent for treating textiles in a tumble dryer with a rotating drum, the fabric softening agent having an improved active ingredient release rate compared to the known agents for the same purpose.

• the quaternary ammonium compound with two 2-acyloxyalkyl groups and the quaternary ammonium compound with two C10 to C22 alkyl or alkenyl groups are present in the combination in a weight ratio of 1:10 to 2: 1.
• Active ingredient combinations with a softening point of 35 to 60 ° C can be produced within these limits. Since the quaternary ammonium compounds with two C10 to C22 alkyl or alkenyl groups are themselves excellent textile softeners Such active substance combinations represent particularly interesting fabric softeners within the meaning of the present invention.

• the products can additionally contain 0.5 to 5% by weight of dispersing and softening polyglycol ethers.
• Suitable polyglycol ethers are derived from ethylene oxide and have a molecular weight in the range from 200 to 8,000, preferably in the range from 200 to 1,000 and in particular in the range from 400 to 600.
• Other additives having a dispersing action are addition products of ethylene oxide and / or propylene oxide onto fatty alcohols , Fatty amines, fatty acid or sulfonic acid amides, polyethylene glycols or polypropylene glycols, epoxy glycols, alkylenediamine or aliphatic C1 to C8, preferably C3 to C6 alcohols.
• Etheramines are also suitable in the same way Formula R- (C2H4O) n -NR1 R2.
• R is an alkyl or alkenyl radical having 10 to 20 carbon atoms
• n is a number between 2 and 10
• R1 and R2 which may be the same or different, are -C2H4OH or their esters with C10- to C20-monocarboxylic acids or with Sulfosuccinic acid or alkali metal salts of these acids.
• quaternary compounds of the aforementioned ether amines in which a further alkyl group with 1 to 18 carbon atoms is attached to the nitrogen atom with the formation of a positive charge, the positive charge being caused by a negative charge, which is an anion, usually the Chloride or methosulfate anion, carries, is balanced.
