Definitions

• fabric softeners have so far been used generally in the form of dilute, about 2 to 10% aqueous solutions.
• these diluted solutions have several disadvantages. You can e.g. should not be stored in a cold place, as they will become gel-like after freezing and thawing and can no longer be brought into a homogeneous solution.
• Another disadvantage is the high excess water content of these solutions.
• the invention thus relates to liquid fabric softeners consisting of an aqueous solution or dispersion of compounds of the formula 1.
• R 1 is alkyl having 1 to 4 carbon atoms
• x and y are hydrogen or methyl, where x and y may not be methyl at the same time
• n is an integer from 1 to 10
• p is an integer from 1 to 5
• A is an anion and, if appropriate, further auxiliaries.
• the anion A is preferably a chloride, methosulfate, ethosulfate, methophosphate or ethophosphate ion.
• Methyl is preferred as R 1 .
• the quaternary compounds to be used according to the invention are reacted according to known processes by reacting compounds of the last-mentioned formula with alkylating reagents such as, for example, alkyl halides or alkyl sulfuric acid esters.
• alkylating reagents such as, for example, alkyl halides or alkyl sulfuric acid esters.
• the quaternary compounds are obtained depending on the fatty acid used as a highly viscous liquid to solid substances.
• the liquid fabric softeners according to the invention When preparing the liquid fabric softeners according to the invention, they will soften cationic ones the compounds expediently used in the form of their concentrated solutions in lower alcohols, preferably isopropanol or in a mixture of these alcohols with water.
• the fabric softening agents according to the invention contain a certain amount of such lower alcohols (approx. 5-30% by weight).
• Another constituent of the fabric softener according to the invention can be customary nonionic dispersants or emulsifiers based on oxalkylates, which contribute to the fact that the fabric softener is readily dispersible in cold water.
• Suitable nonionic dispersants are e.g. Reaction products of about 2-12 moles of ethylene oxide each with an alkylphenol such as e.g.
• Xylenol but also with an alkylphenol with a long alkyl radical of 8-10 carbon atoms or with a fatty alcohol with 8 to 15 carbon atoms, in particular reaction products of about 5 to 8 mol of EO with 1 mol of alkylphenol or 1 mol of an 8 to 15 C-containing fatty alcohol or a mixture of such fatty alcohols.
• the amount of these nonionic compounds is 3 to 10% by weight in the case of weakly concentrated fabric softeners with a content of the compounds of the formula 1 of approximately 10 to 30% by weight.
• Highly concentrated fabric softeners with a content of the compounds of formula 1 of approximately 30 to 70% by weight preferably contain 5 to 20% by weight of the nonionic dispersant.
• With the diluted, commercially available fabric softeners it is not necessary to add such dispersants.
• Such diluted fabric softeners contain the quaternary ammonium compound in a concentration of 2 to 10%.
• the more highly concentrated fabric softeners also contain 5 to 30% by weight, preferably an ethylene glycol, propylene glycol, polyethylene glycol, polypropylene glycol and the C 1 -C 4 -alkyl ethers of these compounds. It goes without saying that only compounds of this product group that are liquid are suitable. These compounds have a solubilizing effect in the fabric softeners according to the invention.
• the fabric softening agents according to the invention can be produced by simply mixing the components or their concentrated solutions. If necessary, perfume, dye, optical brighteners or other auxiliaries can also be added. To set the desired final concentration, it may be diluted with the necessary amount of water. The amounts of the individual components are chosen within the specified limits so that the finished agent, including any additional amounts of water, perfume and colorants, is 100% by weight.
• the amount of the fabric softener according to the invention is 80 to 150 ml, 30 to 70 ml or 10 to 20 ml for a fabric softener containing a compound of the formula 1 of 2 to 10% by weight. -%, 10 to 30 wt .-% and 30 to 70 wt .-%.
• the fabric softening agents according to the invention which have good softening properties, can be dispersed well in cold water without causing disruptive gel formation. It is advantageous here that these concentrates can be fed directly into household machines with suitable metering devices. This good solubility also allows the concentrates according to the invention to be diluted shortly before they are put into the washing machine, so that the w heavy duty detergent can also be traded in concentrated form and not just as dilute aqueous solutions. This eliminates the need to transport large, ultimately superfluous amounts of water at all stages of the trade.
