• the already known stain removing agents increase in an undesirable manner the tendency to develop foam in the washing liquor so that this may result in a foaming over of the liquor, when the laundry is done in drum washers, even if socalled foam-arresting detergents are used.
• An object of the present invention is to develop a spotremoving agent, which does not possess the indicated shortcomings and which, due to its low-viscosity, can be applied to the textile fabric easily and without additional rubbing.
• Another object of the invention is the obtention of liquid, low-foaming spot-removing agents consisting of agents consisting of A. from 25 percent to 45 percent by weight of a water-soluble compound of the formula wherein R represents a straight'chained hydrocarbon having from 16 to 24 carbon atoms selected from the group consisting of alkyl, alkenyl and alkadienyl, and x and y represent integers of from 20 to 40,
• B from 25 percent to 45 percent by weight of a substantially water-insoluble compound of the formula wherein R represents a straight chained hydrocarbon having from 14 to 22 carbon atoms selected from the group consisting of alkyl, alkenyl and alkadienyl, and 2 represents an integer of from one to eight,
• the invention relates to a liquid, low-foaming spot-removing product, characterized by its content of:
• R represents a straight, saturated or unsaturated alkyl radical containing from 16 to 24 carbon atoms, and x and y are integers of 20 to 40,
• R is a straight, saturated or unsaturated alkyl radical having from 14 to 22 carbon atoms, and 2 represents an integer of one to eight,
• organic solvents in such an amount all together not exceeding 50 percent by weight, so that the viscosity of the product does not amount to more than 500 c? at a temperature of 20 C.
• alkoxylated product of formula A it is preferable to employ a straight chain alkanol having from l8 to 22 carbon atoms which is alkoxylated first with from 25 to 35 mols of ethylene oxide and thereafter with from 25 to 35 mols of propylene oxide.
• a straight chain alkanol having from l8 to 22 carbon atoms which is alkoxylated first with from 25 to 35 mols of ethylene oxide and thereafter with from 25 to 35 mols of propylene oxide.
• Customarily mixed saturated fatty alcohols are employed although.
• purified alcohols may likewise be utilized as well as unsaturated alcohols such as alkenols and alkadienols.
• similar alcohols can be employed.
• alkylene oxide condensates are employed, wherein the alkyl radical R contains from 18 to 22 carbon atoms, and x and y represent integers of 25 to 35, and wherein the number 2 is selected so that on an average for every four carbon atoms in the alkyl chain of R not more than one glycol ether group is employed. If this ratio is substantially exceeded in direction toward a higher ethoxylation degree, the cleaning effectiveness of the agents will decline.
• the organic solvents to be employed should have a boiling pointnot below 50 C. and not exceeding 350 C. For the usual handling of the agents, these organic solvents should be essentially physiologically harmless without developing any annoying odor.
• Suitable for this purpose are alcohols, such as alkanols, for example, ethanol, propanol, isopropanol, ethylhexanol, etc.; phenylalkanols, for example, methylphenylcarbinol; ether alcohols, such as diethyleneglycol, the monomethyl or monoethyl ether of ethylene or propylene glycol or glycerine diethyl ether; amino alcohols, such as mono-, dior triethanolamines.
• Ketones and ethers are also suitable, such as acetone, methylethylketone and cyclohexanone; dipropylether, diisopropylether and diisogutylether.
• carboxylic acid esters such as ethyl acetate, propyl acetate or ethylene glycol diacetate; aliphatic and aromatic hydrocarbons such as benzene, methylcyclohexane, tetraline or decaline; as well as chlorinated hydrocarbons, such as trichloroethylene or carbon tetrachloride.
• mixtures of the solvents mentioned are used to advantage.
• the portion of the organic solvents should not exceed 50 percent by weight of the entire mixture. Preferably, it should amount to 5 percent to 30 percent by weight.
• the kind and amount of the solvent used within the quantitative range are without essential importance with regard to the cleaning effect and the foaming capacity. However, they do exert an influence on the viscosity and to a certain measure also on the resistance to cold of the product.
• the amount of the solvent should be chosen so that the product is still sufficiently liquid even at relatively low-temperatures, which factor is guaranteed when its viscosity does not exceed 500 c? at a temperature of 20 C.
• spot removing compositions of the invention contain, in addition, from 2 percent to percent preferably from 4 percent to 7 percent, by weight of hydrotropic compounds of the group of low-molecular weight alkali metal alkylbenzenesulfonates.
• hydrotropic compounds of the group of low-molecular weight alkali metal alkylbenzenesulfonates are the alkali metal salts of toluenesulfonic acid, xylenesulfonic acids, ethylbenzenesulfonic acids and isopropylbenzenesulfonic acids.
• the water content of the spot-removing compositions of theinvention should not amount to more than percent by weight, preferably 1 percent to 10 percent by weight. It was discovered in a rather startling manner that the cleaning effectiveness of the agents is exceptionally intense when the indicated water content is observed in relation to grease soiled as well as mineral soiled articles.
• the preparation of the spot-removing compositions according to the invention is carried out by simply admixing the individual components, with or without melting as required.
• the spot-removing compositions distinguish themselves by an intense cleaning effectiveness, in particular, with regard to the persistent fatand oil-containing soiled items. Due to their low-viscosity, the penetration of the cleaning solution into the textile article to be cleaned is essentially facilitated so that even deep-seated spots can be treated with success.
• the spotremoving compositions react in a neutral manner, act as fiberprotecting agents and, consequently, they are also suitable for cleaning delicate fabrics. They possess foam-arresting properties so that the textiles treated with these agents can be washed with the usual moderately forming or low-foaming detergents in conventional household drum washers without any danger that the washing liquor might cause excess foaming.
• the products have a good storability, particularly at temperatures ranging from +10 to 0 C.
• the agents distinguish themselves favorably from numerous known liquid detergents, which during storage in the temperature range indicate either the tendency to have the components of the mixture separate or to develop a sedimentation.
• Such prior art products after reheating can be homogenized only with difficulty or not completely.
• EXAMPLES 1n the following the compositions of the several products are given in percent by weight.
• the abbreviations E0 and PrO mean the amount of added ethylene oxide or propylene oxide per me].
• the admixing of the components to form the spotremoving compositions of the invention is effected in that first of all the xylenesulfonate is dissolved by heating in the water content specified, followed by the addition of the remaining components in liquid or melted form. All of the preparations were clear liquids at room temperature. The viscosities were determined by means of a Brookfield rotating viscosimeter using a No. 2 spindle at a temperature of C.
