"Low-foaming spot treatment agent for textiles"

Additional application to the German patent application P 16 17 119 · 0

It is known that at washing temperatures in the range from 30 to 60 ^° C., as prescribed for textiles made from synthetic fibers, silk, wool or from cotton equipped with synthetic resins and blended fabrics made from cotton and synthetic fibers, greasy soiling is often only incompletely removed by a conventional washing treatment. This applies above all to the dirty edges on collars or cuffs, shirts, blouses, smocks, etc. But even from items of laundry that can be boiled, particularly stubborn stains cannot be completely removed by a single wash treatment. It has therefore been recommended that the heavily soiled areas be rubbed in with a paste made from powder detergent with the addition of water or with special paste detergents, which mostly consist of water-containing mixtures of anionic and nonionic washing raw materials . However, the first-mentioned method has not proven itself in practice, especially the previously known cev / orrlonen rriKt ^ n-shaped preparations ^ GLcnüb-jr imrtriac!: I £ -on fobticcn v ^r or -.

and browned frying fats, often not sufficiently effective are. This is especially true in cases where the impurities were not immediately washed out again and could act on the textile material for a longer period of time. aside from that increase the known stain treatment agents mostly in undesirable ways, the foaming tendency of the Viaschiauge, so that In drum washing machines, even when using so-called foam-retarded detergents, the lye foams over can.

The subject of German patent application P 16 17 119 · 0 is a liquid, low-foam spot treatment agent that is marked is through a content

that there is no more than one glycol ether group for an average of four carbon atoms in the alkyl chain R _0.

It has now been found that the properties of this agent can be further improved. The subject of the invention is a means according to patent ......... (German patent application P 16 17 119 · 0), which is characterized in that the water-insoluble Polyethylanglyeol ether of the formula

is replaced in the PU a straight-chain, saturated or unsaturated alkyl radical having 12 to 18 carbon atoms and η is an integer from 5 to 12, the so it is chosen that for an average of four carbon atoms in the alkyl chain more than one and not more than three glycol ether groups omitted.

The manufacture of the polyethylene glycol ether of the FormeΓ

takes place in a known manner by reacting straight-chain, saturated or unsaturated fatty alcohols or synthetic ones Alcohols of the specified chain length with ethylene oxide.

Suitable compounds of the formula FU- (OCpHi,) -OH have, for example, the following composition:

R ^ = lauryl η = ■ jj - 6

Rj = myristyl η = J - 8

R = falmityl η = 4 - 10

The organic solvent to be used should have a boiling point not over and not-have as' 5O ⁰ 350 ⁰ C., Be physiologically largely harmless in the usual handling of funds and do not develop any offensive odor. Alcohols such as ethyl, n- or i-propyl alcohol, ethylhexanol, methylphenylcarbinol, and also ether alcohols such as diethylene glycol, monomethyl or monoethyl ethers of ethylene or propylene glycol or glycerol diethyl ether and amino alcohols such as mono-, Diethanolamine or triethanolamine. Also suitable are ketones such as acetone, methyl ethyl ketone and cyclohexanone; Ethers, such as dipropyl ether, diisopropyl ether and diiso butyl ether; Carboxylic acid esters, such as ethyl acetate, propyl acetate or glycol diacetate; aliphatic and hydroaromatic hydrocarbons, such as gasoline, methylcyclohexane, tetralin or decalinj, and chlorinated hydrocarbons, such as trichlorethylene or carbon tetrachloride. Mixtures of the abovementioned solvents are also used with advantage.

The proportion of solvents should be 50 percent by weight of the mixture not exceed and preferably "5 to JO weight percent be. The type and amount of solvent are within of the specified range of quantities for the cleaning effect and the foaming power is of no essential importance, but they influence the viscosity and to a certain extent also the Cold resistance of the product. The amount of solvent should be chosen so that the agent is still sufficiently liquid at relatively low temperatures, which then ensures

is effective when its viscosity at 20 ⁰ C does not exceed 500 cP.

The agents contain to improve the clear solubility and the viscosity behavior at low temperatures 2 to 10, preferably 4 to 7 percent by weight of hydrotropic compounds from the group of low molecular weight Alkylbenzenesulfonates. Suitable compounds are the alkali salts of toluene, xylene, ethylbenzene and isopropylbenzenesulfonic acid.

The water content of the mixtures should not exceed 15 percent by weight, preferably 1 to 10 percent by weight. It has surprisingly been found that the cleaning effect of the Medium when adhering to the specified water content against fatty as well as mineral contamination is particularly large.

The agents according to the invention are produced by simply mixing or melting the individual components together.

Similar to the agents described in the main application, the preparations according to the invention are characterized by a high cleaning effect, especially against stubborn greasy and oily soiling. Due to the low viscosity

the penetration of the cleaning solution into the to be cleaned Textile material facilitated, so that even deeper soiling can be treated successfully. The agents react neutrally, are gentle on the fibers and are therefore also suitable for sensitive people Textile types suitable. They have anti-foam properties, which is why the textiles treated with it without the risk of the washing liquor foaming over with the usual moderate or very weak foaming detergents can be washed in drum washing machines. The good storage stability should also be emphasized the means, especially at temperatures in the range of +10 up to 0 ° e. Possibly minor occurring in the cold Cloudiness does not affect the cleaning effect of the agents and dissolves completely when reheating to room temperature. In this respect, the agents differ advantageously from numerous known liquid cleaning preparations, when stored in the specified temperature range for Tend to segregate or to form precipitates difficult or no longer complete after rewarming let homogenize.

However, while the mixtures described in the main application in the treatment of textiles made of synthetic fibers adhere relatively firmly to the Paser and under unfavorable conditions not completely in the subsequent washing treatment Let wash out of the textile, the present agents do not have this disadvantageous property.
