BACKGROUND OF THE INVENTION 
This invention relates to a fluid, two-component washing agent of which one 
component is a cold-stable aqueous dispersion of substantially unsaturated 
fatty acids, which aqueous dispersion is stable at temperatures down to 
-10.degree. C. 
Two-component washing agents are preparations consisting of two separately 
prepared and stored washing agent components that are combined only 
immediately before or at the beginning of the wash process. The present 
invention concerns such an agent in which one component is in the form of 
a liquid concentrate containing fatty acids as well as other additional 
surface-active compounds or tensides, and the other component contains the 
alkali needed for the formation of soap. 
A wash process with the use of a two-component washing agent is known from 
British Pat. No. 338,121. The first component consists of soap-producing 
fatty acids such as palmitic acid, stearic acid or oleic acid that are 
present and mixed with emulsifying agents or solvents such as sulfated 
olive oil, hydrocarbons, terpentine and chlorohydrocarbons. The second 
component contains the alkalies required for the formation of soap such as 
alkali metal hydroxide, carbonates, bicarbonates, and silicates and is 
combined with the first component only in the washing solution. Bleaching 
components may be added in addition. This process has a number of 
disadvantages that are important especially in highly automated, 
commercial laundries. 
For example, the fatty acids mentioned are difficult to transport and dose 
automatically by themselves, while the simultaneous use of solvents from 
the series of hydrocarbons or chlorohydrocarbons poses considerable 
problems such as increased danger of fire and explosion or toxicological 
concerns. Besides, the reaction between the fatty acids, which are not 
present in a sufficiently fine dispersion, and the alkali proceeds 
relatively slowly, especially at washing temperatures below 65.degree. C. 
Furthermore, the reaction is inhibited or partly prevented by the wash, so 
that fatty acid deposits may form on the wash. 
Another process known from French Pat. No. 1,460,904 starts with aqueous 
fatty acid emulsions suitable for the formation of soap, which combine 
with the wash alkalies in the washing solution. The fatty acid, which is 
preferably technical grade oleic acid or a low-melting fatty acid mixture 
(up to a titer of 45.degree. C.), is emulsified in water with a nonionic 
emulsifying having a low HLB value agent such as monolaurate or 
monostearate of polyoxyethylene-sorbitan, with the addition of distilled 
tall oil, if desired. Alkaline substances are not to be added since these 
break up the emulsions. It has been found that the cleaning power of the 
preparations is comparatively low since the emulsifying agents employed do 
not contribute measurably to the washing power. Furthermore, the 
stability, especially the stability in cold temperatures, of the emulsions 
is inadequate since deemulsification occurs below the freezing point, 
which deemulsification is not readily reversible after heating. 
Liquids of the above-mentioned type, particularly in the form of highly 
concentrated preparations, continue to be interesting despite these 
problems. Highly concentrated substances help to keep the costs for 
packing, transport and storage low. As liquids they possess the added 
advantage of being readily transportable and dosable. This offers definite 
advantages for commercial laundries equipped with respective mixing and 
storage tanks as well as for household washing machines equipped with 
storing and dosing devices as are being developed at present. The dosing 
of detergent in these novel machines is specially adjusted for each wash 
program, which prevents wrong dosing, which is undesirable and places a 
strain on the waste water. 
OBJECTS OF THE INVENTION

avoided or the mentioned problems solved, is the production of a washing 
agent consisting of two components, A and B, component A consisting of an

-alkoxy-C.sub.2-3 -alkoxy-C.sub.2-3 -alkanols, and 
(h) from 15% to 30% by weight of water.

weight of the mixture of C.sub.1-4 -alkoxy-C.sub.2-3 -alkanols or 
C.sub.1-4 -alkoxy-C.sub.2-3 -alkoxy-C.sub.2-3 -alkanols, and 
(h) from 15% to 30% by weight of water. 
The fatty acids listed under (a) consists of from 60% to 100%, preferably 
from 65% to 95% by weight of the fatty acids of oleic acid. 
Polyunsaturated fatty acids, such as linoleic acid, may be contained in 
the fatty acids, in addition to oleic acid, in proportions of from 0 to 
25%, preferably 1% to 15% by weight of the fatty acids. The proportion of 
saturated fatty acids with 12 to 18 carbon atoms is from 0 to 35%, 
preferably 2% to 20% by weight of the fatty acids, with the proportion of 
stearic acid not to exceed 5% by weight, especially 3% by weight. Suitable 
fatty acid mixtures have the following composition (in % by weight): 
0 to 10%, preferably 0.1% to 5%, lauric acid, 
0 to 10%, preferably 0.5% to 5%, myristic acid, 
0 to 15%, preferably 1% to 10%, palmitic acid, 
0 to 5%, preferably 0 to 3%, stearic acid, 
60% to 100%, preferably 65% to 95%, oleic acid, 
0 to 25%, preferably 1% to 15%, linoleic acid 
The amount of the fatty acids listed under (a) is preferably from 30% to 
34% by weight of the aqueous dispersion. 
The potassium soap listed under (b) is derived from the fatty acids of 
aforementioned composition and is present preferably in proportions of 
from 12% to 15% by weight of the aqueous dispersion. 
The ethoxylated alcohols listed under (c) are derived from natural or 
synthetic alcohols, particularly oxoalcohols with 8 to 14, preferably 9 to 
12 carbon atoms. The oxoalcohols may be linear or have methyl groups in 
the 2 position. Also suitable are mixtures of natural fatty alcohols and 
those obtained by the oxoreaction. The average number of ethylene glycol 
ether groups is from 5 to 12, preferably 6 to 8. The proportion of the 
ethoxylated alcohols in the aqueous dispersion amounts to 15% to 25%, 
preferably 18% to 22% by weight. 
Component (d) consists of a sodium linear alkylbenzenesulfonate, having 
from 10 to 14 carbon atoms in the alkyl, especially 
dodecylbenzenesulfonate, in amounts of from 4% to 10%, preferably 6% to 8% 
by weight of the aqueous dispersion. 
The optical brighteners of component (e) are alkali metal salts, preferably 
Na and K salts of the substituted stilbenesulfonic acids and are derived 
from compounds of the formulas 
##STR1## 
in which the individual symbols Me, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 
have the following significance: 
Me=Na, K 
R.sub.1, R.sub.2 = --NHCH.sub.3, --NCH.sub.3 (CH.sub.2 CH.sub.2 OH), 
--N(CH.sub.2 CH.sub.2 OH).sub.2 
##STR2## 
R.sub.3, R.sub.4 =H, --CH.sub.3, --Cl, --OCH.sub.3, --COOCH.sub.3, --CN, 
--SO.sub.2 NR.sub.5 R.sub.6, --CONR.sub.5 R.sub.6 with R.sub.5 and R.sub.6 
=H or alkyl with 1 to 3 carbon atoms. 
Optical brighteners of the formula I, in which R.sub.1 and R.sub.2 
represent morpholino, diethanolamino or anilino radicals, are preferable. 
The optical brighteners are present in proportions of from 0.05% to 1%, 
preferably 0.1% to 0.7% by weight of the aqueous dispersion. 
The hydrotropic compounds mentioned under (f) may be urea and/or 
low-molecular weight alkyl or dialkylbenzenesulfonates such as toluene, 
ethylbenzene, cumene or xylene sulfonate in the form of the Na or K salts. 
Their proportion is preferably from 1.5% to 3% by weight of the aqueous 
dispersion. 
Component (g) consists of aliphatic C.sub.1 -C.sub.3 alkanols, such as 
ethanol, propanol and particularly isopropanol, as well as of the mixtures 
of the mentioned alkanols. The content of these alkanols in the products 
is preferably up to 8% by weight. Products with proportions of less than 
4% of the mentioned alkanols can also contain hydrotropically active ether 
alcohols derived from C.sub.1 -C.sub.4 -monoalkanols and ethylene glycol 
or propylene glycol or di-ethylene glycol. Suitable are methoxyethanol, 
ethoxyethanol, propoxyethanol, isopropoxyethanol, or butoxyethanol. 
The water content of the concentrated aqueous dispersion is from 15% to 
30%, preferably 15% to 22% by weight. The shelf-life of the concentrated 
aqueous dispersions is unlimited in the temperature range between 
+50.degree. C. and -10.degree. C. They do become pasty after several weeks 
of storage at a temperature of -10.degree. C., but do not deemulsify even 
under such extreme conditions and again form liquids upon rewarming that 
are easy to pour and quite clear. 
Other additives that may be present in the aqueous dispersions are 
biocides, fragrances, dyes, stabilizers, sequestering agents, neutral 
salts and optical brighteners of other types than those specified, but the 
proportion of such additives should not exceed a total of 10% by weight 
and preferably be less than 5% by weight, particularly less than 2% by 
weight, to prevent a negative influence on stability in cold temperatures. 
Component B, which is combined, before or at the beginning of the washing 
process, with the above-described aqueous dispersion to form fatty acid 
soaps, consists, in the simplest case, of an aqueous solution of alkalies, 
that is alkali metal hydroxides, carbonates, silicates, phosphates and 
polyphosphates, particularly of sodium or potassium, or mixtures of the 
above-mentioned alkaline compounds. The alkalinity as well as the amount 
of these alkalies is calculated such that the fatty acids are converted 
completely into soaps and that an excess of alkali remains beyond that, so 
that the pH of the washing solution is 9.5 to 14, preferably at least 10 
and especially 10.2 to 13.5. Other compounds with a sequestering effect 
may be present in addition to the alkalies or polyphosphates with a 
sequestering effect, such as the Na or K salts of polycarboxylic acids, 
hydroxypolycarboxylic acids, ether-polycarboxylic acids, 
aminopolycarboxylic acids, hydroxy-alkanephosphonic acids and 
aminopolyphosphonic acids. Examples of particularly serviceable compounds 
are nitrilotriacetic acid, ethylenediaminetetraacetic acid, 
diethylenetriaminepentaacetic acid, 1-hydroxyethane-1,1-diphosphonic acid, 
1-aminoethane-1,1-diphosphonic acid and aminotri-(methylenephosphonic 
acid). 
A liquid solution of wash alkalies that is easily dosed and especially 
resistant to cold temperatures and was found to be a particularly suitable 
component B for automated laundries has the following composition: 
(i) from 0.5% to 5% by weight of sodium tripolyphosphate, 
(j) from 0 to 25% by weight of potassium tripolyphosphate, where the total 
amount of tripolyphosphates is preferably from 5% to 20% by weight, 
(k) from 0 to 10% by weight, preferably from 1% to 5% by weight of sodium 
silicate of the composition Na.sub.2 O: SiO.sub.2 =1:1 to 1:3.5, 
(l) from 0.5% to 5% by weight of sodium ethylenediaminetetraacetate, 
(m) from 10% to 25% by weight, preferably 15% to 22% by weight of potassium 
hydroxide; and 
(n) the remainder up to 100% by weight of water. Preferably the amount of 
water is sufficient to dissolve all the constituents of component B at 
room temperature. 
The ratio of the mixture of component A with the liquid component B 
according to the above composition is 1:1 to 1:4, preferably 1:2 to 1:3, 
where the total amount of all wash-active components and washing alkalies 
in the washing solution amounts to 5 gm to 30 gm, preferably to 10 to 25 
gm, per kg of dry wash. 
More particularly, therefore, the present invention also resides in a 
washing agent consisting of two components, A and B, wherein component A 
is an aqueous dispersion of fatty acids consisting essentially of 
(a) from 25% to 35% by weight of a C.sub.12-18 fatty acid having from 60% 
to 100% of the fatty acids of oleic acid, 
(b) from 10% to 16% by weight of a potassium soap of said C.sub.12-18 fatty 
acid of (a), 
(c) from 15% to 25% by weight of an ethoxylate of from 5 to 12 ethoxylate 
units onto a primary alcohol selected from the group consisting of linear 
C.sub.8-14 -alkanols and C.sub.8-14 -2-methylated-alkanols, 
(d) from 4% to 10% by weight of a sodium C.sub.10-14 
-alkylbenzenesulfonate, 
(e) from 0.05% to 1% by weight of an alkali metal salt of substituted 
stilbenesulfonic acid optical brighteners, 
(f) from 1% to 5% by weight of a hydrotrope selected from the group 
consisting of urea and alkali metal salts of alkylbenzenesulfonates having 
from 1 to 2 alkyl groups with a total of 1 to 3 carbon atoms, 
(g) from 2% to 10% by weight of alcohols selected from the group consisting 
of C.sub.1-3 alkanols and mixtures of C.sub.1-3 alkanols with up to 50% by 
weight of the mixture of C.sub.1-4 -alkoxy-C.sub.2-3 -alkanols or 
C.sub.1-4 -alkoxy-C.sub.2-3 -alkoxy-C.sub.2-3 -alkanols, and 
(h) from 15% to 30% by weight of water; and Component B is an aqueous 
solution of alkalies consisting essentially of 
(i) from 0.5% to 5% by weight of sodium tripolyphosphate, 
(j) from 0 to 25% by weight of potassium tripolyphosphate, 
(k) from 0 to 10% by weight of a sodium silicate of the composition 
Na.sub.2 O:SiO.sub.2, 1:1 to 1:3.5, 
(l) from 0.5% to 5% by weight of sodium ethylenediaminetetraacetate, 
(m) from 10% to 25% by weight of potassium hydroxide, and 
(n) the remainder up to 100% by weight of water, where the amount of water 
is sufficient to dissolve all the constituents at room temperature; where 
the ratio of component A to component B in the combination for washing is 
from 1:1 to 1:4. 
The subject of the invention further is a washing process, using the two 
components, A and B, according to the above-mentioned compositions, mixing 
ratios and concentrations. Still other components may be added for these 
washing processes, such as sodium aluminosilicates capable of cation 
exchange as described in British Pat. No. 1,473,201 and copending, 
commonly-assigned Ser. No. 956,851, filed Nov. 2, 1978, greying inhibitors 
such as cellulose ether and cellulose mixed ethers, enzymes as well as 
bleaches containing active oxygen or active chlorine, optionally with the 
addition of bleach activators. As far as the stability of the respective 
compounds permits, these are also preferably in the form of solutions or 
dispersions, with an inadequate stability being corrected, if necessary, 
by enclosing the active substances in a capsule.

The following examples are illustrative of the practice of the invention 
without being limitative in any respect.

For the preparation of the component A aqueous dispersion, the fatty acid 
mixture was mixed with the amount of potassium hydroxide necessary to form 
soap as well as with the ethoxylate and the alkylbenzenesulfonate, which 
was in the form of a 50% aqueous solution, then the optical brightener 
dissolved in isopropanol was stirred in and finally the hydrotropic agent 
as well as water in the specified amount was added. 
The concentrates were yellowish, clear to slightly iridescent solutions 
that were thin liquids at room temperature and which remained clear and 
homogeneous after three weeks of storage in controlled temperature 
chambers at -10.degree. C. and +50.degree. C. A repeated temperature 
change between +50.degree. C. and -10.degree. C. did not cause 
deemulsification. The concentrates were miscible with water at any ratio. 
The following solutions, the constitutions of which are given in Table 3, 
were used as the alkaline component B (amounts in % by weight):
