EP1564283B1 - Surfactant combination - Google Patents

Description

The invention relates to an aqueous, liquid composition comprising a surfactant combination of (a) fatty alcohol ether sulfate with 1 to 4 EO, (b) sec. Sodium C _13-17 alkyl sulfonate in an amount, based on the agent, of from 0.1 to less than 30% by weight and (c) cocoamidopropyl betaine in a weight ratio (a): (b): (c) of 1 : 1: 1 to 3: 3: 1, as well as the use of the agent for cleaning hard surfaces, especially of crockery.

Following manual wet or wet cleaning of hard household and commercial surfaces with an aqueous surfactant-containing solution, the wet or wet hard surfaces are either simply allowed to dry or dried in a further operation, usually with the aid of an absorbent article. Allowing the surfaces to dry is less labor intensive, but takes longer and on glossy (reflective, reflective) hard surfaces, such as glass, porcelain, ceramic, plastic or metal, regularly results in the formation of undesirable visible residues such as stains (water stains) or streaks also to a loss of gloss or dull appearance. This is especially true for the manual cleaning of dishes, especially glasses and other dishes made of glass when the dishes are first cleaned in a so-called rinsing liquor, an aqueous solution of a surfactant-containing agent, usually at elevated temperature of, for example, about 45 ° C and then not with a absorbent cloth is dried but allowed to air dry. When removing a cleaned glass or plate from the rinsing liquor, the rinse liquor is first poured out or poured off and glass or plate for drying. The rinsing liquor layer remaining on the surface of the glass or plate now slowly drains off until finally the rinsing liquor layer on the surface has become so thin that it no longer runs off, but only decreases by (self-) drying. The drying also takes place during the process.

The international patent application WO 96/18717 A1 ( Colgate-Palmolive Company ) discloses a skin mild liquid aqueous cleaner for hard surfaces in the form of a clear microemulsion that effectively removes grease soils as well as non-rinsed Surface leaves a shiny appearance and 14 to 24 wt .-% of an alkali metal salt of a C _12-18 -Paraffinsulfonats, 2 to 6 wt .-% of an alkali metal salt of an ethoxylated C _12-18 Alkylethersulfats and 2 to 8 wt .-% of a betaine surfactant and a nonionic surfactant, at least one solubilizer, a cosurfactant and a water-insoluble hydrocarbon, a perfume or an essential oil.

The object of the present invention was to improve the drying or flow behavior of aqueous surfactant-containing solutions for cleaning hard surfaces, in particular to accelerate drying or running.

The invention relates to an aqueous, liquid agent containing a surfactant combination of (a) fatty alcohol ether sulfate with 1 to 4 EO, (b) sec. Sodium C _13-17 alkyl sulfonate in an amount, based on the agent, of from 0.1 to less than 30% by weight and (c) cocoamidopropyl betaine in a weight ratio (a) :( b) :( c) of 1 : 1: 1 to 3: 3: 1.

The weight ratio (a) :( b) :( c) is preferably 1.5: 1: 1 to 2: 2: 1, most preferably about 2: 1: 1.

The agent according to the invention is suitable as a cleaning agent for hard surfaces and in particular as a hand dishwashing detergent (in short: dishwashing detergent). Here, the betaine and especially the alkyl ether sulfate contribute primarily to the cleaning effect, while the alkylsulfonate especially the drying or flow behavior positively influenced, i. in particular, increases the drying rate and reduces the formation of residues.

The second object of the invention is therefore the use of an agent according to the invention for cleaning hard surfaces, in particular dishes. Preferably, the agent according to the invention is used for the manual cleaning of hard surfaces, in particular for the manual cleaning of dishes. In addition to tableware, all other hard surfaces, in particular of glass, ceramic, plastic or metal, in household and in trade are also considered hard surfaces.

Advantage of the composition according to the invention or the use according to the invention is the favorable drying or flow behavior, in particular the high drying rate or short drying time, the high flow rate or short expiration time and the low residue formation and the preserved gloss. Drying here is understood to mean both drying as a whole, in particular until moisture or haptic moisture is not perceptible on the surface, and in particular drying following drainage.

A further advantage of the composition according to the invention or the use according to the invention is the high cleaning action (synonyms: cleaning performance or ability or rinsing action, performance or ability), especially for greasy stains.

Yet another advantage of the composition according to the invention is the high storage stability.

In the context of the present invention are fatty acids or fatty alcohols or their derivatives - unless otherwise stated - representative of branched or unbranched carboxylic acids or alcohols or their derivatives having preferably 6 to 22 carbon atoms. The former are particularly preferred for their vegetable base as based on renewable raw materials for environmental reasons, but without limiting the teaching of the invention to them.

Preferred sugar surfactants within the scope of the teaching according to the invention are the alkyl polyglycosides and the sugar amides and their derivatives, in particular their ethers and esters. The ethers are the reaction products of one or more, preferably one, sugar with one or more hydroxy-containing compound, such as C _1-22 alcohols or glycols such as ethylene and / or propylene glycol, wherein the polyethylene glycol also Zuckerhydroxygruppe - And / or polypropylene glycol can carry. The esters are the reaction products of one or more, preferably one, sugar hydroxy group with a carboxylic acid, in particular a C _6-22 fatty acid.

Particularly preferred sugar amides are the amides of glucose, the glucamides, for example lauroyl-methyl-glucamide.

Alkylpolyglykoside

The alkylpolyglycosides (APG) are particularly preferred sugar surfactants within the scope of the teaching according to the invention and preferably satisfy the general formula R ⁱ O (AO) _a [G] _x in which R ^{i is} a linear or branched, saturated or unsaturated alkyl radical having 6 to 22 , preferably 6 to 18, in particular 8 to 16, particularly preferably 8 to 14 carbon atoms, [G] for a glycosidically linked sugar residue and x for a number from 1 to 10 and AO for an alkyleneoxy group, for example an ethyleneoxy or propyleneoxy group, and a represent the average degree of alkoxylation of 0 to 20. In this case, the group (AO) _{a may} also contain different alkyleneoxy units, for example ethyleneoxy or propyleneoxy units, in which case a is the average total degree of alkoxylation, ie the sum of degree of ethoxylation and degree of propoxylation. Unless otherwise stated below, the alkyl radicals R ^{1 of} the APG are linear unsaturated radicals having the stated number of carbon atoms.

APG are nonionic surfactants and are known substances that can be obtained by the relevant methods of preparative organic chemistry. The index number x indicates the degree of oligomerization (DP degree), ie the distribution of monoglycerides and oligoglycosides, and stands for a number between 1 and 10. While x must always be an integer in a given compound and above all the values x = 1 to 6, the value x for a given alkyl glycoside is an analytically determined arithmetic size, which is usually a fractional number. Preferably, alkyl glycosides having a mean degree of oligomerization x of 1.1 to 3.0 are used. From an application point of view, those alkyl glycosides whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.6 are preferred. The glycosidic sugar used is preferably xylose, but especially glucose.

The alkyl or alkenyl radical R ⁱ can be derived from primary alcohols having 8 to 18, preferably 8 to 14 carbon atoms. Typical examples are caproic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as for example, in the course of the hydrogenation of technical Fettsäuremethylestem or in the course of the hydrogenation of aldehydes from the ROELEN's oxo synthesis incurred.

Preferably, however, the alkyl or alkenyl radical R ⁱ is derived from lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol or oleyl alcohol. Also to be mentioned are elaidyl alcohol, petroselinyl alcohol, arachidyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol and technical mixtures thereof.

Particularly preferred APG are not alkoxylated ( a = 0) and satisfy the formula RO [G] _x , in which R is as previously described for a linear or branched, saturated or unsaturated alkyl radical having 4 to 22 carbon atoms, [G] for a glycosidically linked sugar radical, preferably glucose residue, and x is a number from 1 to 10, preferably 1.1 to 3, in particular 1.2 to 1.6. Accordingly, preferred alkyl polyglycosides are, for example, C _8-10 and C _12-14 alkyl polyglucoside having a DP degree of 1.4 or 1.5, especially C _8-10 alkyl-1,5-glucoside and C _12-14 alkyl-1,4-glucoside.

Preferred cationic surfactants are the quaternary surface-active compounds, in particular having an ammonium, sulfonium, phosphonium, iodonium or arsonium group, as described, for example, by KH Wallhäußer in "Praxis der Sterilisation, Disinfection - Conservation: Germ Identification - Company Hygiene" (5th ed. Stuttgart, New York: Thieme, 1995) as antimicrobial agents. Through the use of quaternary surface-active compounds with antimicrobial action, the agent can be designed with an antimicrobial effect or its possibly existing antimicrobial effect due to other ingredients can be improved.

Particularly preferred cationic surfactants are the quaternary ammonium compounds (QAV, INCI quaternary ammonium compounds) according to the general formula (R ^I ) (R ^II ) (R ^III ) (R ^IV ) N ⁺ X ^- , in which R ^I to R ^{IV are the} same or various C _1-22 -alkyl radicals, C _7-28 -aralkyl radicals or heterocyclic radicals, where two or, in the case of an aromatic incorporation as in pyridine, even three radicals together with the nitrogen atom, the heterocycle, for example, a pyridinium or imidazolinium compound, represent and X ^{- are} halide ions, sulfate ions, hydroxide ions or similar anions. For optimum antimicrobial activity, preferably at least one of the radicals has a chain length of 8 to 18, in particular 12 to 16, carbon atoms.

QACs are prepared by reacting tertiary amines with alkylating agents, e.g. Methyl chloride, benzyl chloride, dimethyl sulfate, dodecyl bromide, but also ethylene oxide produced. The alkylation of tertiary amines with a long alkyl radical and two methyl groups succeeds particularly easily, and the quaternization of tertiary amines with two long radicals and one methyl group can be carried out with the aid of methyl chloride under mild conditions. Amines having three long alkyl radicals or hydroxy-substituted alkyl radicals are less reactive and are preferably quaternized with dimethyl sulfate.

Suitable QAVs are, for example, benzalkonium chloride (N-alkyl-N, N-dimethylbenzylammonium chloride, CAS No. 8001-54-5), benzalkone B ( m, p- dichlorobenzyl-dimethyl-C ₁₂ -alkylammonium chloride, CAS No. 58390-78 -6), benzoxonium chloride (benzyldodecyl-bis (2-hydroxyethyl) ammonium chloride), cetrimonium bromide (N-hexadecyl-N, N-trimethyl-ammonium bromide, CAS No. 57-09-0), benzetonium chloride (N, N -dimethyl-N- [2- [2- [p - (1,1,3,3-tetramethylbutyl) phenoxy] ethoxy] ethyl] benzylammonium chloride, CAS No. 121-54-0), dialkyl dimethyl such as di- n - decyl-dimethyl-ammonium chloride (CAS No. 7173-51-5-5), didecyldimethylammonium bromide (CAS No. 2390-68-3), dioctyl-dimethylammoniumchloric, 1-cetylpyridinium chloride (CAS No. 123-03-5) and thiazoline iodide ( CAS No. 15764-48-1) and mixtures thereof.

drying rate

To check the drying rate, the time course of the weight loss of glass plates wetted with detergent solution was followed for means E1 and V2 to V4 .

The temperature of the detergent solution (washing liquor) was here as well as the plate 20 ° C, the Spülflottenauftrag per glass plate at least 0.05 g and the concentration 0.4 g of detergent per liter of rinsing liquor. First, flat glass plates, the dry weight of which had been previously determined, were finely sprayed with a wafer-thin layer of the rinsing liquor for about 10 seconds with an inner diameter of 16.5 cm with a compressor-operated airbrush spray nozzle. The plate was held approximately at an angle of 90 ° to the spray. The spray time of about 10 seconds, in which at least 0.05 g of rinsing liquor are applied to a plate, had been determined in preliminary experiments. The plate was then placed on a scale connected to a computer and from a wetting of the plate with even 0.05 g of rinsing liquor, ie from a 0.05 g over the weight of the dry plate weight, until the complete dryness of the plate, ie until reaching the weight of the dry plate, held by the computer every second the weight of the plate. The humidity was determined by means of a hygrometer placed immediately next to the balance and was between 35 and 46% r. L. (relative humidity). For each rinse liquor 6 measurements were carried out.

A comparison of the mean values from 6 measurements leads to the following result: The drying rate of the SAS-containing formulas (E1 and V4) appears to be slightly higher than that of the SAS-free formulas V2 and V3.

From the averages of the 6 measurements in each case, the following order of decreasing drying speed resulted: E1>V4>V2> V3 . The agent according to the invention thus showed a higher drying rate, ie faster drying or a better drying behavior, than the four comparison agents.

running speed

To check the flow rate, the time course of the weight loss of champagne flutes with outlet was followed for the means E5 and E11 and V1 to V3 , which were first filled with detergent solution (rinsing liquor) and then run empty.

In this case, the level of the champagne flute drops rapidly, while above the sinking level, the expiration of the wash liquor to be examined with regard to the speed begins. As soon as the level drops to the level of the spout and thus to zero, only the drainage of interest here takes place. The drainage ends when finally the Spülflottenschicht on the glass surface has become so thin that it no longer expires, but only decreases by drying.

For this purpose, a scale was installed in an airtight plastic box. Through an interface, a computer recorded the weight loss for a period of 5 minutes every second. To record only the expiration, the first 12 seconds were not considered for the evaluation. The champagne flutes were equipped by means of a pump with the rinsing liquor heated to 45 ° C. The concentration was 0.4 g of detergent per liter of rinse liquor. The tubular spout attached to the chalice of the champagne flute had a diameter of 15 mm and guided the draining rinse liquor over the balance. Temperature and humidity were measured during the measurements monitored with a hygrometer. For each rinse liquor, 10 measurements were made.

Averaged over every 10 measurements, the following sequence of decreasing sequence speed resulted: E11>E5>V2>V3> V1. Thus, the two agents according to the invention showed a higher flow rate, ie a faster drainage or a better flow behavior, than the three comparison means.
