Definitions
- the present invention relates to the technical field of hard surface treating agents, particularly to hard surface cleaners and to agents which protect surfaces from soiling and / or facilitate the removal of soil contaminants.
- agents have been found with which surfaces can be retrofitted and equipped in a way that can be carried out in a household so that they less easily pollute or easier to clean, at least for a certain period of use.
- copolymers which consist of at least one each of an anionic vinyl monomer, a vinyl monomer having a quaternary ammonium group or a tertiary amino group, and a nonionic hydrophilic vinyl monomer or a polyfunctional vinyl monomer. These copolymers are useful as anti-soiling components in detergents and are effective, for example, against fecal contamination.
- toilet cleaners for better lime solution are often after application for a long time, often several hours or even overnight, left to act on the ceramic.
- the formulations are usually thickened to improve the adhesion to the ceramic. When prolonged exposure then forms on the surface of a film that is usually colored due to the product coloring and after drying is difficult to remove.
- Biofilms consist of a thin layer of mucus (film) in which microorganisms (e.g., bacteria, algae, fungi, protozoa) are embedded. This can be not only a hygienic but also an aesthetic problem. As an antidote biocidal substances are often used. However, this is not always unproblematic in view of the ecotoxicological properties of many of these substances and the associated limitations in their application. In addition, biofilms contribute to the formation of unpleasant-smelling substances and are therefore a source of undesirable bad odors, especially in the sanitary sector.
- microorganisms e.g., bacteria, algae, fungi, protozoa
- agents for the treatment of hard surfaces must fulfill further requirements. So it is important that after the treatment of the surface their appearance is not affected. This is in particular the preservation of the gloss of surfaces which have a gloss in the original or clean state, and the avoidance of residues of the treatment agent, for example in the form of stripes or streaks.
- there has been a need for methods and means to provide a hard surface with soil repellency and / or to facilitate the release of soil and / or reduce the formation or adhesion of biofilms where these effects can be achieved optionally in a stand-alone surface treatment process, or in the course of a cleaning process, in which a surface is cleaned and at the same time provided with the aforementioned properties.
- US 2003/0153712 A1 discloses a polyurethane prepolymer having terminal alkoxysilane and hydroxyl groups.
- a polyether-diol is first reacted with stoichiometric diisocyanate, and the resulting isocyanate-hydroxy compound is then further treated with an aminosilane to introduce the silyl groups.
- the described, two-armed polyalkoxylates representing prepolymers are used for the production of sealants and adhesives.
- US 2004/0096507 A1 is concerned with six-armed polyethylene glycol derivatives and discloses a completely silyl-terminated derivative which can be prepared starting from sorbitol as the central unit.
- the polyethylene glycol derivatives described in the document are said to be suitable for the preparation of biodegradable polymeric hydrogels and for medical-pharmaceutical use, for example for implants.
- the object of the invention was therefore to remedy the above-described disadvantages of the prior art, at least partially.
- the object was to provide means for improving the removability of dirt and biofilms of hard surfaces, especially toilet ceramics, as well as the prevention of new formation of such soiling on such surfaces.
- silyl-polyalkoxylate-containing agents are particularly suitable to protect a surface treated therewith from contamination and / or to facilitate the removal of contaminants from the surface.
- the present invention therefore provides an agent for the treatment of a hard surface, in particular for the cleaning and / or dirt-repellent treatment of a hard surface, comprising a) at least one multi-arm silyl polyalkoxylate of the formula (I)
- Z is an (m + n) -valent radical having at least three carbon atoms
- A is a divalent polyoxyalkylene radical, where the m + n attached to Z
- Polyoxyalkylenreste may be different from each other, and wherein a radical A in each case via an oxygen atom belonging to Z with Z and one belonging to A.

- hard surfaces are in particular surfaces of stone or ceramic materials, hard plastics, glass or metal. It can be hard surfaces such as walls, work surfaces, floors or sanitary items.
- the invention relates to surfaces of ceramics, preferably sanitary ceramics, and more particularly of toilet bowls.
- the agent can be applied to the surface.
- the treatment of the surface is preferably carried out so that the agent is transferred to the surface by means of an absorbent fabric or that the agent is sprayed onto the surface.
- the treatment can also be done, for example, by immersing the surface in the agent.
- dirt or soiling are in particular fecal dirt and / or biofilms.
- the agent By treating a hard surface with the agent according to the invention, it is protected against contamination and / or facilitates the detachment of dirt from the surface.
- the agent prevents the formation of biofilms without having a biocidal effect. It is believed that the effectiveness of the biofilm formation agents of the present invention is due to a bacteriostatic effect of the silyl polyalkoxylates used, thereby inhibiting the colonization of surfaces with microorganisms and hindering their attachment and propagation to the surfaces. On the other hand, since no biocidal effects were observed for the agents, they are not subject to the disadvantages mentioned in the introduction of biocides.
- the agents of the present invention provide for easier soil removability and reduced tendency to re-soak and, in particular, improve the cleaning performance of hard surface cleaners. As a result, appropriately treated or cleaned surfaces are perceived longer than clean.
- silyl polyalkoxylates of the formula (I) as additives in surfactant-containing cleaning agents makes it possible not only to clean one surface in a single work step, but at the same time provides it with protection against dirt. In this way, for example, a calcification, an adhesion of protein or fat-containing dirt and the growth of bacteria is prevented. The treated surfaces stay clean longer and, moreover, the subsequent cleaning is greatly facilitated. This means that you need to clean the surfaces less often without sacrificing cleanliness, and their subsequent cleaning is associated with less effort insofar as it can be done in a time-saving manner and / or requires milder detergents. So it is possible in favorable cases, for a certain time alone with the help of water a sufficient To achieve cleaning effect, ie without the need for the use of a conventional cleaning agent.
- silyl polyalkoxylates of the formula (I) can be easily and simply formulated in the other constituents of the composition and, in particular, can be incorporated in a very simple manner into conventional detergent formulations.

After removal, the test surfaces were dried at room temperature for 1 min and then rinsed with running water. The amount and distribution of residual debris left on the surfaces (white fat layer) were used as criteria for the easy-to-clean effect.
- a synthetic Desikalanschmutzung according to the patent DE 103 57 232 B3 was prepared. Similar to the test procedure described there, the fecal soiling was applied punctiform (diameter 10 mm) to the test surfaces using a metal template and dried at room temperature for 15 min. After drying, the surfaces were rinsed in a laboratory rinse, which simulates the flushing of a toilet flush toilet, with evenly flowing water. The time (in seconds) that elapses from the start of the rinse to the time when the yellowish brown fecal stain was completely removed from the surfaces and the amount and distribution of residual debris (white fat layer) were used as criteria for the Easy -to-clean effect used. In addition, it was also taken into account whether the surfaces become dry again quickly after rinsing off.
- a calcium-magnesium-rich mineral water brand Contrex was used.
- the test surfaces were immersed in this water at room temperature for 24 hours. After removal, the test surfaces were dried in air for 2 hours and then in dist. Water immersed for 20 min. After removal, the test surfaces were air dried for an additional 2 hours. It was only followed by a qualitative visual assessment of whether and with what amount of lime the surfaces are covered. Thereafter, a quantitative determination of the amount of lime deposited on the surfaces was carried out. For this purpose, the accumulated lime was dissolved with dilute hydrochloric acid and the amount of calcium and magnesium ions in the resulting aqueous solution was determined by titration (standard method from Metrohm). The normalized amount of lime (mg / cm 2 ) was used as a criterion for the anti-lime effect.
- the biorepulsive performance of a test substance was determined in an adhesion test for microorganisms with the organisms Staphylococcus aureus DSM799 and Pseudomonas aeruginosa DSM939.
- the substances to be tested were applied to hard surfaces, which have relevance in the household, such.
- Specimens of 18x18 mm format were first washed with sterile and distilled water and dried. The thus prepared specimens were overlaid with a germ suspension and incubated for one hour. Subsequently, the seed suspensions were filtered off with suction and the test pieces were washed twice. After having been transferred into sterile test panels, the test specimens for S.
- aureus were overlayed with nutrient agar, and then incubated for 48 hours at 30 0 C.
- the specimens were shaken in buffer, then overlaid with nutrient agar plus 10% TZC and then incubated for 24 hours at 30 0 C.
- the shaking fluid was filtered through a membrane and the filters were incubated on Caso agar for 24 hours at 30 0 C.
- the extent of seed growth indicative of colonization of the specimens with nuclei is reported relative to an untreated surface, thereby setting the microbial load of the control specimen as 100%.
- coated surfaces (2 ⁇ 2 cm) were exposed to biofilm growth for 24 hours.
- the test specimens were placed in a microtiter plate consisting of 6 chambers.
- a germ mixture consisting of Dermacoccus nishinomiyaensis DSMZ 20448, Bradyrhizobium japonicum DSMZ 1982 and Xanthomonas campestris DSMZ 1526, which forms a stable biofilm in aqueous environments, was added at a bacterial count of 106 cfu / ml.
- the germs in the above-mentioned concentration together with a diluted complete medium 50 times DGHM-water-diluted TBY
- a diluted complete medium 50 times DGHM-water-diluted TBY
- test specimens were removed from the microtiter chambers for drying at room temperature and then stained with 6 ml of 0.01% safranine solution for 15 minutes. Thereafter, the dyeing solution was sucked off, and the test pieces were rinsed to remove the unbonded dye from the test pieces. After drying, the dyed test specimens were evaluated.
- test specimens were examined in an almost automatically running, application-oriented WC reactor, which simulates the function of a toilet from its construction.
- This system makes it possible to examine adhesion and biofilm formation in a test system on several different surfaces over a short and long period of time (in this case: total running time of two days).
- fresh medium TY / DGHM water 1:50
- the surfaces fall dry in phases and are then covered with liquid again. This change is very similar to the processes in a toilet, where the ceramic surfaces can also be alternately wetted or dried.
- the biofilms produced in the reactor correspond to those of microtiter plates in terms of strength and homogeneity.
- the reactor was first filled with 680 ml of medium, inoculated with the germ mixture described in 1.6.2 and incubated overnight, so that the bacterial flora could establish in the system.
- water flushing was done from a storage vessel by opening a solenoid valve, which in turn was controlled by a timer.
- the curvature of the toilet bowl was adjusted by clamping the specimens by means of an adapter in the reactor interior.
- Per Rinse was usually used about 600 ml_ of water.
- the first and second day post-incubation were each rinsed 15 times, with the single rinse lasting 20 minutes.
- the first specimen was taken in the morning on the first day, after there were no or few rinses.
- the second withdrawal took place in the afternoon after the rinses, overnight the reactor was filled with medium without rinsing.
- the specimens were dried after removal from the reactor at room temperature and then stained with 6 ml of 0.01% safranine solution for 15 minutes. Thereafter, the dyeing solution was sucked off, then the dyeing solution was sucked off, and the test pieces rinsed to remove the unbound dye from the test specimens. After drying, the dyed test specimens were scanned and evaluated with Corel Draw Paint 9. In order to be able to deduct the background value caused by the surfaces of the substrates used from the measured value, untreated surfaces were additionally scanned.
- Formulation A prepared in 2.1 was sprayed onto a cleaned tile or glass surface. After brief exposure, the surface was rinsed with running water. This gave a coating which is hydrophilic (water contact angle about 40 °) and at the same time water-wicking (low hysteresis). Because of this water-wicking property, the surface becomes instantly dry when rinsed with water.
- a cleaned slide (26 cm x 76 cm) was immersed in formulation D3 prepared in 2.6. After brief exposure, the surface was rinsed with running water. This gave a coating on both sides of the slide.
- the anti-lime test on the prepared surfaces was performed according to protocol 1.5, using as reference an untreated slide. Under identical conditions, it was found that hardly any calcification could be observed on the produced coating, whereas on uncoated surfaces a clear white layer of lime remained. Further quantitative determination by titration revealed a reduction of calcification by using the formulation according to the invention by about 90%.
- Formulation F1 Another formulation (Formulation F2) was prepared in an analogous manner but additionally containing tetraethoxysilane (on a weight basis double the amount of silyl polyalkoxylate). Coverslips (20mm x 20mm) were dipped in the respective formulation for 1 min, followed by rinsing with running water. The reference was an untreated cover glass. The results showed that both inventive formulations against both test organisms used (Staphylococcus aureus and Pseudomonas aeruginosa) compared to the uncoated control a comparably strong and compared to the reference a significant adhesion reduction on glass caused.
- the tests were carried out according to the procedure 1.6.2.
- the formulation F1 already described under 3.6.1 was used.
- the ceramic tiles 25 mm x 25 mm) were cleaned with ethanol, then dried. From about 15 cm distance, the formulation F1 was sprayed onto the cleaned tile, left for 15 minutes and then rinsed with water. After 15 minutes, the procedure was repeated to produce 4x, 5x and 7x sprayed tiles as a result.
- tiles were used as controls, which were sprayed only with the surfactant-containing agent (consisting of: C 8 -io-alkyl polyglycoside 2.5 g, lactic acid 2.0 g, water to 100 g).
- the tiles were then dried for 2 hours at 6O 0 C and then used for the tests.
- Tiles treated with Formulation F1 showed a marked visible biofilm reduction compared to control, with 7 fold sprayed tiles the effect was most pronounced. These effects were not based on biocidal effects, according to cultural analyzes.
- hydrophobic, especially superhydrophobic surfaces are often used to achieve easy-to-clean properties.
- a typical example is hydrophobic, rainwater repellent formulations for car windshields.
- a hydrophobic surface with a water contact angle of about 100 °, made of perfluorosilane was compared with a surface treated according to the invention with regard to its easy-to-clean effects.
- two formulations were first prepared: a mixture of the silyl polyalkoxylate of Synthesis Example 1 (0.50 wt%), water (0.25 wt%), acetic acid (0.25 wt%), and ethanol ( ad 100% by weight) was stirred at room temperature for 2 days (formulation G).
- the formulation prepared in 2.1 was tested in terms of appearance (cloudiness, precipitation, etc.) and its ability to produce the hydrophilic and water repellent surfaces of the present invention under real conditions (room temperature and normal humidity). The test was conducted one month apart. For this purpose, the formulation was applied to tile and glass surfaces as described above, and the resulting surfaces were evaluated for their wetting and dewetting with water. The results showed that the formulation did not change from appearance to effect within the test period (about 1 year), suggesting that it is stable under the conditions indicated.
- the formulation A prepared in 2.1 was sprayed onto a cleaned tile or glass surface. After brief exposure, the surface was rinsed with running water. This gave a coating which is hydrophilic (water contact angle about 40 °) and at the same time water-wicking (low hysteresis).
- the treated tile or glass surface was stored under normal conditions (room temperature and normal humidity) and evaluated for watering and dewetting one month apart. The results showed that no change in water wettability and water drainage behavior on the surface could be detected within the test period (about 8 months), indicating that the coating is stable under the conditions indicated.
- silyl polyalkoxylates from Synthesis Examples 2 and 3 Similar results were achieved both in the test with IKW ballast soil (see 1.2.) And in the test with shoe cream soil (see 1.3.) As with the silyl polyalkoxylate from Synthesis Example 1. All these substances were clearly superior to the reference in these tests to very clearly superior.
