Description

The invention relates to the use of alkyl glycosides and alkyl ethers to strengthen the germ-reducing effect of disinfectant-containing Hard surface cleaners and disinfectant cleaners for hard surfaces with selected disinfectants. All non-textile that occur in the household are hard surfaces Understand surfaces, e.g. B. floors, work surfaces, kitchen appliances, Sinks, shower and bath tubs, toilet bowls, dishes etc.

Disinfectant cleaning agents are known; so far, however, it is not successful, optimal cleaning performance and optimal disinfection effect connect with each other. Common disinfectant detergents included e.g. quaternary ammonium compounds in connection with nonionic Surfactants; such cleaning agents have sufficient disinfectants Effect, their cleaning performance leaves something to be desired. On the other hand, a replacement of the non-ionic surfactants by cleaning agents anionic surfactants have the disadvantage that the disinfectant effect wears off strongly.

The object of the present invention is based on disinfectant-containing Prior art cleaning agents such surfactant combinations to find the - in addition to good cleaning performance - for an increase in the germ-reducing effect of the detergents disinfectant contained.

Another job is to use detergents for hard surfaces to develop selected disinfectant agents that both have a good cleaning performance as well as a good disinfectant effect.

The German published documents DE 34 44 958 and DE 36 19 375 describe the use of alkyl glycosides as potentiating agents Increasing the microbicidal activity of biguanide compounds or Alcohols and carboxylic acids, especially in personal care products.

In the international patent application WO 86/5199 cleaning agents discloses the surfactants alkyl glycosides, amine oxides and quaternary ammonium compounds contain.

International patent application WO 86/5509 discloses disinfectants Detergents that act as surfactant alkyl glycosides and as disinfectants contain quaternary ammonium compounds. The cleaning effect however, these compositions leave something to be desired.

Finally, the German patent application DE 40 01 758 disinfectants Detergent for automatically operated systems for Spray disinfection of hospital furnishings described a quaternary ammonium compound and the reaction product as disinfectant of N-substituted propylenediamines with glutamic acid or Contain glutamic acid esters.

None of the documents contained in the prior art disclose the Use of the special surfactant combination described below for Enhance the germ-reducing effect of disinfectant-containing Detergents.

Diese Mischung gewährleistet eine Verstärkung der keimreduzierenden Wirkung von desinfektionsmittelhaltigen Reinigungsmitteln für harte Oberflächen gegenüber solchen desinfizierenden Reinigungsmitteln, die nur eines oder keines der beiden genannten Tenside enthalten.

The object on which the invention is based, described above, was achieved by using a mixture of

a) an alkyl and / or alkenyl oligoglycoside of the formula (I), R ¹ -O- [G] _p in which R ^{1 is} a linear or branched alkyl or alkenyl radical having 8 to 22 carbon atoms, [G] is a glycose unit having 5 or 6 carbon atoms, preferably a glucose unit, and p is a number from 1 to 10
and

b) an alkyl ether of the formula II,

in which R ^{2 is} a linear or branched aliphatic alkyl and / or alkenyl radical having 8 to 18, preferably 8 to 14, carbon atoms, x for 0 or numbers of up to 3, preferably up to 2, and y for numbers from 1 to 15, preferably 2 to 12, in particular 2.5 to 10, is. This mixture ensures an increase in the germ-reducing effect of disinfectant-containing cleaning agents for hard surfaces compared to disinfectant cleaning agents that contain only one or neither of the two surfactants mentioned.

Alkyl and / or alkenyl oligoglycosides are known substances that obtained according to the relevant procedures of preparative organic chemistry can be. Representing the extensive literature referred to the documents EP-A1-0 301 298 and WO 90/3977.

The alkyl and / or alkenyl oligoglycosides can differ from aldoses or Derive ketoses with 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or Alkenyl oligoglucosides.

The index number p in the general formula (I) gives the degree of oligomerization (DP degree), i.e. the distribution of mono- and oligoglycosides on and stands for a number between 1 and 10. While p in a given connection must always be an integer, especially the values p = 1 to 6 can assume, the value p for a certain alkyl oligoglycoside is one analytically determined arithmetic size, usually a fraction Represents number. Alkyl and / or alkenyl oligoglycosides are preferred with an average degree of oligomerization p of 1.1 to 3.0. From an application point of view, such alkyl and / or alkenyl oligoglycosides are preferred, the degree of oligomerization between 1.4 and 2.0 lies.

The alkyl or alkenyl radical R ¹ can be derived from primary alcohols with preferably 8 to 11 carbon atoms. Typical examples are caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis. Alkyl oligoglucosides of chain length C ₈ -C ₁₀ (DP = 1 to 3) are preferred, which are obtained as a preliminary step in the separation of technical C ₈ -C ₁₈ coconut fatty alcohol by distillation and with a proportion of less than 6% by weight of C ₁₂ - Alcohol can be contaminated and alkyl oligoglucosides based on technical C _9/11 oxo alcohols (DP = 1 to 3).

The alkyl or alkenyl radical R ¹ can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol and their technical mixtures.

The alkyl ethers of the formula II are known nonionic surfactants which are obtained by adding initially propylene oxide and then ethylene oxide or exclusively ethylene oxide to fatty alcohols. Typical examples are alkyl ethers of the formula (II) in which R ^{2 represents} an alkyl radical having 12 to 18 carbon atoms, x represents 0 or 1 and y represents numbers from 2 to 5. The indices x and y represent mean values. Further, particularly suitable, alkyl ethers of the formula II are, for. B. C _12-14 fatty alcohol x 6 EO, octanol x 4 EO and C _10-14 fatty alcohol x 1 PO x 6 EO; EO stands for ethylene oxide, PO stands for propylene oxide. The alkyl ethers of the formula II can preferably have a narrow homolog distribution; in these cases, formulations with particularly advantageous physical properties are obtained.

As disinfectant ingredients, also called disinfectants, in principle all commercially available disinfectants can be considered, which are for use on hard surfaces, especially all in Hard surfaces that occur in the household. To be mentioned e.g. disinfectant quaternary phosphonium compounds, biguanide compounds, (e.g. chlorhexidine) while e.g. Phenols and aldehydes can be used in principle, but for human toxicological reasons should preferably not be used.

Test methods : Determination of the germ reduction

The germ-reducing effectiveness of the cleaning agents was tested in a quantitative suspension test based on the guidelines for the testing and evaluation of chemical disinfection processes of the German Society for Hygiene and Microbiology (DGHM), status 1981, against the bacterial strain Pseudomonas aeruginosa. For this purpose, 10 ml of the cleaning agent to be tested was mixed with 0.1 ml of a germ suspension (approx. 10 ⁸ -10 ⁹ germs per ml) at 20 ° C. After an exposure time of 5 or 10 minutes, 1 ml of these mixtures in each case in 10 ml of an aqueous disinhibiting solution containing 3.0% by weight of Tween ^(R) 80, 0.3% by weight of lecithin and 0.1% by weight. % Histidine. 0.1 ml of these samples and a further 1:10 dilution step were each applied to casein soy agar plates. After incubation of these subcultures (48 hours at 30 ° C), the number of germs capable of reproduction was determined. For comparison, aqueous solutions of the individual components and detergent-free water were tested under the same conditions. The difference between the active ingredient preparation and the negative control is given in the table as a logarithm (= reduction factor, [log levels]).

Determination of cleaning ability

The test method described below according to "Seifen-Öle-Fette-Wwachs", 112 , 371, (1986) was used to test the cleaning ability and provides very reproducible results. The cleaning agent to be tested was then placed on an artificially soiled plastic surface. A mixture of carbon black, machine oil, triglyceride, saturated fatty acids and low-boiling aliphatic hydrocarbon was used as artificial soiling for the dilute use of the cleaning agent. The test area of 26 x 28 cm was evenly coated with 2 g of the artificial soiling with the aid of a surface coater.

A plastic sponge was each with 10 ml of a 1 wt .-% aqueous Solution of the cleaning agent to be tested soaked and mechanically on the also with 10 ml of a 1% by weight aqueous solution of the test Detergent coated test area moves.

After 10 wiping movements, the cleaned test area was covered with flowing Water is kept and the loose dirt is removed. The cleaning effect, i.e. the whiteness of the plastic surface cleaned in this way measured with a color difference measuring device "Microcolor" (Dr. B. Lange). The clean white plastic surface served as the white standard.

Because when measuring the clean surface set to 100% and the soiled area is displayed with 0%, are the read values for the cleaned plastic surfaces with the percentage cleaning capacity (% RV) equate. In the experiments below, these are % RV values given the values for the Cleanability of the investigated cleaning agents. You pose each Mean values from triple determinations.

The measured values were set in relation to the cleaning result of a cleaning-strong, non-disinfectant cleaning agent used as standard. Measured values sample · 100 Measured value standard =% RV relative
