Description

The present invention relates to a method for Acceleration of drying and drainage behavior; aqueous surfactant Detergents for the Cleaning hard surfaces, especially dishes.

To aqueous surfactant-containing cleaning agents, in particular manual Dishwashing detergents, consumers make special demands, both the flushing performance, the skin compatibility as also concerning the aesthetic aspects.

First and foremost, they have to be cleansed with tensides and more Auxiliary and additives are formulated, which a complete removal of all contaminating residues from ensure the surfaces. This is today by the consumers just as natural as the presupposed skin-friendly properties.

In addition, there is also the demand for the simplest possible and convenient application of detergents. For example, the manual drying of wet, cleaned glasses, wet Crockery or cutlery by means of absorbent wipes from the Users perceived as annoying additional work.

The cleaned and wet surfaces dry in the air letting go is less labor intensive, but it takes time longer and thus delays the granting. Another requirement the user is therefore in detergents, which the Noticeably improve drying times.

In addition, this procedure leads to glossy (specular, reflective) hard surfaces, for example Glass, porcelain, ceramics, polymeric or metallic materials, regularly to form undesirable visible residues like stains (water stains) or stripes as well as to one Loss of gloss or dull appearance.

When removing a cleaned part from the rinsing liquor the liquid remaining on the surface runs first until slowly, until then their layer on the surface has become so thin that it no longer expires, but only still decreases by evaporation (dries). The in the liquid drop dissolved or emulsified residues then give Stripes or stains.

Another essential requirement of the detergent is therefore, that the cleaned and dried surfaces for aesthetic reasons no visible stripes or May have water stains.

WO 96/18717 A1 discloses a skin-friendly, liquid, aqueous hard surface cleaner in the form of a clear microemulsion which removes grease or bath dirt and leaves a shiny appearance on non-rinsed surfaces and 14 to 24% by weight of a Alkali metal salt of a C ₁₂ -C ₁₈ -Paraffinsulfonats, 2 to 6 wt .-% of an alkali metal salt of an ethoxylated C ₁₂ -C 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. A disadvantage is the unfavorable drying behavior of such compositions.

The subject of WO-A-94/11476 are dishwashing detergents based on a combination of certain different amphoterics Surfactants in conjunction with nonionic and anionic surfactants good cleaning power with a simultaneously excellent Should designate foaming.

The subject of US-A-5,906,972 are hand dishwashing detergents with improved fat dissolving capacity based on ether sulfates, which to improve the foam stability high purity amphoteric Surfactants included (column 4, lines 30-33).

There was therefore still a need for surfactant-containing Cleaning agents for cleaning hard surfaces, which are the overcome mentioned disadvantages and high cleaning efficiency and good residue behavior an improved expiration and Have drying behavior.

An object of the present invention was to provide the drying or flow behavior of aqueous surfactant solutions for Cleaning hard surfaces continues to improve significantly in particular, to accelerate the drying or the process.

H. In particular, they significantly increase the flow rate and thus reduce residue formation.

The present invention further relates to the use of a Means for cleaning hard surfaces, especially of dishes. Preferably, the Agent used for manual cleaning of hard surfaces, especially for manual cleaning of dishes. When Hard surfaces come next to dishes, glasses and cutlery also all other hard surfaces, in particular of polymeric or metallic materials in household and trade in Question.

Main advantage of use according to the invention this is due to the concomitant use of the amphoteric surfactant Glycine compounds of the general formula (I) clearly improved drying or drainage 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. Under drying In this case, the total drying is understood, in particular until neither moisture nor haptic on the surface Surface is noticeable, as well as in particular the drying following drainage.

Another advantage of use according to the invention is the continued high cleaning effect especially at greasy soiling.

test method

To test the drying rate was for all means the time course of weight loss from spilled Champagne flutes tracked. These were the champagne flutes first filled with detergent solution (rinse liquor) and then emptied quickly (within a few seconds) over the spout. The drainage begins immediately after the start of emptying. As runoff, this is the beading on the glass surface adherent retained drops after lowering the liquid level designated. The drain ends when finally the rinse liquor layer on the glass surface has become so thin is that it no longer runs off, but only by drying decreases.

For quantitative determination, this was done in an airtight Plastic box installed a scale and via an interface Using a computer to lose weight for a period of time measured by 500 seconds at 10 second intervals. To record only the expiration, the first 10 seconds became not considered for the evaluation.

The champagne flutes were tempered at 20 ° C and 40 ° C respectively Rinse liquor stocked. The concentration was 0.2 g of detergent per liter of rinsing liquor. The bottom of the chalice of the champagne flute attached tubular spout had a diameter of 15 mm and led the running rinse liquor on the balance away. Temperature and humidity were at the Measurements monitored with a hygrometer. For every rinse liquor 3 x 5 (15) measurements were made. It is averaged over 15 measurements each. To judge were the Drying rate and the residual moisture detected.

Definition - drying rate

In order to compare the rinsing agents in their drying behavior, the time was to untreated to below the water value Surfaces (= zero value, only with tap water 6-8 ° dH wetted) evaluated. The specified in the tables Times indicate the time at which the drying curves of pure water and cut the drainage curve of the surfactant solution or to achieve absolute dryness.

Definition - residual moisture

The after running, d. H. after 500 seconds remaining and no longer running amount of water is as residual moisture designated. Again, the rating in Tables 4 and 6 shown.

Drying and residue behavior

Usually, surfaces dry with detergents treated slower than untreated wetted surfaces, since the water flow through the adhering surfactant molecules is slowed down. Within the measuring system used could this can also be proven. So all formulations resulted after 30 seconds expiry time a residue of> 200 mg residual moisture, where on the untreated surface only <80 mg residual moisture remained. After these 30 seconds runs from the untreated surface no longer moisture and it starts drying by evaporation of the water.

As can be seen from the above values, show with surfactants treated surfaces a delayed flow behavior. To show the optimized drying behavior, the Time recorded at a drier surface in the Comparison to the untreated surface yields. This should mean that the items to be washed dries faster than usual with water is possible. The lately on the market come dishwasher detergents are already in this regard been optimized. The dishwashing detergents 11-17 show at 20 ° C a significantly better drying than the Comparative products (V2-V6).

At 40 ° C, within the given 500 seconds, the absolute dryness of the surfaces is achieved by tap water and the formulation of the invention. The order of the drying rate is shown in Tables 3 and 5.

As can be seen, the measurement results for the invention Formulations a significantly higher flow rate, i.e. a faster expiration or a better expiration behavior, as the formulations according to the known state of Technology.

So by using REMOTERIC® AM C is both halving the drying rate as well as the residual moisture in the To achieve a comparison to already optimized market products. In front all with the addition of smaller amounts, <5 wt .-%, the inventive Glycinates to usual formulations showed these surprising results.

Even at elevated temperature, especially the formulation shows A2 as the fastest-drying dishwashing detergent formulation. The use of REWOTERIC® AM C in dishwashing detergents increases the drying performance in the usual temperature ranges and at the same time the mildness of the whole formulation.
