The invention relates to an aqueous cleaning agent for hard surfaces, in particular a hand dishwashing detergent, with improved oil solubilization and the use of this cleaning agent for cleaning hard surfaces, especially dishes.

Description

The The invention relates to an aqueous Cleaning agent for hard surfaces, in particular a hand dishwashing detergent, with improved oil solubilization and the use of this cleaner for cleaning hard Surfaces, especially dishes.

to Cleaning hard surfaces and especially for manual cleaning of dishes have become aqueous Detergents containing mixtures of anionic and amphoteric or nonionic surfactants, in particular with a surfactant combination from alkyl ether sulfate, sec. Alkanesulfonate and betaine, especially proven since These have a particularly good drying and drainage behavior.

It The question arose as to the properties of these detergents can be improved. Important Properties here are in particular the solubilization capacity and the Solubilization.

Surprisingly has now been found that by adding a nonpolar oil to the Detergent solubilization capacity increased by more than 40% and the solubilization rate more than doubled can, d. H. that the addition of the non-polar oil is both thermodynamic and also a kinetic effect in terms of cleaning performance causes the cleaning agent.

One The first object of the present invention is therefore an aqueous Cleaning agent for hard surfaces, in particular a hand dishwashing detergent, containing a nonpolar oil in an amount of 0.05 to 5 wt .-%.

The aqueous Contains cleaning agent preferably at least one surfactant, more preferably at least an anionic surfactant. In a preferred embodiment contains the inventive aqueous cleaning agent a combination of at least one anionic surfactant and at least a nonionic or amphoteric surfactant, wherein as anionic Surfactant preferably at least one alkyl ether sulfate and / or an alkanesulfonate is used. In a particularly preferred embodiment As anionic surfactant is a mixture of at least one alkyl ether sulfate and at least one alkanesulfonate used.

In a further preferred embodiment For example, at least one betaine is used as the amphoteric surfactant. Become Alkyl ether sulfates and betaines used, these are preferably in relation to 5: 1 to 3: 1 included. In a particularly preferred embodiment becomes an aqueous Detergent used, the at least one alkyl ether sulfate, at least one secondary Alkanesulfonate and at least one betaine, the ratio between Alkyl ether sulfates, secondary Alkanesulfonates and betaines is preferably 5: 2: 1 to 3: 1: 1. at the aqueous Cleaning agent is preferably a single-phase Medium.

The aqueous Detergent is preferably characterized by the fact that it a solubilization capacity K of greater than equal 3, preferably greater than or equal 3.4, more preferably greater than or equal 3.8, and / or a solubilization rate (dynamic solubilization) of less than or equal to 20,000 s, preferably less than or equal to 15,000 s, more preferably less than or equal to 10,000 s, in particular smaller equal to 8000 s. It is preferably further characterized from that the inventive aqueous cleaning agent an increase compared to the same detergent without nonpolar oil the solubilization capacity K by more than 20%, preferably more than 30%, more preferably more than 40% and / or an increase in the solubilization rate by at least the factor 2, preferably by at least the factor 3, more preferably by at least the factor of 3.5. The Determination of solubilization capacity and solubilization rate is in the embodiments described.

One The second subject of the invention is the use of a non-polar oil for increasing the solubilization capacity and / or solubilization rate for hard detergents Surfaces, preferably a surfactant combination of alkyl ether sulfate, secondary alkanesulfonate and betaine and optionally a high surfactant concentration, in particular have a high alkyl ether sulfate concentration.

A third subject of the invention is a process for increasing the solubilization capacity and / or solubilization rate of preferably high-surfactant hard surface cleaners with a surfactant combination of preferably alkyl ether sulfate, secondary alkanesulfonate and betaine. by adding one or more non-polar oils to the agent.

The inventive agent Can be used to clean hard surfaces and in particular for manual dishwashing. in this connection elevated the nonpolar oil the solubilization capacity and solubilization rate. The preferably used Betaine and especially the preferably used alkyl ether sulfate wear primarily to the cleaning effect, while the preferably used alkyl sulfonate especially the drying or process behavior positively influenced, d. H. especially the Drying rate increased and residue formation reduced; the optionally used water-soluble salt finally cares for the Adjustment of viscosity.

One fourth subject of the invention is therefore the use of an agent according to the invention for cleaning hard surfaces, especially dishes.

in the For the purposes of the present invention, the terms "fatty acids" or "fatty alcohols" or "their Derivatives "- so far not stated otherwise - representative for branched or unbranched carboxylic acids or alcohols or their derivatives having preferably 6 to 22 carbon atoms. The former are particular because of their vegetable base than on renewable raw materials based on ecological reasons, but without the teaching of the invention to limit to them. In particular, for example, according to the ROELEN's oxo synthesis available Oxo alcohols or their derivatives can be used accordingly.

When always below alkaline earth metals as counterions for monovalent Anions are called, so that means that the alkaline earth metal Naturally only in the half - to Charge balance sufficient - amount of substance as the anion is present.

Examples

Characterization methods:

1. Determination of Solubilization Capacity in HDW Formulations

Aim:

determination the maximum amount of oil, in a surfactant solution solved clearly can be.

Experimental method:

20 g surfactant solution are presented at room temperature in a beaker. The solution will be with a magnetic stirrer at 300 upm during touched by the whole experiment.

The oil is added gradually with a microliter pipette of 0.05 ml. As soon as the solution has cleared again, the next addition of oil. As the amount of oil increases, clearing up becomes slower and slower. The intervals between the oil addition are increased up to a maximum of 2 hours. If the sample remains cloudy over this period, then the maximum capacity for oil addition is reached. With the number of added oil drops n, the oil solubilization capacity K [% by weight] is calculated according to:

Meaning of the method:

With This method is determined visually, from which point an emulsification takes place. In an emulsification, energy must be expended, while The solubilization is voluntary because the change the free enthalpy in the process is negative. Practically means this, that at a solubilization cleaning performance without Force can occur.

2. Method for measuring the dynamic solubilization in HDW formulations

Aim:

Measurement the speed with the added amount of oil from a surfactant system be solved clearly can.

Experimental method:

100 ml of a surfactant solution are presented in a double-walled, heated beaker. The solution is during of the whole experiment homogenized with a paddle stirrer at 400 rpm.

A defined amount of oil, z. B. 0.5, 1.0 or 2.0 wt .-%, is added in one portion. With a haze meter, the transmission of the sample is recorded in% during the experiment. The wavelength of the light used is λ = 550 nm. After the addition of oil, the transmission abruptly decreases to a minimum value Tr _min , from this point, which is set as the zero point on the time axis, the clearing of the sample is followed. For comparison of different formulations, the required times can be compared, up to which the sample can be tested on z.
