Description

"Detergent or cleaning agent containing sucrose alkyl esters"

The present application is directed to a detergent or cleaning agent having improved cleaning performance, in particular to greasy stains, and a method for improving the cleaning performance of a detergent or cleaning agent.

The use of various surfactants in detergents or cleaners is well established in the art. As detergent substances they serve to increase the solubility of fat and dirt particles that adhere to the laundry in water. However, the performance of such agents on greasy soils is not always optimal, resulting in consumer dissatisfaction. For this reason, greasy soiling is often pretreated, which is also not very user-friendly. It is therefore a general endeavor to further optimize the cleaning performance of detergents or cleaners, especially on greasy soiling.

The present invention is therefore based on the object, a detergent or

Detergent with improved cleaning performance, especially on greasy

Stains, provide.

Surprisingly, it was found that the cleaning performance of detergents or cleaners, especially in terms of their cleaning performance of fatty

Soils, is significantly improved if the detergents or cleaners contain sucrose alkyl esters in addition to other surfactant components.

In a first aspect, the present invention is therefore directed to a detergent or cleaning agent, preferably liquid detergent, containing 0, 1 to 5.0 wt.%, Preferably 0.5 to 3.0 wt.% Saccharosealkylester.

In a further aspect, the present invention relates to the use of such a detergent or cleaning agent according to the invention, in particular as a laundry detergent.

In yet another aspect, the invention is directed to a washing process comprising the process steps

a) providing a washing solution comprising a detergent or cleaning agent as defined above, and

b) bringing into contact a textile with the washing solution according to (a). The use of the detergent or cleaning agent according to the invention makes it possible to achieve a very good cleaning performance, in particular against greasy soiling.

Furthermore, the use of sucrose alkyl esters to improve the

Cleaning performance, in particular the cleaning performance against greasy stains, a detergent or cleaning agent subject of the present invention.

Under cleaning performance (washing power) of a detergent or cleaning agent in the invention, the removal of one or more soiling, in particular

Laundry soils understood to be bleach-sensitive, enzyme-sensitive or surfactant-sensitive. The distance can be measured by a brightening of the soiling measured as well as assessed visually.

The detergents or cleaners can be detergents for textiles, carpets or

Be natural fibers. The detergents in the context of the invention also include washing aids which are metered into the actual detergent during manual or automatic textile washing in order to achieve a further effect. Furthermore, detergents in the context of the invention also include textile pretreatment and post-treatment agents, ie those agents with which the

Laundry item is brought into contact before the actual laundry, for example, to dissolve stubborn dirt, and also such agents that give the laundry further desirable properties such as comfortable grip, crease resistance or low static charge in one of the actual textile laundry.
