Description

 "Composition for the removal of bad smells"

The present invention relates to a composition for the removal of unpleasant odors from textiles, hard surfaces and / or from rinsing and washing machine interiors, the composition comprising at least two odor-neutralizing components and optionally at least one perfume. Furthermore, the present invention relates to a

Cleaning or washing agent and a device comprising a composition described herein. Further, the present invention is directed to a method employing such a composition or a detergent or a detergent described herein or a device described herein. Finally, the present invention is directed to the use of a composition, detergent, or device, as described herein, to remove odors from textiles, hard surfaces, and / or rinsing or washing machine interiors.

Bad smells can often be observed in the interior of dishwashers and washing machines as well as in cleaned articles and textiles. Even with insufficient

Cleaning performance may include undesirable bad odors due to biofilm formation in the

Dishwasher interior occur. Furthermore, cleaning programs with a long drying time and high humidity lead to bad odors. This gives the consumer an impression of lack of freshness and hygiene, both in the machines used and on the objects to be cleaned itself. In order to counteract this impression and the bad smell, fragrances are often used, which the

However, only cover bad odor, so that often only an insufficient freshness and hygiene impression is caused.

It has now surprisingly been found that the use of a composition containing at least two odor-neutralizing components and optionally at least one perfume, bad odors on hard surfaces and textiles and in the rinsing and

Washing machine interior prevents and produces an excellent freshness and hygiene impression at the consumer.

The present invention further relates to an agent, in particular a machine

Dishwashing or laundry detergent comprising the composition of the invention.

Furthermore, the present invention is directed to a device containing the composition described herein, preferably a textile, a nebulizer or a capsule.

Furthermore, the present invention relates to a method for cleaning hard surfaces or textiles, wherein in at least one step, a composition, washing or cleaning agent or device described herein is used.

Finally, the present invention is directed to the use of a composition, a detergent or a device as described herein

Removal of bad odors from textiles, hard surfaces and / or rinsing and washing machine interiors.

Summary of the experiments:

Thus, it has been successfully demonstrated that compositions according to the present invention do not result in a reduction of bad odor on textiles washed with the compositions of the present invention immediately after application of the bad odor mixture (2 hours), but have a marked long-term (from 4 hours) effect for reduction of bad smell. This effect has not only been observed with fabric softeners, but also with heavy-duty detergents, and experiments have shown that these results can be transferred to other detergents and cleaners.
