Abstract

A sprayable cleaning composition comprises a surfactant combination of one or more sarcosinates, one or more amine oxides and optionally one or more fatty alcohol polyglycol ethers, and can be used to clean hard surfaces. In a corresponding cleaning process, the composition is applied to the surface to be cleaned with a spray dispenser with a foam nozzle or a pumped foam dispenser, and can be removed virtually without residues or streaks.

Description

"Sprayable all-purpose cleaner"

The subject of this application is a sprayable cleaning agent for hard surfaces, which contains a surfactant combination consisting of one or more sarcosinates, one or more amine oxides and optionally one or more fatty alcohol polyglycol ethers. This allows a virtually residue- and streak-free cleaning hard surfaces and also facilitates the cleaning of vertical surfaces.

When cleaning hard surfaces, it is always desirable that the cleaning agent is in turn completely removed after successful removal of the soiling and dries residue-free if possible. In particular, on glass surfaces, dark tiles or glass ceramic cooktops otherwise remain unsightly streaks and streaks, which can only be removed by increased workload.

Furthermore, it is desirable, especially in vertical surfaces, that the cleaning agent does not run off immediately after application, but remains adhering to the dirt for a certain time to allow a better release of the dirt by the longest possible exposure time. This can be effected, for example, by applying the detergent in the form of a stable foam. However, this foam should quickly disintegrate during subsequent wiping with a cloth, sponge, leather or other suitable substrate to ensure the desired residue-free cleaning even without wet wiping.

It was therefore desirable to formulate a cleaning agent, which can be applied with good fat dissolving capacity on the largest possible number of surfaces with the longest possible contact time and thereby dries strip and residue.

It has now been found that a cleaning agent with a surfactant combination of sarcosinates, amine oxides and optionally fatty alcohol polyglycol ethers is readily sprayable, in particular using a foam trigger, and dries residue-free.

The subject of this application is therefore a sprayable cleaning agent for hard surfaces, which contains a surfactant combination consisting of one or more sarcosinates, one or more amine oxides and optionally one or more fatty alcohol polyglycol ethers. This formulation has a good grease-dissolving power and can be removed without wet wiping residue-free and streak-free. When using a foam dispenser, for example a trigger spray bottle with a foam nozzle, a creamy, stable foam is formed, which also adheres well to vertical surfaces.

In the context of the present invention are fatty acids or fatty alcohols or their derivatives - unless otherwise stated - representative of branched or unbranched carboxylic acids or alcohols or their derivatives having preferably 6 to 22 carbon atoms. The former are particularly preferred for their vegetable base as based on renewable raw materials for environmental reasons, but without limiting the teaching of the invention to them. In particular, the oxo alcohols or their derivatives, which are obtainable, for example, by the RoELEN's oxo synthesis, can also be used correspondingly.

Whenever in the following alkaline earth metals are mentioned as counterions for monovalent anions, this means that the alkaline earth metal, of course, only in the half - sufficient for charge balance - amount of substance as the anion is present.
