Abstract

A sprayable cleaning agent contains a surfactant combination of one or more sarcosinates, one or more amine oxides and one or more fatty alcohol polyglycol ethers and can be used to clean hard surfaces. In a corresponding cleaning process, the agent is applied to the surface to be cleaned using a spray dispenser with a foam nozzle or a pump foam dispenser and can be removed with almost no residue or streaks.

Description

Of the The subject of this application is a sprayable cleaning agent for hard Surfaces, a surfactant combination consisting of one or more sarcosinates, one or more amine oxides and one or more fatty alcohol polyglycol ethers contains. This results in a nearly residue-free and streak-free cleaning of hard surfaces and also cleaning vertical surfaces facilitated.

at the cleaning of hard surfaces it is always desirable that the cleaning agent after successful removal of stains in turn completely is removed and possible dries residue-free. Especially on glass surfaces, dark tiles or glass ceramic hobs remain otherwise unsightly Streaks and streaks back, which only increased by Workload can be removed.

Farther It is desirable, especially with vertical surfaces, that the detergent be does not expire immediately after application, but a certain amount of time Stick to the dirt to get through as possible long exposure time to enable a better dissolving of the dirt. This can be accomplished, for example, by adding the detergent in the form of a stable foam. However, this foam should at the subsequent Wipe with a cloth, sponge, leather or other suitable substrate quickly crumble to the desired residue-free Cleaning even without wet wiping to ensure.

It was therefore desirable to formulate a detergent, which with good grease dissolving on one possible huge Number of surfaces with as possible long exposure time can be applied while strip and residue dries.

It It has now been found that a detergent with a surfactant combination from sarcosinates, amine oxides and fatty alcohol polyglycol ethers sprayable is, in particular using a foam trigger, and thereby residue dries.

object This application is therefore a sprayable cleaning agent for hard Surfaces, a surfactant combination consisting of one or more sarcosinates, one or more amine oxides and one or more fatty alcohol polyglycol ethers contains.

These Formulation has a good fat dissolving power and can be without residue and streaks without moist wiping remove. When using a foam dispenser, such as a trigger spray bottle with foam nozzle, creates a creamy, stable foam, which also on vertical surfaces good adhesion.

in the The present invention relates to fatty acids or fatty alcohols or their derivatives - insofar 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, those obtainable, for example, by ROELEN's oxo synthesis are also available Oxo alcohols or their derivatives can be used accordingly.

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